The results of the work can probably be more clearly set forth by 
treating the matter under two heads, namely: 
(1) Result of experiments in Vineyard 1. 
(2) Result of experiments in Vineyard 6. 
(1) RESULT OF EXPERIMENTS IN VINEYARD 1. 
First treatment.—On April 27, when the treatments began, the weather 
was exceedingly dry, no rain having fallen for three weeks. The vines 
were just beginning to grow, the leaves averaging from 1 to 14 inches 
in diameter.
