varied distributions was 73.0 bushels compared with 74.3 bushels 
for the uniform planting rate of 3 plants per hill. A uniform 
stand of 3 plants per hill yielded 1.8 per cent more than the 
mean for the various distributions. Variations in stand due to 
the planter, or to the presence of dead seed in corn testing as 
low as 75 per cent, is less marked than the variations in the 
above special plantings. 
The data in Table 34 are substantiated bv a very similar 
experiment conducted by Montgomery in 1907 and 1908, the 
results of which are given in Table 35. The average yield of the 
varied distributions in this test was 2.1 per cent lower than a 
uniform distribution of three kernels.

EFFECT OF IMPERFECT HILLS IN CHECKED CORN 
The data in Tables 36 and 37 show how the crop adjusts 
itself for missing plants in an otherwise uniform stand. Dur- 
ing the two years, 1914 and 1917. a rather large number of 
corn hills containing either 1, 2, 3 or no corn plants were 
scattered systematically thruout a field of checked corn other- 
wise containing 3 plants per hill. By harvesting the hills 
separately, the effect of hills containing 1, 2, or no plants upon 
hills with the normal number of 3 plants could be determined. 
Also the relative yields of hills containing 1, 2. or 3 plants when 
surrounded uniformly by 3-plant hills could be determined.
