PREFACE.

THIS Work is intended for the use of Engineers desirous of obtaining Certificates of Competency, either as Second-Class or First-Class Engineer, The Work is drawn up with a view to selfinstruction, or for the use of Schools.

It contains rules for working out the several Problems that are presented to candidates, with model solutions of, and numerous exercises to each Problem. A number of Examination Papers are also given. The chapter on the "Indicator" is illustrated by a large number of choice Diagrams, taken from Engines by the most eminent makers—including some from the Screw and Paddle Engines of the Great Eastern; H.M.S.S. Nile; the Iron-clad Research; the R.M.S.S. China; the Sea King (Confederate Cruiser); the S.S. Hansa, &c., &c.; also some rare and valuable ones from a Compound Marine Engine by Messrs. Rowan & Co., &c. This species of engine combines the various improvements of a high pressure of steam with superheating and surface condensation, and is reported by Professor RANKINE to have acted with a smaller consumption of fuel than has been hitherto attained in any engine whatever.

The mode of reading Indicator Diagrams is fully treated of, and also practical hints are given as to the important information to be obtained from them. It also contains chapters on Surface Condensers, Superheated Steam, Proportions of Engines, and such other related subjects as are required for the viva voce Examinations.

The Answers are given in full at the end of the book, with copious details of the intermediate parts of the solution.
