The first and most striking difference to be observed between the systems of the two countries is in the comparative size of the flies, those of America, following the natural insect, being larger, and, probably for a similar reason, gaudier. It is a remarkable fact that the most gaudy of all, the scarlet ibis, is prominently successful alone in the streams of Long Island and of the British Provinces. As many of the Long Island trout yearly migrate to the sea, in which peculiarity they resemble the fish of the latter place, it may be that this fly is only a favorite with sea-going fish. A little tinsel wound round the body is supposed to improve its efficiency, as some fishermen suggest from a resemblance to the principal Winter food of the trout, the salt water minnow.

The earliest fly on the Long Island ponds is a dark water fly, with a brownish red body and legs, and black, filmy, transparent wings. It is rather large, is wafted along upon and occasionally rises from the water, and never appears in any considerable numbers. It is usually represented by the English or female cow-dung, which, although not similar in coloring, presents somewhat the same general appearance. The wings, being transparent, should not be imitated with a black feather, although I have had great success when these flies were on the water with a fly that had black wings and a claret body and legs. The orange dun, with a body tinged with brown, would be a good imitation.

The next natural fly, which is smaller than the last, is of a greenish yellow, and is also caricatured by the cow-dung. But it is decidedly recommended to make a more faithful copy, which the writer has done with eminent success. In speaking of this matter, it is important to add that the midges, such as the black gnat and others, are out earlier, and it is to the larger flies alone that reference is made. The earliest of the species mentioned appears in ordinary seasons about the first of March, and the next about a week later. At this period, and at all periods, of a bright day a large black gnat with black hackle, black or dark blue body, silver tinsel at the tail, and dark wings, is usually successful.

Shortly after the greenish fly, come many others, appearing almost together, and among them the cow-dung and the yellow sally, the latter occasionally fairly covering the water. About this time the professor answers well, although I have never discovered its prototype, if it has any, and shortly afterward an unimitated brown fly, together with the blue blow and cinnamon, and in warm weather innumerable others. In the latter part of April and early part of May, the bushes and streams are alive with the gay little beauties, of every color, size and shape, and the fish make them their principal food. But the waters are growing clear, the deception is becoming apparent to the fish’s eye, and the insects, though in reality larger, must have more delicate substitutes. At such times a small red bodied fly, with dun wings, has proved extremely killing, and although large, white, gelatinous ephemeræ swim upon the water, the midges are on quiet days the most successful; and when the sky is bright, subdued colors are in principal demand.

In June there are prominent, among many others, the black fly, with body, wings, legs and antennæ all of the same sable hue, busy the entire day dancing over the water a veritable dance of death, for it is often terminated by the fatal rush of the watchful trout; a dun fly, with greyish dun mottled wings, grey legs, and light green body; another fly with similar wings, but red legs, and a rich brown body—none of these having any whisks in their tails; another beautiful and delicate yellow fly, that appears generally in the morning and evening, and flies heavily and slowly from place to place, till it falls suddenly, and is forever submerged in the cruel waters. Its legs, body and wings are yellow, the latter being the palest, and it has two short whisks and antennæ of the same color. All the foregoing have four wings, in the black and yellow varieties strongly reticulated, and all but the last swim well under water. Toward night a frail whitish fly makes its appearance still more fragile than its yellow compeer; it has two wings, a thick body and long whisks. The eyes of the yellow and white fly are black spots, and although I never have done much with a white fly, a small yellowish drake was successful when the yellow flies were abundant. A better imitation however could be made of pure yellow.

On one occasion I was struck with the fact that although I did not know these insects were on the water, my only successful flies were a yellowish fly, a green-bodied, dun-winged fly, and a similar fly with a brown body, and I hit on them accidentally after trying a great variety.

Hackles, in our Long Island ponds, are, by universal testimony, a failure, and the palmers worthless; and throughout the breadth and length of our country, the winged flies are vastly preferable. The hackles and palmers are intended to represent the caterpillars, which our fish very sensibly ignore alongside of the innumerable beautiful, delicate and gaudy flies, and which under no circumstances are found except in the fresh-water brooks. Through all the early Spring, the stomachs of the trout will be found filled with the shells of the caddis, and these, if they could be obtained, would doubtless be a killing bait. Fortunately they cannot be, and are not to my knowledge used here at all.

In our mountain streams the fish are generally extremely numerous, though small, and will eagerly seize any fly presented to them, vying with one another to be first. The following is a good assortment, and will, in addition to those already mentioned, be sufficient for all waters: The alder-fly, English partridge hackle, hackles of all colors, red and black ants, the devil-fly with a yellow body, the tail of one red and one black whisk, black hackles and red and black wings, dark mackerel, red spinner, English blue jay, fern-fly, orange dun, the camlets of various colors, grey, dun and black midges, the coachman, the stone-fly, the May-flies, millers for night-work, the sand-fly, the various other duns, the turkey brown, and a large light grey fly.

As each maker employs different colors and feathers for the same fly, these descriptions are rather indefinite but by taking a number of various shades, you can readily select the most effective. The well-known flies should be dressed after Ronalds as far as practicable. It is to be regretted that there is not more uniformity and pride in, or practical acquaintance with, the subject among our principal tackle-makers. With the English makers it has always been an especial care that their flies should be dressed well and with uniformity; but here, anything that can be palmed off on an ignorant or indulgent public, or a barbarous country trade, is all that is desired. It is better always to send a pattern, with instructions to copy it precisely, and that no originality of variation will be permitted. Then, and then only, can you obtain what you wish. So much for trout-flies.

To make a salmon-fly, the following additional directions, most of which apply equally to carefully made trout-flies, will be found convenient. Tie on the gut as before directed; upon reaching the bend, fasten the spring pliers on to the thread, and do not take them off till the fly is finished. Take two turns with the silk over a strip of tinsel, pass the latter several times round the hook to form the tag, fasten it with the silk and cut it off; introduce the floss for the tip, take several turns evenly, tie it down and cut off the end; introduce the tail and then a piece of herl, wind the herl at the root of the tail and fasten it; take in a new piece of tinsel and a hackle by rubbing back all the fibres but a few at the point; leave both pointing from the head. Take a small piece of mohair between your fingers, break it over and over again into small pieces, lengthen it out and twist it round the silk toward the left, as otherwise it will unlay in winding; wind the silk and mohair together round the shank to the shoulder, leave a space of bare hook sufficient for the wings. Wind in loose coils first the tinsel and then the hackle, and fasten both at the shoulder. Strip two wings from feathers that have been taken from the opposite sides of the bird, place them together, hold them firmly on the hook with the left forefinger and thumb, and fasten them securely. Cut off the ends, insert a piece of herl, wind it over the head and tie it down. Lay the end of the silk back down the shank, and take three turns with the other part over silk, hook and gut; pass the gut end through the loop three times and draw the silk tight. Two turns of silk should hold the different parts during the entire operation, and a couple of half hitches under the wings at the shoulders are sometimes used to fasten off. The feathers should be mated to make neat wings, and if they are laid right side out they will close round the hook; if otherwise, they will stand out. Do not fail to varnish at the head with wood varnish, or some other kind that will dry rapidly. The hackle may be introduced at the shoulder. Where herl or floss is used for the body, it is wound on separately from the tying silk, which is sometimes passed in loose coils afterward. A second hackle of a different color, or a feather wound like a hackle, may be introduced after the first, or after the wings and before the head is finished, and is called the legs. The wings must be tied above the dubbing on the hook, or they are liable to turn, especially where floss silk is used for the body.
