New York AGRICULTURAL EXPERIMENT STATION. 539 
when the blossoms were covered, there can be no doubt that self- 
pollination occurs with all long-stamened varieties. Even with 
short-stamened varieties it cannot be maintained that self-pollina- 
tion is altogether prevented by covering the blossoms by the 
method under consideration; for in these experiments some covered 
clusters of short-stamened varieties have fruited sparingly. Fur- 
ther discussion of pollination of the grape is reserved for a future 
report. 
ENVIRONMENT MAY MODIFY SELF-FERTILITY. 
The influence of environment on the self-fertility of the grape 
has not received the attention which it deserves. In order to se- 
cure some data on this subject varieties which had previously been 
tested at the Station were tested again in other localities, 20 of 
them in the vineyard of Mr. E. C. Gillett, Penn Yan, N. Y., and 
15 in the vineyards of Mr. George C. Snow, near Branchport, 
N. Y. Much credit is due these gentlemen for courtesies extended 
to the Station and for their cordial cooperation in the work. 
Four of the varieties were tested in both these places and at the 
Station so that tests with them were made in 3 localities the same 
season. Eleven varieties were tested in 2 different localities simul- 
taneously. The results of the tests in the different localities are 
presented briefly in the following tabulation:
