How to get th precious metal which lurk In Ihe bed of rlvera In th aouthweat I a problem which mining min-ing men are trying to (olv with tb dredge. A canal I being dredged through the auriferous gravel beds along tha Colorado river, Just north ot Yuma, and the gravel from th big coop I washed at the rear of the machine ma-chine In the water that follow from th river. Test ahow that th dirt contain about alxteen cent worth ot gold per cubic yard. With a crew of ten men the dredge cn handle aom 4.000 cubic yard dally. Although little lit-tle waa known of th Colorado rlrar gravel deposit until a year ago placer mining ha flovrlshsd for fifty year along th Colorado tributaries, which ar rich In gold.

Th richest atream, perhaps, Is th tlaasaynmpa river, which drains sever! sev-er! gold fields. A newly-Invented dredging machine which la expected to handle gravel at amull cost nnd extract ex-tract the gold by a dry proceaa, was lately put to work near Yuma. If It proves aucceasful there I a big field for It In Arliona. Over In New M-xl-co Thomas Kdlson'a scheme without using water ha been undergoing test for nearly a year. A company capitalized at $3.0o0.000 hn bought tract of land In the Orlls plazer rcxlun of that territory and hope to mskt immense fortunes out of it by the aid of ICcllson's Invention. |
