1. Self-pollinated Newtown apples, producing at least one-third of the apples undersized. 2, Newtown 
apples pollinated by Grimes Golden; no small apples.— (After Lewis and Vincent.) 
ing, Tolman Sweet, Wealthy, and Wine- 
sap; among the self-fertile were Baldwin, 
Oldenburg, Shiawassee, Washington, and 
Yellow Newton; partially self-fertile were 
Ben Davis, Stark, Spitzenburg, and Yel¬ 
low Transparent. The experiments showed 
that in the majority of cases cross-pollina¬ 
tion is a necessity to ensure a profitable 
crop. Crossing always gave better results 
than self-pollination, and is the rule, while 
self-pollination is the exception. Cross- 
pollinated trees gave larger and finer fruit 
with well-developed seeds; while self- 
pollinated trees gave smaller fruit with 
the seed usually wanting or abortive, as is 
shown in the following table:
