Waring of Omaha, "but the strangest one 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 discovery dis-covery was made that is being used to good advantage. Some tin cans found their way into the small stream. In a 6hort time it was noticed that they had every appearance of being made of pure copper, so thickly were they covered with that metaL 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 filled with . all the old metal to be had in the town, including old barrel hoops. At the end of six months he found that the old junk was totally destroyed, de-stroyed, and in its place was a sedimentary sedi-mentary deposit in the bottom of the reservoirs which was 80 per cent copper." cop-per."
