Show INTER-MOUNTAI- N Saving Flour Gold. Many thousands of dollars have been expended in the effort to save the flour gold that is found along the Snake river in Idaho, but it is of such exceeding fineness that no process that has been tried has proved profitable. A machine is now in operation, however, which, it is claimed, is a complete success. This is the Acme amalgamator, the invention of Mr. W. F. Mitchell of this city, mention of which has several times been made by this paper. On the 20th of last month one of these machines was placed on the Golden Slipper bar, MINING REVIEW. lery salutes at San Francisco, New Orleans, St. Paul and Augusta, Me., the cannon being fired simultaneously by the pressing of an electrical button by Governor Morton. Ancient Gold Miners. The Incas of South America are among the most ancient of gold miners. The amount of gold and silver produced by them is amazing. Atahulapa, the last of their chiefs, bribed Pizara for release from prison by offering to fill with gold, as high as he could reach, a room 22x17 feet. These In Within two centuries it was generally used throughout Mexico, and then adopted in Europe, only to be replaced by more modern methods. Hand Rock Crusher. An account is given in Engineering Mechanics of a hand rock crusher that enables a person to quickly and easily crush by hand power to a fine powder the hardest ores. The lever has a rubber covering where grasped by the hand, and a rubber cushion where it strikes the bed piece, to prevent Jar and noise. The Jaws are three inches wide and open at the top one and inches, consequently a of rock 3x1 inches can be piece crushed. With the lower part of the inch apart, it is claimed jaws set at that forty pounds of the hardest rock can easily be crushed in one hour, and twenty per cent of this will then go through a No. 00 sieve. Screw up the machine and one can soon run through the balance to No. 60 or finer. three-quart- er 1-- 10 Eli Perkins recently made a lecture tour of Idaho, although the good people of that State have done nothing to justify such an infliction, and in a letter written at Boise for the Eastern press has apparently fully sustained his reputation for the narration of untruthful tales. For instance, he represents a Boise banker as saying that every solid, conservative bank in Idaho and Montana is solid for sound money; that the were opposed to free coinage, and Capt.
