Having cut it off, he held it up, and counted the joints, of which the snake--one of the largest of its species--had twenty. Cutting them apart he showed us how the apparatus was arranged. I could best describe it by saying it looked as if a number of small cups were placed one within the other, flattened on both sides, with rings round the edges and slightly decreasing in size towards the end, the last joint being the smallest and forming a knob. These cups are horny and loosely joined, so as to produce the rattling sound for which the creature is noted. Every year of its life a new joint is supposed to be added, so that the reptile killed by the black snake, must have been twenty years old. Each joint was in form somewhat like the tip end of my thumb. I have often since seen rattlesnakes, though seldom one so large. Generally I have found them coiled up among the dry herbage, with the tip of the tail raised in the centre of the coil. On seeing me approach the creatures have instantly produced a quivering movement of their tails, which made the joints of the rattle shake against each other. I cannot find expressions to describe the sound, but having once heard it I never failed to approach with caution, or to keep out of the creatures' way. "We will now have a look at the blue or black snake, or, as it is called here, `the Racer,'" observed the Dominie, "and a `racer' it is rightly called, for it moves along, as we saw this one do through the grass, at the speed of lightning. When I first saw one I fancied from the noise that it made rushing through the dried grass, that it was a rattle-snake and shot the creature before I discovered that it was of a non-venomous species. It can, however, bite very severely with its sharp teeth, and I once saw a poor man almost frightened to death, believing that he had been bitten by a rattle-snake. You see that the head is supplied with a formidable array of teeth, but its tail is much longer and finer than that of the rattle-snake. It can, however, open its jaws wide enough to gulp down a good-sized bird. It gains its name of the blue or black snake from the colour of its back, which is, as you see, blue-black; while the underside is of an ashen slate hue. The tints vary slightly, and hence the two names. Its tail is fine in the extreme, and enables it to steer its rapid course through the herbage." We let our Dominie run on, though we were well acquainted with the black snake, for several had at different times come to the farm in search of rats, of which they kill a vast number. My father gave orders that they should not be molested; after remaining, however, for some time, they invariably took their departure, for, as it may be supposed, it is impossible to detain them against their will, as they can climb over high palings or walls and insinuate their bodies into very small holes.
