Hermit-Crabs.
'Finding on the shoar
Som handsome shell, whose native lord of late
Was dispossessed by the doom of Fate,
Therein he enters, and he takes possession
Of th' empty harbour, by the free concession
Of Nature's law—who goods that owner want,
Alwaies allots to the first occupant.'—Du Bartas.
