eration 1t looks as if the marble quarry
 will be opened on a large scale, and II 1 so, the benefit to Columbia and the coun- ty at large cannot be overestimated.- | Tuolumne Independent
 With the early rains comes the begin
 ming of the end of the dry season that
 has been such great handicap to mining 1 operations. As soon as the water SUD-
 ply is renewed hundreds of stamps will go to dropping again and development operations will be renewed. Concerning
 the prospects of Tuolumne County the
 Sonora Union-Democrat says:
 And when the mining industry does
 resume in full blast it will be on an aug
 mented scale. Prospectors for months past have been consistently traversing the two mineral belts, and the conse- quence has been that many locations are now held under bond by men with capl- tai who are only too anxious to risk their dollars in development work. Among the already equipped properties many have l increased the capacity of their crushing plants, and almost all will have larger
 payrolls both underground and on top
 than ever before. It Is expected that
 when the rains have been sufficient to
 give enough water just for banning pUr-
 poses a great number of mines will
 be discovered throughout the vast dis
 tricts that have been burned over by
 laid bare thousands of acres of ground that for years past have been covered by impenetrable underbrush.'
 A discovery of natural coke" has been made in Tennessee Valley, Plumas Coun- ty. ProSpectors found vein 15 feet thick of coal formation. The same formation was again tapped at distance of a mile. the pieces for examination, say the sam pleS had been subjected to heat at some previous period, converting 1t into natural coke and that the article Is of commer- pi9l Vallp A test of 1en hounds in the Greenville foundry showed its heating qualities to be but four minutes short of the best Eastern coal.-Mfntng and Scien- tiflc Press.
 It has been published in the Bedding papers that the cyanide plant at Harri- son Gulch Is to be done away with and replaced by machinery for roasting ore. This is exactly wrong, and we are in- formed that the roasters are to be used to facilitate the work of the cyanide pro- cess in saving the gold from the tailings that have passed over the plates in the mill. The ore is reduced to sand by roasting that Is much more easily handled by the cyanide treatment for, extracting the remaining gold, and 1t is claimed that in this way S per cent of the gold can be saved.-Redding Searchlight.
 The Wedge mine has just struck an as- toniShingly rich vein of ore at a depth of $50 feet in the west drift It is peculiar looking, nothing like it ever having been IOQnQ III the camp IL IS ana ribbony in appearance and is sulphuret ore. It will mill s200 per ton. The Blackboard mine, just beyond the Stringer district southwest, Is developed into a fine prop erty. The ledge Is very wide, running five or six dollars all through with streaks of rich ore up to $10O per ton. The shaft is down 1& feet with drifts on both sides. Over at the Meredith mine in the slate range is one of the best and thor oughly equipped quartz mills in the State. | It Is the property of the Meredith Min ing Company of San Jose. They have a water pipe line three miles long. Some ore shipped to Selby at San Francisco | returned $215 per ton and altogether they have taken out over $25, 25,000-Randsburg | Miner
 The Coralie quartz mine in Calaveras | County has been bonded to 8 Chicago | represented by E. A. Converse. Development work will begin immediate ly, and as soon sufficient ore is blocked | out a small mill will be erected
 An Fl Dorado County correspondent of | the Mining and Scientific Press writes as follows concerning current developments of the great State resources of that re- zion: 'The Chili Bar slate quarry has been bonded to J. Hardy, who is in Lon- don organizing a company for the exten- sive operation of the property. He writes of his efforts. Work has begun on third slate quarry by w & Son within a mile of Placer v1lIe.
