Show A Queer Copper Mine.. "There are many kinds of mines and numerous inventions for saving precious pre-cious metals," fcaid Professor L. E. Waring of Omaha, "but the strangest Oiie i ever heard of is at Butte, Mon. When mines were first discovered in that locality, it was found that the water wa-ter contained in the fissures was so strongly impregnated with copper in solution so-lution that tools of all kinds were quickly quick-ly destroyed by the affinity of the copper for the iron. For a long time the water pumped out of the mine went to waste, as no method was known of extracting the copper from it After awhile a dis covery was made that is being used to irood advantage. Some tin cans found their way into the small stream. In a short time it was noticed that they had every appearance of being made of pure copper, so thickly were they covered with that rnetaL In noting this fact, one man resolved to try an experiment! He immediately purchased the exclusive right to the water. Then he put in a series of reservoirs and tanks along the little gully where the water ran. These he ailed with all the old metal to be had in the town, including old barrel hoops. At the end of six months h found that the old iunk writ: rnt-nlliT An stroyed, and in its place was a sedi men tary deposit in the bottom of the reservoirs which was 80 per cent cop-per." cop-per."
