As has beensuggested in other connections, the apparent retarding in the ripeningprocess may have been due to the greater susceptibility to decay ofthe ripest apples, and consequently to an increase in the percentage ofthe relatively greener apples on each successive examination. THE RESPIRATION OF APPLES IX COMMON AND COLD STORAGE. On October 20, 1902, a barrel of Ben Davis apples, grown at SouthOnondaga. N. Y., was secured for respiration experiments. Description of Apparatus and Methods Employed. Three stone jars of the form shown in figure 11 were secured ascontainers. These jars were the ordinary glazed stoneware chlorin. Fig. n.— Jar used in respiration experiments. generators with stoneware covers having a ground joint. A- shown inthe illustration, the jars were arranged to afford the passageof a slightcurrent of air. A guard tube of soda lime, then a drying tube of cal-cium chlorid, and then a Lube of moist pumice stone were connected inseries before the apparatus. The last-named tube was for the purposeof moistening the air which passed through the apparatus, as the pas-sage of a dry current of aii- would desiccate the apples and cause themto shrink abnormally. Tl e tube of calcium chlorid just before thepumice stone was used in order that by repeated weighings of the latterthe amount of water carried over into the jar with the current of airmight I). determined. Connected in series after the generator were STORAGE, RESPIRATION, AND GROWTH. 41 t
