New YorK AGRICULTURAL EXPERIMENT STATION. 387 
On normal canes five clusters were cross-pollinated with pol- 
len from other clusters on the same canes. They rated 100, 100, 
100, 98, 100. 
HERCULES, IN 1901. 
In 1901 a Hercules vine trained to the four-arm Kniffen sys- 
tem was treated by having the lower north and upper south 
arms girdled. The upper north and lower south arms were left 
untreated. The clusters were all left open to cross-pollination. 
Hercules is self-sterile, but this vine usually bears fairly well 
because it stands in a mixed vineyard. The total number of 
clusters which developed fruit was 29 on the treated and 16 on 
the untreated canes. The weight of the fruit was 7.6 pounds 
on the treated and 4.6 on the untreated canes. In this case, as 
in the case where Vergennes was girdled and left open to cross- 
pollination, there is an apparent advantage from such treatment. 
The results of the above-described tests are tabulated below.
