Regarding, first, the sulphured hops, the data m Table II show 
that the percentage of soft resins decreased somewhat during the 
first and second years of storage and very rapidly during the third 
year. ‘The decrease was less, however, in the cold-storage samples 
than in those kept in open storage. The unsulphured hops show a 
marked decrease from year to year, the decrease being most pro- 
nounced in the third year of storage. The unsulphured samples in 
open storage show a greater loss than the corresponding samples 
kept in cold storage. 
During the first year 
of open storage the 
soft-resin content in 
the sulphured hops 
decreased less rap- 
idly than in the un- 
sulphured hops, but 
more rapidly in the 
following two years. 
It will be observed 
from figure 1 that 
the quantity of soft 
resins present in the 
sulphured hops in 
both cold and open 
storage decreased 
during each year and 
that the decrease was 
especially marked 
during the third year 
of storage. Figure 1 
also shows that the unsulphured hops in cold storage decreased in 
soft-resin content more rapidly than the sulphured hops and that 
this decrease was rapid during the first year, less pronounced during 
the second year, and at the end of the third year gradually ap- 
proached the same point of value as in the sulphured hops in cold 
storage. The soft-resin content of the unsulphured hops in open 
storage decreased at about the same rate as that of the sulphured 
hops in open storage. 
The percentage of decrease in soft resins during the three years, 
as compared with the original samples, is given in Table III.
