SKETCH OF THE MILLS. Allison Ranch Situated on the Allison Ranch mine, was erected in 18oG and commenced running in October of that year, with eight stamps, to which four more were added in 1863. The mill now runs twelve stamps, is run by a 35-horse power engine, and when employed crashes for its owners, the Allison Ranch Mining Company. Blanket process. This is an excellent mill. Byers. Owned by John Byers, and erected on South Wolf Creek, three miles and one-half southeast of Grass Valley, this year. Has eight wooden-stem stamps, which are ran by water power. Cambridge. Located on Howard Hill, at the Cambridge mine. Erected in 1866, at an expense of about $12,000. Runs ten revolving, 900-pound stamps, the motive power of the engine being 35-horse. Capable of crashing nineteen tons of quartz in twenty-four hours. Blanket process. Owned by W. E. Dean, D. W. C. Rice, W. H. V. Cronise, A. C. Peachy, Con. Reilly, and others, who also own the Cambridge mine. The Cambridge mill crushes exclusively for the company. Coe Company's, This mill was completed on the Coe mine in 1885. The crushing is on a new plan—new at least for this place, being on the centrifugal principle. The amalgamating process is the Ryerson. The mill, owned by Messrs. Coe & Davis, of San Francisco, has not been tested to any great extent, and we are consequently unprepared to speak of its merits. Empire Company's, This magnificent mill, which is unquestionably the finest quartz mill in Northern California, was erected in 1888, on Ophir Hill, at a cost of $100,000. Suns thirty stamps, is propelled by an engine of eighteen inch cylinder and forty-two inch stroke, and the capacity of the mall is sixty tons per day. The main building is one hundred feet in length and ninety feet in width, with a boiler house eighteen by thirty feet. All the improvements in gold-saving, such as the newest styles of pans, settlers, etc., are here used. The Empire mill is owned by the Empire Mining Company, consisting of Captain S. W. Lee, of Grass Valley, J. P. Pierce, A. L. Morrison and A. H. Houston, of San Francisco. Eureka. This mill, situated on the Eureka mine, and owned by the Eureka Company, was put up in 1835 at a cost of about §20,000. It runs twenty revolving stamps, is capable of crushing fifty tons per day, and crushes exclusively for the Eureka mine. This is an excellent mill. Gold Hill. This mill, situated on the west bank of Wolf Creek, Grass Valley, was erected in 1852, by the Gold Hill Company. It has twenty revolving stamps, (substituted in 1863 and 1854 for old square stamps,) being propelled by a one hundred-horse power engine, and is capable of crushing from forty to fifty tons of rock in twenty-four hours. Under the new management, important improvements haire been made in the mill, such as adding new boilers, introducing rotary stamps, etc. This mill, which bears a first-rate reputation, is now owned by Hooper, Cronise, and others, and crushes rock from the owners' ledge, on Gold and Massachusetts Hills, and also does an extensive business in crushing custom rock. Hartery. Located on the Hartery ledge, about two miles south of Grass Valley. Erected in 1866 at an expense of about $10,000.

This mill does custom work, and is owned by John W. Larimer. Laton & Son's. On Union Hill, north bank of Middle Wolf Creek, about two miles in an easterly direction from Grass Valley, was built in 1865, and cost about $10,000. Runs eight stamps, propelled by a 20-horse power engine. Capacity, fifteen tons of rock every twenty-four hours. Blanket process in use, though the principal part of the gold is saved on copper plates. This mill, which is owned by B. B. Laton of Grass Valley, and C. A. Laton of San Francisco, is a custom mill. Lucky. On Howard Hill, on the Lucky mine, about two miles east of Grass Valley. Erected in October, 1866, at an expense of $13,000. Buns fifteen revolving stamps, of about nine hundred pounds each, and can crush thirty tons of quartz in twenty-four hours. Amalgamating done in the batteries, and blankets also used. Bun by a 50-horse power engine. Crushes for the company. Owners, Hamilton McCormick, E. A. Tompkins, W. D. Goldsmith, D. E. Osborn, G. W. Topliffe, Michael Williams, Edward Nuttall, and W. B. Taylor, who also own the Lucky mine. Merrimac. Located on Merrimac Hill, about two miles and a quarter from Grass Valley, on the Merrimac mine. The mill was erected in 1864, and the first crushing was done in January, 1865. It has ten revolving stamps, weighing about eight hundred pounds each; is propelled by a 30-horse power engine, and is capable of crushing fifteen tons of rock in twenty-four hours. The amalgamating is done in the batteries. The mill crushes for its owners, Thomas Findley, Henry Scadden, Joseph Woodworth, George D. Roberts, and A. E. Head. Cost of mill, about $15,000. Norambagua. Situated on Wolf Creek, near the Norambagua mine, four miles south of Grass Valley. This mill, which is moved by water power, running ten stamps, and capable of crushing fifteen tons of quartz in twenty-four hours, was built in 1851. Crushes rock from the Company's ledges—the Norambagua and Lone Jack. The amalgamating is done principally in the batteries, copper plates and riflles also being used. The sulphurets here have paid as high as two hundred dollors a ton. Norton's pans are used for grinding tailings. It is owned by A. C. Peachy, Judge Hoffman, W. H. V. Cronise, William Campbell, Alexander Stoddard, and others, who purchased the Norambagua mill and mine, last summer, for $100,000. North Star. At the French Lead, about two miles south of Grass Valley. Erected in 1866, on the mine of the North Star Company, at a cost of $30,000. Runs sixteen stamps, with a 50-horse power engine, and is capable of crushing twenty-four tons of quartz every twenty-four hours. Crushes for the North Star Company. Owners, John C. Coleman, Edward Coleman, William Hoskin, W. H. Rodda, John Rodda, Josiah Rodda, James Dodds, Richard Kitto, William Dunston, and Thomas Harper, who are owners of the North Star mine. Osborn Hill. This mill, on Osborn Hill, about two miles southeast of Grass Valley, was erected in 1864, at an expense of about $22,000. It has three batteries of five stamps each, and is run by a 50-horse power engine, which is capable of running double the present number of stamps. The mill can be used either for dry or wet crushing. Capacity, twenty tons of quartz (wet crushing) in twenty-four hours, and ten tons by the dry crushing process. Owned by the Osborn Hill Company, who purchased this mill and the Osborn Hill mine, from. Joseph Woodward and George Voges, last winter. Perrin's. Owned by Joseph Perrin, and situated near Wolf Creek Station, about five miles south of Grass Valley, is a saw and quartz mill, combined, and is propelled by water power. Was built in 1864; the stamps, five in number, being added in 1865. First crushing in January, 1865. This mill, capable of crushing twelve tons of rock in twenty-four hours, is engaged on quartz from, the Slate ledge, owned by Perrin & Colvin, and located near Forest Springs. Rocky Bar. Erected in 1856, on Massachusetts Hill, by the Mount Hope Company, of which Michael Brennan was agent at the time. Is a sixteen-stamp mill, being run by two engines, each 35-horse power. The mill, which is now crushing rock for the New York Hill Company, is capable of crushing forty tons of rock in twenty-four hours. Blanket process used. The Rocky Bar mill cost upward of $20,000. Owned by the Rocky Bar Mining Company. Sebastopol, This mill, originally located at Sebastopol Hill, was removed to the present locality, Boston Ravine, in October, 1863. It runs twelve revolving stamps, is propelled by a 30-horse power engine, and can crush twenty-five tons of rock hi twenty-four hours. The Sebastopol mill—one of the best custom mills in the township—cost about $25,000. It is owned by Benjamin McCauley, the Watt Brothers, and Mrs. John Connolly. Blanket process used in this mill. Smith & Northey's. On Little Wolf Creek, about one mile and one-half from Grass Valley. Erected in 1864. Runs eight square-stem stamps, each weighing nine hundred and fifty pounds, the motive power being a thirty-horse power horizontal engine. Blanket process adopted, the .interior arrangements being similar to those of the Sebastopol mill, with the exception that arastras are used for grinding sulphurets and amalgamating rusty gold instead of pans. The mill is capable of crushing sixteen tons of rock in twenty-four hours. Principally engaged on custom work. Owned by Robert Smith, John Smith, Edward Northey, and. Henry Morgan. Stockton's. On South Wolf Creek, about twelve miles from Grass Valley, is the ledge of Stockton & Co., who crush their own rock with an arastra, the machinery being propelled by water power. Union Hill. On Union Hill, about two miles from Grass Valley, erected in July, 1860. Runs twenty stamps, having a fourteen inch engine with two boilers. Capacity, forty tons of quartz in twenty-four hours. This mill, one of the best in Nevada county, cost $21,000. Crushes rock for the owners of the Union Hill mine and mil], consisting of G. D. Roberts, William McCormick, J. H. Gash wilder, and T. Findley. SKETCH OF THE MINES. Eureka Hill This hill, through which the Eureka vein runs, is about one mile and one-fourth from the town of Grass Valley. It was originally known as Eureka Mountain, the first location being made February 7th, 1851. The Eureka, which, as far as developed, has proved itself the richest gold mine in the world, is among the earliest quartz locations of this township, but its richness, notwithstanding it had been worked by various parties for a number of years, was not fully developed until the winter of 1883. The mine was owned at various times by B. L. Lamarque, Geo. D. Roberts and William Chollar, who failed to find it profitable; Lamarque, who had purchased the interests of the other partners, finally selling the mine in 1857 to Fricot, Ripert and Pralus, for a comparatively small sum. During the years from 1857 to 1863, the ledge was worked to a perpendicular depth of forty-eight feet, and during this period large quantities of quartz were taken out, none of which paid largely, while the greater portion of the rock failed to pay crushing expenses. Becoming satisfied at last that the ledge was really a good one, Fricot & Co. commenced sinking a vertical shaft in 1863, completing it to a depth of one hundred feet in 1864. The vein at this depth was large and well defined, showing an excellent quality of quartz. The company in sinking this shaft took out sufficient money to pay the expenses of erecting hoisting and pumping works, building the present magnificent mill, all at an expense of over $60,000, besides giving numerous handsome dividends to the three partners. From 1863 up to the sale of the mine, in the fall of 1865, the Eureka continued to pay largely, but the figures we have not been able to obtain. The vein runs in a southeasterly and northwesterly direction, pitching west of south at an angle of about seventy-eight degrees, the upper wall being syenite, the lower wall greenstone. The lowest level reached, which is now being worked, is at a perpendicular depth of four hundred and twenty feet, on which drifts have been run from the foot of the shaft about three hundred feet, one hundred and fifty feet each way, showing a vein averaging three feet in width and yielding rock which averages $48 per ton. The Eureka sulphurets, which are among the richest in Nevada county, are saved by the company, and are worked by Mr. Deetken, for the owners, who uses the Plattner, or as it is more generally called, the chlorination process. The sulphurets are divided into three grades or classes, being numbered 1, 2 and 3; No. 1 paying at the rate of $400 per ton, No. 2, $300, and No. 3, $214. The sulphurets are worked to within five per cent, of fire assay. Since the present owners purchased the Eureka, in the fall of 1865, as already stated, when they paid $400,000 in gold coin of the United States for it, to Fricot & Co., new machinery has been added, the working greatly increased, and an immense amount of first-class ore has been taken out. The gross yield of the mine for 1866 amounted to $596,053, the dividends during the same period being at the rate of $30,000 per month, or $360,000 for the year. With sulphurets on hand unworked and with expenditures for machinery and improvements about the mine, the figures show actual dividends paid by the Eureka in 1866 amounting to $432,000, or $32,000 over the purchase money. A one-fortieth interest sold in 1868 for $17,560. The mill has crushed on an average one thousand tons of quartz per month during the present year, and the monthly dividends have averaged $30,000. The monthly expenses of running the Eureka, not including repairs of machinery, etc., are $18,000. Working at the present time about one hundred and sixty men. A new incline shaft was recently commenced, which will be completed during the present season, and which will greatly facilitate the working of this extraordinary mine. The shaft is being raised from the three hundred foot level, and is being sunk from the surface at the same time. There are eighteen hundred feet in the claims. The owners of the Eureka, the best gold mine we have heard of in modern times, are J. B. Dickinson, Thomas Hope and Benjamin Silliman, of New York, Edwin Hull, W. II. V. Cronise, John C. Winans, Hilton Bulkley, James Freeborn, A. J. Pope, Robert F. Morrow, N. J. Hall, George W. Beaver, L. S. Adams, and Francis Berton, of San Francisco, William Watt, Robert Watt, J. Fricot, A. Pralus and S. Ripert, of Grass Valley. The Idaho Company's claims, consisting of thirty-one hundred feet on the vein, begin at the east line of the Eureka, on the left bank of Wolf creek. At the west line of the Idaho the lode crosses the creek and rims into a spur of the ridge dividing Little and Middle Wolf creeks, and thence into the main ridge. The lode has been distinctly traced for about one thousand feet, and can afterward only be traced by the country formation. Located in 1863. A law suit prevented the development of the mine for more than a year. Late in the fall of 1864 the company commenced sinking a shaft on the creek, near the line of the Eureka, and developed a large vein of quartz, twenty inches in thickness, which increased as depth was attained. This was merely a prospect shaft. Under the superintendency of Edward Coleman the plant for the permanent shaft and machinery were made on the south side of the creek thirty feet above vertically south from the croppings. This shaft was sunk to a perpendicular depth of almost one hundred and thirty feet, and a level was run almost twenty feet toward the lode, which has not yet been struck. The company stopped work when winter set in, but will resume operations this season. They will undoubtedly find a large vein, as the croppings immediately opposite the shaft are two feet in width, showing free gold. The Idaho is owned by Thomas Findley, M. P. O'Conner, Edward Coleman, Wm. Young, Capt. L. W. Coe, and others. The Maryland claims begin at the east line of the Idaho, running two thousand feet on the lode. A chimney of the Eureka appears on these claims, at which point the company have sunk a shaft forty-five feet deep, and have also made surface excavations. The lode in the Maryland claims only crops out for about two hundred feet, and then disappears. Owned by E. A. Fisher, E. W. Maslin and S. P. Dorsey. Beyond the Maryland, on the line of the Eureka, is the Grass Valley Consolidated Company's mine, more generally known as the O'Connor, a history of which will be found under the head of "Union Hill." One feature of the Eureka vein is the directness of its course, never varying, so that aside from the formation of the country indicating its course, it may be traced by compass. On the west of the Eureka are the Roannaise claims, embracing two thousand feet on the lode, commencing at a large out-crop on the fiat west of the Eureka Hill, at the west line of the Eureka claim. The lode maintains its size. An eighty foot shaft sunk, but no rock crushed. Quartz highly charged with sulphurets. Sold by Fricot, Ripert and the Pralus brothers to a New York company, about one year ago, for $25,000. No machinery erected yet. The conformation of the country is such, after the Roannaise croppings disappear, as to prevent the lode from being traced distinctly. The Coe Company, the Pendleton and the Moss companies, each having a large ledge on their claims, are supposed to be on the line of the Eureka lode. North of the Eureka lie the Hayward or Richardson lode, the Golden Rule, Golden Gate, Alabama, Baltimore, Last Chance, Mobile, and other quartz veins. Massachusetts Hill. That the distant reader, unfamiliar with the magnitude of our early mining enterprises may understand, if possible, the amount of labor expended, the weary years consumed in opening, developing and carrying out to a successful termination the working of a large quartz mine, we reproduce, with a few alterations, the history of the Massachusetts Hill, or as it is commonly known, the Watt mine, which appeared in the Directory of Grass Valley Township for 1865. The Massachusetts Hill having been a representative mine, and having yielded, up to the time Watt, O'Keefe & Co. worked out the vein to their square boundary lines, a little more than one year ago, three million dollars, and its general history being the history, save in minor details, of other first-class quartz mines in this township, we give it without further excuse or explanation: The hill lies about three-fourths of a mile southwest of Grass Valley. The first quartz discovery on Massachusetts Hill was made early in January, 1850, a short time after the first quart discovery on Gold Hill. Massachusetts Hill was named by William Chollar, who figured extensively in its early history. M. E. Baxter was the first Recorder, and the name of Wm. Chollar is the first on the records of Massachusetts Hill. The first records of the hill bear the date of January 13th, 1851, from which we quote: The lot shall be staked off with one stake at each corner, and the fifth one in or near the center, with the number and name of owner, and said lot shall be recorded when taken tip; and if sold, shall be transferred to the purchaser, and if any lot or lots are not worked by May 1st, 1851, they shall be considered forfeited. These formed all the laws of Massachusetts Hill which existed up to April 23d, 1851, when at another miners' meeting the laws were revised and these amendments added: Voted—-That all new claims located may be one hundred square feet, not to interfere with present claims. Voted—That all old claims be recorded by the 10th of May, or be forfeited. At another meeting the laws were more fully elaborated, and in the revised code the claims were laid out thirty by forty feet; and till April 13th, 1851, no alteration was made. The laws enacted on April 13th, 1851, allowing each claimant or claimants one hundred square feet to the claim, remained unchanged till the general district laws were passed in 1852, at which latter period claims were authorized to be one hundred feet on the ledge, with all the dips and angles. In the winter of 1850 the first quartz mill was erected by two Germans. It was a small, rude affair, run by water power, and stood near the site now occupied by the Lady Franklin mill, in Boston Ravine. It scarcely saved gold from specimens, and was, of course, soon abandoned. The next mill, a decided improvement on its predecessor, was built by Bacon and others, and stood where the Sebastopol mill now stands. Considerable gold was saved, but not enough to satisfy the too sanguine hopes of the quartz miners. Bacon's mill crushed custom rock, charging at the rate of twenty dollars per ton. Massachusetts Hill was worked at an early day to the water level, by several parties. Delano & Co., who were extensively interested on the hill, sold out in 1851 to Dr. J. C. Delavan, an agent of a New York company, known as the Rocky Bar, this company supplanting the Sierra Nevada Company. Delavan, as agent of the new company, erected a small mill on Wolf Creek, at the base of Massachusetts Hill. This mill was a system of wheels running in a circular box, crushing the rock on the principle of an old-fashioned bark mill. It proved a failure. Dr. Delavan was succeeded as superintendent by a Mr. Whitney, totally inexperienced in milling and mining matters. He was soon succeeded by Mr. Seyton, who opened the mine and took out a large quantity of gold. Michael Brennan, whose tragic history we give below, succeeded Seyton as superintendent in 1856. In June, 1855, the Company took out a large quantity of ore which averaged seventy dollars to the ton. The name was changed to Mount Hope Company, an incorporated concern-Brennan, a member of the original company, having been sent out from New York as superintendent. In sinking on a stringer, he took out enough gold to pay the stockholders a dividend of one per cent, on a million dollars. Elated with his success, he built the Rocky Bar mill, put on expensive mining machinery, and sunk the celebrated Brennan shaft, which last piece of work cost over thirty thousand dollars. Brennan worked the stringer down to a depth of about two hundred and sixty feet, finding it, on the whole, a very unprofitable job. In addition to the investments made on Massachusetts Hill, he had erected machinery on New York and Cincinnati Hills, both of which enterprises proved failures. He had borrowed large sums of money from Andre Chavanne, giving Mr. C. a mortgage on the property. At last, driven to desperation by a combination of business reverses, and in a morbidly insane mood, he committed the crime of murder and suicide. On Sunday, February 21, 1858, Brennan, his wife and three children—embracing the entire family—were found dead at the family residence. The corpse of the murderer and suicide, Brennan, lay on the floor of his parlor, that of his wife on a sofa in the same room, while the three lifeless children were in adjacent rooms. Prussic acid, which Brennan had procured in San Francisco and Sacramento, had been the agency in this wholsale life destruction. By Brennan's side was found a loaded pistol, cocked, with which, it is reasonable to suppose, he either intended to take his life in case he failed with the poison, or designed using should any parties detect him in his fiendish act and attempt the frustration of his horrible scheme. He left a letter explaining the cause of his terrible act, complaining of his bad luck, asserting that he could not bear the thought of leaving his wife and children to buffet disgrace and poverty, also expressing regret that he was unable to take his mother and a sister in Europe, who were dependent upon him for a maintenance, with him on his long journey. Brennan, who was an Irishman by birth, was a man of extensive erudition, and for several years was connected editorially with the press of New York City, officiating at one time as phonographic reporter for the New York Herald. In December, 1857, Chavanne, who had purchased a judgment against the Rocky Bar Company, came in possession of the property — about two months before Bren-nan's death. After Brennan's demise, Chavanne worked the mine unprofitably until April, 1858, when the Massachusetts Hill Company leased the pumping and hoisting machinery which had been used by Brennan on the Pratt shaft. This company, consisting of William and Robert Watt, Joseph O'Keefe and the late John Judd, commenced work in the latter part of 1855, under a lease from Joseph Woodworth. In November, 1853, the company purchased Mr. Woodworth's interest on Massachusetts Hill for $20,000. They had struck the ledge in April, 1856, and had had their mine drained by the Mount Hope Company, tinder contract from Brennan, paying for drainage at the rate of one dollar and one-half per ton of quartz from the time of striking the ledge to leasing the machinery from Chavanne. Their levels being worked out, and the machinery proving incompetent to do the required work at a greater depth, operations were suspended in this portion of the mine in September, 1858. The company then commenced operations in the northern portion of their ground, on Boston Ravine Flat, sinking a shaft, and pumping the mine by horse power. Worked successfully here till May, 1859. This year the company leased the Brennan shaft from Chavanne, and commenced the expensive work of connecting their mine with the shaft, consigning nine months in running tunnels, opening up new levels, and putting on machinery — completing this extensive job in February, 1860. During the remainder of this year, and up to January, 1862, when the mine became flooded, an average force of one hundred and sixty men was daily employed. While negotiations were pending for a renewal of the Chavanne lease, and while preparations were being made to erect large pumping machinery, the Mount Hope Company, of New York, brought suit against Chavanne for possession of the Rocky Bar mine and mill. This proved for a time a severe blow to the interests of Grass Valley, as work was suspended by the Massachusetts Hill Company, and a large force of laborers was thus thrown out of employment. Owing to the tardiness of litigation, the Massachusetts Hill Company remained comparatively idle till June. 1863, when (Chavanne having beaten the Mount Hope Company,) the lease was renewed, and preparations were at once made for erecting machinery at a cost of $30,000. In November, 1863, the Massachusetts Hill Company commenced taking out ore, and worked almost constantly up to 1865. In April, 1864, the Massachusetts Hill Company struck the ledge in the bottom of the Brennan shaft, at a point but a few feet from where Brennan had hopelessly abandoned work. The lowest perpendicular depth attained in the Massachusetts Hill Company's mine has been about three hundred feet. An idea of the immensity of the work performed in this wonderful mine may be found in the fact that the company have run over two miles of tunnels. Since November, 1863, about one thousand tons of ore on an average were extracted monthly from this mine, three hoisting engines being employed a portion of the time, while two were constantly at work. The ledge, like all master mineral veins, varied in size, pitch, and quality of quartz, yielding enormously at times, and again not paying the expense of extracting the ore. Taken as an entirety, however, the ledge proved itself one of the best in this State. The expenses of this mine, since November, 1863, averaged one thousand dollars per day. The ground was taken up in square claims, and not, as now, with the dips, angles and variations of the ledge. After the ledge was struck in the Brennan shaft, which we have already mentioned, the Rocky Bar Company commenced to work their mine thoroughly, continuing the work until a few months since. During the past two years between 5,000 and 6,000 tons of rock have been taken from this mine, a large quantity of which was first-class ore. The Rocky Bar Company own sis hundred by three hundred feet on the lode, the mine being under the management of A. B. Brady. The Rocky Bar, which is not being worked at the present writing, is owned by the Chavanne Brothers, of Paris, Hentch & Berton. Abel Guy, John B. Felton, and others, of San Francisco. The Stockbridge claims are on the east extension of the Massachusetts Hill lode, embracing six hundred and sixty-three feet on the vein, including dips, angles and variations. Located in August, 1860. The work of sinking a perpendicular shaft commenced in November, 1864, is now down 242 feet, and will have to be sunk about forty-five feet further before the ledge is struck. This shaft, when completed, will cost upward of $25,000. The sinking of this shaft was suspended when the company purchased the ground and hoisting works of the Massachusetts Hill Company, about one year ago. Shortly after this, work was commenced on an incline shaft, through which Watt & Co, worked, and the shaft was continued to the lowest level of the Rocky Bar claims. After having made arrangements with the last mentioned company for drainage, the incline shaft was completed and a level was run in about fifty feet, when the stoppage of the Rocky Bar Company's pump brought the labors of the Stockbridge Company to a premature conclusion. The ore taken out in sinking the perpendicular shaft paid at the rate of twenty-two dollars per ton. Owners of the Stockbridge are, Henry Silvester, John Trenberth, M. Langstaff, W. H. Rodda, Henry Fuchs, L. B. Clark, George Gephard, Robert Patterson, James James, and W. H. Mitchell. The Boston Ravine Company's claims, which are also on the Massachusetts Hill. ledge, were located in March, 1864, by Dan. Collins and others. These claims, which are in an excellent locality, embrace two thousand feet, taking in dips, angles and variations. Not yet opened. The Discovery claims, recently located by Con. Reilly, are also on Massachusetts Hill, and consist of ten square claims of one hundred feet each. Bounded on the east by the Boston Ravine Company, on the west by the Massachusetts Hill Company, and on the south by the Donald Davidson ground. The Ford and Reilly Company's claims, on the Massachusetts Hill ledge, bound the Massachusetts Hill Company on the north, Scadden, Northey & Co. on the west, and the Stockbridge on the south. On April 1st, 1864, the owners, having determined to work their mine in a complete manner, commenced sinking a perpendicular shaft, which was continued to a depth of one hundred and fifty feet, where the vein was struck. It was worked on the Massachusetts Hill Company's line for a distance of about one hundred and ninety feet, from which six hundred tons of good quartz were extracted. The company have worked to a point below Watt & Co.'s level. This mine is owned by Con. Reilly and Martin Ford, of Grass Valley, and Patrick Riley, of San Francisco. The Shanghae claims, on this hill, are in high favor, and during the past year have paid several handsome dividends. Boston Ravine Flat. This section lies between Massachusetts and Gold Hills, north of the former and south of the latter, and about one-half mile south of Grass Valley proper. The principal mine in this flat, which is a continuation of the Massachusetts Hill lode, is generally known as the Scadden, being owned by Thomas and Henry Scadden, John Treaberth, W. H. Ciift, and Edward Northey. Located, in square claims, in 1852, by Conaway, Woodworth and others. The mine has been worked extensively since 1857, during which time it has turned out immense sums of money. East of the Scadden mine are the Pratt claims, consisting originally of thirteen claims of one hundred feet each, the owners subsequently purchasing five hundred feet from the Dubuque Company. This mine has not been worked extensively, as compared with other quartz mines in the vicinity, yet it has paid well for the labor performed, showing a vein of excellent quartz wherever it has been stripped. The Pratt ground is owned by Medcalf Pratt, William Edmonds, and others. The Reiily claims adjoin the Pratt ground, and consist of six hundred feet on the ledge. Not opened yet. Owners, Con. Reiily, Dr. G. G. Tyrrell and David Murray. West of the Reilly ground are the claims of Joseph Williams & Co. New York Hill. This hill, two miles south of Grass Valley, is on the west side of Wolf Creek, on the Massachusetts Hill range, and is one of the earliest quartz locations in this district. The New York Hill Mining Company, whose claims embrace nearly the entire hill, is the result of a consolidation of the Larimer, Wilde, Fricot and Chrysopolis claims, giving to the company between three and four thousand feet on the New York Hill ledge, including dips and angles. From the claims, since 1852, not less than $500,000 have been taken. The present company purchased the ground about twenty months ago, and have been engaged ever since in pumping out the mine, erecting hoisting and pumping works, sinking a new incline shaft, and opening levels for future work. This shaft is now down to a depth of five hundred and seventy-five feet, the average grade being thirty-three degrees, the vertical depth being three hundred and ten feet. Dimensions of shaft, six by twelve feet in the clear, giving a double track. The company have a twelve inch pumping engine, a ten inch hoisting engine, a ten inch plunger-pump, and two bucket pumps, one an eight and the other a six inch. The company are now opening their third level, giving three sets of "backs" on each side of the shaft, and will soon be in condition to take out five hundred loads of rock monthly. Over thirteen hundred loads of quartz have already been taken out, yielding on an average $45 per load. The New York Hill rock is rich in sulphurets, giving at least three per cent., and the sulphurets ra,nge in value from $100 to $220 per ton. The mine is now pretty well opened, is paying handsomely, and from the extent of ground in the claims, together with the excellent facilities for working, it is justly ranked among the first quartz mines of Grass Valley township. Working at present about forty-five men. The owners are J. I. Sykes, John Anderson, A. B. Brady, George Johnston, P. H. Ford, R. Leech, Donald Fraser, H. Vignon, J. Vignon, L. MolRoguier, A. B. Dibble, and James K. Byrne, of Grass Valley, and E. G. Waite, of Nevada. John Anderson, superintendent. Between New York Hill and Massachusetts Hill is South Massachusetts, through which, runs the Black ledge, the property of David Watt and others. On this mine is extensive machinery, but the mine is not being worked at present. In sinking an incline shaft on the Black ledge, excellent quartz was found, and from this mine were taken some of the richest quartz specimens ever exhibited in this district. Running in a southerly direction, a half or three-fourths of a mile from New York Hill, and on the west side of Wolf creek, are a number of quartz veins, none of which have been thoroughly developed, but the conformation of the country is such that there can be little or no doubt that some of these ledges will one day be extensively and profitably worked. Wisconsin. Flat About three-fourths of a mile south of New York Hill, and lying between the latter and Wisconsin Hill, west side of Wolf creek, is Wisconsin Flat, in which is the celebrated Wisconsin ledge, located in 1854 by Joseph Davison, who gave it its name. Soon after the location the Wisconsin mine was purchased by Con. Reilly. In 1850, Mr. Reilly, Joseph Woodworth and three others erected a nine-stamp quartz mill, a pump and hoisting machinery on the ground, which cost $11,000. The same year a perpendicular shaft was sunk to the depth of sixty feet, and a drift was run for the ledge, from which seven hundred tons of quartz were taken out, yielding the splendid average of sixty-eight dollars per ton. In 1857, the shaft was continued to a depth of one hundred and ten feet, the expense of sinking a portion of it being as high as one hundred dollars per foot. The ledge was again found in the bottom of this shaft, and three hundred tons of quartz were extracted at this point. The following year work was temporarily abandoned on the Wisconsin. The mine became entangled in the meshes of litigation, and E. McLaughlin, George A. Montgomery and William Loutzenheiser, who had bought a judgment against it from one Woodville, came in possession of the Wisconsin in 1856. It was leased the same year to T. W. Campbell, of the Lone Jack, who, owing to the vast quantities of quicksand and water with which he had to contend, gave up the contract. For several years the Wisconsin, like other good quartz mines in this vicinity, was left comparatively unworked, the owners performing only sufficient labor on it to hold the mine under the quartz laws of Nevada county. Last year (1868) it was sold to Charles Leech, Nathan & Hoffman, Wm. Launder, George B. McKee, and Robert Smith, of Grass Valley, Col. Geo. A. Montgomery, now of Canada, retaining an interest in it. A one-eighth interest was sold in the Wisconsin, about eight months ago, for $10,000 cash. The owners have erected hoisting and pumping machinery, in the present year, at an expense of about $9,000. The mine was recently leased to a party of twelve experienced miners, for a term of three years, the lessees doing all the work, defraying all the expenses of mining and reducing the quartz, and giving the owners forty per cent, of the nett proceeds of the mine. The contractors have sank an inclined shaft to a depth of two hundred and twenty-five feet to the lowest level, drifting three hundred feet on the lode, from which they are now taking out rock which averages $100 per ton. The vein in this level is eighteen inches in width on an average, and the ore is first-class. The ledge has given an average yield of $45 per ton since the mine was first opened. The company own thirty-four hundred feet on the lode. In the last twelve months, the books of the company show that 1,400 tons of ore have been taken from the mine and worked, the different crushings ranging from $18 50 to $76 25 a ton, the average being $51. The sulphurets were sold at the mill, where the rock was crushed, at $90 a ton. Missouri Hill A short distance above Allison Ranch is Missouri Hill, the principal mine of which is the Hartery, consisting of nine hundred feet on the lode. Located in 1853 by Thomas Hartery and others. The mine was worked to a perpendicular depth of one hundred feet along the entire length of the ledge, paying well and regularly. Hartery purchased the interests of his partners, erected a mill, at an expense of $30,000, in 1857, put on extensive hoisting and pumping machinery, and by thus involving himself, and through general mismanagement of the business, he failed in 1858. William Loutzenheiser and Edward McLaughlin, of Grass Valley, who were among Hartery's creditors, attached the property soon after the failure. The mine was subsequently leased to George Lord & Co., who found the pump insufficient to drain the mine, upon which discovery the pumping project was abandoned. The contractors next commenced running a drain tunnel, which they abandoned, and which was completed by Messrs. Loutzenheiser & McLaughlin to a length of seventeen hundred feet. The Hartery mill was destroyed by incendiaries in August, 1860. Over $200,000 was taken from the mine previous to Hartery's failure. In 1865 McLaughlin and Loutzenheiser commenced working the Hartery on an extensive scale, and in that and the following year they erected a quartz mill and pumping and hoisting works, at an expense of about $15,000. In November, 1865, Loutzenheiser sold a one-fourth interest in the Hartery to Joseph O'Keefe, for $15,000, the former retaining a one-fourth interest. During the years 1865-6 the company reached a perpendicular depth on the lode of one hundred and forty-seven feet, drifting from their incline about four hundred feet. The rock was found to be unusually hard, very heavy expenses attending the taking out of quartz, and the company suspended operations last fall. The Hartery is now owned by Edward McLaughlin, William Loutzenheiser and Joseph O'Keefe. In the neighborhood of the Hartery are the Wigwam, Potosi, Omaha, Homeward Bound, and John Doran & Co.'s claims. Lafayette Hill. About two miles below Grass Valley, in a southerly direction, lies Lafayette Hill, through which runs the lode of the North Star Company, on which are erected very extensive mining and milling works. A history of this wonderful mine, which is certainly a first-class one, deserving to rank at least as the second quartz mine in this district, will prove interesting to the readers of this work, for which reason we re-produce a few facts concerning its earlier history, which have already-appeared in print, as well as giving a few new particulars kindly furnished us by the superintendent of the works. The lode was discovered in 1851 by a party of Frenchmen, H. Pellatier, now of Grass Valley, being of the number, and was early known as the French Lead. The vein was remuneratively worked by these parties until the fall of 1852, when six-elevenths of it were purchased by Messrs. Conaway & Preston, who at that time owned a twenty-four stamp mill on Boston Ravine Flat, .which had been erected in the fall of 1851. In the fall of 1852, immediately after the purchase, Conaway & Preston formed a joint stock company of the concern, under the name of the "Helvetia and Lafayette Mining Company." Into this company all of the shares in said mine, as well as the mill of Conaway & Preston, together with several of their claims on Gold and Massachusetts Hill, passed. The mine was worked by this Company from 1852 to September, 1857, in which latter year, owing to heavy expenditures, the company became deeply involved, their property passing out of their hands by Sheriff's sale, E. McLaughlin, of this place, being the purchaser. From 1853 to 1857, as we have been informed by one of the early owners of the mine, the yield was about $250,000. In February, 1860, the mine was purchased from Mr. McLaughlin by J. C. and Edward Coleman, J. C. Pascoe, and others, representing twenty shares, for $15,000. At the same time the name was changed to the North Star Company. Since 1860 up to the present time, embracing a period of nearly seven years, the North Star mine has been extensively worked, has had large sums of money expended in developing it, and has paid its owners large dividends. An inclined shaft, through which the greater part of the work has been done, has been sunk to a depth of seven hundred and fifty feet, giving a vertical depth, on the lode of about three hundred feet; a drain tunnel, commenced in 1862 and finished in 1864, running a distance of twenty-five hundred feet, was completed at a cost of $15,000; and to increase the working facilities of the mine a perpendicular shaft is now being sunk at a distance of five hundred feet from the incline, to strike the ledge, which will reach the vein at a distance of about one hundred and forty feet from the surface. This shaft will be completed in a very short time, and will enable the company to increase their force of miners about twenty. On the mine is a magnificent sixteen-stamp mill, now running twelve stamps, but which will run to its full capacity on the completion of the vertical shaft; besides which there are several engines, one sixty-horse power, for pumping, one ten-horse power, for hoisting, one twelve-horse power for hoisting and pumping, and a twenty-five horse power engine, erected recently, for hoisting at the new shaft. [To the credit of the owners of this mine be it said that all their machinery was furnished by Grass Valley foundries.] The machinery and works erected during last and the present year cost about $25,000. The lode runs in what our miners call greenstone, pitching at an angle of about twenty-seven degrees, the vein varying in width from one foot to six feet, showing an average width of about two feet. The North Star Company, for over six years, crushed at the rate of one hundred tons of quartz per week, using their old mill, but since the completion of the new mill, in August last, the average weekly crushings have been one hundred and fifty tons, or six hundred tons per month. The company own twenty-one hundred feet on the lode, with the angles and variations, besides one hundred claims on Weimar Hill, south of and adjoining Lafayette Hill; and they have sixteen hundred feet east of the new shaft, on the lode, nearly all of which is new ground. Now working five levels, and in the fifth or present lowest level, which, as already stated, is down three hundred feet perpendicularly, a drift has been run one hundred and fifty feet in an easterly direction from the inclined shaft. It is estimated that fully 30,000 tons of ore remain untouched in the reserves or backs, opened by means of drifts from the main shaft. For the five years preceeding January last the nett profit of the mine was over $500,000. The gross product for the last five months of 1866 exceeded $100,000, the yield for December of the same year being $26,000. The mine is now yielding a monthly average of $24,000, the expenses being $12,000 a month, showing a monthly profit of $12,000. About one hundred and fifty men are employed about the mill and mine. The sulphurets are saved by rockers and sold by the North Star Company to sulphuret workers at from $80 to $120 per ton. Following is a list of the owners of this most excellent mine: J. C. and Edward Coleman, Wm. H. Rodda, Josiah Rodda, John Rodda, Richard Kitto, William Hoskin, James Hoskin, and Thomas Harper. Edward Coleman is general superintendent of the North Star Company, and Wm. Hoskin has charge of the underground department of the mine. Other mines in this vicinity will be found mentioned elsewhere. Allison Ranch. About two miles and one-half south of Grass Valley, on Wolf creek, is the village of Allison Ranch, noted the world over for having one of the richest quartz mines yet discovered. The village itself, for which we now have room only for a passing notice, contains two stores, one meat market, two boot and shoe making establishments, three or four saloons, the works of the Allison Ranch Mining Company, and an excellent public school. The business of the village is supported, or rather has been supported in the past, by the laboring force of the mine. The mine itself is at present under a cloud, and owing to questionable management, as well as a lack of harmony among the owners, work was suspended early last fall, leaving the Ranch in a languishing condition. What policy the present owners of the mine may pursue, we have no means of knowing, but it is more than probable that under some management Allison Ranch will again resume its place among the representative mines of this district; for a ledge from, which millions of dollars have been extracted, which has been worked for years with great profit, and which has never been lost even in the lowest depth attained, must again prove rich and extensive unless every theory of geology is incorrect, every practical principle of quartz mining at fault. We will give an epitome of the history of the Allison Ranch mine from its discovery up to 1865, together with a few later items of interest furnished us by Philip Gallwey, late superintendent of the works: As early as 1852, John and William Daniel, and four others, who subsequently returned to Missouri, worked in the creek adjoining the present town. In 1853, in digging a tail-race, which was done by several of the present company, the ledge was found, but no particular attention was paid to the discovery. In July, 1854, Michael Colbert and James Stanton bought into the creek claims. The ground at this time was worked with "long toms" and paid well. During the same year, while working toward the upper end of the claims, the ledge was again struck. At this point, the ground was found exceedingly rich, but the owners, somewhat inexperienced in quartz mining, failed to attribute this to its true cause, the immediate vicinity of an extensive quartz ledge. One day in the fall of 1854, two of the partners traced the ledge a short distance down, but on losing it became discouraged, and all the company, excepting Colbert and Stanton, ceased work for the day. These two, having again found the ledge, took out during the day, from, the opening their partners had left, about a ton of quarts. An extensive "cave" occurred during the night, covering the ledge as well as a portion of the mass of rock thrown out. Work was now resumed on the creek, the exhumed quartz remaining untouched, until exposed by the action of the fall and winter rains, when, on examination, the rock was found studded with free gold. This pile of quartz, together with fragments forked from, the toms, amounting to about one and one-half tons, was crushed at Lee & Simpson's mill, about a mile below Allison Ranch, and yielded about three hundred and seventy-five dollars. Con. Reilly was employed to open the ledge, and at once erected a water-wheel and sunk an inclined shaft, following the ledge, to a depth of eighteen feet, in doing which, he demonstrated the correctness of his own views by taking out enough gold to erect the present Allison Ranch quartz mill. In October, 1855, a lot of rock, about eighteen tons, which was crushed at the Gold Hill mill, yielded about $6,000; and in December of the same year, sixty-two tons produced $23,000. From 1855 up to last year the mine proved wonderfully rich, during which time large sums were expended in erecting machinery, sinking shafts, etc., the owners, the meanwhile, receiving liberal dividends. The gross yield of Allison Ranch from its opening to the close of 1866, as the books of the company demonstrate, was between $2,300,000 and $2,400,000. The product for the three years ending December 30, 1865, was $1,000,000, and in 1866 about $200,000. [It should be borne in mind that only eight months work was performed in 1860, the company virtually suspending operations in September last, and entirely abandoning work early last winter.] The lowest depth reached on the incline is four hundred and seventy-five feet, giving a vertical depth on the lode of three hundred and forty feet. In this level the vein was drifted on a distance of four hundred and thirty-four feet, northerly and southerly, two hundred and twenty feet in a northerly direction, and two hundred and fourteen feet southerly. In the south drift the vein showed an average width of fourteen inches, and in the north drift eighteen inches. The ledge, which had been considerably broken up in this level, in fact showing for a tune what appeared to be two veins, came together in the bottom of the level. A portion of the quartz in this level proved very rich, but the greater part was found barren, running the company in debt. Assessments were required to defray the expenses of sinking for another level, but such assessments came not, and a majority of the owners concluded to suspend work, carrying their conclusion to an unfortunate end. The mine, as already intimated, must at no distant day be re-opened. The owners of the Allison Ranch property are Michael Colbert, William Daniel and John Fahey, of Grass Valley, James Stanton, of San Francisco, and James O'Donahue and Chas. Field, of Bangor, Maine. The first extension north of the Allison Eanch ledge (recorded as the Stanton ledge,) was located on February 23d, 1855, by the Franklin Company, consisting of twelve hundred feet. The mine was leased in 1860, by Orlando Jennings, who soon afterward erected hoisting works and two pumps on it. An inclined shaft was sunk to a depth of two hundred and thirty-four feet on what was then supposed to be the ledge, but which, according to the opinion of experienced miners, was in reality only a stringer. Work was continued until June 1st, 1882, from which time to the present, the mine has been idle. The sum of $24,000 was taken from the ledge, which amount fell greatly short of the expense of working the mine. The south extension of Allison Ranch (Stanton ledge) was located in 185S, by George Wallace and others, who toot up eight hundred feet. Several prospecting shafts have been sunk, the lowest perpendicular depth of any being about seventy-five fest. The croppings of the ledge were struck in the bottom of the deepest shaft, and about the same time, water was found, which caused a temporary abandonment of work. A drain tunnel, commenced in 1861, from the west bank of Wolf creek, has been run a distance of three hundred feet, and will be continued during the present season two hundred and fifty or three hundred feet further. The present proprietors are, George D. Roberts, Con. Reilly, David Watt, Wm. Daniel, and Samuel Wittengenstein, the latter being an owner by purchase. Not being worked. In Vail's Ranch is the Phosnix ledge, which runs parallel with the Allison Ranch ledge, at a distance of about fifty rods. The Phoenix was located in 1861, by P. Hennessy and others, claiming one thousand feet. Several crushings of the Phoenix rock have been made, the lowest perpendicular depth from which ore has been extracted being thirty-five feet, and the average yield has been twenty-five dollars per ton. The owners of the Phoenix are, P. Hennessy, P. Gallwey, John Colbert, Richard. Barry, John Fahey, and Thomas O'Rourke. Norambagua Mine. This mine is situated at Forest Springs, one mile south from the celebrated Allison Ranch mine, and three and a quarter miles from the town of Grass Valley. The vein runs nearly north and south, and dips to the east at a very low angle— from twelve to seventeen degrees. It is incorporated as the "Forest Springs Quartz Mining and Lumber Company." This company now own 4.800 feet on the Norambagua vein, and 3,000 feet on the Bourbon, a parallel lode, which lies a little west of the Norambagua. The inclosing rock is a very large-jointed variety of green stone syenite, which drills and breaks readily in mining—a very fortunate circumstance in the economy of working. This rock is considerably decomposed at surface, but assumes its true character below water level. The Norambagua vein has been extensively explored since 1855. It is a narrow vein, being rarely over ten inches and averaging, perhaps, four or five inches. It is composed of a blueish-white quartz, seamed and banded with arsenical and white iron pyrites arranged, in parallel zones, producing a ribbon-like structure. The gold is seen in delicate parcels interspersed in the mass, requiring careful observation to detect it; but sometimes it is seen more conspicuously, as a thin fibre wire cleaves in the vein. Its tenor of gold is high, ranging from $40 to $100 to the ton. This vein is unlike the general character of the Grass Valley veins, which, as a rule, are destitute of arsenic and white iron pyrites. Similar ores are seen, however, in Osborne Hill. The Norambagua vein has been opened by an incline shaft, sunk to a depth of five hundred and sixty-seven feet (to the fifth level) and is now going down, but the extremely low angle of easterly dip (12° to 17°) gives only about one hundred and fifty feet of vertical hight over the level named. The levels have heen extended about one thousand feet south and five hundred feet north of the incline, or in all, fully one thousand and five hundred feet on the horizon of the main tunnel. The lower level was, in March, 1867, about two hundred and thirty feet north and two hundred and twenty feet south of the incline. The ores, especially on the south, were remarkably rich, yielding in mill over $70 per ton, and assaying very much more. The drain tunnel, which connects with the vein at four hundred and ninety feet from its croppings, was opened through on the 7th of March, 1867, eleven hundred feet in length, and four hundred and sixty feet north of the incline, having been in process of driving for four years, or since 1882, and at a cost of over $40,000. This is an important work, offering an exit for all the ores in nearly five hundred feet of backs, and a passage for the waters above and below this level, thus reducing the task of the pump to hoisting from the lower levels to the drain level. From this level the ores can be delivered by gravity to the proposed new mill site. The mine is furnished with a new 60-horse power hoisting and pumping engine. The ore is hoisted tip the incline on a tram way by wire ropes. Most of the dead rock broken in taking up the vein is used to fill up the old stopes, thus saving the use of timber. The levels of this mine are walled up in solid stone in the most substantial and workman-like manner. The cost of mining and milling the ore is about $30 per ton. The reserves of ore appear to be very great in the Norambagua. The vein has exhibited remarkable constancy in its general characteristics-and gold tenor, but is said to have grown richer to the south in descending. The mine has been worked in former years in a very unsystematic and temporizing manner, exhausting all the available ores and then pausing for some months while the incline was sunk and new levels were driven. A short time since the property changed hands, and now, under the energetic management of Mr. W. H. Rodda, formerly superintendent of the North Star, the incline is being vigorously sunk, the drain level has been opened through, and the levels are being extended "both ways to explore new ground. The Bourbon lode, which is some five hundred feet in front (west) of the Norambagua vein, has remained, until lately, quite unexplored, except that from a shaft sunk upon it for a short distance, the ore was found of a promising character. Recently, work has been commenced on the Bourbon by tribute, the miners furnishing their own supplies and dividing the product with the owners. This is evidence that the miners entertain a favorable opinion of the value of the ledge, or they would not risk their labor and expenses on it. The Norambagua ores are reduced at the mill belonging to the Forest Springs Company, situated on Wolf creek, near the mine, and driven by a water wheel of twenty-eight feet diameter and four feet breast. This mill was built in 1851, has ten stamps, in two batteries, square heads and wooden stems. Amalgamation. in battery is used, with copper plates and concentration of the tailings on Bradford's vanning tables or concentrators; also with Norton's pans, to grind the sulphurets. The copper pans of these machines are found to act well in saving floating mercury and amalgam, as well as in effecting a satisfactory concentration of the sulphurets. It is surprising that they do so good word, for they are charged far beyond the capacity for which they were designed, are very poorly attended, and by neglect have become much worn and disarranged. It is a machine which, with good management, is capable of doing excellent work. Although this mill is one of the most venerable in California, it has lately been repaired and its performance in treating gold seems more satisfactory than its rude exterior would indicate. The pile of tailings collected near the mill, carefully averaged yielded only about $7 per ton in gold. The concentrated sulphurets are worth about $50 per ton. The amount of sulphurets in the Noramhagua ores is considerable, probably as much as three per cent. The capacity of this -mill for treatment is about fifteen tons per day. It is run on custom work when not fully occupied on Norambagua ores. Now that the Norambagua mine is opened by its drain tunnel, and has also ample hoisting power, it will be the policy of the company to mine ores to the full capacity of the mill. A new mill site has been selected and a new mill is talked of. The product of the Norambagua mine from September, 1864, to the same month in 1865, was $80,643. About four months of the year very little ore was crushed; eight men on a shift being all the force employed in taking out ore. It is the policy of the present owners to develop the mine in such a way as to have the explorations well in advance of the work of extraction, and at the same time to bring their mill up to its full capacity. Not one-fourth part of the ore-ground owned by the company on the Norambagua has been prospected, and the Bourbon ledge is as yet hardly opened, and yet the work of exploration on the former mine has been in progress for about twelve years. There is hence good reason to believe that this fine property will soon be productive, more productive than ever before. The advantage possessed by this mine in respect to drainage and the amount of ore available within a moderate depth, will be understood when it is remembered that (if the mean dip of 15° is preserved) before a vertical depth of five hundred feet under the drain tunnel is reached the incline shaft must be sunk over twenty-one hundred feet from the mouth of the shaft, measured on the slope. We find in this peculiarity as well as in the high tenor of gold, a compensation for the small thickness of the vein, which, it should be added, has all the characteristics of a true fissure veia, likely to continue unchanged in depth. The Shamrock ledge runs parallel with the Norambagua, being southeast of the latter about twelve hundred feet; located in 1860. Two thousand feet in claim. Vertical depth reached on vein, about thirty feet, and the ledge worked at various points for an entire distance of thirteen hundred feet. About seven hundred tons of quartz have been extracted, paying from $14 to $50 per ton; average pay, $26 per ton. Ledge averages about ten inches in width. Owned by John Tierney, James Harrigan, Patrick Reilly, Patrick Hayes, and Anthony Copeland. The Perrin ledge, owned by Joseph Perrin and B. F. Colvin, runs parallel with the Shamrock, and is now being profitably worked. Water wheel used for pumping and hoisting purposes. The General Grant, same course as Shamrock, is a narrow vein, but is rich in gold. Last crushing, a few weeks since, showed an average yield of $50 per ton. Owned by George Little, James Harrigan; and others. Gold Hill Mine. This mine is on the hill after which it is named, and the claim calls for one thousand feet upon the vein. This mine has been celebrated for the large amount of gold which at various times since 1850 it has returned. It has had more than its share of the vicissitudes attending gold mining, but its history has not been recorded. At times the quartz has been knit together with gold which seemed to be distributed in this portion of the Massachusetts Hill vein in pockets. Those best able to know assert that there is a continuous communication in quartz between, the workings on Massachusetts Hill and Gold Hill, leaving, apparently, no doubt of the identity of the vein. Mr. Attwood, who worked the Gold Hill mine for a length of time, informed the writer that at times the quartz was completely barren or contained less gold than would return the costs of mining in one thousand tons, which, without any assignable reason, would again yield an almost fabulous product. Vast sums in "specimens" are known to have been stolen by the miners during the run of these bonanzas, in spite of all vigilance. It was this mine that supplied the quartz for the so-called Gold Hill mill, memorable and venerable among the quartz mills of California. It is a popular belief that Gold Hill, during the fourteen years of its history prior to 1865, had returned not less than four millions of dollars in gold bullion. From September, 1865, until September, 1866, this mine was idle. Since then explorations have been resumed with good unvarying result. This mine is explored by an incline shaft, which descends south 86 1/2° E (magnetic) to a depth, on the slope, of three hundred feet. For the first one hundred and forty feet this shaft dips at an angle of forty-fire degrees, until it strikes the vein, which it follows for one hundred and sixty feet more at an average dip of twenty-eight degrees. There is an adit or drain tunnel at the depth of ninety feet from the mouth of the shaft. The former explorations of this mine appear to have been extremely unsystematic and irregular, producing the impression to an experienced eye that the ups and downs which have attended it may be, in part at least, chargeable to want of skill and good judgment on the part of those who worked it. The older workings above two hundred and twenty-four feet are mostly filled up or inaccessible, and no trustworthy tradition of them are preserved. At two hundred and twenty-four feet depth on the incline is a drift running northerly one hundred and fifty-nine feet from the shaft; at two hundred and thirty-five feet depth is another drift running south three hundred and seventy-seven feet from the shaft; and at two hundred and eighty-seven feet is another, south eighty-six and a half feet, and north fifty-nine feet. Course of the vein and ore very crooked. In the two hundred and twenty-four feet drift north the vein is irregular, all the drifts below varying in size from a mere stringer at points near the shaft to six feet at one hundred and eight feet from it—but split into two parts with a mass of bedrock between—making an average of about two and a half feet of quartz. Over this drift it is believed the ground is mostly unbroken to the surface north of one hundred and eight feet from the shaft. The end of this drift is pretty wet. The two hundred and eighty-seven feet drift north shows stringers of quartz having bodies at times of considerable extent, and averaging about fifteen inches, the walls of the vein being from five to eight feet apart. No stoping has been done in this drift, which is very wet. South on the same drift, passing a block of twenty-five feet of ground from the shaft, believed to be of no value. The vein curves in irregular, mixed with perhapes eighteen inches of quartz, and some stoping has been done, averaging twenty inches from the bottom of the vein. About twelve feet from the end of this drift, or two hundred and seventy-five feet from the shaft, there is a fault, called by the miners, a "cross course," beyond which there is no vein matter, so far as explored, the hanging wall of the vein having dropped on the foot wall, which retains its position. This fault is nearly northwest and southeast, and dips steeply at about seventy degress. It contains no ore, being a mere seam, and the end of the drift is dry. The vein in the two hundred and thirty-five feet level south shows some good stoping ground, and the vein varies from two to three feet in thickness, being, in some places, as much as four and a half feet thick and very highly impregnated with sulphurets—as is also the hanging wall for a considerable distance over the vein. The vein carries in its wider portions a good deal of rock but is there also more highly sulphuretted. The tenor of gold in the vein at present is not very high, averaging about $15. The books show that 2,887 tons of ore, crushed from September, 1862, to March, 1867, gave an average yield of $13 05 per ton, the yield from the individual crushings varying greatly. This mine is furnished with .an engine, rated at 100-horse power, for pumping, and a hoisting engine rated at 25-horse power; both supplied from the same boiler at a consumption of about three and a half cords of wood in twenty-four hours. The pump is eight inch to the adit level, above that point to surface it is ten inches. The strength of the Gold Hill vein and its well known richness in former times, encourage explorations in depth and extent, with the reasonable expectation that the mine will at an early day resume its place as a dividend paying mine. There are now reserves standing in the stopes of about eight hundred tens of ore, and it is reputed that a considerable amount of good ore remains available also in the upper workings, which may swell the reserves to one thousand or twelve hundred tons. Meanwhile the incline is being sunk under the present management. Union Hill. This hill is two miles east of Grass Valley, and is separated from Howard Hill, with which it is parallel, by Middle Wolf creek. The Hill was made a matter of record January 30, 1851. The first and chief location on the eastern end of Union Hill ledge, was made by Dr. McMurtry, David Brooks, G. W. Woodward, and others, who afterward purchased several other claims. The company erected a Mexican arastra mill, and took out enough rock to defray all expenses. The mine was badly managed, as nearly all other mines were at that time. With heavy expenses and no experience in quartz mining, the company became involved. Judgments were obtained, executions were issued, and the mine was sold on April 6th, 1854, to Dr. Wm. McCormick, H. Hannah, and others. But little work was done on the mine beyond enough to hold it under the mining laws. Dr. McCormick, in 1865, became sole owner, selling interests the same year to Geo. D. Roberts, Thomas Findley and John Gashwilder, who are now the owners of the property. The latter part of 1865 the company put up hoisting and pumping works, and in the winter of 1866 sunk an inclined shaft one hundred and ten feet, and during the summer run drifts at that depth about seven hundred feet, two hundred feet west and five hundred feet east, the lode varying in width from one to sis feet, averaging about two and one-half feet in width, the rock paying from $12 to $80 per ton by mill process. In June and July of the same year the company built a twenty-stamp mill, which was kept running during the day time, from August 1st, the mine not being sufficiently opened to run the mill day and night. In September last they started the incline and sunk eighty feet deeper, and the tunnels were run on the lode east and west about one hundred and fifty feet each way, the rock being richer and the ledge wider—averaging nearly three feet. The company, at this time, were making preparations to run the mill day and night. When the severe winter set in they were obliged, on account of water and some of the machinery giving way, to temporarily abandon the mine about February 1st, 1867, until spring. They have now resumed operations at the mine and will run a drain tunnel, connecting with the upper level, which will take off all surface water and save the mine from being filled with water another winter. The average pitch of the ledge, which runs in slate, is at an angle of fifty degrees. The lowest perpendicular depth attained has been about one hundred and thirty feet. The company own three thousand feet on the ledge, with all its dips, angles and variations; in addition to which they own three hundred square claims; and they also own Wolf creek, for mining purposes, the entire length of their claims. They have on their claims, besides the engine for running the mill, one 12-inch engine for pumping and an 8-inch engine for hoisting, and two primps, one eight inch and the other fourteen inch, plunger and bucket. The machinery erected and attached to the mine cost about $40,000. The proceeds from this mine since starting the mill until work was suspended last winter, by water, were $74,413 41. Near the summit of Union Hill, and running in a north westerly and southeasterly direction, is the mine of the Grass Valley Consolidated Mining Company, now solely owned by Col. William O'Connor Sidney. This lode runs in hornblende, dipping westerly with an average inclination of about fifty degrees. The claim embraces twenty-five hundred feet on the vein, including, of course, all the dips, angles and variations of the lode. This is an early location, and was known at different periods as the McGrann, and the Murphy and the Bulger ledge. Colonel Sidney purchased the mine in January, 1883, from George D. Roberts, who had bought it from the original owners. A number of years ago the ledge was superficially worked by its locators, paying from $13 to $36 per ton, the rock having been crushed at the Gold Hill, the Lady Franklin and Laton & Son's mills. A tunnel was started about seven years since, and was run a distance of five hundred and twelve feet, where the vein, which was here narrow, was struck at a perpendicular depth of one hundred and twelve feet from the surface. In October of last year, an inclined shaft was started on the summit of the hill, at a distance of about five hundred feet northwesterly from the end of the tunnel. The incline is twelve feet by five in the clear, is splendidly timbered throughout, having a double track, and affording ample room for a large pump. The shaft pitches at an angle of fifty-five degrees, not varying the least in the inclination from the head to its present terminus, which is about one hundred and eighty-sis feet from the surface. At the foot of the incline, where a splendid looking ledge was exposed, the water came in with discouraging rapidity, and having no pumping facilities, work was temporarily abandoned. That no time should be lost, the labor of cleaning out the old tunnel, referred to above, was commenced. The tunnel, as already stated, had reached a distance of five hundred and twelve feet, under the old ownership, when the owners, who, by the way, were poor men and unable to thoroughly work the mine, became discouraged. Under the present management work was recently resumed at the end of the tunnel, the needed repairs were made, and upon putting in the first set of timbers, the ledge, showing a width of ten inches and looking very well, was discovered. The vein has been followed in this drift about four hundred feet in a southeasterly direction, the lode increasing in width and improving in the character of the ore as the work has progressed. A drift, started by the original owners, had been run about one hundred and eighty feet in a northwesterly direction from the head of the tunnel, and along this drift are several "chutes," from which the crushings already spoken of were taken. The northwest drift has been connected with the incline shaft, leaving the vein exposed for a distance of about nine hundred feet. The lode for the entire distance will average about two feet and one-half in width, showing generally a good character of quartz, and in the southeast drift is presented an excellent quality of ore, strongly resembling the Eureka rock, and strengthening the long accepted belief among practical miners that this is really the Eureka vein. The rock in the south-east drift is liberally filled with fine sulphurets, a portion of which sulphurets will yield at the late of $420 to the ton. The vertical depth of the present level will not average more than eighty feet. The work of sinking for another level, to a depth of one hundred and fifty feet below the present one, was commenced a few weeks since, and will probably he completed before this work reaches the public. Drifts will of course be run on the lode on this level for the entire length of the Consolidated Company's claims. A splendid 10-stamp mill, which can be increased five stamps when occasion requires, and extensive hoisting and pumping machinery have been erected within the past few months at an expense of $20,000. In the first level an immense amount of quartz, which could only be roughly estimated at thousands upon thousands of tons, is exposed—enough to keep a large, first-class quartz mill crushing for years. The second level, when thoroughly opened, will undoubtedly reveal another splendid body of quartz. Colonel Sidney has expended a large sum of money in purchasing this mine, erecting machinery, sinking shafts and doing what our miners call "dead work," but we believe that he is in possession of a first-class quartz mine, which will soon prove itself such. Dan. Collins is superintendent of the Grass Valley Consolidated Mining Company. The Pike Tunnel Company have one thousand and eight hundred feet on their claims. Located in 1883. Tunnel in a distance of one thousand feet, and the lode drifted on for one hundred and fifty feet, showing an average two foot ledge in width. Incorporated August 4th, 1865. Owned by E. Caldwell, Frank G. Beatty J. Newman, Nathan & Hoffman, and others. On the same hill are the claims of the Burdett Company, concerning which we can candidly say nothing of a favorable character, hence we prefer to dismiss the Burdett with the simple remark that it was sold for an enormous sum in the East, about two years ago, and the general impression is that the mine sold for every dollar it was worth. Howard Hill. This hill lies opposite Union Hill, on the south of Middle Wolf Creek, the western end being but a short distance east of Grass Valley, and it is a gravel, cement and quartz deposit. The first mine on the east end of Howard Hill is the Town Talk (gravel claim) which has paid handsomely in the past. East of this are the Independent claims, which have paid well as gravel diggings, and through which runs a quartz lode, on which the Independent Company claims two thousand feet. Incorporated December 10th, 1864. Owned by B. Nathan, H. Hoffman, J. Newman, Frank G. Beatty, H. Robitscheck and E. Caldwell. Traversing the hill easterly we next come to the Lucky Mining Company's works, situated on the company's ledge, the Cambridge. This location consists of about fifteen hundred and fifty feet. The vein, which was reached through a four hundred foot tunnel in 1862, runs in an northeasterly and southwesterly direction. In 1865 an incline shaft was sunk, and hoisting works were erected at a cost of $9,000. In 1866 a 15-stamp mill was erected at an expense of $13,000. The total amount of quartz taken from this mine has been 10,800 tons, and within the past two years the mine has turned out ninety-six hundred tons. About forty men are employed in the works. The company reduce about seven hundred and eighty tons of ore per month, at a monthly expense of $4,500. The inclined shaft, to which we have above referred, is down two hundred and seventy-five feet, the vertical depth being about two hundred and forty feet. In the lower level the lode averages three and a half feet in width. The Lucky is owned by Dr. E. A. Tompkins, D. E. Osborn, W. P. Goldsmith, M. Williams, E. Nutall, W. R. Taylor, and Major Topliff, of Grass Valley, and H. McCormick, of Nevada. W. R. Taylor, superintendent. Adjoining the Lucky on the east is the Cambridge mine, in which the former company first discovered their ledge. The Cambridge, this being the name of the lode running through both claims, was discovered in 1852. The Cambridge Company own sixteen hundred feet on the lode under the quartz laws of Nevada county of 1852. Prior to 1855, up to which period this mine was but superficially worked, and without the aid of machinery, fifteen hundred tons of quartz were extracted and crushed, showing an average yield of $25 per ton. The mine was sold to the present owners in February, 1866, at the rate of $5,000 a one-sixteenth interest. Since the change of owners the mine has been systematically and successfully worked. An inclined shaft has been sunk one hundred feet on the vein, at which point drifts were extended on the lode, easterly and westerly, for a distance of about six hundred feet, showing an average width of vein of twenty inches. The shaft is now going down for another level, one hundred feet deeper than the present one, and at a point now reached by this shaft, a splendid three-foot ledge shows itself. During the past year a substantial 10-stamp mill, together with pumping and hoisting works, have been put up at an expense of $22,000. Since December, 1866, (making allowance for stoppage by water, in February of the present year,) up to the present, about twelve hundred and fifty tons of rock have been taken from the mine. The mill is now crushing seventy-five tons of rock per week. The quartz has averaged $20 per ton. Lowest vertical depth from which crushings have been obtained, about one hundred and seventy feet. Working at present forty-seven men in the mine and mill. The Cambridge Mining Company was incorporated in April, 1867, with a capital stock of $256,000, divided into two hundred and fifty-six shares. Trustees, D. W. C. Rice, William Blanding, W. H. V. Cronise, W. E. Dean, Milton Bulkley and W. B. Cummings. The Oxford, consisting of eight hundred feet, and owned by Thomas Loyd and others, all of Grass Valley, runs parallel with the Cambridge. In these claims a tunnel is now piercing the hill for the lode. South of the Cambridge, on the summit of Howard Hill, is the ledge of the Frankfort Quartz Mining Company, consisting of two thousand feet. Located in July, 1862. Lowest perpendicular depth reached on the vein, through a tunnel, seventy feet. Now in with another tunnel five hundred and twenty-five feet, which will be continued sixty feet further to strike the lode. This will tap the vein at a vertical depth of two hundred feet from the surface. About two hundred tons of rock have been crushed, including croppings, showing an average yield of $14 to the ton. Work will be vigorously prosecuted in this mine during the present season. Owners, J. J. Dorsey, G. D. McLean, J. M. C. Walker, William Hobby and Charles T. Duval. Ophir Hill. This mining locality, one of the most generally known quartz sections in Nevada county, lies about one mile east of Grass Valley; and the principal lode, the Ophir Hill, which is now owned by the Empire Mining Company, was located by George D. Roberts and others in 1850. The vein runs in greenstone, in a northwesterly and southeasterly direction, dipping westerly with an incline of 30 degrees. The ledge was purchased by Woodbury, Park and others, in 1851, who owned a quartz mill where the Sebastopol mill now stands. Ophir Hill yielded liberally, but, owing to mismanagement, its owners failed in 1852. A short time after, this mine was sold at auction to John R. Rush, who bought one-half the concern, the remaining half being purchased by the Empire Mining Company. They built their first mill on Wolf Creek, in the winter of 1851 and '52, a short time before purchasing the Ophir Hill mine. Rush sold his interest in the mine for $12,000, to his late partners, on May 4th, 1854. The Empire Company worked the mine with gratifying success from 1852 to 1864, during which time it yielded over $1,000,000; and since it came in possession of the present owners, in July, 1864, (work being commenced by them in September 28th of the same year,) up to the close of 1866, $300,000 was extracted. In the same year 8,750 tons of quarts were reduced, producing $175,000, or an average of $47 per ton. A magnificent thirty-stamp mill was erected last summer, involving an outlay of more than $100,000, and $50,000 additional was expended upon a new shaft, hoisting works, etc. This shaft was unfortunately sunk in the wrong place, and the development of the mine thereby much retarded. Another shaft, sunk in the right place, has now attained a depth of four hundred and sixty feet on the incline, and drifts running along the lead six hundred feet—two hundred and twenty feet northerly from the old shaft, and three hundred and eighty feet southerly—connecting with the new shaft, show a splendid reserve of fine ore, the vein averaging three feet wide for the length of the drift. The present lowest level is four hundred and sixty feet deep on the incline, giving a vertical depth of about two hundred and sixty feet; and from here a shaft is being sunk one hundred feet deeper, to strike another level in the mine. The design is to keep sinking this shaft, opening other levels from time to time, thus supplying large quantities of reserve ore, and consequently increase the working force of this immense mine. The new thirty-stamp mill, of which we have given a description in another department of this book, has been crushing night and day for the past two months, reducing ore at the rate of forty tons every twenty-four hours, the rock yielding from $44 to $49 per ton. Notwithstanding the facilities afforded by the reduction works of the Empire Mining Company, which are unquestionably the best and most extensive in Northern California, the rock is now accumulating on the dump-pile, or in plainer language, the mine is daily turning out more quartz than the mill can crush. The force of men now employed about the mill and mine is one hundred and thirty. The mine of the Empire Mining Company ranks, and justly, too, among the first-class quartz mines of Grass Valley township. The company own about 1,500 feet on the ledge with its dips, angles and variations. The sulphurets pay from $80 to $100 per ton. The owners of this valuable property are J. P. Pierce, A. L. Morrison, A. H. Houston and Captain S. W. Lee. The Ophir Hill Mining Company's claims, lying north of the Empire Company's ground, and adjoining the latter, consist of five ledges, having one thousand feet on each in length. The company consists of sixteen shares, which are principally owned by George M. Norton ann Thomas Hardy. A vertical shaft, two hundred feet in depth, has been sunk by the present owners, striking the Ophir Hill vein. Drifts have been run about three hundred feet on the lode from this shaft, in northerly and southerly directions. The vein in the drifts averages eighteen inches wide, is of blue-ribbon rock, heavily sulphureted, and showing free gold. No crushings made at the present writing, but ore is now being extracted for reduction purposes. Messrs. Norton and Hardy have expended over $48,000 in opening this mine, and will have at least $10,000 more to lay out before the Ophir Hill is thoroughly opened. The mine is in an excellent locality, and we expect before 1867 closes that the energetic and enterprising owners will be well paid for their investment of money and time. Adjoining these churns on the north is the Donahue ground, which consists of eight thousand feet on the Ophir Hill lode. From their claim, which has only been, superficially worked, and without machinery, to a depth of thirty-six feet, over $60,000 has been taken out. Owned by Thomas Donahue & Co. In the same neighborhood are a number of square locations, but we have found it difficult, impossible even, to obtain any reliable data of Ophir Hill beyond what is given above. Hueston Hill Lies about midway between Ophir and Osborn Hills, being on the same range with these well known quartz localities. Hueston Hill, named after the Hueston Brothers, was located by Messrs. Stackhouse, Montgomery, the Hueston Brothers, and others, on December 14th, 1853. It was worked to the water level, paying well from the year of its discovery up to 1855. E. L. Tuttle, now of Grass Valley, purchased the mine in 1859, and in 1861 he sold to John Trenberth and others, who soon afterward erected machinery on it. William Clift and the Smith Brothers bought a one-third interest in the Hueston Hill in 1863. The explorations on the mine were shallow up to 1861, from which period the new owners began to go deep on the vein, their labor being rewarded by rich returns of gold bullion. The lode, of which the Hueston Hill Company own twenty-eight hundred feet, runs in hard blue slate, is small, not averaging over eight inches in width, but is exceedingly rich. The course of the vein is northerly and southerly, with a westerly dip of about thirty-five degrees. A depth of three hundred feet on the incline has been reached, in which level drifts have been run about five hundred and fifty feet. The vein being narrow, and the encasing rock very hard, the cost of extracting and reducing the ore amounts to about $45 per ton, notwithstanding which the company, in 1866, erected new hoisting works at an expense of $30,000, besides dividing about $60,000 among the members of the company. Since June, 1864, up to the present writing, (April, 1867,) the Hueston Hill mine has yielded upward of $500,000. In the lower level, ore worth from $130 to $170 is now exposed. Working sixty men. The Hueston Hill Company has had several tilts at litigation, but has been victorious in each case. The Hueston Hill is justly included among the first-class mines of this district. It is owned by Robert and John Smith. S. D. Bosworth, the Coleman Brothers, and S. W. Lee, of Grass Valley, and A. H. Houston, of San Francisco. North of Hueston Hill is the Madison Hill ledge, consisting of eight hundred feet, and owned by Rush & Laton. Worked but superficially, yet the quartz extracted, amounting to about one thousand tons, showed a gross yield of $80,000, or average yield per ton of $80. Osborn Hill. Osborn Hill, which lies about two miles southeast of Grass Valley, may be described as an immense spur or mountain ridge running north and south, being parallel with Wolf Creek, and covering an area of about one mile square. Through it run a number of quartz veins, the principal one of which is the Osborn Hill, located in 1851. The lode has been traced farther, perhaps, than any other in this district, preserving its characteristics through a distance of nearly two miles in length. The Osborn Hill mine proper has turned out as much money in proportion to explorations made on. it as any of our quartz mines—paying almost fabulously for years when the quartz interest of this section was considered on the wane—but we have been unable to obtain any reliable figures as to its gross yield. It was tolerably well opened in 1852, from which period up to 1857 it annually brought its owners large returns. But bad management ran the company in debt, there was a want of harmony among the managers, costly machinery had been erected, the mine became mortgaged, and in June, 1884, it was sold to Joseph Woodworth. The new proprietors erected a splendid mill on the mine in 1865, which, together with other improvements, cost $84,000. The ground has been extensively tunneled, shafts have been sunk on the lode, but the mine has not even to this day been well opened. The lowest perpendicular depth reached on the vein by an inclined shaft has been four hundred feet, giving a vertical depth of about two hundred feet, at which depth a drift was run one hundred and seventy-five feet, showing a lode of an average width of two feet, and of a good quality of quartz. The Osborn Hill Company own two thousand feet, according to the locations of 1852, on the lode, which runs in a northerly and southerly direction, with an average inclination westerly of forty degrees. Woodworth sold the mine, a few months since, to Robert and John Smith, Campbell & Stoddard, S. W. Lee, W. H. Hooper, and others, who will doubtless soon work it to good advantage. North of the Osborn Hill mine is the "Wheal Betsy," being on the Osborn Hill vein, and consisting of five hundred feet. This mine was purchased about six years since for $9,000. Several thousand tons of ore have been extracted at a comparatively superficial depth, showing an average yield of 040 per ton, some of the quartz reaching the high figure of $90 per ton. Hoisting and pumping machinery on the mine. Owned by John Byers, S. W. Lee and A. H. Houston. The Orleans claims, owned by the Smith Brothers, Edward Northy and others, lie north of the Betsy, and are in good repute, although not extensively worked at. present. On the summit of Osborn Hill are the claims of the Wide Awake Company, embracing four hundred feet. Four hundred tons of ore from this mine have yielded $26,000. On the mine there is an engine, also a pump, as well as an inclined shaft two hundred and seventy-five feet in depth, running with the ledge at an angle of forty-five degrees. The ore is of a bluish color, and is rich in sulphurets and galena. The vein has varied in width from four inches to four feet, and at the bottom of the incline it is five feet in width. Machinery put on in 1859. Owners, A. Salaman, B. McCauley, D. Watt and J. Brown. On Osborn Hill proper are a number of other claims, including the McCauley and Lee, Greenhorn, Alleghany, Jefferson, Lafayette, Cariboo, Daisy, etc., all of which have been more or less worked, several of them being regarded as full of promise. The Redan, owned by Dewey, Robinson & Co., is on Redan Flat, lying at the eastern base of Osborn Hill. The Sebastopol ledge runs parallel with the Osborn Hill, lying several hundred feet east of the latter. This mine, owned by the Watt Brothers, Mrs. Ellen Connolly and Ben. McCauley, was worked for several years quite profitably, and would probably be worked at the present time were not its principal owners engaged in other extensive mining enterprises. Before proceeding to the next division of this part of Grass Valley township, we will inform the reader that in the vicinity of Osborn and Ophir Hills are a number of other quartz veins, including the Lawrence Hill, Prescott Hill, Franklin Hill, Daisy Hill, and countless others. South Osborn Hill. Following is a brief account of mines on the Colfax road from Grass Valley, running parallel with the west sides of Ophir and Oshorn Hills: ONTARIO MINING COMPANY — On Smith's ranch, one mile south of Grass Valley. Located in 1864; length of claims, twelve hundred feet: average size of ledge, fifteen incites. Owned by W. K. Spencer, Dr. McCormick and Reuben Leech. Located on the west side of the Colfax road. ORLEANS LEDGE — Was located in 1858. Length of claims, thirteen hundred feet; average size of ledge, eighteen inches. Several tons crushed yielded $15 per ton. Situated on the west side of the Ontario Mining Company. FAIRPLAY MINING COMPANY — Formerly owned by Julius Fricot, is an early location; now owned by the New York Hill Mining Company. Several thousand tons of ore worked at a profit to water level. CHESAPEAKE COMPANY — Is a southern extension of the Fairplay. Size of claim, twelve hundred feet; located in 1865. Several tons of ore worked at a profit to water level. Size of ledge, six feet. THE DIAMOND LEDGE — Located in 1865: size of claims, one thousand feet; steam engine and pump at work. Work progressing favorably. UTAH MINING COMPANY — Located in 1858; size of claims, eighteen hundred feet; several tons of rock crushed; contains a long drain tunnel, steam engine and pump. Owned by Nathan & Hoffman, and others. BATON ROUGE LEDGE — Located in 1866 - size of claims, sixteen hundred feet; average width of vein, one foot. Prospects rich. STATE OF MAINE COMPANY — Is a north extension of the Galena claims; size of ground, one thousand feet; located in 1865. GALENA COMPANY — Adjoining claims to the Ione; located in 1856. Size of claim. eight hundred feet; partially worked to the depth of ninety feet; several thousand tons of rock mined. Now owned by the Watt Brothers. THE IONE MINING COMPANY. — The Ione ledge is a tolerably early location, dating back some ten years; was formerly owned by the Empire Mining Company, and sold with the Ophir Mine to Messrs. Lee & Co., in July, 1865. Captain Lee sold the lone ledge to Messrs. Curtis & Hunt, for $10,000. A vertical shaft was sunk in August, 1865, and the vein struck at a depth of one hundred and forty feet, and several thousand tons of ore were crushed, averaging $20 per ton, the vein varying from one to five feet. In March, 1866, a 10-stamp, first-class mill was erected, and an inclined shaft sunk at the bottom of the downright shaft to the depth of one hundred and sixty-five feet, carrying a body of ore three feet thick. The mine is now owned by Messrs. Sloss & Co., of San Francisco. THE UNION JACK COMPANY — Is the first southerly extension of the Ione; was located in January, 1865. Size of claims, sixteen hundred feet; worked profitably to water level, twenty-one feet; one thousand tons of ore crushed; ledge averaged four feet; was sold in April, 1866, for $50,000. The ledge is at present being mined to the depth of eighty feet, showing a continuous strong vein. Rock is now being crushed at the Ione mill, at a profit. Its present owners are Castle Brothers, Sloss & Co., and C. Felton, of San Francisco, and Judge Sykes, of Grass Valley. RAILROAD MINING COMPANY—Is the south extension of the Union Jack; located in 1865; size of claims, one thousand feet; but little work done—only sufficient to hold the claims according to the laws of the county. PKESQUE MINING COMPANY—Is situated on Le Bar's ranch, south of the Railroad Company. Size of claim, one thousand feet; was located in 1853, and has been mined to water level—a depth of thirty feet from the surface; carries a well defined ledge of one foot thick, and is pitching east into Osborn Hill. The last crushing paid $49 per ton. Extending farther south, to the southern boundary line of Nevada county, are veins or quartz lodes without number, some of which have been but superficially worked, while in others even the croppings have not been disturbed, and all these appeal eloquently to capital and labor. THE BEN. FRANKLIN-An early location, is on South Massachusetts Hill, the lode running northeasterly and southwesterly, dipping westerly at an average angle of forty-five degrees. This mine was formerly owned by the Empire Mining Company, who, from 1855 to 1857, according to the company's books, extracted $75,371 83 in gold bullion. It was purchased by George D. Roberts, who, in May, 1866, sold four-fifths of the mine to W. H. Bivens, W. H. Howland, W. H. Graves and O. F. Griffin, Roberts retaining the other fifth interest. The money taken out by the Empire Company ($75,371 83) was mined out without the aid of machinery, the hoisting being done with windlass. During the past year, under the superintendency of Mr. Bivens, a tunnel has been driven six hundred feet, leaving about one hundred feet to be run before the lode is tapped. The lowest vertical depth attained on the mine has been but seventy-five feet. The vein, on which the company own twenty-two hundred feet, varies in width from ten inches to four feet. The last ore extracted, taken from the old works, paid $90 a ton. Machinery will probably be erected on the lode during the present season, and a systematic and extensive development of the mine may be expected during 1867. Adjoining this mine on the north is another Ben. Franklin, a later location, and on the same vein. It has yielded well in the past, is now being explored on contract, and promises to give a good return. Owned by Michael Casey and others. The Washington Company's claims, which are also in this neighborhood, have been satisfactorily prospected during the past and the present years, and the owners have every reason to be satisfied with the result. Owned by Michael Colbert, Martin Ford, 3Dan. Collins & Co. Lone Jack. This mine, on Missouri Flat, about one mile south of Grass Valley, was located in 1855. In 1856 the lode was reached by a tunnel at a depth of fifty feet from the surface. It was purchased from the locators in 1857, by Lee and Simpson, who, in the following year, erected machinery on it. In the same year, 1858, it was incorporated under the name of the "Wisconsin Gold Mining Company," becoming a portion of the "Forest Springs Quartz Mining and Lumber Company," The Lone Jack was not included in the sale of the Norambagua, made a few months since, but is now principally owned by C. T. Wheeler, of Sacramento, one of the former members of the Forest Springs Company. It has been explored to a vertical depth of about three hundred feet, or six hundred and twenty five feet on an inclined shaft, where the lode averages eighteen inches wide. A small engime, 25-horse power, was found insufficient to perform hoisting labor, being able only to do the pumping of the mine; and work has been temporarily abandoned, to be resumed when, heavier machinery is erected on the mine. The Lone Jack is under the management of A. H. Murdock. A crushing of thirteen hundred tons of roek, made in 1862, paid at the rate of $62 per ton; and the gross yield of the Lone Jack up to the present time has been upward of $500,000. Greenhorn District This district lies about five miles east of Grass Valley, on the right bank of Greenhorn Creek. There are quite a number of large and prominent ledges in this district, the principal one being the Monroe, probably more generally known as the Greenhorn lode. Located in 1861. The Monroe was worked for silver, assaying largely, but returning meagerly. In. fact, it has been hinted that a liberal supply of silver half dollars came into requisition in forming a Greenhorn silver brick, but this is evidently an invention of the evil-minded, and we give the report without indorsing it. The claims adjoining the Monroe—Greenhorn proper—were worked for gold, one hundred tons of quartz yielding $6,000. None of the owners feeing practical miners, the claims were leased to Aughey Brothers, who commenced a tunnel, and sunk an incline forty feet from the bottom of the tunnel, taking out a considerable quantity of gold. It is in contemplation to erect machinery on this mine during the present season. The country is virgin forest, is well supplied with water, presents excellent mill privileges, and offers rare inducements to capital and labor. The Greenhorn lodes lie south of the celebrated Banner mine, which is in Nevada township, the Banner and Greenhorn Districts being separated from each other by a cement and gravel hill. General Mention of Mines. Below we notice briefly, and with less order and regularity than would be shown were we not now crowded for time, a number of quartz ledges in this township, soine of which have been explored with gratifying success, while, others have yielded prospects such as to warrant their owners in investing liberally in money and labor to develop them: The Bowery claims, on Lafayette Hill, consist of thirteen hundred feet, were located in 1864, the lode running parallel with the North Star Company's, "being seven hundred feet north of the latter. The owners are erecting hoisting works on the Bowery, and intend to thoroughly explore the mine through an incline shaft, which has reached a depth of over one hundred feet. Vein averages twenty inches in width. A crushing of three hundred tons of ore showed an average yield of $15 per ton. Owners of the Bowery, Childers, McGuire, Blodgett, and others. The Inkerman, on the same hill, is a modern location, (1864,) is near the 2forth Star, and is favorably regarded by quartz men. Claim consists of thirteen hundred feet. Worked through a vertical shaft to a depth of sixty feet, and also pierced by a tunnel, opening the mine for a length of four hundred feet, showing a well denned vein of an average width of twelve inches. The Inkerman, which will soon be extensively worked, has turned out some beautiful specimens. The Inkerman is owned by Joseph Clark, William K. Spencer, A. W. Campbell, W. H. Bailey, Dr. W. G. Millar, M. W. Boss, C. C. Smith, L. Childesr, of Grass Valley, and H. P. Jones, of San Francisco. The La Grosse mine, situated in Rhode Island Ravine, was located in April, 1866. An inclined shaft was sunk to the depth of twenty feet, showing a splendid lode of free gold and being rich in sulphurets. Had to abandon the working of the claims on account of too great a volume of water issuing from the vein. The claims embrace fourteen hundred feet, and run in a northeasterly and southwesterly direction. The owners are Wm. K. Spencer, Samuel Lock, H. J. Paine, M. Perrusich, J. H. McCrory, S. W. Gamble, Isom Smith and Thomas Cassin. The company have recently incorporated under the name of La Crosse Mining Company, with a capital stock of $140,000, divided into fourteen hundred shares of $100 each. The company have entered into articles of agreement with San Francisco parties to put up pumping and hoisting machinery on the claims, to be running by the first of July, 1867. The Diamond Company's claims, located on the southwest side of Osborn Hill, and consisting of one thousand feet, were relocated by the Norton Brothers in 1865. Discovered in 1859, when some prospecting was done, but operations were suspended on account of the mine becoming filled with water. A drain tunnel was run a distance of three hundred feet, striking the lode at a depth of sixty feet; forty tons of quartz, extracted from this tunnel, paid at the rate of $22 per ton. Encouraged by this yield, the owners last season put up machinery at an expense of $6,000, purchasing the machinery—from the Watt Brothers—formerly used on the Galena mine. An inclined shaft is now being sunk, showing a splendid vein two feet wide, the quartz being well filled with free gold. The owners contemplate erecting a 10-stamp quartz mill as soon as the mine is well opened. The members of this company are persevering, practical miners, who do all their own work, and the prospect is good for giving them a good return for their investment of time, money and labor. Members of the Diamond Company are, John Norton, William Norton, Reuben Norton, H. H. Rollins, Silas Whiting, E. Ricker, _____ Power, and William Noble. The Homeward Bound, located in 1854, is the south extension of the Lone Jack, and the claims embrace eleven hundred feet. Not developed below forty-five feet from the surface, where a well defined lode of two feet in width shows itself. The Homeward Bound is in an excellent quartz range, and as an evidence of the high favor in which it is held by experienced quartz men, we mention the fact that its recent owners, A. D. Tuttle, C. C. Smith, M. W, Ross, W. H. Bailey, C. C. Townsend and Albert Shepherd, have made a conditional sale of the mine to D. B. Hunt, late of the lone, for $15,000. Hunt is to open the Homeward Bound as soon as machinery can be got on the ground and erected. The Golden Rock Mining Company's claims, consisting of one thousand feet, are situated about one-fourth of a mile north of the village of Forest Springs, on the range between the Ione and the Norambagua mines. Almost $2,000 worth of work has been performed on this mine. Explorations have been made on the lode to a depth of eighty feet, showing $30 ore, the vein at this depth being about three feet wide. Machinery to be erected this season. Owned by A. H. Murdock, P. H. Brogan, and a party of San Franciscans, the latter being owners by purchase. The King Bee ledge, situated near the head of French Ravine, two miles southward from Grass Valley, was located in 1864, and embraces twenty-five hundred feet on the ledge, running northerly and southerly. This is a large sulphuret vein. At a depth of sixty feet, the ledge is three feet thick and solid, between good walls; the rock is very seamy, and may be denominated ribbon rock. The principal owners are Wm. K. Spencer, Thomas Loyd, M. P. O'Connor and E. R. West. The company intend putting up pumping and hoisting works during the present year. The Pacific Company's claims, Dromedary ledge, are on Wolf Creek, in the town of Grass Valley. Paid well formerly, but are not being worked at present. Union Company No. 2, consisting of twelve hundred feet, adjoining the original Union Hill. A shaft is now being sunk to strike the vein, and arrangements are being made to put up machinery. Owned by Joseph Reed, C. M. Willard, G. A. Jordan and Con. Murphy. The Badger Hill lode is half a mile east of Grass Valley. Located in 1853. Has paid splendidly at times, but has never been extensively explored. The lode is "spotted," and has yielded an immense amount of the richest of gold specimens. Owned by E. C. Webster, P. J. Brogan, Lind Brothers, A. Morehouse, B. Nathan and others. The Good Hope Company's ledge, on Rhode Island Ravine, a short distance from Grass Valley, on the west, was located in 1861. It lies one-fourth of a mile north of Gold Hill, and the opinion obtains that it is an extension of the Gold Hill. Several crushings have been obtained from the Good Hope, which have yielded from $25 to $36 per ton. Owned by a company of Germans, consisting of F. Schrakamp, J. Bruneman, and others. The Cincinnati Hill claims are located about one mile southwest of the town, embracing twenty-six hundred feet on the lode. Leased to William Chollar, John Bennett & Co., who are running a drain tunnel. Are taking out $40 rock. The Narragansett Company's mine, owned by Thomas Hardy, E. V. Hathaway, H. B. Potter, of San Francisco, and H. Woodcock, of Grass Valley, lies directly west of Kate Hayes Hill. Purchased, a few months since, from Fred. Jones. Hoisting works erected on the mine this season at a cost of $12,000. Hope Company's claims, thirteen hundred feet, situated on Echo Hill, and owned by William Beal, R. Simonds, E. Jeffery and R. Sampson. Will be thoroughly prospected this summer. Last crushing of Hope rock showed a result of $25 per ton. CONCLUDING REMARKS. Before concluding this department of the Directory, the compiler feels it incumbent on him to offer a few words of explanation to the readers and friends of the work. The history of the Grass Valley mines, which, if given in detail, would fill a volume much larger than BEAN'S HISTORY OF NEVADA COUNTY, have been collected and written at intervals stolen from pressing business, and our mining sketches have been necessarily condensed, partly from a want of time to elaborate on our wonderful mineral greatness, and partly in consideration of Mr. Bean, whose volume already contains more reading matter than is usually given in a business directory, and more than is profitable to furnish. The compiler is aware that ALL the mines of Grass Valley Township are not mentioned in these pages, but the fault is not his. An effort was made to get a history of every mine in this district; invitations were extended to quartz men through the columns of the local press, as well as through other channels, and a majority of our quartz operators cheerfully answered the invitations, and gave such information as they possessed, while others, either through ignorance or some selfish motive, preferred reticence in regard to their mines. The object of giving a mining history of Grass Valley Township was to let people abroad know something of our real quartz wealth, and not to distort facts, or "write up" mines for speculation; and this object has been, as far as our personal knowledge extends, honestly carried out. The mines not included in our histories were probably not worth mentioning, and perhaps it is better that composition was saved by having them left out. In the following able article, by Professor Silliman, three of our principal mines, the Eureka, North Star and Allison Ranch, are treated scientifically and practically; and the careful reader will probably detect some discrepancies between the Professor's article and our briefer sketches of these mines, which were written before Professor Silliman's manuscript reached us, or before we were aware that he intended to contribute a paper to this work. In justice to Professor Silleman, we here publish the fact that he personally examined the mines alluded to, made his examinations carefully and correctly, and his article, which was submitted to experienced quartz men of this place, is correct in every particular.
