"Are there any large pythons in these parts?" asked Warley. "I've heard two quite different accounts. One says that they are never found so far south as this; the other, that they are to be met with thirty or forty feet long, and as thick round as a stout man. What is the truth of the matter?" "Well, the truth is something between the two, I believe, as is generally the case," said the surgeon. "They are certainly not common in Southern Africa, since people who have lived here all their lives have never seen one. But now and then they are to be met with. I know persons who have seen serpents' skins thirty feet long in the possession of natives; and one case I heard of, in which a skin was exhibited fully ten feet longer than that." "Are they difficult to kill?" asked Frank. "Not if you bide your time," said Lavie. "If you come upon them when they are hungry, they--the larger ones, that is--are more than a match for even the strongest men: and unless they are approached unawares, and wounded, so as to destroy their muscular power, a struggle with them would be most dangerous. But after they have gorged their prey, they are killed as easily as so many sheep--more easily in fact, for they are quite torpid." "What are the worst snakes found in these parts?" inquired Gilbert. "The cobra and the puff adder, I should say," returned the surgeon. "The first will spring at you as if it was discharged out of some engine, and with such force, that if it fails to strike its mark it will overshoot the spot by several feet. The natives call it the hair-serpent, and are in great terror of it. If no sufficient remedy is applied, its bite will cause death in less than an hour." "_Is_ there any sufficient remedy?" rejoined Nick. "I thought there was no cure." "It's not so bad as that, Nick. There are remedies for most bites--the cobra's for instance. There is a root which the mangoust always eats, when it feels itself bitten by a cobra, and which is, so far as is known, a complete cure. Eau de luce and sweet milk are generally given in this country for a snake's bite, and the natives have beans and serpent stones, which, it is said, effect a cure. But the best thing to do--what I should have done in your case, Nick, if you had been bitten-- is, first to fasten a ligature as tight as possible above the wounded part, and then cauterise or cut away the injured flesh. Snakes' bites are nasty things in these hot countries, and one can't be too careful. But come, it is time we move on again. We ought to reach the river banks early in the afternoon." They recommenced their march accordingly, and had proceeded half a mile or so further, when Frank suddenly called upon them to stop. "What can that noise be?" he said. "I have heard it two or three times in the course of the last few minutes. It doesn't sound like the cry of a bird, or beast either. And yet I suppose it must be."
