The reason for this is found in the fact that the fruit, being 
in piles, barrels or bins, was more or less shut off from a free 
circulation of air, thus allowing the sweating process to progress 
rapidly and vigorously, and the surrounding air quickly became 
moist and warm. These conditions greatly favored the rapid 
development of the disease. 
VARIETIES AFFECTED. 
There was a very inarked difference in the susceptibility of 
different varieties of apples to the disease at the time of harvest, 
and even after they had been in storage for some time. ) 
During the fall Rhode Island Greening, Fall Pippin and 
Fameuse were affected more than any other varieties. Much 
more was heard of the trouble on Rhode Island Greening than 
the other varieties named, but when it is remembered that this 
variety is far more extensively grown in New York State than the 
others and that the crop is more generally barreled and stored 
the reason is apparent. Much damage was done to Tompkins 
King, Maiden Blush and Twenty Ounce. Probably among the 
commercial varieties they would come after the three mentioned 
above. Cases came to our attention where more or less damage 
was done to Gano, Mammoth Black, McIntosh, Rambo, Quebec 
Winter Sweet and Winesap. Among the varieties not as well 
known, Baxter was very bad, and a Russian variety, Safstaholms, 
was completely ruined. 
It was a singular fact that during the harvest time and for 
some weeks afterwards Baldwin and Northern Spy did not show 
any of the disease, although the scab had attacked them fully as 
much as it did the varieties that were badly affected with the rot 
early in the season. For the reason that these two varieties were 
not at all affected at the time the Rhode Island Greening and 
other varieties were decaying, it was generally believed that they 
were immune to the disease, but in December it was found that 
the disease had made its appearance on them. However, it was 
not nearly as vigorous nor as conspicuous as on the other 
varieties.
