In the orchard of Mr. F. D. Grardner, Barker, N, Y., several 

 varieties were sprayed in bloom. These trees have been planted 

 27 years and are from 15 ft. to 20 ft. high. They stand 34 ft. 

 apart. They were treated as stated below: 



Sprayed all alike before blossoms opened. 

 r Sprayed Tompkins King and Twenty Ounce in Rows 5 

 I, and 7. These were then in full bloom. 



Sprayed Roxbury Russet and Rhode Island Greening in 

 Row 5 which were then in full bloom^ 

 Just after blossoms had fallen, sprayed Tompkins King 





in Row 8 and Twenty Ounce in Row 9. 



The accompanying plan shows the relative position of the trees 

 under experiment.

In all treatments Bordeaux mixture, made by using one pound 

 of copper sulphate for Q-l gallons, and Paris green at the rate of 

 1 lb. to 133|- gallons, were used. The Twenty Ounce and 

 Tompkins Kin g came into bloom earlier and so were sprayed iu 

 bloom several days before the Roxbury Russet and Rhode Island 

 Grreening were so treated. The treatment was made very 

 thoroughly. little air was stirring and it was possible to spray 

 and do excellent work from either side of the tree. But even 

 with most thorough Jjeatment some of the open blossoms were
