This work is printed in a pearl type, and is so small, measuring
only 2½ in. by 1¾ in. by ¼ in. thick, that it may be easily carried
in the waistcoat pocket.

“It is certainly an extremely rare thing for a reviewer to be called
upon to notice a volume measuring but 2½ in. by 1¾ in., yet these
dimensions faithfully represent the size of the handy little book
before us. The volume—which contains 118 printed pages, besides a
few blank pages for memoranda—is, in fact, a true pocket-book,
adapted for being carried in the waistcoat pocket, and containing a
far greater amount and variety of information than most people would
imagine could be compressed into so small a space.... The little
volume has been compiled with considerable care and judgment, and we
can cordially recommend it to our readers as a useful little pocket
companion.”—_Engineering._

This work is not, in any sense, an elementary treatise, or history
of the steam engine, but is intended to describe examples of Fixed
Steam Engines without entering into the wide domain of locomotive or
marine practice. To this end illustrations will be given of the most
recent arrangements of Horizontal, Vertical, Beam, Pumping, Winding,
Portable, Semi-portable, Corliss, Allen, Compound, and other similar
Engines, by the most eminent Firms in Great Britain and America. The
laws relating to the action and precautions to be observed in the
construction of the various details, such as Cylinders, Pistons,
Piston-rods, Connecting-rods, Cross-heads, Motion-blocks,
Eccentrics, Simple, Expansion, Balanced, and Equilibrium
Slide-valves, and Valve-gearing will be minutely dealt with. In this
connection will be found articles upon the Velocity of Reciprocating
Parts and the Mode of Applying the Indicator, Heat and Expansion of
Steam Governors, and the like. It is the writer’s desire to draw
illustrations from every possible source, and give only those rules
that present practice deems correct.
