New York AGRICULTURAL EXPERIMENT STATION. 547 
In the following classification the varieties are arranged in four 
classes according to the average character of the clusters which 
have developed from covered blossoms on vines in apparently nor- 
mal condition. In cases where there is doubt as to whether the 
vine was in proper condition for the test the name is followed by 
a question mark to indicate that the classification is doubtful. 
Class 1 includes varieties which when self-fertilized have formed 
none but perfect clusters and those with which the clusters have 
varied from perfect to somewhat loose. 
Class 2 includes varieties which when self-fertilized have on the 
average formed marketable, although not compact clusters. 
Class 3 includes varieties which when self-fertilized have on the 
average produced clusters too loose to be marketable. This class 
has a wide range. It extends from the varieties in Class 2 with 
clusters not too loose to be marketable, to Class 4 which includes 
the self-sterile sorts. There are varieties in this class which have 
on the average produced self-fertilized clusters nearly compact 
enough to be marketable, some being rather compact, but others 
being loose. At the lower limits of the class are found varieties 
which usually fail to produce fruit on covered clusters but 
which occasionally have borne a few scattering fruits when the 
clusters were covered. 
Class 4 includes those varieties which have not produced any 
fruit on covered clusters.
