THIS book deals in a most clear and thorough way with im- 

 mediately practical problems from the farmer's, fruit-grower's, 

 and gardener's standpoint, while the principles which underlie them 

 are presented in a concise manner that will be most helpful in 

 building up a rational practice of irrigation culture and farm drain- 

 age. Special effort has been made all through the book to broaden 

 ideas of general soil management, even where neither irrigation nor 

 drainage is practiced. In the preparation of this book the author 

 personally inspected the irrigating ditches and practices of both 

 humid and arid climates in this country and in Europe, so that the 

 illustrations, which are largely photo -engravings, are also of a most 

 practical nature. 



Irrigation and Drainage includes under 

 Irrigation Culture, in Part I: The Extent 

 and Geographic Eange of Irrigation; Con- 

 ditions which make Irrigation Imperative, 

 Desirable, or Unnecessary; The Extent to 

 which Tillage May Take the Place of Ir- 

 rigation; The Increase of Yield Due to 

 Irrigation in Humid Climates ; Amount 

 and Measurement of Water for Irriga- 

 tion; Frequency, Amount and Measure- 

 ment of Water for Single Irrigations ; 

 Character of Water for Irrigation; Alkali 

 Lands; Supplying Water for Irrigation; 

 Methods of Applying Water ; Sewage Irri- 

 gation. Part II, Farm Drainage, includes 

 Principles of Drainage, divided into many 

 subheads and treated in a most clear and 

 thorough way; and Practical Details of 

 Under-draining.
