each tree. The percentage of wormy fruits, while not absolutely 

 final, may be regarded as a fair basis for conpirison. The trees 

 were in parallel rows, thirty feet apart. 



TABLE II. 



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

 the unsprayed trees was wormy, while only one-ninth (11.5 per 

 cent) was wormy on the sprayed trees. In other words, spraying 

 the trees twice with Paris green saved more than one-fifth (22.5 

 per cent) of the crop. It had been our purpose to spray some of 

 the trees three times, but as the land was in the meadow, the third 

 application was omitted. 



From a consideration of the trees already mentioned, and also of 

 a number of Baldwin trees from which all of the windfalls were 

 gathered and counted, we conclude that the average percentage of 

 fallen fruit from the unsprayed trees is nearly double that from the 

 sprayed trees. With the Hubbardston, the difference was even 

 more marked. (See table I ) 



In order that we might have as manj^ checks on our work as 

 possible, Mr. Charles S. Pope of Manchester, undertook to spray a 

 portion of his orchard with Paris green. One application only, was 

 made June 25th, when the fruits were about the size of acorns. 



Table III indicates the results obtained.
