the Berkshires. Along the Hudson River the chestnut is plentiful, but 
not so abundant as in the hills. It was along the state line, in these heavy 
stands of chestnut, that the disease had made the greatest ravages. It 
was present, however, in every locality where there was any quantity 
of chestnut. Practically every town east of the Hudson River is repre- 
sented in the list of those in which the disease was found. In those towns 
in this region from which the disease was not reported, the stand of chest- 
nut was slight. In the central part of Rensselaer county there is little 
chestnut, and especially is this true of the part near the Hudson River. 
Along the state line separating New York from Massachusetts and Ver- 
mont, in the continuation of the Berkshires northward, there is considerable 
chestnut, but no disease was found there. 
The natural northern limit of the chestnut, as is seen by the map, 
is in the towns of Fort Ann and Granville, in Washington county. The 
disease was found very abundant throughout Washington county. Many 
lumbermen were cutting chestnut as rapidly as possible in the towns 
of Hartford, Argyle, and Hebron, in order to keep ahead of the disease. 
West of the Hudson River the disease had not advanced so far north. 
Practically the entire stand of chestnut in Orange county and in southern 
Ulster county was diseased. In the Catskill Mountains proper there is 
much chestnut in the valleys opening into the Hudson River Valley. 
In the southernmost of these valleys the disease had spread as far as chestnut 
is to be found, but in the Esopus Valley and in the valleys north of it the 
disease had spread for only a little distance. In Albany county the 
chestnut is scattering, except in the Helderberg Mountains, and it is very 
scarce in the western part of the county. A complete survey of Albany 
county was not made, owing to the unimportance of this information; 
however, the disease was found general in the southern part of the county 
along the Hudson River. 
The connecting link between the chestnut region of the Hudson River 
Valley and that of the central and western part of the State is the strip 
in Sullivan county along the Delaware River. Chestnut is abundant 
here for fifteen to twenty miles away from the river. Many isolated 
spot infections were found here. The general spread extended about 
as ‘far up the Delaware River as Port Jervis. A few spot infections were 
found in southern Delaware county along the Delaware and Susquehanna 
rivers. One spot infection was found at Masonville, Delaware county, 
and was destroyed. No infections were known west of this region in 
tg11. A special investigation of the cause of the dying of the chestnut 
near Cooperstown was made, but it was found not to be due to the 
canker disease.
