A luminous and practical discussion of the soil 

 and its various attributes. As an understanding of 

 the soil in some measure is of vital necessity to 

 success in even the most limited agricultural opera- 

 tions, the importance of a work like this cannot 

 easily be overestimated. The progressive farmer will 

 be greatly helped by a thoughtful perusal of this 

 unique book, which has received the warmest appro- 

 bation of teachers and farmers in all parts of the 

 country. 



The Soil comprises an introduction, which discusses tin- mak- 

 ing of soils by natural agencies; ami chapters follow on the nature, 

 functions, origin and wasting of Boils; texture, composition and 

 kinds of soils; nitrogen of the soil; capillarity, solution, diffusion, 

 and osmosis; soil water: conservation of soil moisture; distribu- 

 tion of roots in the soil; Boil temperature; relations of air to the 

 soil; farm drainage; irrigation; physical effects of tillage and 



fertilizers. 



"I consider it a most desirable addition to our agricultural literature, 

 and a distinct advance over previous treatises on the same subject, not 

 only for popular use, bul also tor Btudents and specialists, who will find 

 many new and useful suggestions therein."
