THE DECAY OF APPLES

The covers of the boxes were made of slats with spaces between 

 so that there was ample chance for the circulation of air. The 

 boxes were withdrawn from cold storage, one each month, until 

 June, when they were withdrawn two per month until the 

 twelve had been exhausted. On receipt of the boxes the apples 

 were examined and the number of sound and rotten ones 

 counted. The sound ones were stored in the station's cold 

 storage room. A similar box for comparison had been kept 

 here from November i8. The following table shows the 

 results. Throughout the tables apples not perfectly sound are 

 rated as rotten. 



TABLE I. 



The temperature at which the apples were kept in the Bos- 

 ton cold storage was about 34° F. In the station cold storage 



*In case of Box No. 2, the wrapped apples were not opened when the box 

 was first received. The percentage of sound ones is assumed to have been 

 the same as in the unwrapped. The notes on No. 3 have been lost or mislaid. 

 The percentages given are reckoned from the number in the box at the 

 second examination, which were the sound ones when first received.
