third bushe! of badly infested Baldwins was placed in the center of 
each of the barrels and carefully repacked. The slat bottom used 
consisted of several strips of wood fastened so as to replace the lower 
head and hold the fruit in place. In No. 26 the upper barrel head 
was also removed, leaving the fruit fully exposed above and below,

in the box, the gas could pass through the barrel, thoroughly sur- 
rounding the fruit. The treatment of barrel in No. 27 differed only

only. Two examinations of the Baldwin apples from center of 
barrels were made at intervals of two weeks. In the first, Novem-
