PREFACE TO THE SECOND EDITION.

The want of a second edition of this work has given occasion to correct a few errors, both in the text and illustrations.

The last two years have produced little change in the design of Valve Gear. The most noticeable feature is the growing tendency to place the Corliss valve in the covers, rather than at the top and bottom of the cylinder. Messrs. Turner, of Ipswich, have dispensed with trip gear on their Corliss engines, and employ a crankshaft governor to regulate the expansion. This appears to be a step in the right direction.
