The piping was carefully laid out so as to secure the best pos-sible results, the arrangements of the steam piping beingsuch that should a break down occur in any part of thepiping it would be impossible to cripple the plant. Shortturns and right angle elbows have been discarded andlong bends put in wherever practicable. The enginesare provided with a main free exhaust pipe which canbe used whenever it is found necessary to run highpressure. In piping for the feed water for the boilers there wereprovided three different ways for feeding the boilers,making it almost impossible that any accident shouldrend
