serious lottiiiy and luematiue droppiiij; are apt to occur, and while 

 fifqueul e.\cei)tioiis to this liavc been observed, it is sufficiently constant 

 to su.ii^rest that extensive plantings of it in this region should be made 

 cautiously, if at all, except in the northern portion, where it appears to 

 be more nearly free from serious faults than almost any other commer- 

 cial variety that is being grown, and is considered one of the most 

 )>r()titable sorts. This apjjlies specially to locations in Rap])ahaiinock 

 ("ounty, in close proximity to the mountains. In the Blue Kidge region 

 above an elevation of 1,200 to 1,500 feet premature dropping is gen- 

 erally less severe than it is at lower points. Especially satisfactory re- 

 sults have usually been obtained on Portei's clay at these middle eleva- 

 tions, where very heavy crops are expected, at least in alternate years. 

 If heavy dropping occurs in such cases, a sufficient quantity of fruit

usually remains to result in a heavy ci-op. At the higher altitudes this 

 is considered a valuable variety, especially in North Carolina, where it 

 has grown at 2,500 to 3,500 feet altitude. . . . The contrast between this 

 variety and Winesap in the manner in which they respond to the in- 

 fluence of elevation is of interest. The elevation at which Winesap 

 begins to deteriorate and above which it becomes more inferior as the 

 elevation increases appears to be about the point below which York 

 Imperial is inclined to manifest certain faults which tend to disappear 

 at higlier altitudes.'
