t. Mva arenaria Linuaeus. 



Xuiuerous experiments have resulted in the conclusion that 

 of the bivalves meutioued above this clam has the greatest tenac- 

 it\- of life aud will remain in an edible condition long-er than any 

 of the other s])ecies, after having been removed from the water. 

 I!\' icing the clam it has l)een kept alive for a period of 14 days 

 after its removal from salt water. This would permit of its 

 transportation for a considerable distance from the coast if the 

 same were made under ])ro])er conditions. If ke])t at low tem- 

 ]:)erature this species ma\' remain in fit condition for food for as 

 long as a week after having been taken out of the water. 



Mva arenaria is abundant in the Siuslaw River and Coos 

 Bay both of which are in direct connection l)y railroad with W'il-
