The green and brown May fly patterns are representative of the corresponding Ephemeridæ, and their usefulness upon streams when and where the May fly is abundant is sufficiently obvious. The Caddis flies in the nomenclature of the dry fly are known as "sedges"; the silver sedge and brown sedge belong to this class. The spent gnat pattern represents the female May fly which, having voided her eggs upon the water, thereafter falls upon the surface of the stream practically lifeless and with wings flat and outstretched. The spent gnat, accordingly, is dressed with horizontal, not erect, wings.
For carrying eyed-flies various fly-boxes are furnished by the tackle dealers. The method of holding the flies is usually by means of a metal clip, although some boxes have several small compartments with transparent (celluloid) covers, and others have cork strips into which the fly may be fastened. The last sort is the least satisfactory. As a rule, in the ordinary form of eyed fly box the metal clips are set very closely together, and it is advisable to procure a box capable of holding at least double the number of flies you intend to carry, so that they may be inserted without crushing and be easily distinguished and removed.
Paraffin oil, or some one of the other similar waterproofing liquids furnished by the tackle dealers, is a necessity to the dry-fly caster. A floating fly, if perfectly dry, will float fairly well for a number of casts without the use of paraffin; but it soon becomes drowned and sodden and very difficult to dry out by merely false casting. Whatever preparation may be used (and I have found very little practical difference in them) it should be carried in a small bottle having a stopper with brush attached. Apply the oil to the fly lightly, and remove the superfluous liquid by pressing the fly between folds in your handkerchief. It is usually practicable to prepare a number of flies in this way before going to the stream, thus obviating the the necessity of carrying the "oiler."
It would seem unnecessary to consider the matter of the creel, waders and other general fly-fishing equipment, as these are familiar to every fly-fisherman of any experience. However, for the benefit of the virtual beginner it may be said that a rather larger basket than that usually advised to the trout-fisherman say a creel of twenty-pound size--is preferable for many reasons. The new style sling, which suspends the basket from the left shoulder, should be used.
