182 The Mining andl Scentific Dress, Mining Summary. Most encouraging reports cobtinne to reach us from all parts of tbe mines, and we may look for large receipts of the preclous metals during the coming summer. The condition of the money market is especially favorable for an active prosecution of heavy mining operations, and large amounts of capital, both foreign and domestic, are seeking investment in that direction. We subjoin our usual summaty : OALIFORNIA, Trivrry.— William Roch, from Kelloga’s Diggings. Hay Fork, informs the Trinity Journalthat it has been a splendid working season, aud that water for sluicing will last until Augnst. The gold yield in that section will be large this year. , Vhis has nndoubtedly been . the most favorable mining season for most lo. calities in this county ever known. From present appearances, water will be plenty everywhere until July. Burrs. —Many rich mines ure now being developed in the vicinity of Forbestown, Butte county. The quartz ledges in that vicin‘ty are proving to be immensely valuable, and the extent of that mining section is said to be equal to any other in California or the world. Yousa._-The Templar Mining Company, No. 2, have let a contract for removing the Oregon City quartz mill from Oregon City, Butte county, to Indiana Ranch, in that county, to J. 1. Johnson. Nevapa—The discoveries of gold-bearizg lodes in Nevada county, during the past two or three years, have beeu unparalleled in the history of California mining, and what. is still better, there is no diminution or abatement of the good fortune attending the efforts of the “prospectors.” Says the Transcript of the 20th : “ Two more ledges were discovered and work commenced on them on Saturday last, at Willow Valley. ‘I'he ledges are of good size, and the specimens brought into town showed considerable amount of Tree gold, with any amount of rich-looking sulphurets. Willow Valley is fast becoming one of the richest niining localities in the county.” The Star Spangled Banner mill was started upon the 13th inst. We learn from the Gagelte that the millis of ten stamps capacity. The machinery, including tbe engine, etc., was manulactured at the Miner’s Foundry, Sau Franciscv, and is said to be a model of perlectiun. Lt was put up under the direction of Mr. H. L. Hopkins, an experienced machinist. The mine has the reputation of being one of the best in the connty, and itis said that the owners have refused 5150,0U0 fox the mine and machinery as it now stands. The Cement Mines of this, as well as other portions of the State, are creating an unusual omount of attention. Of these mines in Nevada eounty, tha Transcript speaks as follows :— “The Blne Cement lead crosses Greenhorn from Bonker Hill to Hunt’s Hill,and then runs parallel with the creek. It has been prospected as far as Jacobs & Sargent’s Green Mountain claims. In many places, as in Carley & Tucker's claims, the top has been washed off by hydranlic mining, and the lead is fur some distance laid bare. At other points it is worked by tunnels. The channel is from one hundred to three hundred feet wide, and extends entirely through Little York township to Gold Run, in Placer county. On this lead, within the past two years, some twelve or fiteen new mills have been built, and every week thousands of dollars are taken out, the proceeds varying from eight hundred to six thonsand dollars to the mill, We do not know of a single company which has erected a mill and failed in getting good pay. A company near Yon Bet eleaned up their flume on Saturday, 13th inst.,, and got uearly $12,000 after ten days’ ron. At Summit City, we learn that the Enterprise company has received all its machinery and will have the mill running by the second week in April. The only mill now at work is Winton, which is regularly empioyed crusbing for the Pacitieeompany. ‘he rock pays $50 per ton. ' Pracer.—During last. fall, says the Herald, quartz prospecting received quite a stimulus iu the vicinity of Auburn and other mining local‘ities of this section, from favorable discoveries made} but, the wet winter checked operations to a considerable extent. Some companies, however, continued work, ald at the preseut time, as appearances indicate that the protracted storms are over, we hear of very general preparations for renewing prospecting, We think more and better work will be done upon the quartz veins of this region, this summer, than ever before, and with results that will establish the character of our ledges as among the rich and reliable oues of the State. New locations continue to be made, and we have lately heen shown handsome gold bearing . specimens taken from some of them near at hand. The Auburn Stars and Sir tpes says that new and valuable quartz ledges are heing discovered in that vicinity every day, and many old claims known to be good re-opencd. All that is required to make tbis town eqnal to Grass Valley, is enterprise and capital. ‘The laborers are plenty. Who will furnish the nioney to obtain tbe rich treasures hid in the ground all about ahout us? The Dardenelles company near Forest Hill cleaned 532 ounces of amalgam, on the 19th instant. The Dewey claim, located nt Bath, clean up from twelve to fourteen hundred dollars weekly, over aud above expenses. Several other claims in the above localities are duing equally as well. Aminer at Long Cation, lately took out. after a 1uo of five wecks, one hundred and sixty ounces. TvuotumNE.—The App mine, according to the Sonora Democrat, has been sold to a company of capitalists for $120,000. Manrrrosa.—The Mariposa Mill commenced crushing rock on the 13th instant. The amount of rock to be reduced is about 300 tons, which will keep the mill running seven days. it is to be hoped that the rock: will pay sufficient to warraut @ continnance of work. Soxowa.—The Marysville Appeal is informed that geld in paying quantities has been discovered in Sonoma county, about five miles south of Cloverdale, eausing great excitement among the usually staid and steady farmers of that commonwealth, ‘The gold is represented as being quite coarse, oue uugget weighing five dollars. The Healdsburg Standard says that the mines thereabont are about to form a company and go to workin earnest. Water is to be brought in by a ditch, and the entire surface worked for placer gold first ; then the company intend prospecting for quartz. Thereisa large extent of country where good prospects inay be found, but the difficulty of getting water on fhe ground will always prove a barrier to profitable mining on tbe range. Los AncrLes —The Los Angeles News says that agents of capiltalists are in that victuity, with instructions to invest iuany mines there that they have good reasons to think will pay for working. The News adds that there are many rich mines in our section, and all that is requisite to develop their hidden wealth is capital. Copper, silver and gold, besides other netals, are to be fonnd in the three southern counties of Los Angeles, San Bernardino and San Diego, and in sufficient quantities to justily capitalists to invest their money to fully develop the mines. Our mineral weulth has received but a very small share of attention from those desiring to invest in mines—it was not far enough away fromhome. We trnst reason is resuming sway—that common sense will be heeded. Los Angeles county can produce coal of a good quality, and a fine quality of marble. Ia fact, the vast resources of this county are yet undeveloped—capitul is required. é ESMERALDA. We condense the following from the Homholdt Register : ‘the Manitowoc continnes to hammer out the bullion, though the workmen are at this time afoul of a orn, or barren spot. W. K. Parkinson, Superintendent of the Silver Bullion Series has got his men to work on this mine. Better late than never, but the mine onght to have been turuing out hullien long before this time. The editor of the Register has seen a beautiful silver bar, the prodnet of an even ton of quartz from the Hmpire claim, Sierra Distriet. ‘rhe company organized to work the Empire began the work of development under most flattering prospects. The claim is located on the Neptune Series, the group of ledges on which the TVallnluh claims, a short distance further up the ridge. The Honey Lake claim lies between the Empire and the Tallulah, and the several ledges crop boldly in all three— thus evideneing true veins. ‘lhe Empire company put down a shaft. and when satisfied of the reliable character of the ledges, commenced back in the cafion to ran a tunnel. This tunnel is one of the best looking pieces of work in the county—five feet wide, seven feet hich, and straight as a lead line. Thomas Ewing, owning largely in the claim, is trying to make . arrangements for resuming work. At his own. expense he took out this little batch of rock, . to see what Torrey could make out of it at the mill. Blake & Co. melted and assayed it, and it turns out 135.45 ounces. Value, silver, $142.38 ; gold, $5.59 —$147.97. M. Milleson is back, alter nearly two years absence from Humholdt. Ue comes out as agent fora New York company to direct work in several claims which Eastern capitalists . have undertaken to develop. The Esmeralda Union is informed that a New York company have purchased an interest in the Walker River mines, and are driving busiuess along in a highly creditable manner. Parties lately from Walker Lake, report that the mines are looking well and they are to have a mill erected immediately, which will test the matter more thoroughly. Wells, Fargo & Cv., shipped from their office in this place, over three thousand dollars in bullion by the stage of the 16th inst., the greater portion of which was from Blind Springs. The Antclope and Del Monte coinpanies on the same day, paid $4,441 in greenbacks ; delinquent taxes and costs. Of this amount, $3,871 were paid into tbe County ‘lreasury. The Kearsarge prospecting shaft is now 70 feet deep. and shows @ continuous lode of mineral. here is ore enough in sight to pay expenses of working, and which is estimated to be worth $250 to $400 per ton. ‘The Anglo Saxon looks well,as also does the Kenick. The Camanche still sustains its reputation, as well as the Dana. The Sierra Blanche Silver Company’s smelting works are completed, and will be in operation in a short time. VIRGINIA CITY AND VICINITY. A new miuing district, kuown as St. Mary’s, has recently been discovered, anc is creating sone excitement. It is ou the Henness Pass road, about ten or fifteen miles from the junction of that road with the Donner Lake road. ‘There will be a mill erected there this summer, and wood and water, the two great itenis of successful mining, are found there in abundance. ‘The Silver Peak district is also creating some stir among the mining population, coal having been discovered, and good looking quartz iu abundance. ‘This district is located on the Truckee river, near Baurs’ station, on the Donner Lake road. The Gould Hill News says that nearly all the mills in that vicinity are uow in full blast. There appears to be no scarcity of ore for crusbing. Our bullion shipments prove this. Tbe stamps clatter unceasingly—morning, noon and night the whistles seream, and everythiug is lovely. ‘Tbe Lnterprise says that the late strike in the ninth level of the Ophir is proving immensely valuable. ‘The deposit of ore is now (iu the bottom of the drift) 23 feet in width. or the first time in a long while we find the * dumps” of the Ophir filled with ore. Much credit is due to Mr. C. A. Luckhart, the engineer of the mine (mining engineer), for the discovery of this body of ore. We shall soon expect to see the Ophir hold its old place among the Washoe mines. About twenty tons per day of very rich ore is now being takén from the mines, and a much greater quantity will shortly be raised. Low grade ores are also being taken from some of the upper levels of the mine. : It is asserted by those capable of jndging pretty correctly that the body of rich ore lately struck in the Ophir extends into the Central ground, and will be struck when the works of the eompany Shall have beeu put down some thirty feet lower. Itis thonght that the deposit in the Ceutral will be found to be from twenty-seven to thirty feet in width. It will he a hig thing for the company as well as for the country. Considerable interest is at present being manifested in the southwestern mineral flelds of the State of Nevada. Many exceedingly tich veins have heen discovered in that section. Generally the leads are but from two anda half to four feet in thickness, but as they are (where worth anything) a solid inass of pay ore, they can be profitably worked, as it costs nothing for timberiug, and there is no waste rock to hoist out of the mine. The ores are generally chlorides, argentilerous galana and copper. Ores assaying lrom $100 to $400 4 ton are quite common. Mills are much needed. A correspondent of the Union, writing from Partawick, under date of March 10th, says that every day's work on the lodes of that .section prove more aud more conclusively the mineral wealth of that section of country. On the week previous, a specimen of seven pounds was hrought down from Elmira, one ol the Sierra Blanca company’s mines, which looked so well that it was determined to send it to New York. It weighed 317 pounds, aud will go to the Paris Exhibition, as the lavzest known specimen of silver ore ever found in that region of country. Sprer: Scuoon Norier.—J. C. Pelton, Superintendent of Public Schools, gives notice to parents and gnardians who desire to have their. children aud wards enter the Public Schools, . that they should make immediate applicatiou. to the Principals of the several schools, and have the names ot their children registered for admission. The Superintendent is determined . that any child who desires, or who can be induced to accept, a seatin our Public Schools, . shall be accommodated. If more seats are ueeded they will be promptly supplied. [Written for lhe Mining and Scientifle Press.j Silver Mining in Placer County. Sacramento, March 20, 1866. Ensrors Minine ann Serentiric Press :—It is now an established lact that there are silver mines in Calilornia, which, if properly managed, will pay as well as those of Nevada, if not bet ter, takiug into consideration the expense o working, the expense ol shipping machinery, of foel and of labor, also the distance from market and transportation, all of which are cheaper and of easier wccess in California, Working rock, of the same qnality in both places, pays better here. Now the qnestion comes up, have we rock of the same quality here. he lact is well known to some that: there is rock in Placer county that will range from $100 to $500 per ton, fire assay, both in the vicinity of Newcastle and Folsom. The silver leads at Newcastle were discovered by men who were working by night in the tunnel of the Kearsage Quartz Mining Company, and) went prospecting in the day time. There are two ledges running parallel, northeast hy southwest, and ahout two hundred feet apart The principal claims on those ledges are the Advalorem aud Camanche on one, and the Pacific on the other. ‘here is not much work being done on the Camanche at present, but ou the Advalorem, near the line of the Camanche, that company are sinking a shaft, and have reached the depth of filty-five feet, developing good ore, which, by roasting in a forge, will show glohules of silver ull over it, The Pacific company are down about forty feet, and have very good ore. Some ore frum both clainis has worked $64 per ton, mill pr cess. Enelosed you will find a certificate {fro Mr. Waters, of Sacramento, of an assay made by him of ore from the Pacific ledge, at a depth of twenty-eight leet. The ledge is fon feet and a-hnlf wide. and shows some of the tichest rockin this district, and the richest silver ore in the State. ‘There is no ntistake in regard to the quality of the ore; for by pntting it into the furge it will. in a few minutes, run the silver out of the rock. The ledge hag been visited by a great number ol people, and all are satisfied that it is very rich in silver, he mines are one mile and a-half from Newcastle station, on the Central Pacific Railrond. There is a good wagon road from the station to the mines. Covsideravle stock has changed hands this week. selling readily at $3 per Toot. T have sent you some of the rock from the Pacific, a portion of which is burnt, and Sone ag it came trom the mine. If you will examine the burnt rock with a glass yon will find that the cavities are lined with silver. [We can see plenty of silver without the aid of a glass.—Hns. Press.] You will also find gold in the clear rock. From one piece I lost a large kernel of gold, but you can still see some gold on the rock. Ene. The assay alluded to above is as follows :— Gold, 17 oz. to ton; Silver, 358 04-100 oz. to ton; value gold to ton, $3.51 ; value of silver to ton, $465.46 ; total value to ton, $468.97. Warers & Co. Sacramento, March 19, 1866, A CHOICE ADVERTISING MEDIUM, This week we issue an edition of 5,000 copies of the Youra’s Companion, every copy of whieh will he thoroughly scanned by more than one pair of sharp little eyes, and the eontents of every page, from first to last, will be re-uttered by many activ lively tongues in the presence of over 4,000 of the best families in this city and State. Although we are receiving many additional snbseribers to our list in response to the new enterprise in which we have engaged, we cannot expect, with the present high cost of printing paper, and our very low terms, to receive suffieient money from subscriptions alone 1o furnish as good a journal as we have determined to publish for our patrons; so we have widened the columns of the paper and adopted smaller type, which admits more lettors in” each line, and many more lines in each column of the paper, that we may have room for a few more select advertisements in the Companion without decreasing in the least any class of reading matter. Onur little journal eirculates in more families than any other weekly published in San Franeisco. No advertisements of the least objectionable character” will be received, And as but a Innited space will be devoted to this department, our young friends can safely inform their storekeepers, and other business + aequaintances of these important facts for the benefit of the paper and all concerned. Remember, only a few columns of our regular issue will be devoted to advertising, and the more profitable that class of patronage is made the greater will be the outlay upon our reading eolumns.

There are two ledges running parallel, northeast hy southwest, and ahout two hundred feet apart The principal claims on those ledges are the Advalorem aud Camanche on one, and the Pacific on the other. ‘here is not much work being done on the Camanche at present, but ou the Advalorem, near the line of the Camanche, that company are sinking a shaft, and have reached the depth of filty-five feet, developing good ore, which, by roasting in a forge, will show glohules of silver ull over it, The Pacific company are down about forty feet, and have very good ore. Some ore frum both clainis has worked $64 per ton, mill pr cess. Enelosed you will find a certificate {fro Mr. Waters, of Sacramento, of an assay made by him of ore from the Pacific ledge, at a depth of twenty-eight leet. The ledge is fon feet and a-hnlf wide. and shows some of the tichest rockin this district, and the richest silver ore in the State. ‘There is no ntistake in regard to the quality of the ore; for by pntting it into the furge it will. in a few minutes, run the silver out of the rock. The ledge hag been visited by a great number ol people, and all are satisfied that it is very rich in silver, he mines are one mile and a-half from Newcastle station, on the Central Pacific Railrond.

Sacramento, March 19, 1866, A CHOICE ADVERTISING MEDIUM, This week we issue an edition of 5,000 copies of the Youra’s Companion, every copy of whieh will he thoroughly scanned by more than one pair of sharp little eyes, and the eontents of every page, from first to last, will be re-uttered by many activ lively tongues in the presence of over 4,000 of the best families in this city and State. Although we are receiving many additional snbseribers to our list in response to the new enterprise in which we have engaged, we cannot expect, with the present high cost of printing paper, and our very low terms, to receive suffieient money from subscriptions alone 1o furnish as good a journal as we have determined to publish for our patrons; so we have widened the columns of the paper and adopted smaller type, which admits more lettors in” each line, and many more lines in each column of the paper, that we may have room for a few more select advertisements in the Companion without decreasing in the least any class of reading matter. Onur little journal eirculates in more families than any other weekly published in San Franeisco. No advertisements of the least objectionable character” will be received, And as but a Innited space will be devoted to this department, our young friends can safely inform their storekeepers, and other business + aequaintances of these important facts for the benefit of the paper and all concerned. Remember, only a few columns of our regular issue will be devoted to advertising, and the more profitable that class of patronage is made the greater will be the outlay upon our reading eolumns.
