CYLINDERS end by a draft pipe with a very large flaring bottom. The ex-haust nozzle is 11^8 in. below the center line of the boiler. Theadjustable diaphragm plate is located in front of the exhaustnozzle. Cylinders.—The accompanying illustration will show the gen-eral construction of the cylinders, which are the largest everapplied to a passenger locomotive. The chambers for the 16 valves have been thrown 4 in. outside of the center lineof the cylinders in order to bring them in the same plane withthe Walschaert valve gear. The steam passages have, of course,been made liberal and designed with easy curves so as to beable to furnish these very large cylinders with sufficient steamat high speed. The exhaust passage is on the outside, steam be-ing admitted at the center of thevalve chamber. The port leadingfrom the valve chamber to the cylin-ders is almost straight and is iJ4 and 21 in. long where it entersthe cylinder. These cylinders meas-ure l22j/> in. in width
