CHEMICAL CHANGES IN APPLES DURING STORAGE 



85 



In 1900 the utmost pains were taken to have apples which 

 would be as uniform as possible. They were all picked 

 October 17 from a vigorous Baldwin tree, which had been 

 thoroughly sprayed throughout the season. Unblemished fruit, 

 of as nearly uniform size and color as possible, was selected 

 and put in paper bags, twelve apple in each bag. Two bags 

 containing twenty-four apples were packed in a bushel box 

 with other apples surrounding them, and shipped to the Quincy 

 Market Cold Storage Company, where they were stored under 

 the same conditions as in tlie preceding year. In all, six lots 

 of apples were so prepared and sent to Boston on November 

 18, and one box at a time was returned by express at different 

 dates, the last one being received in September, 1901. The 

 preparation of the sample for analysis was carried out in the 

 manner described for the previous year, and all the analyses 

 were made by Mr. Clark. The first three lots returned were 

 perfect ; the fourth lot, received in July, contained two apples 

 out of the twenty-four, that were slightly decayed, each having 

 a spot about the size of a dime. 



The lot returned in August contained one apple somewhat 

 withered and one partly rotten ; the last lot, returned the first 

 week in vSeptember, had lost one half of its number, four being 

 shriveled a little and eight partly rotten. 



The sound ones only were used for analysis and had reached 

 the stage at which all the cane sugar had become inverted. 

 The keeping qualities of these lots of fruit emphasize the im- 

 portance of careful handling.
