This work is not, in any sense, an elementary treatise, or history of the steam enjyine, 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, hf 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, Piston"^, 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.
