REPORT OF CRANBERRY SUBSTATION FOR 1915.

from increased decay as compared with the surface berries. With the 

 berries at the center of the box, however, the increase in incipient and 

 advanced decay, in comparison with that of the other berries, was evidently 

 sufficient to cause a shrinkage which the reduction in the loss of water could 

 only partly offset. 



2. Two lots, one consisting of 64 bushels (16 stacks of 4 boxes each) 

 of Early Black berries, and the other of 36 bushels (9 stacks of 4 boxes 

 each) of Late Howe berries, were stored as were the berries in the first 

 series of tests. The Early Black berries were picked on different dates 

 between the 13th and 22d of September, and the Late Howe between the 

 12th and 22d of October. The berries of both lots were examined during 

 the first week in January in the same way as were those in the first series. 

 The averages of the totals of the four counts obtained in the examination 

 of the samples of the four boxes of each stack are given in the following 

 table : —

 Decay. — Results of Second Series of Storage Tests. 



For an explanation of the lettering in the table indicating the different 

 parts of the box examined, see the description of the "five-sample" 

 method given above in the discussion of the first series of tests. As the 

 figures of the table show, the results of this series of tests were entirely 

 similar to those of the first series. 



3. Thirty-nine boxes (bushel picking crates with slatted bottoms and 

 sides), some with Early Black and some with Late Howe berries. This 

 fruit was stored like that in the first two series of tests. It was picked on
