— So far as our information and observation have 
extended, this species is stationary through the 
year in the northern parts of Scotland, while in 
the south, and in some parts of England, it is 
migratory. It possesses the same predatory 
nabits with the last, but from being confined 
almost in distribution to the coast, they are not 
so severely or generally felt. It destroys the 
eggs and young of birds, and where not defended, 
robs the nests of the sea fowl ; it is also said occa- 
sionally to attack young lambs. Its great fund 
of subsistence, however, is on the shore, and the 
various marine animal productions which are cast 
up with every tide furnish it with a constant 
supply, which, perhaps, in some measure checks 
the degree of mischief which it might otherwise 
commit on the productions of cultivation. As 
we previously remarked, in those localities where 
it abounds, it fills almost entirely the place of the 
last, extending inland for five or six miles; and 
beyond that distance, unless where the country is 
intersected with bays or long salt water lochs,
