The fly-rod, reel, line, and leader ordinarily employed for trout-fishing may be used also for grayling, though I would advise some modifications. While a first-class split-bamboo rod of three and a half or four ounces may be advantageously used by an angler who knows how to handle a very light rod, I prefer one of five or six ounces. Such a rod is certainly light enough to be used all day without fatigue, and it is well to have the resourceful reserve of an ounce or two for emergencies. In any case it should not exceed ten and one-half feet in length, if built on the modern plan, where most of the pliancy is in its upper two-thirds, the lower third being stiffish and springy, constituting its backbone. A very good rod can be constructed with ash butt, and lancewood, greenheart, or bethabara upper pieces, and one that will be almost as light as split-bamboo, and certainly more serviceable in the long run. I would also advise flush, non-dowelled joints, and reel-bands instead of a solid reel-seat, the latter being of no advantage and only adding to the weight of the rod; moreover, it is now put on the cheapest rods to make them sell. A plain groove for the reel, with bands, is very much better. As a matter of course the line should be of braided silk, enamelled, and suited to the weight of the rod, as small as size G, but not larger than size E. It may be level, but a tapered line is better for casting, and is also better adapted for the delicate leader that must be employed. A tapered leader six feet long is best, but should not be shorter than four feet. It must be made of the very best silkworm gut fibre, round, clear, and unstained. The distal end should be made of the finest drawn gut, known as gossamer, and taper to the larger or proximal end, which should be the smallest undrawn gut. In England the most delicate leaders and extremely small flies are employed for grayling. The flies are usually tied on Pennell hooks, turndown eye, sizes 0, 00, 000, Kendal scale, which are smaller than No. 12, Redditch scale, the latter being the smallest size commonly used in America. The favorite flies in England have yellowish--lemon to orange--bodies, and bodies of peacock harl, either green or bronze. Flies with purplish, black, or slate-colored bodies are more sparingly employed. They are either hackles or split-winged flies. The formulas for some of the favorites are as follows:-- _Red Tag._ Body bright green harl from the "moon" of a peacock's feather; hackle, bright red cock's hackle; tag, bright red wool; hook, No. 0, Kendal scale. _Orange Bumble._ Body, orange floss silk, ribbed with a strand of peacock's sword feather and fine flat gold tinsel; hackle, honey dun cock, wrapped all down the body; hook No. 0, Kendal scale. _Green Insect._ Body, bright green peacock's harl; hackled with a soft silver-gray hen's feather; hook No. 0, Kendal scale.
