and their Spawn converted into the young brood, the Spring following they naturally descend with the stream, and by gree∣dy Millers and others are commonly the greatest part of them intercepted in their Pots; yea, sometimes in so great quantities, that for want of a present Market they have given them to their Swine. All which are the principal causes of the great scarcity of that Fish in these parts of England.
There is a sort of Engine, by some termed a Hawk, made al∣most like unto a Fish-pot, being a square frame of Timber fit∣ted to the place you intend to set it in, and wrought with wire to a point almost, so that what Fish soever go through the same, cannot go back again. These placed the one where the River enters into your Land, the other where it runs out, with the Points of each towards you, any Fish whatsoever that moves with or against the water, when they are once within the Hawks, cannot get back again. In case the River be broad, you may place two or three of these at an end in it; a frame of Timber being set in the water that it break not out on either side, nor under, lest your Fish escape. These Hawks ought to be made moveable, to take off or on, as you see occasion.
But in case you are in danger of Land-floods, or that you have not the command of the Land on both sides, or of suchlike im∣pediment; then may you cut a large Channel out of the sides of the River, and as deep as the bottom of the River, with some part of the Current through it, and place these Hawks at each end of it, the better to intice the Fish into it. At some conveni∣ent distance from the River, and in the Piscary, on the top of a stake pitch'd in the midst of the water, and a little above the wa∣ter, fix a Laton-case, in form of a Cylinder, about three or four inches Diameter, and twelve inches long, in which set a Candle burning in dark nights, the light whereof shines only upwards and downwards: it must be open at the top, because it preserves it burning: the downward light intices the Fish into your Pisca∣ry; so that no Fish passes up nor down the River, but will seek their way through the Hawk into the light. By this very means I have known a Piscary well stored in a few nights.
There is a Net made round, and at each end a Hawk, that be∣ing set in the water and depressed by Plummets or Stones, and having in the in-side thereof shining shells, or red cloth, or such∣like inticements, the Fish will seek their way in, but cannot get out.
As for Fishing in the night by fire, and stupifying of Fish with unwholesome Baits, or with Lime, or suchlike, being ways used by evil-minded persons, that rather destroy the properties of other men, than lawfully use them for their necessary subsistence; I shall decline any advice or directions in that kinde, and prose∣cute that most lawful, just, and honest way of Angling, so much celebrated by the Ingenious of every degree.
