THE IRRIGATION AGE. 



The Great Divide 



KNOWLEDGE IS fHE GREAT DIVIDE BE- 

 TWEEN THE MAN WHO WpRKS AND THE MAX 

 WHO PLANS. The Civil Engineer is, above all others, 

 the pioneer of progress. Few people have any idea 

 how wide is the field of work allotted to him. That 

 field includes almost every phase of our industrial, com- 

 mercial, municipal and national life, and almost every 

 measure affecting public health, comfort or convenience

The work represents the combined efforts of a large staff of practical ex- 

 perts. It is admirably adapted to the needs of the beginner and self-taught 

 practical man in addition to meeting all demands of the technically trained ex- 

 pert. The various sections have been prepared especially for HOME STUDY. 

 Heavy technicalities and mathematical formulas have been avoided wherever 

 possible without sacrificing the absolute requirements of practical instruction. 

 The language is clear and simple; the treatment concise, yet exhaustive; and 

 the arrangement of matter convenient so as to carry the reader forward by easy 

 stages. Scries of test questions are inserted at the end of each section, enabling 

 the reader to test his knowledge as he studies, thus combining the advantages 

 of a text book and a reference work.
