although the trees bore distinctly lighter crops than plot i, there 

 were relatively more perfect apples, while there was a much higher 

 percentage of scab on the check or unsprayed trees. The vagaries 

 in the leaf roller injury are shown by the fact that the unsprayed 

 trees show less injury of this character than the others. 



Taking the check trees as a standard, it will be noted that the 

 infestation which apparently was very heavy was cut down nearly 

 one-half by the first application and lessened to only a relatively 

 slight extent by the second spraying, though these figures can not be 

 compared strictly, owing to the lighter crop on plot 2 tending to 

 increase, to some extent at least, the percentage of infestation. 

 The increase in end wormy between plots 1 and 2 should be regarded 

 as accidental or attributed in large measure to the small crop on 

 plot 2, and these compared with the very high percentage of end 

 wormy on the check trees, since this latter shows where the major 

 benefit from spraying is secured. There is a marked, though by 

 no means such a great gain in the side wormy. It should be noted 

 that there is comparatively little variation in the percentage of 

 " shallow " affected apples on plots 1, 2 and the checks, indicating 

 that spraying has comparatively little effect, at least the season it 

 is applied, upon this type of injury. 



Miscellaneous Field Notes 



The personal interest of Mr L. F. Strickland, agent of the State 

 Department of Farms and Markets, has resulted in the securing 

 of certain data which are here placed on record. He measured 

 9 apples at the time codling moth deposition began and found a 

 range from if to 2 inches or an average diameter of approximately 

 1 1 inches. The variation in oviposition and the development of the 

 larvae, due in part to the advance of the season and probably also 

 to local conditions, is strikingly shown by the following records. 



In the orchard of Charles Hoag, Gasport, July 26th, 9 entrances 

 and 1 egg shell were found on 104 apples examined in sequence. 

 The trees were well loaded with fruit. 



August 4th, a similar examination in the orchard of Mr G. H. 

 Williams, Newfane, of 56 apples, resulted in finding 49 entrances and 

 8 egg shells; 5 of these apples had 2 entrances each and 2 had 3 

 entrances each. Mr Williams's orchard was practically without a 

 crop and though the counts were male on tress bsaring a fair number 

 of apples, it is possible that there was S3me concentration of the 

 insects upon the fruiting tress, though this hardly, accords with
