Tlie following extracts from tables compiled from work done 

 at Coos, Tillamook and Netarts Bays in Oregon, and at Hum- 

 boldt Bay, Calif., give a very good idea of the conditions prevail- 

 ing at each place. Eastern oysters were planted in the latter lo- 

 cality in November, 1896, contemporaneously witii those planted 

 at Yaquina Bay. 



Coos Bay. 



It will be noted from this table that except at Marshfield the 

 water approaches in saltness that of the ocean.

Although the Netarts Bay Oyster is the same species {Ostrea. 

 Ivrida) as that found at Yaquina Bay, the extreme saltiness of 

 the water of this bay gives it a characteristic salty taste, much 

 prized by some.
