Groot Willem was at length within range, and was about to level his roer on the game, when the movements of the little animal caused him to hold his hand. Its actions were very odd, indeed. It was not browsing—it was not standing still—it was not running away from the ground,—and yet it was in constant motion!
As already stated, it was close in to the edge of the timber, where a number of small olean trees stood thinly over the ground. In front of these the little buck was dancing about in a very original manner. Now it ran to the right,—anon to the left,—now zigzag,—now it started suddenly backwards,—then ran forwards again,—all the while its eyes turning in a particular direction and shining brilliantly, as if the animal itself was in a state of unusual excitement.
Groot Willem looked to discover the cause of this odd manoeuvring on the part of the steenbok; something among the olean-wood trees seemed to attract the notice of the animal. On this something the eyes of the hunter rested with wonderment; and for some moments he was unable to make out what it was. He could perceive a large glittering mass near the bottom of one of the trees; but this mass at first sight appeared without any particular form, and lay perfectly motionless.
As Groot Willem continued to gaze upon it, however, it gradually assumed a form, or rather his eyes gradually traced one, for the mass had not yet moved.
A hideous form it was—though of smooth and regular proportions—it was the form of a reptile—a serpent!
A serpent of enormous size, for the mass of its body, gathered up in a sort of irregular coil, covered the ground over a space of several square feet, while the body itself seemed thicker than the thighs of a full-grown man! The head of the reptile rested upon the top of the coiled body, and on running his eye along the mottled and glistening outlines, Groot Willem perceived that its tail was doubled around the stem of the olean-wood, and held it with firm grasp—for the serpent belonged to a family whose tails are furnished with horny claw-like hooks, giving them a power of prehension in this member equal to that of a hand. This is the family of the Boidae, or “boas,” to which the one in question was generically related. It was a python—the Python Natalensis.
Groot Willem only knew it as the “rock-snake,” and that is its ordinary designation—given it on account of the fact of its being a dweller among rocks and stony places. It might very properly be called “rock-boa,” which would distinguish it from its cousins of America, the Anaconda, or “water-boa,” and the true boa, which is a denizen of the forest, and which would therefore merit the title of “tree-boa.”
Notwithstanding the difference of the dwelling-place of the boas and pythons, their habits are very similar. They lie in wait for their prey, capture it with their strong retractile teeth, and crushing it to death by constriction, swallow it whole—though often the animal swallowed is much larger than the diameter of their own bodies. Their elastic muscles, however, enable them to effect their purpose, aided by the slippery saliva which is copiously supplied from their glands.
When Groot Willem first saw the huge python, its head was lying over the coils of its body, and motionless. Presently, the head was raised up with the neck, and several feet of the body; and the parts, thus erected, moved gently from side to side with a sort of vibratory motion. The jaws were widely extended, so that the sharp retractile teeth were plainly visible, and the forked tongue at intervals was shot forward, and gleamed in the sun. The eyes of the reptile sparkled like fire.
It was a fearful object to look upon! And yet the steenbok did not appear to dread it. On the contrary, it kept drawing nearer and nearer, excited either by curiosity or fascination!
