Measurements were not made for the original corn grown directly in connection with these 
pure lines. Therefore the data for the original corn, obtained under similar conditions in com- 
parison with the hybrids between these pure lines and recorded in Table 21, are given here. 
Comparing the averages of the low leaf area pure line 
hybrids with the average high leaf area pure line hybrids, the 
former had 82 per cent as much leaf area per gram dry matter, 
82 per cent as much actual leaf area, 99 per cent as much total 
dry matter, 107 per cent as great ear weight, stalk height 6 
inches taller, and matured 3 days earlier. The same two rather 
distinct ear types prevailed for the two groups that were noted 
for them in 1909, before any inbreeding had taken place. All of 
the plant and ear characters appeared uniform for each hybrid, 
except for some slight variations due to environmental differ- 
ences.
