Discussion of results—From an examination of the table above 
it will be seen that every treated plat yielded more than the 
adjacent untreated plat, and this was true for all three years. In 
1899 the smallest yield on any treated plat (456 lbs.) was 38 per 
ct. larger than the largest yield on any untreated plat. (3830 lbs.) 
Moreover, this increase in yield was not a trifling one. It varied 
from 814 pounds to 23,384 pounds per acre, and the average 
increase in yield, including all the plats and covering all three. 
years, was 9,666 pounds or 64 barrels per acre. However, a brief 
study of the table is sufficient to show that this amount is surely 
smaller than the true measure of the benefit derived from the 
treatment. This is true because of the abnormally small yield in 
1898. In that year the crop was injured at least 50 per ct. by 
hail and there was also considerable loss from rot. Leaving the 
season of 1898 out of consideration, the average annual increase 
per acre due to the treatment was 18,492 pounds or 90 barrels.
