“The varieties of apples are more inclined to be sterile to 
their own pollen than the pears. With the former, in the great 
majority of cases, no fruit resulted from self-pollination. The 
results, as w rule, however, were less clear-cut than in the pear, 
because, with most of the self-sterile varieties, an occasional fruit 
will set under self-pollination, and none of the varieties were 
very completely self-fertile.”— Faite.
