Longitudinal Section of Smol<ebox Showing Arrangement of theSuperheater and Throttle side outlets 15, and thence down through the steam pipes16 to the cylinders. The throttle casing, as will be seen from the reproduc-tion of the photograph, is, together with the throttle drypipe and the side openings, a single casting. The Type E superheater used also presents a departurefrom current practice, though it cannot be said to be adistinct novelty, in that instead of the usual 5-in. flue witha double return flow of the steam there is used a 33 Section of 2-8-4 Type Locomotive Showing Dry Pipe and Super-heater Connections flue containing a single superheiiter return and, insteadof a small number of flues grouped in the upjDer part ofthe boiler, there are 204 such flues and but 90 of theordinary 234-in. tubes; and these are at the edges andacross the top, filling in the interstices of the sectionalarea of the boiler where the 3j/^-in. flues could not beplaced, and thus adding to the heating surface. The opening for the superheater header in the smoke-box has a fore and aft measurement of 18 in., and oneacross the boiler of 69J/2 in. so that the header and boltsare accessible from the top. And, as will be seen from thefront view showing the superheater units, they are easily accessible fur removal when the netting has been taken out. Owing to the large diameter of the shell, clearanceswere not sufficient to place the air and feed-water pumpson the sides in the usual position. They have, therefore,been set back of the front bum
