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 berries 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 separatety. 



Because of the variation in keeping quality of water-raked 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.
