over was not confined to the fruit basin or restricted to that 

 part of the apple. The sides of the fruit were Hkewise affected 

 and frequently deep clefts in the flesh occurred in conjunction 

 with the burned skin. The injury when confined to the basin 

 resulted in many cases in a marked shrinking and depression 

 of that part. In addition, the fruit was stunted in growth and 

 frequently misshapen. In color, texture and general characters 

 the injury on these apples corresponded to that of calyx injury. 

 It was, as may be seen, (Figs. 53 and 54) greater, and it also 

 extended deeper into the sub-cuticular tissues. Rot of injured 

 fruit at harvest was also greater on fruit from this plot. 



In examining the fruit of the unsprayed plots we find evi- 

 dence that must largely modify the conclusions to be drawn 

 from this year's results. Fruit removed as completely as pos- 

 sible from the liability of catching spray from the Other plots 

 showed injury of the kind illustrated (Fig. 55). Aside from 

 this, fruit not deformed showed a considerable amount of rus- 

 seting, also of varying degree. 



A comparison of fruit from the several plots as to general 

 appearance was notably in favor of all the lime-sulphur sprays. 

 The apples from such plots were larger, of better color and had 

 an attractive waxy bloom. In this respect f 1 ait from Plots 

 5, 6, 8 and 9 was especially noteworthy. 



The "Sulfocide" plot produced smaller apples but on the 

 average of still higher color. The fruit from the bordeaux 

 plots was decidedly inferior in finish and color to any of the 

 rest. 



Effectiveness in Fungous Control. 



The early part of the season was favorable for infection by 

 scab and fruit spot (Cylindrosporiiim Pomi, Brooks), as indi- 

 cated by the check plots and unsprayed trees in the vicinity of 

 the orchards. A prolonged drought in June and July doubtless 

 served as a check on late infections. 



The leaves on the unsprayed trees were nevertheless consid- 

 erably afifected by scab, infection being estimated at 70 per cent, 

 of which 50 per cent was severe. 



The self-boiled lime-sulphur showed least fungous control of 

 any spray used. Here the per cent of foliage infection was
