The Mining and Scientific Press. cr proprietor. These are some of tite points in which there are serions variations. It may safely be said that n farmer owning a linndred acres of rich soit on a prairie within twenty miles of any large town of Illinois, is certaiu of being able to mako a very comfortablo living ; but a miner with a vein of anriferons quartz yielding ten dollars to the ton, within ten miles of a Californin town, is not certain of anything until he has examined the vein, its position, its size, the character of tho yeinstone and accompanying minerals, and tho proximity and qnantity of wood, besides n number of other particalurs. Tirese are some of the diversitics of circomstances which beset qnartz mining in different places, and render it impossible to give n statement of the expenses of taking ont rock, bnilding a mill and redneing the ore, applicnble to the majority of tho mines, It is nseless to uttempt to convey any precise idca about matters in which the variatious are so great between tho workings of different mines, and between the workings of the Bame mine at different times, All that can be dono is to collect the facts in regard to the operations of the mines apd mills of which we have reports, so as to Bhow the range.—Jvoss Browne's Iirst Repart Srvavtan Fact.—For mining purposes, Bays the simerican Artisan, gunpowder is now yery commonly exploded by means of a wire rendered incandescent by clectricity, Itappears, however, that certain conditions are required to insure success. In vacno the incandescent wire merely evaporates the sniphnr, but the presence of air in ever so small a qnantity, of nitrogen, or perhaps of any gas, prevents this, and thus renders the explosion certain. The evaporation of the sniphur is snpposed by some to carry off the heat which wonld be required for the ignition of the other ingredients.
