The accompanying photographshows one not made by us but built, and in use for a number ofyears at the Baldwin Locomotive Works, from designs of theirmechanical engineer, Charles E. Wolle. It works very well onsmall coal, but if a stick or a piece of rope happens to be in the. DRUM FEEDER IN THE BALDWIN LOCOMOTIVE WORKS coal there is trouble at once. The construction of the coalcarrier described by Mr. Little is also not new. The samedetails of malleable iron bucket, steel bar link chains, bushjoint, center pin for roller, and hollow roller have been used byus for a long time. We also take exception, as engineers, to one feature of thecoal handling arrangements of the Mersey Railway powerhouse at Birkenhead. Two hoppers for feeding coal are in-stalled, to avoid the risks (as Mr. Little says) of complete shut-down by reason of clogging of the coal in the feed chute; inother words, it seems to be taken for granted that the coal mustclog and that a man must be there to clean it out.
