of the day in this month, and is imitated by dun hackles for wings and legs, and an olive dubbing for body. In milder weather, in morning and evening in this month, and through April, the green tail, or grannom, comes on in great quantities, and is well imitated by a hen pheasant’s wing feather, a gray or red hackle for legs, and a dark peacock’s harle, or dark hare’s ear fur, for the body. The same kind of fly, of a larger size, with paler wings, kills well in the evening, through May or June. The imitation of a water insect called the spider fly, with a lead-coloured body and woodcock’s wings, is said to be a killing bait, on this and other rivers, in the end of April and beginning of May; but I never happened to see it on the water. The dark alder fly, in May and June, is taken greedily by the fish: it is imitated by a dark-shaded pheasant’s wing, black hackle for legs, and a peacock’s harle, ribbed with red silk, for the body. At this season, and in July, imitations of the black and red palmer worms, which I believe are taken for black or brown, or red beetles or cockchaffers, kill well; and, in dark weather, there are usually very light duns on the water. In August, imitations of the house fly and blue bottle, and the red and black ant fly, are taken, and are particularly killing after floods in autumn, when great quantities of the fly are destroyed and washed down the river. In this month, in cloudy days, pale-blue duns often appear; and they are still more common in September. Throughout the summer and autumn, in fine calm evenings, a large dun fly, with a pale yellow body, is greedily taken by grayling after sunset; and the imitation of it is very killing. In the end of October, and through November, there is no fly fishing but in the middle of the day, when imitations of the smaller duns may be used with great success; and I have often seen the fish sport most, and fly fishing pursued with the greatest success, in bright sunshine, from twelve till half-past two o’clock, after severe frosts in the morning; and I once caught, under these circumstances, a very fine dish of fish on the 7th of November. It was in the year 1816; the summer and autumn had been peculiarly cold and wet, and, probably in consequence of this, the flies were in smaller quantity at their usual season, and there was a greater proportion later in the year.
