Concerning the outlook for currants in 1902, it is safe to pre- 
dict that the crop in the Hudson Valley will be somewhat short- 
ened, owing to the premature falling of the leaves last summer; 
but the virulence of anthracnose will probably depend very 
largely upon the nature of the weather next spring The preva- 
lence of the disease in 1901 is certainly favorable to another 
epidemic in 1902, provided the weather conditions are favorable. 
The new wood and fallen leaves are everywhere covered with 
multitudes of the spores ready to start infection again next 
spring if they have a chance. In the Hudson Valley, the spring 
of 1901 was a very wet one as was also the spring of 1889 when 
the other epidemic occurred; so it appears that the disease is 
favored by wet weather. 
TREATMENT. 
If it becomes necessary to fight currant anthracnose resort 
must be had to spraying, which seems to be the only promising 
line of treatment, except, perhaps, the planting of resistant 
varieties. Spraying with the copper compounds, particularly 
Bordeaux mixture, is effective against many fungous diseases 
of foliage and there is little doubt that currant anthracnose may 
be controlled in this way. However, there is but little experi- 
mental data bearing on this point. Prof. Pammel® at the lowa 
Experiment Station, has conducted more experiments on the 
Spraying of currants than any one else in this country and shown 
that Septoria ribis and Cercospora angulata may be controlled by 
spraying with Bordeaux mixture; but Glrosporium ribis was not 
a factor in any of his experiments. Dr. Halsted?? made the fol- 
lowing experiment: “In a row of eight gooseberry bushes, two 
were selected for treatment. Beginning April 25, three appli- 
cations of Bordeaux were made previous to May 22. The bushes 
were again sprayed August 13. The foliage was somewhat 
injured by an anthracnose (Glwosporium ribis Lib.), but there was
