respectively 722.5, 193.6, 149.2, 18.9, 14.1, and 2.9 per cent, 
according to the size of the pot. 
In the above experiment for 1914, the manure was appHed 
on the individual plant basis. Assuming a normal stand of 
3556 hills, each containing 3 plants, an acre of corn has 
10,668 plants. One and seventy-five one hundredths pounds 
of moisture-free manure per plant would be at the rate of 
9.33 tons per acre. 
In 1915, the same six sizes of pots were used as in 1914, 
and contained respectively 36, 83, 161, 253, 561, and 920 
pounds of moisture-free soil. There were eight pots of each 
size, four of which were manured. Table 41 contains a sum- 
mary of the results. Table 42 shows in percentage the effect 
of increasing the pot size upon yield. 
Based upon the yield in the smallest pots, without ma- 
nure, the relative yields of drv matter for the respective sizes 
were 100, 150, 229.6, 355.6, 586, and 578.7 per cent. The 
relative yields of ear corn were respectively 100, 276.2, 819, 
1,647.5, 2,771.3, and 2,667 per cent. 
Table 43 shows in percentage the effects of applying, to 
the pots of different sizes, manure in amounts proportional
