This book covers a range of engines from the simplest oscillating engine to high-duty marine and small power enclosed engines. The illustrations are mostly of model stationary and marine steam engines built by the author. Points of general interest include reversing gears, lubrication - a subject which has been largely neglected - and a number of miscellaneous items (governors, lagging, splash guards, drain cocks, feed pumps, stop valves, saddle keys, etc etc). First published in 1958 and now reprinted.
