The six Wealthy trees in plot 2 produced 1168 apples, an 

 average of 98.97 per cent of sound fruit. Individual trees bore 

 from none to 4 wormy apples, yet the percentage variation 

 ranged from 98.79 to 100. 



The above data should be compared with the 58.62 per cent of 

 sound fruit produced by one check Mackintosh tree, and the 

 44.73 psi" cent of worm-free fruit on a check Wealthy tree. The 

 comparisons show a decided advantage accruing from spraying 

 though there is a wide variation in the percentage of sound fruit. 



A summarized tabulation of the results secured from all the 

 plots emphasizes certain important points and is therefore given 

 below. 



Summary of plots 



Summary o£ plots. A study of the entire data shows that con- 

 ditions were fairly comparable in series i and 2, though the yield 

 from the latter was somewhat greater. This larger yield in 

 series 2 is in some measure offset by the trees being larger and 

 more difficult to spray, not only on account of their size but also 

 because of interplanted plum and peach trees. The percentages 

 of sound fruit from the plots in these two series show a fairly uni- 

 form increase with additional sprayings, though in the case of
