gm. loss from each set of wrappers. This loss can be fully accounted 
for, as explained above, in passage of oil to the liners. There was no 
indication of oil on the apples, and if any passed over to them in either 
set of experiments it must have been the merest trace.

EFFECT OF OIEED WRAPPERS ON UNWRAPPED FRUIT OF THE SAME PACKAGE 
In a number of experiments only a part of the apples of the package 
were in oiled wrappers, the others being held either unwrapped or in 
unoiled wrappers. Table VI shows the scald control secured under 
these conditions. The eastern apples were packed in barrels with part 
of the apples unwrapped and the northwestern ones in boxes with part 
of the apples in oiled wrappers and part in unoiled ones.
