^hr- -extremely low food value of oysters as compared with the other sea 

 foods should be noted. Oysters should be valued for their flavor and not 

 £or their food value. It requires about three pints of oysters to contain the 

 amount of nutritive material contained in a quart of milk. Fish, in gen- 

 eral, however, is a useful and economical food.
