At the start of the work, the author in troduces hisintentionbehindthebook, expressingtheneedforarevisedand correctededitionthat reflects advancementsinsteamenginetechnology. He aims to bridge the knowledge gap for young engineers while maintaining practical relevance. The opening also discusses the book's organization into chapters for clarity and outlines essential elements relating to steam engines, such as the classifications, principles of heat and steam, and the many nu ances involved in engine construction and operation.

The usual configuration of those valves is that represented in figs. 42, 43, and 44; figs. 42 and 43 being a section and ground plan of the species of valve used by Messrs. Penn, and fig. 44 being a section of that used byMessrs. Maudslay. Itis important inthesevalves to have the india rubber thick, -say about an inch thick for valves eight inches in diameter. It is also advisable to make the central bolts with a nut above and a nut below, and to form the bolt with a counter sunk neck, so that it will not fall down when the top nut is removed. The lower point of the bolt should be riveted over on the nut to prevent it from unscrewing, and the top end should havea split pin through the point for the same purpose
