THE RESULTS. 



In studying the yields of the several fields it is well to bear in 

 mind that Field A was used continuously duriug the seven years for 

 cotton and corn, except in 1908, when oats without fertilizer were 

 grown in the spring and followed by a crop of fertilizer experiment 

 peas in the summer. Field B was used continuously for corn and 

 cotton, but had oats and peas in 1909. Field C grew oats and peas, 

 oats without fertilizer and peas in the regular fertilizer experiments 

 in 1904-5-G-7; cotton in 1908, and corn in 1909. 



In the future, as during the past three years, the crops will be 

 grown according to the following rotation:
