On examination of the figures in table i, it is evident that no greater 
difference is to be found between the keeping quality of dry- and water- 
raked berries than may be found between certain lots picked by the same 
method. This is to be expected, as the various, lots are not comparable. 
Difi'erences in the conditions under which the berries were grown, in methods 
of drying, varying weather conditions at different times during the drying 
period, and differences in methods of handling or in conditions of storage 
before shipment might make as great a difference in keeping quality as 
would be found between water- and dry-raked berries grown and handled 
under otherwise similar conditions. 
It is apparent for the reasons indicated that conclusions as to the effect 
of water-raking on the keeping quality of cranberries are not warranted 
unless comparison is made between dry- and water-raked berries of the 
same variety from the same bog handled and stored under as nearly identical 
conditions as is possible. Such a comparison is made in table 2. 
These berries were examined within a week or ten days after their 
arrival in Chicago, so that the total time that had elapsed since they were 
put in barrels was probably not more than three weeks. One sample from a 
barrel was taken in each case. The results here indicate clearly a superiority 
in the keeping quality of the dry-raked berries. The average loss for the 
latter is 8.4 percent, while for the water-raked berries it is 16.5 percent. 
The length of time that the berries were kept in water is not definitely 
known in all cases. The Early Blacks were flooded at night and raked the 
next day. Unfortunately none of these were dry-raked, so that no com- 
parison can be made in their case except to note that they apparently have
