The results set forth in Table II show that the pollen of the 
self-sterile varieties therein named is either deficient in amount 
or lacking in potency, or both. Table IV bears similar testi- 
mony on this point. The results given in Table III show that 
some varieties which are nearly or quite self-sterile may to some 
extent fertilize certain other varieties. Occasional indications 
of this fact are also seen in Tables II and IV. The questions, 
however, are still not satisfactorily answered as to whether the 
self-sterility under investigation arises because the pollen is 
uncongenial to its own pistil, or because it is deficient in amount, 
or because it is nearly or quite impotent either upon its own or 
upon other pistils. The last-named condition seems to hold 
with Black Eagle pollen, because, as shown in Table III, even 
when it is supplied in abundance it fails to effect the fertilization 

_ § But one cluster produced fruit and that was gathered by grape pickers before it had been 
rated. Its rating was somewhere between 80 and 100, making the average between 6.1 and 7.7. -
