Show Miner's Cracils. The cradle is a simple appliance for treating "pay dirt," earth and gravel containing gold-dust. It consists con-sists essentially of a box, mounted on rockers, and provided with a perforated per-forated bottom of sheet iron In which the "pay dirt" is placed. Water Is poured on the dirt, and the rocking motion Imparted to the cradle causes the finer particles to pass through the perforated bottom onto a canvas screen, and thence to the base of the cradle, where the gold-dust accumulates accumu-lates on tranverse bars of ood called rimes." |
