We concludedthat it was better to run the chance of some slight damage of thatkind than the more serious damage that would result from break-ing into the air duct and through the wall, at the same time prob-ably causing serious injury to the locomotive.—William Parkerbefore the New England Railroad CINCINNATI 22-INCH 38 AMERICAN ENGINEER AND RAILROAD JOURNAL. r ^ d ^^ \ \ \ < —^ C DIAGRAM ILLUSTRATING THE WORKINGOF THE DEVICE.
