which were previously infected, the disease seems to have made 

 comparatively little headway during the past season. Even at 

 the locality in Alford which was reported as the worst seen in 

 the State last year, and which still maintains that reputation, no 

 new trees seemed to have died, and the disease had increased but 

 little. A few new lesions were observed in some places through- 

 out the county, principally on small twigs, including one appar- 

 ently on the new growth of the year. 



A former employee of the Pennsylvania Blight Commission 

 says that the infection in this region is more general than he has 

 seen it even in eastern Pennsylvania and New Jersey. In these 

 States the diseased trees occur in more or less widely separated 

 groups, while here they are commonly uniformly distributed 

 throughout the stand. 



In Wilbraham and Hampden, Hampden County, the disease is 

 as widely distributed as in Berkshire County, and the increase 

 for 1912 is apparently no greater. On one tract of sprout growth 

 observed by Mr. Robert I. Edson, forest warden of Wilbraham, 

 on which every tree is attacked, the disease has made very little 

 headway the past year. Mr. Edson is the man who first called 

 the attention of this office to the presence of the disease in Massa- 

 ■ chusetts. 



Lumbermen in Hampshire County say that the disease has 

 made a great spread there. It seems probable, however, that 

 this is due rather to better recognition of the disease than to an 

 actual increase. 



In southeastern Worcester County very little fresh work was 

 seen. In particular, one of the group of sprouts in the town of 

 Douglas, photographed in January, 1912, which at that time had 

 a fair-sized canker on the trunk, was on October 3 still green in 

 the top. The canker was larger but had not spread completely 

 around the trunk, although this was only four inches in diameter. 

 The larger tree, photographed the same day, had lost only one 

 additional branch. 



All over the State, with the possible exception of Hampshire 

 County, as noted above, the disease seems to have made much 

 less headway than was to have been expected from its previous 

 rate of spread. 



It is reported that experimental inoculations in Pennsylvania
