was of excellent quality, hut coarser and less delicate in 

 texture and of not quite so good flavor as the apples from 

 West Virginia. The specimens from Oloverland were 

 hard and green and gave evidence of imperfect maturity. 

 Evidently the elevation is too great for its proper devel- 

 opment. The single sample from western Washington 

 consisted of well-colored, extensively blushed fruit, but 

 was inferior in quality. Owing to its limited area of suc- 

 cessful production in the east, it is worth planting in 

 Washington wherever its characters give evidence of a 

 fair degree of balance of adaptation with the environ- 

 ment. This variety is perhaps a better keeper than Wine- 

 sap. Some of the fruit from White Salmon kept in good 

 condition until July, though overgrown fruit and that 

 which has been exposed to heat before storage showed 

 signs of physiological decay late in the season. Under- 

 developed specimens wilted in storage. 



York Imperial. — In sections of Virginia and neighbor- 

 ing states the York Imperial occupies the place of su- 

 premacy held by the Baldwin farther north. This is 

 doubtless due to its perfect balance with the environmental 

 conditions of that region, and, like the Baldwin and other 

 sorts perfectly adapted to their eastern habitat, this 

 variety finds itself out of equilibrium when moved to the 

 northwest. The apples from western Washington were 

 of good size and color, but were coarse and undesirable 

 in texture and poor in quality. The specimens grown 

 at Pullman were smaller, more elongated, and less com- 

 pressed than the others, and the axes were less oblique. 

 They were somewhat better in quality, though not good 

 enough to justify more extensive planting. The fruit 

 wilted in storage, and that from western Washington 

 gave evidence of fungous infection and scalded badly after 

 midwinter.
