A light striped-bass chum rod is very suitable for the triple-tail when of good size. A multiplying reel and fifty yards of braided linen line, hooks No. 1-0 or 2-0, on heavy gut snells, and a brass box-swivel, make up the rest of the tackle. A sinker will probably not be needed as it is usually found in quiet coves about sandy shoals or grassy flats. I have taken it on both coasts of Florida, though it is more common on the east coast. I have also caught it in Chesapeake Bay and near Charleston, South Carolina, but never over five pounds in weight, though I have seen it taken in nets up to about ten pounds. Its short and rounded caudal fin, with the soft portions of the dorsal and anal fins, together, give the appearance of three tails, hence the name triple-tail, by which it is generally known. THE COBIA (_Rachycentron canadus_) _Rachycentron canadus._ The Cobia. Body elongate, fusiform, subcylindrical, covered with very small, smooth, adherent scales; head 4-1/4; depth 5-2/3; D. VIII-I, 26; A. II, 25; head broad, low, pikelike, the bones above appearing through the thin skin; mouth wide, nearly horizontal, the maxillary reaching front of eye; both jaws, vomer, palatines, and tongue with bands of short, sharp teeth; lower jaw longest; premaxillaries not protractile; preopercle unarmed; two dorsal fins, the spines of the first depressible in a groove; soft dorsal long and low, somewhat falcate, similar to, and nearly opposite, the anal; caudal fin strongly forked; no caudal keel; no finlets; gill-rakers short and stout; pectorals broad and falcate. The cobia, or sergeant-fish, is the only fish of its family, _Rachycentridæ_. It was first described by Linnæus, in 1766, from a specimen sent to him by Dr. Garden from South Carolina; it is allied to the mackerel tribe, and is found in all warm seas in the old and new worlds. On the Atlantic coast it is common from the Chesapeake Bay to Florida, but occasionally strays north to Cape Cod in the summer. It is rather rare on the west coast of Florida, but common on the east coast. It is a long and round-bodied fish, quite gracefully formed, with a depth of about one-fifth of its length. The head is broad and flat, something like that of the pike, with a wide mouth, and with jaws, roof of mouth, and tongue armed with bands of short, sharp teeth; the lower jaw projects. The back is olive-brown, or dusky, the sides lighter and silvery, and the belly white; a distinct broad and very dark stripe extends from the upper jaw and through the eye to the caudal fin, with an indistinct one above and below, and parallel with it. Owing to this dark stripe the cobia is sometimes called sergeant-fish, thus confounding it with the snook.
