The lectures of the autumn course will be delivered in the

December. They will be illustrated by lantern slides and other- 
wise. The program will be announced on a special card. The

Central Railway to Bronx Park Station, or by the Third Avenue 
Elevated Railway to Bronx Park. Lectures will close in time

FURTHER REMARKS ON A SERIOUS CHESTNUT 
DISEASE. 
A preliminary account of this disease appeared in the June 
number of the JournaL. At the time the account was written 
the disease was just beginning to spread on the twigs and 
branches from the infected areas in which it had spent the 
winter, On my return to New York in August, I found it very 
abundant and very destructive, the warm, moist summer having 
been exceedingly favorable to its development. Hardly a tree 
in the Garden had escaped infection and many dying and recently- 
killed branches were observed. I now know of very few chest- 
nut trees in this portion of the city that appear to be worth trying 
to save and I do not consider any immune.
