Excerpt from Steam-Engine Principles and Practice The economics of the use of condensers with steam engines and of employing multi-expansion engines are next considered and are followed by a division on steam-engine efficiencies and how to increase them. The material in the next division, on steam engines of modern types, concerns the distinctive features, economics and costs of engines of the present day. The testing of steam engines is then treated. Following this are divisions on the management, Operation and repair of reciprocating engines and on the use of superheated steam in engines which, it is hoped, will be of great value to the engineer. Next, the selection of steam engines is discussed from a purely but broadly economic standpoint. Finally, a thorough treatment of lubrication is. Presented which, although it relates Specifically to steam engines, Should prove of general value also as it applies to other machinery.

Perfecting the American Steam Locomotive documents the role played by mechanical engineers in the development of locomotive design. The steam engine and the mechanical engineering profession both grew directly out of the Industrial Revolution's need for sources of power beyond that of men and animals. Invented in England when coal mining was being developed, the practical steam engine eventually found numerous applications in transportation, especially in railroad technology. J. Parker Lamb traces the evolution of the steam engine from the early 1700s through the early 1800s, when the first locomotives were sent to the United States from England. Lamb then shifts the scene to the development of the American steam locomotive, first by numerous small builders, and later, by the early 20th century, by only three major enterprises and a handful of railroad company shops. Lamb reviews the steady progress of steam locomotive technology through its pinnacle during the 1930s, then discusses the reasons for its subsequent decline.
