The "enameled water-proof" lines are the best. These are braided from boiled silk, and prepared to resist the action of water, which will cause the decay of an ordinary line. Of the various sizes, which are distinguished by letters, that known as F is perhaps most desirable, although either E or F will answer the purpose. The line should be "level," not tapering, and at least twenty-five yards in length. This will be wound upon a "click" reel of equal capacity, preferably nickel-plated. But this is of less importance than the internal construction of the reel, for which you should have the maker's guarantee. Now come the flies. There are names enough to fill a directory, and a greater variety of colors than the woods show in autumn. A few flies like the "Montreal," "Professor," "Scarlet Ibis," "Coachman," and "the Hackles," are to be found in almost every angler's book. For the rest, it will be well to learn, from some experienced angler or intelligent dealer, the flies best suited to the particular waters which you intend to fish. At the Rangeley lakes, for example, you will find that large, gaudy flies are much used, like the "Parmachenee Belle," "Silver and Golden Doctor," and "Grizzly King," and there is one local fly called the "Katoodle Bug." In the Adirondacks, smaller flies of quieter colors are favored. For brook-fishing, very small flies of neutral tints are much used except when the water is very dark. A fly-book will be needed to contain flies and also leaders. The leader is a piece of "silk-worm gut," which should be about six feet in length. One end is fastened to the line, and the stretcher-fly is made fast at the other. One or two other flies, called droppers, are usually attached at intervals of two feet or more along the leader. Before making your choice, the leaders should be closely examined to see whether any part is frayed or cracked. They can be tested by a pull of four or five pounds on a spring balance. The leader is used as being less conspicuous than the line in the water, and, therefore, less likely to frighten away trout approaching the flies. Most leaders are dyed a misty bluish color which, it is thought, will escape even the keen eyes of the trout. A landing-net, the size and strength of which depend upon the fishing-ground, completes the list of tackle. [Illustration: TROUT FLIES.] The next step is to learn how to cast a fly, and here practice and the advice of some experienced fly-fisherman will be worth more than printed instructions.
