Mr. Levison reports all the chestnut trees of Forest Park, 
Brooklyn, to be either dead or dying, and many in Prospect 
Park to be seriously affected. Wherever he has found the chest- 
nut tree in Brooklyn, he has found the disease. 
The natural result must be the death of practically all the chest- 
nut trees in the infected area, unless some exceedingly active enemy 
speedily appears; which is extremely unlikely. Dry summers 
and otherwise unfavorable conditions may delay the progress of 
the disease a few years, but not very long. After the disease has 
run its course and the dead trees have been cleared away, young 
healthy trees, grown from the seed, may be planted with some 
chance of success, especially if carefully cultivated and guarded 
against attacks by aphis and wounds of every description. In 
nearly all the new infections examined I have noticed a dead 
Fic. 28. Inoculation experiments with young chestnut trees. Tree on the right 
killed to the base of the trunk by a body infection; tree on the left reserved as a 
check.
