A hunter needs to know horse tracks as much as those of wild game. The greater size and roundness of horse tracks distinguish them from those of mules and asses. When shod the toe calks are a strong feature; when without shoes the unbroken front edge is distinctive. Some horses walk in correct register; some do not. Mules are more exact than horses. When trotting the arrangement is much as in walking, but the spaces are longer and the hind-feet track farther ahead of the front feet. In galloping the arrangement is much as in the white-tailed deer.] [Illustration: BARREN GROUND CARIBOU The caribou track is distinguished by its great spread and the fact that the clouts or hind hoofs touch the ground, even on a hard surface. I know of no difference but size between the tracks of the various caribou and reindeer. The probabilities of time and locality help in determining the species, but it need never be mistaken for that of any other type of deer. In winter the caribou’s tracks in the snow show that its feet, instead of being raised high at each step, like those of a Virginia or mule deer, drag through the snow like those of domestic cattle.] [Illustration: COAST BLACK-TAILED DOE I know of nothing but probabilities to distinguish the walking tracks of the coast deer from those of nearly related species. This track of a bounding female shows a peculiar grouping that corresponds fairly with the bounding action characteristic of the species.] [Illustration: ANTELOPE The different styles of front and back feet is a marked character of the antelope’s track and is best seen in the walk. In galloping all of these animals leave the hind tracks ahead of the fore tracks, but disturb the ground, so that almost no characteristic marks are to be seen.] [Illustration: CANADA LYNX This track I sketched on the Athabasca River. In summer the track of a lynx shows the toe-pads faintly; in winter all are muffled in hair and the track is much larger. “The feet in winter are so broad that they serve admirably for support in deep snow” (see page 409).] [Illustration: TEXAN WILDCAT This track, while akin to that of a cat (see page 487), has some very well-marked characteristics. The complicated outline of the heel-pads is striking. This, with its large size, will distinguish it from the track of a house cat. The claws do not show.] [_Reprinted from_ SCIENCE, _N.
