Report op the Chemist of the 



From this summarized tabular statement, it can be seen that: 



(1) In general terms, the unfertilized land produced the small- 

 est crop; the land receiving 1,000 pounds of fertilizer produced 

 s, considerably larger crop; and the land receiving 2,000 pounds 

 of fertilizer produced a little larger crop than the one receiving 



1.000 pounds. 



(2) The use of 1,000 pounds of fertilizer increased the whole 

 crop 42.1 bushels per acre in 1895 and 34.8 bushels in 1896, the 

 total increase for the two years being 76.9 bushels. 



(3) The use of 2,000 pounds of fertilizer increased the yield 

 over the crop receiving 1,000 pounds of fertilizer to the extent of 



2.1 bushels per acre in 1895 and 11.8 bushels in 1896, the total 

 increase for the two years being 14 bushels for the additional 

 application in 1895 of 1,000 pounds of fertilizer. 



In order to study the effect of the application of fertilizers 

 upon the proportion of marketable potatoes produced, we sum- 

 marize the detailed results given above in the following tabulated 

 statement: 



2. Proportion of Marketable Potatoes. 

 Table Showing Proportion of Marketable Potatoes Produced. 



This tabulated summary indicates that, — 

 • (1) In general, the proportion of marketable potatoes increased 

 with the amount of fertilizer used. 



(2) The use of 1,000 pounds of fertilizer increased the propor- 

 tion of marketable potatoes 6.8 per cent in 1895 and 9 per cent 

 in 1S96, the average increase for the two years being about 8 per 

 cent. 



(3) The use of an additional half ton of fertilizer (or 2,000 

 pounds an acre) increased the percentage of marketable potatoes
