continued on the Linden plat after recording the initial stand. The 
data at Bedford were taken throughout the growing season and in- 
clude the harvest results. 
A complete analysis of the field results obtained in this experi- 
ment is given in Table 3. At Bedford the average reduction in 
initial stand due to planting starchy ears was 4.26 per cent. The 
reduction at Linden amounted to 10.21 per cent. The weather con- 
ditions following the planting of this plat were very unfavorable 
for germination. Thus, it appears that starchy ears are especially 
unsatisfactory for seed in districts where weather conditions are 
likely to make it difficult to secure a good stand. As in the earlier 
experiments, the difference in stand was maintained throughout the 
growing season. As the difference between the initial and the final 
stands is made up of losses sustained through blighting, and prin- 
cipally through seedling blight, the results indicate that the suscepti- 
bility of the two groups to such blighting is equal.

Records were taken on the relative vigor of early growth 40 days 
after the date of planting. At this time the plants averaged 24 
inches in height. They were classified arbitrarily as vigorous, semi- 
vigorous, or weak, and records for the entire plat were taken on the 
same day by one person, thus insuring the maintenance of the same 
standard of classification. Rows from the horny seed contained 
larger numbers of strong plants and markedly smaller numbers of 
weak plants than those from starchy ears. These results are in agree- 
ment with the studies reported by Hughes, 4 in which he found that 
horny kernels gave a more rapid early growth than starchy ones. His 
data covered a period of only 20 days, however, at the end of which
