STORAGE OF APPLES IN THE PACIFIC NORTHWEST. 23 
Rome Beauty stored at 32° and 35° F. Noticeable differences in 
appearance and texture were apparent in nearly all lots at this time, 
however. At the third and fourth withdrawals of these varieties 
the fruit stored at 35° showed considerably more decay than that 
stored at 32° F. In other words, fairly good keeping varieties may 
be held for some time at a temperature of 35° F. with practically as 
good results as far as loss from decay is concerned as if the fruit 
had been held at a lower temperature. As these varieties approach _ 
the end of their storage periods, however, the effect of the higher 
temperature is manifest, and the failure properly to retard the life 
activities of the fruit results in its premature death and decay. This 
is especially noticeable during the holding period after the fruit has 
been withdrawn from storage. The apples stored at 32° F. had 
enough reserve vitality to hold in good condition during this period, 
but the more advanced 35° F. fruit went down with comparative 
rapidity. 
In Esopus (Spitzenberg) striking results are noted at the first 
two withdrawals and inspections. As the storage life of this va- 
riety is naturally shorter than that of Winesap and Rome Beauty, 
results of this kind are to be expected. Storage at 35° F. has mate- 
rially shortened the holding period of the lots so treated, and this 
influence is manifested very early in the storage season. 
The most favorable storage temperature, however, can not prevent 
the final, natural death of the fruit, and at the third and fourth with- 
drawals of Esopus (Spitzenberg) both lots are past the limit of suc- 
cessful storage, although the lots from 32° F. are still superior to 
those which have been stored at 35° F. 
COMMON STORAGE. 
During the seasons of 1912-13, 1913-14, and 1914-15 a limited num- 
ber of boxes of apples were stored in well-constructed common stor- 
age houses at Hood River, Oreg., and at Payette, Idaho, while com- 
parable lots were held in cold storage at 82° F. As the data obtained 
were limited, no attempt will be made to present them or to discuss 
the result in detail until corroborated by further investigation. 
As might be expected, however, they indicate that a common stor- 
age house cooled by natural circulation only can not take the place 
of a cold-storage warehouse for long keeping.of the fruit. This 
statement does not in any way belittle the value and utility of com- 
mon storage houses, as they will always play an important part in 
the harvesting and storage of the apple crop. The fact that a house 
of this type can be constructed at the orchard or in conjunction with 
the local packing house with a much smaller outlay of capital than 
is required for the construction of a cold-storage warehouse is a
