This, of course, is intended to mislead watchers and keepers, and to throw the blame upon the non-guilty millowner. And, seeing that chloride of lime is used in various manufactures, the ruse sometimes succeeds. Many of the older poachers, however, discountenance this cowardly method, for by it the destruction of fish is wholesale, irrespective of size. The old hands use an old-fashioned net, to work which requires at least two men. The net is dragged along the quiet river reaches, a rope being attached to each end. The trout fly before it, and are drawn out upon the first bed of pebbles. In this way great hauls are often made. To prevent this species of poaching, stakes are driven into trout stream beds; but they are not of much avail. When it is known that a "reach" is staked, a third man wades behind the net and lifts it over. A better method to prevent river poaching is to throw loose thorn bushes into the bed of the stream. In trailing along the bottom the net becomes entangled, and long before it can be unloosed the fish have escaped. This wholesale instrument of fish poaching is now rarely used. The net is necessarily large and cumbersome. Wet, it is as much as two men can carry, and when caught in the act, there is nothing for it but to abandon the net and run. This is an effectual check for a time, as a new net takes long to knit and is expensive, at least to the poacher. When salmon and trout are spawning their senses seem somewhat dulled, and they are taken out of the water at night by click-hooks. In this kind of river poaching a lighted tar brand is used to show the whereabouts of the fish. A light, too, attracts salmon. Of course, this can only be attempted when the beats of the watchers and keepers are known. The older generation of poachers, who have died or are fast dying out, seem to have taken the receipt for preparing salmon roe with them. For this once deadly bait is now rarely used. Here is a field incident.
