It frequents sandy shoals, and also rocky shores, feeding on small fishes and crustaceans. It is a good pan-fish, growing to about a foot in length, but usually to six or eight inches. The same tackle and baits used for the hinds, coney, and nigger-fish will also answer well for the sand-fish, which consists of black-bass rod, braided linen line, size F, hooks No. 1 or 1-0, and suitable sinker and swivel. It is a good game-fish for its size on the light tackle just mentioned, and is well worth a trial on account of its beauty, and excellence for the table, even if its gameness is not considered. While engaged in a scientific expedition to Florida many years ago, my vessel ran aground one afternoon in Barnes Sound, south-west of Biscayne Bay. The bottom was a sandy marl and quite soft, so that we were unable to use the setting poles to any advantage in moving the boat. I observed quite a school of fish surrounding the vessel, which proved to be sand-fish. I put out a stake to mark the stage of the tide, and while waiting for the flood tide I put in the time fishing, and soon had enough sand-fish for supper and breakfast. This was rather fortunate, as we were still aground the next morning, for strange to say the depth of the water had neither increased nor diminished for sixteen hours; there was no tide in that remote corner of the universe. We then took out the ballast of about a ton of pig-iron and put it in the dory we had intow. This lightened up the vessel enough to enable us to shove her off into deeper water. I think we never enjoyed any fish quite so much as those delicious little sand-fish, and it has ever since been one of my favorite fishes. CHAPTER XVI THE CAVALLI FAMILY (_Carangidæ_) The members of this family differ from the true mackerels by a less number of spines in the first dorsal fin, and in having but two spines in the anal fin, and no detached finlets; also in having smaller teeth. Some of the species are described in another volume of this series, to which the reader is referred. _Carangus chrysos._ The Runner. Body oblong, moderately elevated, the dorsal and ventral outlines about equally arched; head 3-3/4; depth 3-1/4; eye 3-1/2; lateral line with 50 scutes; D. VIII-I, 24; A. II-I, 19; profile forms a uniform curve; snout rather sharp; mouth moderate, slightly oblique, maxillary reaching middle of orbit; teeth comparatively large; a single series in lower jaw; upper jaw with an inner series of smaller teeth; no canines; teeth on vomer, palatines, and tongue; gill-rakers long and numerous; pectoral fin not longer than head; scales moderate; cheeks and breast scaly; black opercular spot.
