FELT: CODLING MOTH 



157 



equal number of plots in each year. Reference to earlier published 

 data shows that the low percentages occurred in 1910, a season remark- 

 able for the unusual abundance of the second brood and one presenting 

 infrequent conditions which were greatly accentuated by the small 

 yield of the experimental trees. Excluding the data for this year, 

 the lowest average percentage of sound fruit for one plot was 97.52. 

 Incidentally, it may be well to note that less than h of 1% (.394%) 

 of the wormy fruit from trees sprayed but once were end wormy.
