24. But let these examples suffice to show, that fish are not altogether strangers to mankind, nor altogether void of human affection. But for a great and common demonstration of their unmixed and natural understanding, we find that there is not any fish that swims, unless they be such as stick and cling to the rocks, which is so easily taken by men, as asses are seized by wolves, bees by bee-eaters, grasshoppers by swallows, serpents by harts. And these last are therefore called ἔλαφοι, not from their swiftness (ἐλαφρότης), but from a faculty which they have of drawing serpents to them (ἕλκειν ὄφεις). So sheep call the wolf by the sound of their feet, and the panther allures to her paws both apes and other creatures by the fragrant smell of her body. But so suspicious is the sense of all water animals, and so watchful are they to avoid all baits and treacheries against them, by reason of their extraordinary cunning, that fishing thereby becomes no easy or single labor, but a toil that requires various instruments and many tricks of human cunning and deceit. This is apparent from examples near at hand. For no man desires an angling-rod too thick, though strong enough to hold against the twitches of the fish when taken; but rather they require it slender, lest by casting too great a shadow upon the water, it should frighten the suspicious creature. In the next place, they never knit too many knots in the line, but make it as smooth as may be, for that would too much discover the deceit; and then for the hairs which are next the hook, they endeavor to get the whitest they can meet with; for so, by reason of the likeness of color, they lie the more easily concealed in the water.
