Small flooding sections are a distinct advantage in water-raking, as 
the berries under such conditions need be submerged for only a short 
time. 
The cooler the flooding water, the better the chance of successful 
water-raking. Clear spring or brook water is preferable to dark- 
colored swamp water. : 
Intelligent and conscientious assistants to care for the drying of 
the hints are absolutely necessary if water-raking is to be success- 
fully practiced. 
In packing water-raked cranberries any lots which have dried 
slowly because of unfavorable weather or other conditions should be 
kept separate and marked or sold separately. 
Because of the variation in keeping quality of nels? cran- 
berries due to the conditions under which they are handled, it is 
doubtful whether water-raked berries should ever be mixed with or 
included with dry-raked or hand-picked berries.
