These may be divided into Coral Snakes, Moccasins, and Rattlers. The coral snakes are found in the Southern States. They are very much like harmless snakes in shape, but are easily distinguished by their remarkable colors, "broad alternating rings of red and black, the latter bordered with very narrow rings of yellow." The Rattlesnakes are readily told at once by the rattle. But the Moccasins are not so easy. There are two kinds: the Water Moccasin, or Cotton-mouth, found in South Carolina, Georgia, Florida, Alabama, and Louisiana, and the Copperhead, which is the Highland, or Northern Moccasin or Pilot Snake, found from Massachusetts to Florida and west to Illinois and Texas.

The pupil of the eye is an upright line, as in a cat; the harmless snakes have a round pupil. The Moccasins have a single row of plates under the tail, while the harmless snakes have a double row. The Water Moccasin is dull olive with wide black transverse bands. The Copperhead is dull hazel brown, marked across the back with dumb-bells of reddish brown; the top of the head more or less coppery. Both Moccasins and Rattlers have a flat triangular head, which is much wider than the thin neck; while most harmless snakes have a narrow head that shades off into the neck. Rattlesnakes are found generally distributed over the United States, southern Ontario, southern Alberta, and Saskatchewan. How Does a Snake Bite Remember, the tongue is a feeler, not a sting. The "stinging" is done by two long hollow teeth, or fangs, through which the poison is squirted into the wound. The striking distance of a snake is about one-third the creature's length, and the stroke is so swift that no creature can dodge it. The snake can strike farthest and surest when it is ready coiled, but can strike a little way when traveling. You cannot disarm a poisonous snake without killing it. If the fangs are removed others come quickly to take their place. In fact, a number of small, half-grown fangs are always waiting ready to be developed. In Case of Snake Bite First, keep cool, and remember that the bite of American snakes is seldom fatal if the proper measures are followed.
