The chisel ram, 29in. long, mounted on the front of the housing in dovetail slides,is counterbalanced to take all weight from the working mechan-ism. The long, closed cap box holds the boring chisel rigid forrunning the latter at high speed without vibration, the drivingpulley being carried between two boxes and sleeved in the samefull length. The spindle sliding in sleeve prevents wear otboxes, and retains alignment against the heavy pull of the latter is controlled on the pulley by two idlers, one being.

Coal Lost Through the Stack.—Prof. W. F. M. Goss, givingresults of his test, estimates that of the 90,000,000 tons of coalconsumed by the 51,000 locomotives in the United States in 1906,720,000 tons were lost through incomplete combustion of thegases; 10,080,000 tons were lost through heat of gases dischargedthrough the stack; 8,640,000 tons were lost through cinders andsparks, and 2,880,000 tons were lost through unconsumed fuel inthe ashes. The figures indicate that there is considerable roomfor improvement in our present draft appliances.
