Auriferous Gravel Deposits. Messrs. Enirors: While you are publishing much valuable information, regarding the more novel or attractive husiness of quartz niinin, allow me to give your readers a few words concerning tbagravel diggings of Yuba county, which inay be considered as more or less rep. tesentntive of an important branch of mining Eighteen miles northeast of Marysville, snc one from Timbuctoo, at Smartsyville, is located some of the best paying placer mites in th State. The mines are all gravel diggings, n¢ quartz being yet found in the vicinity worth prospecting. So valuable are the mines no in operation, that all the attention is tornet toward them, and all the interest is centered ) the development of new mines of the same character. he-rich pay dirt seems to extend through the center of a series of hills, a distance of.a mile or more from point to point ; lying along the bed of an ancieut river, whose level line hss probably been filled in hy som grent geological change. The local savant have passed their opinions as to prohable causes for the deposits and formation, leaving the unheliever to study out the evidence to the that the present mines occupy the hed of whit was once a river, and that the rich deposits 0 gold are the result of years of washings fron the surrounding hills and mountains, the gold being formed into, and held in the great natural sluice formed by tbe river bed. Evety indication of tbe action of water,such as heds of pure sand in lnyers ; conglomerate sand and gravel; smoothly washed boulders; deep washed lines in the bed rock ; also immense quantities of vegetable matter in various stages of petrifaction are here, indispntahie prools of the early conditions of the present mine. There is considerable irregularity in the general aspects, yet there seems to lave been three different deposits of matter, all differing easentially from each other. ‘Phe first is ut the lowest point next to the bed tock, and consists of immense beds of conglomerates, nade up of coarse gray sand and ordinary eohble stones. ‘Vhis contains the greatest quantity of gold, hardly a stone heing displaced without showing tho color. “Next in the ascending series comes the hlue gravel iu great quantities, and very rich also in depo-its ot gold. This formation in quantity far exceeds the first named, aud is the principal supply for the sluices. Vhe thirdis the surface, also conglonerate of sand and gravel, Itis red and rather: hadly decomposed, heing easily broken in the fingers. ‘This furmation contains the color, hut-falls far short of the yield of the othertwo. This, with a large supply of water and ground would pay well.for trouble and expense. “The miners here do not take much pains with the ‘surface, they simply crash enough from it to pay for the rémoval of the dirtiu their descent to the lower and richer heds. ‘ As the operations are the same in the various mines, a simple notice of one of the priucipal ones will give the reader a sufficient idea ot the workings of all, ‘he oldest-and most valuable mine here is the Blue Gravel claim. This ocenpies the center of one of the bills, and is evidently in the center of the old 1iver bed. It contains all three formations in slmost inexhaustible quantity, as the level of operations descends, the results increase. Not only does it show more dirt, but alco increased richness. From the top of the hill, to the lowest level, ina straight line, would measure * several huudred feet, and. so immense is the quantity of gravel that it promises to last for years to come, notwithstanding the vast amount daily washed off by the hydraulics and sluices. The observer, lor the first time, is struck with astonishment at the great amount of lahor expended on this niine, to develop it to the paying point, and can hardly believe the evidence of his own senses, when he sees a vast hill center burrowed out, and millions of tons of earth removed in so short a time, (The working of this mine-commenced in 1855). Tis idea of the force of water is made more comprehensive, yhen hy a moment’s watching he sees tons wsshed away while he expresses hia astonishment. The present ievel of the mine some hundred feet below the surface line, was opened a few years ago hy a tnnnel, 4 half mile in length., Through this tunnel a flume has been coustructed, running to the Yuha river a mile distant, through which all the dirt passes to the dump. ‘This tunnel is a fine piece of work and shows what labor, when well directed, will accomplish.
