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.
