in the same year as in plats sown on the same date in the different 
years. The lowest, 60.7 per cent, in the 5-year period was from the 
seeding made June 1, 1918, and the highest, 97.5 per cent, was from 
the seeding made on May 24, 1917. In the former case it will be 
noted in Table II, which shows the daily and monthly precipitation, 
that the crop was grown under very dry conditions. In the latter, 
the month of August, at which time the crop was heading, was 
quite favorable. | | 
The average height of the plants in the different years ranges 
from 3.5 to 6.3 feet. The height depends largely upon the rapidity 
of growth during the first 30 or 40 days of the vegetative period. 
When the height of 6.3 feet resulted from the seeding made June 19, 
1915, the soil was in a moist condition and remained so for some 
time, with a temperature favorable for rapid growth. At other 
times during several of the years when the plants reached a height 
of less than 4 feet, the crop encountered a long droughty spell during 
the vegetative period.
