158 TWENTY-FIFTH ANNIVERSARY REPORT. 
Bulletin 167,18 A Fruit Disease Survey of the Hudson Valley in 
1899, and Bulletin 191," A Fruit Disease Survey of Western New 
York in 1900, contain notes on a large number of fruit diseases. 
While special attention is given to the distribution and amount of 
damage done by the various diseases other points of interest are 
noted in many cases. The purpose of the Station in making these 
surveys was to secure more accurate information concerning the | 
diseases affecting fruits in the State. Some of the more important 
notes not previously mentioned are: 
In Bulletin £67: Orange rust of blackberry and raspberry; black 
knot of plum and cherry; currant leaf spot; dying of dewberry 
canes; grape root-rot; grape black knot; and strawberry leaf spot. 
In Bulletin 191: Crown gall and hairy root of apple; winter injury 
to apple; collar rot of apricot; yellow fall rust'’? of blackberry ; leaf 
scorch and winter injury of pears; Cytospora canker of plum trees ; 
hail injury to plum trees; gum pockets in plum fruit; and powdery 
mildew on raspberry. 
Both 1899 and 1900 being dry seasons, many diseases were less 
prevalent than usual. One of the most important results of these 
surveys was the discovery of the destructive cane blight of rasp- 
berry and the rediscovery of Fairchild’s cane blight of currant. 
Subsequently, the former disease was given thorough study and the 
latter is under investigation at the present time. 
The voluminous correspondence of the Station brings many in- 
quiries concerning the nature and treatment of the more important 
diseases and insect enemies of plants. In order to meet this 
demand for practical information the Station has prepared three 
special bulletins on the subject, viz.: 
Bulletin 35,1 Some of the Most Common Fungi and Insects, 
with Preventives, published in 1891. 
Bulletin 86° Treatment of Common Diseases and Insects In- 
jurious to Fruits and Vegetables, published in 1895. 
Bulletin 170,1°* Common Diseases and Insects Injurious to Fruits, 
published in 1899. 
Each disease and insect trouble treated in these bulletins is first
