Paris green in the proportion of 1 pound to 250 gallons water. 

 Two applications were made as in the other orchard. In getting 

 data from this orchard, three hundred fruits were taken indis- 

 criminately from all parts of each tree. The percentage of 

 wormy fruits thus obtained, while not absolutely final, may be 

 regarded as a fair basis for comparison. The trees were in 

 parallel rows, thirty feet apart. 



The following figures indicate the comparative results :

As will be seen, more than one-third (34 per cent.), of the 

 fruit on the unsprayed trees was wormy ; while on the sprayed trees, 

 only one-ninth (11.5 per cent.), was wormy. 



In other words, spraying the trees twice with Paris green 

 reduced the number of wormy fruits by 66.3 per cent, and saved 

 more than one-fifth, (22.5 per cent.), of the total crop. 



Results in Mr. Pope's Orchard. 



In order that we might have as many checks on our work as 

 possible, an arrangement was made with Mr. Charles S. Pope, of 

 Manchester, to spray a portion of his orchard with Paris green. 

 But one application was made, June 25, when the fruits were 

 about the size of acorns. 



The results obtained are given in table V.
