This is certainly about as dolla camp asJI have ever seen. Ifonnda supper at a French restaurant, kept, however, by Mexicans, anda bed in an old barn of a building, which had once been a hotel, bnt which was now like “2 banquet hatl deserted, Whose guests were fled, its garlands dead, And all butrats departed.” At least if any other living animals hesides myself and the above mentioned rodents were its tenants, that night they showed no signs of their presence. At Donglass Flat, where I spent the night of the 16tb.inst., 1 found more life and business than at any other point on my trip. The deep placer mining at that place is more prosperons now than at nny time within the last year. The lead of gravel is strnck nt depths ranging from 100 to 200 feet, and varies from six inches to six feet in thickness. Itis generally opened by vertical sbafts, through which the water is pumped out, and the gravel hoisted by water power. One company, the Dashaway, on the south side of the Flat, aud another on the north side, have opened tbe lead by means of inclined tunnels dipping iuto the lulls, whicb they consider prefernble. J was entertaincd for tbe night nt the honse of Mr. Hitchcock, there being no hotels in the place,a fuct whieb I did not regret. as it was the cause of ny forming the acquaintance of a very agreeable family, and passing a pleasant evening. AT ANGEL'S CAMP Business is beginning to look up, though there is still great scarcity of money. Severn! companies are now at work taking out and crnshing quartz, but want of space forbids my giving a full description of each. The ledges at this place are vety large, ond wonld doubtless pay well, if the rock was rich enough. Hight dollars per tou was the hest average that was being obtained by any mills at the time of my visit, while the number of abandoned mills and fixtures lying around. told, plainer than words, that more fortunes have been lost here than have been made. ‘I'wo inills were rooning at the time of ny visit, that of the Stickle Bros. of ten stamps, and that of the Angel Quartz Miniug Company of seventeen. Both of these mills are using a machine, the invention of Dr. Hall of Augels, for catching the waste amalgam from the hatteries. It is called the “Gleaner,” and consists of a shallow pan, conical in shape, lined with nmalgamated cop. per plates, which are so placed that the pulp discharged from the batterics runs directly into it in the center,and as the pan is kept revolving is discharged over the sides. The Superintendent of the Angel’s company told me that one-third of the gold saved iu his mill was caught in this pon. Three miles west of Angels is the mine of THE ALTAVILLE QUARTZ MINING COMPANY, This mine has heen opened to a depth of 140 feet, the lowest working level being 100 feet. At the surface there seems to he three or fonr small veins running in at north and south directions, nnd of various widths from a few inches to five or six feet. Some very ricb pockets have been found, tbe rock from which has heen worked in arastras. The avernge yield nf that worked under the stamps is set down by the Superintendent at $10 to $15 per ton. The millis of sixteen stamps and two arastras, and is driven by an overshot wheel, forty-eight feet in diameter, which is also employed to pamp tbe water from the mine, and hoist the ore. While at tins mine I was shown a pan of dirt taken from a crevice in the vcin a few days before, which contained abont $100 in coarse gold. If many such prospects ns that are found, the mine is certainly a rich thing. Lnrrived at this place on Monday morning, the 19th inst., and bave spent my time since jthen in lookiug at the copper mines of this .of Joue City. The claim consists of 1,800 neighborhood. 1 wish, however, in making a notice of them, to inclnde also a description of those in Amador county, The first of these . that I visited is that of THE COSUMNES CEMENT MINING COMPANY, Located at Copper Hill, about five miles west of Latrobe. ‘Vhe compuny at first consisted of 10U persons, citizens of Michigan Bar, who located a claim 20,000 fect in leagth, on a range of croppings running ina northwesterly and southeasterly direction. At Copper Hill the croppings nf the lode are probably 100 feet wide. ‘I'he main shaft is sunk near the west side of the vein, and by a fine chimney of ore about liv feet in fength nnd trom tbree to nur feet wide. ‘lhe dip ot the yein is nbout forty degrees to the eastward, and that of the chimney some fifteen or twenty degrees north, ‘The ore isa yellow sulphuret [ull of seams and cracks, nnd assays from .fourteen to twenty per cent. The shaft is 400 feet deep, the lowest working level 370 feet. Another chiinoey has been opened, some distance southeast trom the moin sbaft, from which n large amount of fine ore bas been taken. it is intended to sink another sbaft this sammer in no ceutral position, nud work both chimneys from it. (he ore and water are hoisted from the mine by a 25-horse power steam engine with reversible motion, and friction geared reels. ‘The Superintecdent, Mr. C. H. West, took great pains to give me information and make my stay agreeable. Near tbe Consumnes, ona parallel vein is the claim of the Oriental company. ‘hey have sunk several shafts, to depths varying from ten to 150 feet, with good prospects, having taken ont some very good ore, bot from some cause, probably mismanagement, thé inine has failed to pay, and has been ahandoned, at least for the present. THE NEWTON COPPEAa MINE Is located on the Jackson road, four miles east feet on a vein running northwest-and sontbeast, the croppings being visible forn distanco of 800 feet, nnd the vein the most regnlarly defined of any I have ever seen, ‘I'he dip of tha yein is nbont thirty degrees east. ‘The vein is opened to a depth of 155 feet, at which depth levels have been ron 270 feet north of the shaft and 215 feet south, developing a vein of solid yellow sulphurets of copper from twelve to thirty-four per cent., from two to cight feet in thickness, averaging nearly fivefeet. ‘There is no sign of “running ont” either end of the drifts, and prospects are that the chimney will _ prove to be of indefinitelength. C. ‘I. Meader & Co., purchased a controlling iuterest in this mine about a year ago, Dr. Newton, the Superintendent retaining his intcrest of 250 feet, nad one other of the former owners reserving thirty-seven feet, the others all selling ont, The steam hoisting works were completed about the first of last September, since which time 1,800 tons of ore, [rem 12 per cent. npwards, have been shipped. No ore bas heen taken out north of the shaft, -and only about ane-fourth of that in sight, south of it, leaving between 30,000 nnd 40,000 tons of No. 1 ore in sight, which may be taken out ina years’ tine if desired About 400 tons are now lying in sacks awaiting shipment. Adjoining the Newton, being an extension southward of the same vein, is the'Qak Hill claim. ‘This company have not yet strock the lead, and work has been suspended for some y months. J was informed, however, by Mr. C. B. Strong, of lone, the President of the com. pany, that work would soon he recommenced, Qn the south extension of this lode, Dr. Randoll has strnck very good lonking ore. and is enrrying on his prospecting with energy and good prospects. Yesterday I spent in exploring the two principal mines of this place, the Union nod Keystone, of which, and indeed of all the mines on this coast, the most important is the famous UNION COPPER MINE. The vein on which this mine is located lies ina northwest nnd southeast direction, and dipping to the eastward at an angle of sixteen to twenty degrees, the foot wall heing a dyke of serpentine, some twenty or thirty fest wide, and the hanging wall the ordinary slate of the country. The claim consists of 1,950 fcet, aod has been open fora distance of 800 feet from the northern end. The main shaft is vertical, and has reached a depth of 480 feet, with levels running each way ot depths of 72, 106. 150, 200, 250, 300, and 384 feet respeetively. A cross is being started for a level, at the bottom of the shnft. ‘The shaft ents the vein at a dcpth of seventy-two feet, at which point it is eight fcet wide, the chimney extending a distance of about 100 feet. Irom this down to the 250-foot level it steadily inereases in width until at that point itis from twenty-five to forty feet, the nvernge of this level and. the one next below heing nbont thirty feat. Qn the two lower levels, the chimney has not yet been strack. As far down as this chimney has heen traced, its length ie about the same (100 feet), while it dips to the northward, by the measnrement of Mr. Petheis)
