An examination of the above summary shows that plot 2 pro- 

 duced a light crop and that while there is a progressive increase in 

 the number of perfect apples on the plots sprayed once, twice and 

 three times, there is not for some reason or other an equally good 

 showing in percentage returns. This improvement, as might be 

 expected, is largely due to the more efficient control of scab as a 

 result of the later applications. The figures do not adequately 

 express the true condition of affairs, since many apples counted as 

 scabby on plot 3 showed very much less infection than was the case 

 with plot 2 and even more so of plot 1. The percentage of total 

 wormy fruit for the three plots is about as might be expected after 

 making allowance for the smaller yield of plot 2 and the heavier 

 crop of plot 3, and although the percentage would appear to indi- 

 cate a marked reduction in wormy apples on trees sprayed three 

 times, yet we believe this variation may be explained, in consider- 

 able measure at least, by the larger number of apples. The varia- 

 tion in total wormy, both in number and percentage, corresponds 

 fairly closely with the number and per cent of apples showing the 

 " shallow " type of injury. 



The significance of this summary can best be appreciated by com- 

 paring the data with those obtained from the check tree with its 

 total absence of perfect fruit, its 94 per cent of scabby apples and 

 over 3 1 per cent codling moth infestation. It will be noted that the 

 end-wormy apples on this tree amounted to 5.75 per cent, while 

 on the sprayed plots this percentage was cut down to less than 

 one-fifth of 1 per cent and lower. It is worthy of note that the 

 percentage and relative number of apples showing the " shallow " 

 type of injury on the check trees does not vary greatly from that 

 on plots 1-3, plainly indicating that repeated poison applications 

 are of little value in preventing blemishes of this kind for the season 

 in which the application is made. 



Hilton Orchard 



A series of experimental plots were located June 1st in the Baldwin 

 orchard of Mr Fred W. Curtis, Hilton, N. Y. The trees are about 

 30 years old and stand at an approximate distance of 30 feet from 

 one another. The orchard is somewhat uneven, some trees being 

 missing and, generally speaking, pear trees have been interplanted. 

 The Baldwins were mostly well loaded with blossoms and owing 

 to an occasional missing tree the plots are somewhat irregular. 



The experimental orchard was on the north side of the road east 

 of the barn and the numbering began with the easternmost row
