 THE PRIMER OF HYDRAULICS 



BY FREDERICK A. SMITH, C. E. 



Hydraulic Engineer 



This book is now receiving the finishing touches and 

 will be ready for delivery by February 1, 1912, It is a 

 volume of over 200 pages of absolutely new matter pertain- 

 ing to the subject of Hydraulics and its allied branches. All 

 the subjects treated of are handled in a simple and prac- 

 tical way to make them of use to the men who have 

 been unable to obtain a college education, but who are 

 successful practical men in fields where they require a 

 knowledge of the principles of Hydraulics and instructions 

 how to solve their problems in a simple and satisfactory 

 way. This took is indispensable for anyone engaged in 

 works relating to Hydraulics, Irrigation or Drainage; it 

 is primarily designed for the practical man in the field, 

 but will be equally welcome to the trained Hydraulic 

 Engineer especially, on account of the many valuable 

 tables compiled by the author, which will save a tre- 

 mendous amount of time in computations.
