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 

 ISO© the smallest yield on any treated plat (456 lbs.) was 38 per 

 ct. larger than the largest yield on any untreated plat. (330 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 plate and covering all three 

 years, was 9,666 pounds or 64 barrels per acre. However, a brief 

 •tudy of the table is sufficient to show that this amount is surely 

 imaller than the true measure of the benefit derived from the 

 treatment. This is true because of the abnormally small yield in 

 189'8. In that year the crop was injured at least 50 per ct. by 

 hail and there was also considerable loss from rot. Leaving the 

 ■eason of 1898 out of consideration, the average annual increase 

 per acre due to the treatment was 13,492 pounds or 90 barrels.
