One engineman. Two men feeding crusher. One other man at crusher on odd work. Three men loading stone into carts to supply crusher. Two single carts with one teamster hauling stone to crusher. The number of teams required to haul stone to crusher depends, ofcourse, upon the length of haul. Sometimes additional men will be neededto pass the stone to the men feeding the crusher; on the other hand, if thestone is dumped directly into a hopper above the crusher so as not to re-quire handling, two men are capable of supplying a crusher whose capacityis 200 cubic yards per day. The labor of drilling a ledge obviously depends upon the quality andseaminess of the rock and the depth of the holes. Under ordinary condi-tions, a steam drill with two men can be counted upon to loosen consider-ably more rock than can be handled by
