We havebeen favored with the results of two of these tests which RAILWAY MASTER MECHANIC March, 1904. we reproduce herewith and it is but fair to say thatthe work here shown is being fulfilled as an every-daymatter.

Total average h. p. required r. March, 1904. RAILWAY MASTER MECHANIC 17 H. p. required to operate lathe ., H. p. required by the two cutting- tools. Work Note—Zenith tool in Ai condition after cutting acios-s Speed the tire; Novo steel tool in fair condition. Tools. Cutting Speed i8>4 ft. Per Minute. Pair of 84-in.
