DISEASES OF APPLES ON THE MARKET. 
21 
For example, York Imperial and -Rhode Island Greening in the barrel 
crop are known to be much more susceptible to scald than is Wine- 
sap. Yet because of this known susceptibility they are usually 
marketed early (to avoid scald) and so appear in the table as actually 
less susceptible than Winesap. The same seeming contradiction can 
be noted in several other instances in both the barrel and the box

to sell. Furthermore, inspection is frequently asked for on cars 
that are not moved until much later.
