Standard, in grass. This tree 

 seemed to be in fairly good 

 health and sound, but i)ut 

 out rather small leaves and 

 made little "irowtli. It 

 bloomed well, but refused 

 to set fruit even under the 

 stimulus of cross-pollina- 

 tion . 



Standard, in grass. Thougli 

 sound externally, the leaves 

 of this tree were yellowish, 

 as if something were wrong 

 with the roots. It bloomed 

 well, but set no fruit.

 apparently healthy, with

The above work seemingly clemonstrates tliat this variety requires 

 cross-poUiiiatiou by insects iii order to fruit successfully. Aside from 

 a single fruit in the Brockport series (tree No. 12), no self-pollinated 

 fruits were obtained except in the Eochester series. Tire remarkably 

 fine condition of the sx)ecimen trees in Ellwanger & Barry's orchard 

 probably enabled them to set the few self-pollinated fruits found in the 

 bags. These fruits were slightly different iu shape from the crosses, 

 were of excellent quality, and would scarcely attract attention except 

 that they were seedless. It is interesting to notice the difference in 

 fruitfulness between the trees at liocliester and the trees in the Smith 

 orchard at Geneva. This seems almost certainly due to the difference
