pollen from another cluster, always of the same variety and 
produced under corresponding conditions. Clusters which were 
shaken in the bag containing them, but which were not treated 
with pollen from another cluster, will be referred to as “ close- 
pollinated,” by this term meaning that no other pollen was sup- 
plied to them but that borne in the same cluster. 
The wound made in girdling the cane usually healed readily, 
but occasionally it did not. An extreme case of failure to heal 
is illustrated in Plate XLII, Fig. 1. 
At the close of the season the fruit clusters were rated on the 
basis of 100 points for a perfectly filled cluster. This rating 
was not based upon the size of the fruit as compared with 
normal specimens, but separate notes were made as to size of 
fruit, number of seeds, if any, and other features of interest. 
The results with each variety will now be presented. 
BRIGHTON. 
Brighton is usually self-sterile, but occasionally is slightly 
self-fertile. 
On a girdled Brighton cane 5 clusters were cross-pollinated 
with pollen from other clusters on the same cane. They rated 
60, 50, 60, 0, 0 respectively. Most of the fruits were below 
normal size and seedless. Some had abortive seeds and corre- 
lated with them an increase in size over the seedless fruits. Oc- 
casionally a berry was found of normal size and with normal 
sized seeds. Only one seed in all the lot had a well-developed 
endosperm. Total number of berries, 49. Number of abortive 
seeds, 238. Fig. 2, Plate XLII, shows one of these clusters. 
On another girdled cane eight clusters were close-pollinated. 
These rated 90, 50, 0, 65, 40, 0, 0. All fruits were seedless except 
one, which had three abortive seeds. Total berries, 70. Fig. 3, 
pl. I, shows one of these clusters. 
On a bent cane five clusters were cross-pollinated with pollen 
from other clusters on the same cane. No fruit set. 
On a bent cane nine clusters were close-pollinated. No fruit 
ket. 
On a normal cane 10 clusters were close-pollinated. No fruit
