These comparisons make it evident that in tliis soil potasli was the 

 ingredient most needed. Alone and iu all combinations it produced 

 a profitable increase. The net average increment is sufficient to pro- 

 duce a profit of S2.96 while the result for both nitrogen and phosphoric 

 acid is a loss. The " complete fertilizer" produces a more valuable 

 crop than barnyard manure, and affords a profit, which might have 

 been considerably larger had a part of the nitrate and bone-black 

 been left out. 



Both plaster and lime prove slightly beneficial and their use results 

 in small apparent profit.

*Estimated; part of ears stolen. 



Average of nothings, hard corn, 4.4 bussels ; soft corn, 1.6 bush- 

 els ; stover 550 pounds. 



This experiment was located on the so-called "plain-land" of the 

 Connecticut valley. It is an old alluvial soil consisting of fine sand.
