 Rural Science Series 



The first book to assemble and organize the known facts 

 of science in their relation to the profitable production of 

 plants, without irrigation, in regions of limited rainfall. 

 With accuracy and clearness the author discusses the dry- 

 farm areas, dry-farm soils and the storage of water in them, 

 tilling, plowing, fallowing, sowing and harvesting, crops best 

 adapted and implements most useful. The book will be 

 found well adapted to courses in this increasingly important 

 subject. 



The Principles of Irrigation Practice

 Rural Text-Book Series 



Although much of the writing on irrigation has been from 

 the engineering point of view, this book is written distinctly 

 from the point of view of practical farming. The author 

 has drawn not only upon his own intimate knowledge of 

 conditions in an irrigated country, but also upon all the 

 available literature on the application of water to land for 

 irrigating purposes. The effect of water on the soil, the 

 losses by seepage and evaporation, the service that water 

 renders to the plants and the practical means of employing 

 water for the growing of the different crops are all discussed 

 clearly and thoroughly. The book will therefore be found 

 an excellent one for use as a text in college courses on irriga- 

 tion, and will also be of great value to the farmer in irrigated 

 regions.
