PREFACE

In this little volume the publishers are offering to all who are interested a compact collection of principles, methods, formulas, and tables pertain`ing to the different branches of civil engineering. It is intended as a ready reference manual for the student as well as for the technical man engaged in practical work. For this reason, whenever there was a choice of rules or methods, only the simplest and those best suited to practical use were selected. For the same reason, wherever possible, examples such as would occur in practice have been given, together with their solutions, thus illustrating the different steps and processes to be performed in order to obtain practical results.

Attention is called to the tables, which are very numerous. Many of these can be found elsewhere only in special works, and many are origDinal, being found only in this book. Of the Alatter kind, are the Hydraulic Tables, giving the discharge, velocity, and head per unit of length for cast-iron pipes from 4 to 72 inches in diameter; and the Reinforced-Concrete Tables, by

111

means of which rapid computation of unit stresses in reinforced-concrete beams can be made for any combination of steel and concrete.

This handbook was prepared by Mr. C. K. Smoley, Principal of the School of Civil Engineering of the International Correspondence Schools.
