Theseengines traverse curves of 8 degs. on themain line, and of 16 degs. in yards. The boiler used on this design is ofhigh capacity, with a wide and deep fire-box which is placed back of the drivingwheels and over the rear truck. The fire-box has a combustion chamber 65 , and the tubes have a length of 21 this construction the tube length iswell within the limits of good practice,and the furnace volume is large. Thearch-tubes are five in number, and theyextend from the throat to the back sheet. The bending of the two outer arch tubesis for the purpose of clearing wash outplugs and the opening left for the plugsis well worth the time and expense ofbending the tubes and putting the
