The "Primer of Hydraulics," which has 

 The been published monthly in installment in 



Primer of the columns of THE IRRIGATION AGE for the 



Hydraulics past year, will be completed early in 1912, 



Nearly Ready. there being another installment in the 



December, 1911, issue. All our readers 

 are acquainted with this most valuable addition to the very 

 limited literature on the subject of hydraulics and cannot 

 help to see the great help such a book will be to the practical 

 irrigator or hydraulic engineer. The time is at hand when 

 the successful irrigator must have a knowledge of hydraulic 

 principles and must know how to apply them, and the "Primer 

 of Hydraulics" gives this information in a simple and pro- 

 gressive method. 



It begins with the very simplest operations in arithmetic, 

 algebra, geometry and physics and carries the student along 

 from one principle to another until all are mastered that 

 enter into the .solution of the problem. 



. Perhaps the most important feature of the book is that 

 a large number of practical problems have been worked out 

 as a guide for those who have similar problems to solve, 

 thus making the book doubly valuable as it stands always 

 ready to show the way how irrigation and hydraulic prob- 

 lems are to be analysed, and how to check the results. 



The book contains a large number of valuable tables, 

 most of which are entirely new and have never been pub- 

 lished. They will prove a boon to all those who will use 

 the book as it reduces the work of solving problems to a 

 minimum.
