cause the rotting of quince fruits had been previously demonstrated 
by experiments made at the Station some fifteen years earlier.‘™ 
In 1887 quince bushes sprayed with a solution of potassium sul- 
phide became severely affected with fire blight, thereby showing the 
inefhiciency of the treatment.’© 
In the third!®* and fourth! reports of the Station the quince 
spot disease,!® which affects both the fruit and leaves, is described 
and illustrated and the interesting statement made that no remedy 
for it is known. A few years later it was shown by the experiments 
of Thaxter at the Connecticut Station'® and by experiments on 
nursery stock at this Station’” that quince spot is very readily con- 
trolled by three to five applications of bordeaux mixture. 
A brief account of powdery mildew?™ of quince leaves is given 
in one of the early reports.1” 
RASPBERRY. 
Anthracnose!” is a common fungus disease of raspberries and 
blackberries. Its most characteristic symptom is the formation of 
discolored spots and blotches on the canes. It is often exceedingly 
destructive to black varieties of raspberries, but does not attack red 
varieties to any great extent. 
Experiments on the control of anthracnose were carried on during 
three successive seasons (1894-1896).1* The principal object of 
the experiments was to determine the value of spraying as a pre- 
ventive of the disease. At first it was thought likely that a very 
early spraying with some strong fungicide would be helpful. Ac- 
cordingly, applications of copper sulphate, iron sulphate and sul-_ 
phuric acid were made before the foliage appeared and this followed 
by several applications of bordeaux mixture. Ultimately, it was 
learned that the early applications were unnecessary; moreover,
