The two outsidejets are located so that the coal will be distributedalong the sides and the back corners of the fire-box. They are governed by separate valves toregulate the blast of steam through each valveby common steam valves, and can be adjusted atwill at any time. The steam that furnishes the blast to place thecoal is controlled by a quadruplex engine locatedon the back end of the boiler butt, which has acrank movement actuated by a screw wheel, oper-ating a control valve, which admits steam througha 1-inch pipe passing to the nozzles which areregulated by means of* a globe valve. The controlvalve, as a general proposition, is only run oneturn open, and va
