Corn was planted each year, hut the reports fail to 

 account for a crop in 1899. The yields in pounds per acre,

The increased yield, due to the Nitrate of Soda added 

 to plot 4 over 3, which received only phosphoric acid and 

 potash, was 2,596 pounds, a gain of 152 per cent, 



For 1901 the results were 30 pounds corn for the 

 unfertilized plot, 100 pounds for plot 3 and 880 pounds tor 

 plot 4. Plot 18, which received a double application of 

 Nitrate of Soda, gave a yield per acre of 1,640 pounds. 

 The season seems to have been unfavorable for the crop.
