Experiment 5, in the orchard of Frank Chaplin, Gasport. This 

 is an orchard of about twelve acres, mostly Baldwin, set twenty 

 years ago. It was in sod till 1895; since then it has received 

 clean tillage. The trees are of medium size, thrifty, moderately 

 productive in past years. Mr, Chaplin sprayed in 1899 with Bor-

 materials. He is a very thorough sprayer. Sixteen Baldwin 

 trees were selected, all very evea in size and full of bloom. (1) 

 Four were sprayed May 16, when a very few blossoms were 

 partly open. Weather slightly showery in the morning, clearing
