4 PREFACE. 



the candid opponents of "Book Farming" amongst us to the fact that 

 scientific agriculture consists, not in the indiscriminate practice of Utopian 

 notions, but in working according to the best lights afforded by the 

 combined experience of past ages. And so I wish the forthcoming volume 



God speed! 



Very respectfully yours, 



EUG. W. HILGARD. 



The author is not unmindful of the ordeal through which 

 his work must pass, yet he confidently trusts its merits will, in 

 consequence, the more fully appear, whilst its faults will prove 

 such as rather to stimulate investigation, and thereby improve 

 the general stock of knowledge upon the subject of which it 

 treats. 



Respectfully, etc., 



E. G, WALL, Mississippi.
