The fruits which developed to normal size were supplied with 
a little less than the usual number of seeds. One hundred Hop- 
kins fruits from clusters open to cross-pollination averaged 4.05 
seeds per berry; those of Hopkins x Ozark averaged 3.01, and 
Hopkins x Hexamer 3.03 seeds per berry. The single fruit of 
Bailey x Black Eagle had 3 seeds. 
In order that the results of the tests which are shown on the 
preceding pages may be compared with those obtained in using 
the pollen of self-fertile varieties upon other self-sterile varieties, 
the following table of Bulletin No. 169 is reprinted here. ‘The 
data given in that bulletin are here arranged with reference to 
the ability of each variety to fertilize itself as compared with 
its ability to fertilize the various self-sterile sorts upon which 
it was tried. 
Explanation of table-— The x between two names indicates that 
the variety following the x was used in pollifating the variety 
-whose name appears before the x. Thus, Brighton x Aminia 
indicates that the Brighton clusters were pollinated with 
Aminia pollen in the manner described on page 335 of Bulletin 
No. 169. The rating is on the scale of 100 points, as there ex- 
plained, a perfectly formed and perfectly filled cluster ranking 
100. The average rating and the number of tested clusters upon
