It will be seen by referring to the above tabulation that from 
97.87 to 98.77 per cent of all the fruit, or an average of 98.23 per 
cent was worm free. The end wormy, it will be noted, were ex- 
tremely few, only six occurring upon one tree and two of these 
being side wormy. This very high percentage of sound fruit can 
hardly be attributed to an enormous yield, since it will be noted 
that no tree produced over 2800 apples, while one bore but 873, 
there being no very material variation in the percentage of wormy 
apples between the two. 
The second of these practical tests was in the orchard of Mr Ed- 
ward Van Alstyne at Kinderhook and was restricted to three rather 
small greening trees and two moderate sized Baldwins located in 
the portion of the orchard where we had conducted experimental 
work in earlier years. The trees were selected for the purpose of 
securing as nearly as possible a fair representation of the average 
conditions obtaining, both as to yield and infestation. Mr Van 
Alstyne informs us that the trees were sprayed the last week in 
May, just after the petals had fallen, with 3 pounds of arsenate of 
lead to 50 gallons of water and a lime-sulphur wash testing 25° on 
the Baumé scale and diluted 1 to 25. This spraying was done, as 
was the case of Mr Hart, with no foreknowledge that any practi- 
cal test would be made later. The greenings were picked October 
1oth and the Baldwins October 30th and everything upon the trees 
and under them carefully classified.
