it was about 40° until April, when it rose to 45° during the 

 first half of the month and to nearly 50° during the latter half. 



No satisfactory explanation of the lack of uniformity in the 

 increase of the percentage of rotten ones with length of time 

 of storage can be offered. 



The indications from the percentages in case of boxes 5, 6, 

 7, and check box, are that the conditions were more favorable 

 to keeping in the Boston cold storage than in that of the sta- 

 tion. 



On June i only 5 per cent, of the check box apples were 

 still sound, as against more than 50 per cent, in case of those 

 still at Boston. 



The following table shows the percentages of sound apples 

 in wrapped and unwrapped lots, with difference : 



TABLE II. 



These figures, except in 4 and 8, are in favor of the wrapped 

 ones. Later examinations of the first five boxes which were 

 kept in the station cold storage after their return showed the 

 same result. 



April 20 a comparison of the first four boxes with the check 

 indicated that they had not kept as well since their return as 

 those stored at home ; but May 29 a larger percentage of those 

 that had been in the Boston storage were sound than in case 

 of the check. 



Series II. The Baldwins used were gathered mostly dur- 

 ing the latter half of October. They were stored for a short 

 time in the barn and were then packed in bushel market boxes 

 as in wSeries I, special care being taken to secure uniformity in 

 their contents. About half of the apples in each box were 

 unwrapped and the other half wrapped. Four different forms 

 of wrapping material were used, viz., heavy w^axed manilla
