This is, of all the Hawkins books, perhaps the most useful to the Engineer-in-charge, to the Fireman, to the Steam user or owner, and to the student of Steam Engineering.

It is uniform in binding and size with "Calculations for Engineers" and the "New Catechism of the Steam Engine"; the size is 6 x 84 inches, 14 inches thick; weight 2 lbs. ; it is bound in green silk cloth, gilt top and titles in gold; it has 331 pages with 185 diagrams and illustrations.

See next page for further particulars relating to the practical subjects embraced in this valuable volume.

CONTENTS.

Materials; Evaporation; Fire Irons and Tools; Firing of Steam Boilers; Points relating to Fuels; Foaming; Chapter of Don'ts; Full descriptions of the Locomotive, Upright, Water Tube, Horizontal, and Marine Steam Boilers; Parts of a Boiler; Various Specifications for Construction of a Boiler; Riveting; Bracing; Various Repairs; Grate Bars; Boiler Cleaners; Boiler Scales; Boiler Tests; Scumming; Chemical Terms; Inspection of Boilers; Mechanical Stokers; Pumping Machinery; Feed Water Heaters; Steam Heating; Plumbing; Safety Valve Rules.

And many hundreds of other valuable pointers. for Steam Users, Superintendents, Engineers, etc.

No Engineer, Fireman or Steam User can afford to be without this valuable book, as it contains the pith and vital "points" of economical and safe steam production.

The plan followed in this work is the same as that so generally approved in "Calculations"; it proceeds from the most simple rules and maxims to the highest problems; it is both a book of instruction and reference. The carefully prepared Index contains nearly one thousand references, thus making it almost a dictionary of terms.

The work comprises the elements of Arithmetic, Mensuration, Geometry, Mechanical Philosophy, with copious notes, explanations and help rules useful to an Engineer.

And for reference, tables of squares and cubes, square and cube roots, circumference and areas of circles, tables of weights of metals and pipes, tables of pressures of steam, etc., etc.

This is a work of instruction and reference relating to the steam engine, the steam boiler, etc, and has been said to contain every calculation, rule and table necessary to be known by the Engineer, Fireman and steam user.

It is thus a complete course in Mathematics for the Engineer and steam user; all calculations are in plain arithmetical figures, so the average man need not be confused by the inser tion of the terms, symbols and characters to be found in works of "higher mathematics," so-called, yet the book is a complete treatise.
