SEVENTEENTH ANNUAL MEETING. 33 



than usual, favors this view, since a very dry reason or dry 

 soil is believed to cause this potato trouble. 



There was received one complaint of spray injury to 

 apples. Since this was different from the ordinary injury 

 of Bordeaux causing russeting of the fruit and spotting' of the 

 foliage, I will mention it here. In this case the trees had been 

 sprayed several times with Bordeaux and lead, the last treat- 

 ment; having been made about the middle of August. The 

 injury consisted of small specks in the skin, especially clus- 

 tered at the bloom and stem ends, in which some of the spray 

 still remained when the fruit was examined in December. 

 The injury was evidently caused by some soluble portion of 

 the spray being finally carried in minute quantities beneath 

 the skin, probably through insect punctures or the lenticals, 

 and causing the death of the cells with which it came in imme- 

 diate contact. 



Last year, at the annual meeting of the Pomological Soci- 

 ety, there was called to our attention the premature, partial 

 ■defoliation of peach trees in certain orchards of the State. 

 During the past season I have had a chance to investigate 

 this trouble more fully, as it was even more prominent then 

 than the year previous. During August I visited an orchard 

 at Seymour where the trouble v/as unusually prominent in 

 certain blocks of trees, and I also examined a few other 

 orchards in different parts of the State where the trouble 

 showed less conspicuously. From all that T could see and 

 learn from the owners, I have come to the conclusion that this 

 trouble results as a_ secondary consequence of winter injury 

 ( most of the trees probably having been injured during the 

 severe winter of 1903-4), made especially prominent the past 

 season by the very severe summer drought. I have not the 

 time to discuss the matter fully at this time, but I wish to 

 make it emphatic as my belief that we do not see all of the 

 serious effects of winter injury the following summer, or that 

 the trouble entirely ends with the cutting out of the dead and 

 Avorst injured trees at that time. Each year, since the severe 

 winters of 1902-3 and 1903-4, has seen trees dying from sec- 

 ondary effects of winter injury, and others have gradually
