considerable interest was tried on the Hudsen River
Rsroad at Sing Sing, on Tuesday last. Five passen-
eer-ca,s and one bsggae-car each provided with one
of w. G. Creamers patent g brake operators" were
attached to q powerful locomotive, and driven a. q
high velocity, TIL at given signal the steam
shut of and the brakes applied, to test their efficiency
az compared with hand brakes wen manned. Five
distinct trials made in three Of which the train
was stopped by the patent operators, aud in the re-
naming two by three stout brakemen.
The first tial We did not observe, except that the
patent operators were employed, and that the time
COZ sumed was l6 seconds and the distance run be-
