one feel fully at home. A series of photographs was secured 
during the second visit, and these used in illustrating a lecture 
given by the writer at the New York Botanical Garden on 
October 31, 1908, an illustrated account of which appeared in 
this JouRNAL for November of the same year. For a detailed 
account of the establishment of Letchworth Park and of the 
writer’s impressions of this wonderfully beautiful and picturesque 
region, the reader is referred to that article.

THE CHESTNUT CANKER CONVENTION. 
A convention called by Governor Tener to consider ways and 
Pennsylvania, February 20 and 21. A large number of delegates 
were present, representing practically all of the states where the 
chestnut tree grows naturally in this country, and the papers 
and discussions brought out much valuable information. 
The method of control adopted by the Pennsylvania Commis- 
sion is that outlined in Farmers Bulletin 467 of the United States 
Department of Agriculture, which recommends the cutting out 
of infected trees and the establishment of an immune zone. 
Several pathologists present endeavored to show that this 
method has not been sufficiently tested, and that the only 
proper way in which appropriations may be spent is in the 
scientific investigation of the disease with the hope that some 
effective method of control may yet be discovered, and in aiding 
state surveys to locate the disease for the information of timber 
owners. The resolutions adopted by the convention, however, 
favored a campaign in all of the states affected similar to that 
already begun in Pennsylvania, which combines scientific investi- 
gation and the cutting out method. 
It seems to the writer that the only proper procedure for the 
other states is to make surveys, with the aid of small appropri- 
ations if necessary, and to await the results of the scientific
