make a line, or semicircle, to encompass a shoal of haddocks and cod,
confining them within certain limits near the shore, and eating them as
occasion requires. For the haddocks and cod are always found near the shore
without any dog-fish among them, and the dog-fish further off without any
haddocks or cod; and yet the former are known to prey upon the latter, and
in some years devour such immense quantities as to render this fishery more
expensive than profitable.

3. The remora, when he wishes to remove his situation, as he is a very slow
swimmer, is content to take an outside place on whatever conveyance is
going his way; nor can the cunning animal be tempted to quit his hold of a
ship when she is sailing, not even for the lucre of a piece of pork, lest
it should endanger the loss of his passage: at other times he is easily
caught with the hook.

4. The crab-fish, like many other testaceous animals, annually changes its
shell; it is then in a soft state, covered only with a mucous membrane, and
conceals itself in holes in the sand or under weeds; at this place a hard
shelled crab always stands centinel, to prevent the sea insects from
injuring the other in its defenceless state; and the fishermen from his
appearance know where to find the soft ones, which they use for baits in
catching other fish.

And though the hard shelled crab, when he is on this duty, advances boldly
to meet the foe, and will with difficulty quit the field; yet at other
times he shews great timidity, and has a wonderful speed in attempting his
escape; and, if often interrupted, will pretend death like the spider, and
watch an opportunity to sink himself into the sand, keeping only his eyes
above. My ingenious friend Mr. Burdett, who favoured me with these accounts
at the time he was surveying the coasts, thinks the commerce between the
