CHESTNUT BLIGHT 17 
have introduced Asiatic chestnuts, a large number of which are 
known to have survived the blight in various parts of the country, 
and reports of others are desired. Strains of these oriental chestnuts 
show marked differences in susceptibility, and it may not be practi- 
cable to control the blight on some of the very susceptible ones. 
Ficurp 14.—-A 17-year-old tree of the hairy Chinese chestnut growing at Bell, Md. 
This tree produced over a bushel of sweet nuts of good size in 1928, but only 2 
quarts in 1929 
However, most of the oriental trees can be saved by systematically 
cutting out any cankers that may appear and then painting the 
wounds. If the trees are kept in a vigorously growing condition, 
usually very little cutting out of cankers 1s necessary. Detailed 
information will be supplied by the Office of Forest Pathology, 
United States Department of Agriculture, to anyone interested in 
treating such trees.
