THE RIVER CRAY-FISH, (_Potamobius fluviatilis_.)

The fresh-water Cray-fish very much resembles the lobster in

appearance, but is considerably broader in its proportions. It is

commonly found in the tributary streams of large rivers, inhabiting the

banks, in which it burrows, and feeding on any animal substance that

may happen to come in its way.

The Cray-fish is taken in various ways, sometimes by the hand, which

is thrust into the holes in which they burrow. Another method is thus

described:—

Procure a dozen little rods, about five feet in length, and the

thickness of the thumb,—split them at the smallest end, and by way

of bait, place a frog, or a piece of putrid flesh in the cleft; take

then the rods by their thickest end, and hold the bait at the entrance

of the little holes where you suspect your prey to be; if they are

there, they will generally come out to seize the bait. As soon as you

perceive them, hold a small landing-net underneath, and raise the bait

suddenly, and the Cray-fish will either be brought up along with the

bait, or will fall back into the net.

Another method noticed, consists in first burying a dead cat, or a

hare, in a dunghill, for eight days, and then placing it in the midst

of a bush of tangled thorns and brambles, which is thrown into the

water, in the place frequented by the Cray-fish. After it has remained

there a few hours it may be drawn up, when the shell-fish will be found

partaking of their delicate fare, and the tangled bush will effectually

prevent their escape.
