CHESTNUT CULTURE—CHESTNUT DISEASES 
Estimate of Varieties 
The varieties of the cultivated chest- 
nuts are not well enough established, nor 
have they been grown on a sufficiently 
comprehensive scale to determine their 
horticultural value. Some of the most 
promising kinds are confined to a few 
trees only. It is therefore impossible, 
to compare the various kinds, justly, but 
the reader would probably not be satis- 
fied unless some expression of prefer- 
ence was recorded. Nothing more than 
a personal preference can be expressed, 
and the following varieties include those 
that the writer would plant on his own 
place for commercial purposes. The first 
list is based upon the behavior of the 
varieties that are growing on an exten- 
Sive scale, the second list includes those 
kinds which are promising, but which 
have not been grown extensively. 
Varieties Grown Extensively 
Japanese—Alpha, Reliance, Parry, 
First choice. 
European — Paragon. First choice. 
Numbo. Second choice. 
Varieties Not in Large Blocks, but 
Promising 
Japanese—Kerr, Kent, Killen. First 
choice. Biddle, Felton, Martin. Second 
choice. 
European—Ridgely, Scott, Styer. First 
choice. Dager, Darlington. Second 
choice. 
The Hale, McFarland, and Coe are high- 
ly spoken of, but the writer has never 
seen specimens and is therefore unable 
to give them a fair estimate.

Anthracnose 
Marsonia ochroleuca B. & C. 
Is a disfiguring spotting of chestnut 
leaves. Small, dead areas with char- 
acteristic borders are produced by this 
fungus. Such applications of fungicides 
as are made for shot hole fungus of the 
plum and leaf spot of the horse chestnut,

Body Blight 
The trunks of the chestnut trees in the 
nursery frequently blight upon the south 
and west sides. The bark splits or sinks 
in and the affected tree finally dies. 
Larger Japanese seedling trees, eight to 
ten years old, are sometimes affected in 
the same manner, but I have not ob- 
served the difficulty on the larger Euro- 
peans. Imported European = seedling 
trees seem to be more susceptible than 
any others, and American seedling stocks 
are affected to a lesser extent. Fig. 1 
shows sections of the trunk affected with 
the body blight. The sections were tak- 
en from trees in a lot of one thousand 
imported European seedlings, nine hun- 
dred and fifty of which died soon after 
setting out. As the malady nearly al- 
ways appears on the south and west sides 
(Japanese varieties are 
trouble.—Ed. )
