Plot 1 was at the end of the field where the horses turned in cultiA'titing, and included 

 the head-land made in plowing. This condition in all probability afi'ected the yield on 

 the first plot. Evidently this land needs phosphoric acid more than any other one ele- 

 ment. While phosphoric acid alone may not satisfy the demands of this ground, it 

 suggests the importance of using liberal amounts of this element in preparing fertilizers 

 for this land. Comparing plots 10 and 14, which received the same fertilizers, except 

 that 14 received an application of air-slaked lime, we conclude from this year's work 

 that lime will not prove very beneficial to this soil. It is hoped that a repetition of 

 this experiment may give more beneficial results.
