Hence a feather- no room for the grinder to post himselfcomfortably between the dome and cab;or where the cab is so located as tosupply a convenient support for a tiredartisan. In the former case the seatwill be found to be low toward the back,and in the latter instance toward thefront of the stand pipe. I might addthat I have noted these defects time andagain in the old locomotive days on theelevated roads in New York City.

Editor: Mr. Kennedys remarks in the Augustnumber of and Locomotive weight machinist might have excellentluck with a very large valve, while aweary heavy-weight mechanic might de-velop in a small throttle valve all thedefects described by Mr. Kennedy. It is questionable whether extraweight thrown upon a throttle valve, orany similar piece of work in the act ofgrinding, is really beneficial. The ex-cessive weight speedily crushes the em-ery, possibly before it has performed itsfull abrasive work.
