16 NEW YORK STATE MUSEUM 
produced only 1366 and 1159 apples, respectively, the others ap- 
proximating 3000. The variation in percentage of sound fruit is 
not great and the average for the entire plot is excellent. It will be 
noted that a very large proportion of the wormy fruit, namely 291 
out of the total 305, were side wormy, only 30 being end wormy 
and more than half of this latter number, namely 16, being both 
end and side wormy. 
Plot 2 comprised seven small Ben Davis trees located in a lot 
north of the house next to the woods and west of a small creek. 
These trees are 15 to 16 years old, 10 to 17 feet high and about 30 
feet apart. The check tree was in the southeastern portion of the 
plot, next the small creek and in a position where thorough spray- 
ing was not easy. The wind continued high and about five gallons 
of spray were used for each tree, the treatment being continued 
until there was considerable dripping. The spraying was followed 
by a heavy shower in the afternoon and rain during the night. This 
plot was moderately well laden with fruit, and our subsequent data 
show that there was a fairly uniform yield, except possibly in the 
Case of tae check tree. 
An examination of this plot on August 16th showed there had 
been some spotting of the foliage by the work of a Hemipteron. 
It was estimated at that time that the check tree would produce 
50 per cent of wormy apples and there was observed in this tree an 
apple tent caterpillar’s nest, something not seen upon those which 
had been sprayed. There was nothing particularly significant about 
the trees at the time the fruit was picked on October 14th. It is 
barely possible that the tree selected as a check was not entirely 
representative, since its position was such that the spraying of the 
previous year could hardly have been as thorough as in the case of 
the other trees. There is also a possibility that certain wormy ap- 
ples may have been swept down the stream from trees above. We 
believe both of these factors are comparatively insignificant, though 
they may have had an influence upon the yield. The tabulation of 
the data secured from this plot and the check tree is given on the 
following page.
