80 THE ECOXOMIC MOLLUSCA OF ACADIA. 



The only way in which the Mussel seems to be of 

 injury to man, excepting the cases spoken of above, is when 

 it grows on Oyster-beds. It grows faster, lives on coarser 

 food, and is altogether better fitted for the struggle for 

 existence than the Oyster. It also collects mud, and by all 

 of these causes tend to crowd out the more valuable Mollusc. 

 We have not heard that it is known to do any injury to our 

 •Oyster-beds in this way.
