And so the Silver Doctor and the Golden Shiner, as they dubbed each other, went trudging along the bank of the merry stream together. The Doctor, lightly equipped with only rod, fly-book, and creel, sometimes relieved the Shiner by toting his minnow bucket or minnow net. They were fishing a rocky, gently flowing river, characteristic of the Blue Grass section. They stopped at a broad, lakelike expansion of the stream, caused by a mill-dam, and, in a quiet cove at the entrance of a clear brook. Golden Shiner proceeded to fill his minnow bucket with lively minnows, using for the purpose an umbrella-like folding net. This he attached to a long, stout pole, and, after baiting it with crushed biscuit, lowered it into the water. In a short time he had all the bait necessary--chubs, shiners, and steelbacks. "The golden shiner is the best of all," said he, "especially for roily or milky water; but the chub and steelback are stronger and livelier on the hook, and for very clear water are good enough." They then proceeded below the mill-dam, where there was a strong riffle, with likely-looking pools and eddies. "The proper way to hook a minnow is through the lips," continued Golden Shiner, "especially for casting. One can give a more natural motion to the minnow on drawing it through the water. For still-fishing, hooking through the tail or under the back fin will answer; but even then I prefer my method, unless the minnow is less than two inches in length." And he made a long cast toward the eddy of a large boulder. "For the same reason," acquiesced Silver Doctor, "artificial flies are tied with the head next the snell,"--industriously casting to right and left over the riffle. "But some flies are tied with the tail next to the snell," ventured Shiner. "That is true, but it is unnatural. I never saw an insect swim tail first up-stream. Nature is the best teacher, and one should endeavor to follow her lead." Just then the Doctor snapped off his point fly. Upon examination he found that the snell was dry and brittle next to the head of the fly, though he had previously soaked it well in a glass of water. He discovered that a drop of shellac varnish had encroached beyond the head of the fly for perhaps the sixteenth of an inch on the snell. This portion, being waterproof, remained dry and brittle--a very common fault with cheap flies. "This fly," said the Doctor, "was given to me for trial by Judge Hackle. He tied it himself. The broken end of the snell still shows a portion of shellac coating." "I never thought of that before," remarked Shiner. "No doubt many flies are cracked off from the same cause."
