The angler should always have the wind at his back, the sun or moon before him, as much as possible; in cold, windy weather especially, he should be on the weather-shore, where the fish then resort for warmth, and the calmness of the water. The east wind, for angling, has been universally execrated, but probably this may not hold good in rivers running from east to west.
At the conflux of rivers that ebb and flow, it is best angling at the ebb; sometimes, when the tide is not strong, they will bite at flood, but very rarely at high water.
Deep waters are best to angle in, as the fish are not then disturbed by wind or weather.
The best periods are from April to October; from three until nine in the morning, and from three in the afternoon, so long as there is light; the later, the better sport. In winter, the weather and times are much alike; the warmest is most preferable.
During the summer, even when the water is quite low and clear, no wind stirring, and the sun shining in its utmost lustre, and in the hottest part of the day, it is insisted, trout may be taken (although very few anglers are disposed to credit it), with a small wren’s-tail, grouse, smoky dun, and black hackles, fishing straight down the water by the sides of streams and banks; keeping out of sight, and with as long a line as can conveniently be managed, with the foot-length very fine: they may be often seen with their fins above water, at which time they will eagerly snap at the abovementioned flies; and though upon hooking one the rest will fly off, they will soon be composed, and return for two or three times.
Right of Fishing.—It has been held that where the lord of the manor hath the soil on both sides of the river, it is a good evidence that he hath right of fishing; and it puts the proof upon him who claims liberam piscariam; but, where a river ebbs and flows, and is an arm of the sea, there it is common to all, and he who claims a privilege to himself, must prove it; for if the trespass is brought for fishing there, the defendant may justify that the place is brachium maris, in quo unusquique subditus domini regis habet et habere debet liberam piscariam. In the Severn the soil belongs to the owners of the land on each side; and the soil of the river Thames is in the king, but the fishing is common to all. He who is owner of the soil of a private river, hath separata piscaria; and he that hath libera piscaria, hath a property in the fish, and may bring a possessory action for them; but communis piscaria is like the case of all other commons. One that has a close pond, in which there are fish, may call them pisces suas, in an indictment, &c.; but he cannot call them bona et catalla, if they be not in tanks. There needs no privilege to make a fish-pond, as there doth in case of a warren.—Ency. Brit.—Daniel—Jesse—Wild Sports, &c.
