THEAETETUS: True.

STRANGER: And of swimming animals, one class lives on the wing and the
other in the water?

THEAETETUS: Certainly.

STRANGER: Fowling is the general term under which the hunting of all birds
is included.

THEAETETUS: True.

STRANGER: The hunting of animals who live in the water has the general
name of fishing.

THEAETETUS: Yes.

STRANGER: And this sort of hunting may be further divided also into two
principal kinds?

THEAETETUS: What are they?

STRANGER: There is one kind which takes them in nets, another which takes
them by a blow.

THEAETETUS: What do you mean, and how do you distinguish them?

STRANGER: As to the first kind--all that surrounds and encloses anything
to prevent egress, may be rightly called an enclosure.
