The Common Mussel.
'Travelling is not good for us; we travel so seldom. How much more dignified
leisure hath a Mussel glued to his impassable rocky limit two inches
square! He hears the tide roll over him, backwards and forwards,
twice a day (as the Salisbury coach goes and returns in eight and forty
hours), but knows better than to take an outside place on the top on't.
He is the owl of the sea, Minerva's fish, the fish of wisdom.'
C. Lamb to B. Barton.
