"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."

"I didn't hear anything," said Gilbert. "Nor I," added Warley. "But my hearing is not nearly as good as Frank's. I've often noticed that."

"Let us stop and listen," suggested Charles.

They all stood still, intently listening. Presently a faint sound was wafted to them, apparently from a great distance--from the edge of the sandy desert, they fancied, which was still visible beyond the wooded tracts.

"No," said Charles, when the sound had been twice repeated, "that is not the cry of any animal, with which I am acquainted. It sounds more like a human voice than anything else. If it was at all likely that there was any other party of travellers in these parts, I should think they were hailing us. But nothing can be more improbable than that."

"Still it is possible," urged Warley, "and they may be in want of our help. Ought we not to go and find out the truth?"

"I think you are right, Ernest," said Frank.

"Well, I don't know," urged Gilbert, nervously. "I've heard all sorts of stories of voices being heard in the deserts, enticing people to their destruction, and it may be some ruse of the savages about here, who want to get us into their hands, to possess themselves of our guns.

What do you say, doctor?"

"Why, as for the voices, Nick, I've heard the stories you speak of, which have been told chiefly by persons who had lost their way and were nearly dead from cold and hunger. Under such circ.u.mstances, when people's nerves and senses begin to fail them, they fancy all sorts of strange things. No doubt, too, there are all sorts of acoustic deceptions in these wild regions, as there are optical delusions; but I don't think we four--all of us in sound health--are likely to be so deceived--"

"But how about the savages, doctor?" interposed Nick, anxiously.

"Well, if these were the backwoods of America, and we had the Red Indians to deal with, there would be a good deal in your suggestion.

But neither the Hottentots nor the Bushmen are given to stratagems of this kind. However, we'll move warily, and if any treachery is designed, we shall be pretty sure to baffle it."

They turned off in the direction whence the cry had come, keeping to the open ground, and giving a wide berth to any clump of trees or underwood which might harbour an enemy. Every now and then they paused to listen for the sound, which was regularly repeated, at intervals apparently of two or three minutes, and grew more distinct as they advanced. It was now certain that the cry was human, and sounded like that of a full-grown man.

"We are getting a good deal nearer," observed Warley, as they pa.s.sed the last patch of trees, and entered once more the sandy wilderness. "I should say we must be almost close, only I don't see any place where the person who is crying out in this manner can be hidden."

"It comes from that heap of stones there," exclaimed Frank, "that heap to the left, I mean--about two hundred yards further on."

"I see the stones, Frank, plain enough," said Mr Lavie, "but a man couldn't be hidden among them. You call it a heap of stones, but there is no heap. There is not so much as one lying upon another."

"Nevertheless the cry comes from there," said Warley; "I heard it the last time quite plainly. Let us go up and see."

They cautiously approached the spot in question, where there were about thirty or forty moderate-sized stones scattered on the plain. As they advanced the mysterious call was again heard.

"I see who it is that's making it," shouted Wilmore. "It's a fellow whose head is just above ground. I took his head for a black stone, with a lot of moss growing on it. But now I can see that it is a head, though the features are turned away from us."

They hurried up, and found that Frank was right. The stones were lying round what seemed to have been a dry well. In this a man had been buried up to his neck, the chin being just above the level of the ground. It did not appear that he was conscious of their approach; for at the interval of every two or three minutes he continued to give vent to the shrill monotonous cry, which had attracted their attention.

"What in the world can this mean!" exclaimed Nick. "The fellow can't have tumbled into the well, and the stones have fallen in after him, I suppose?"

"Is it some penance, do you think, that he is undergoing?" suggested Warley.

"Or a punishment for a crime he has committed?" said Wilmore.

"It may be a punishment for some offence," said Mr Lavie, "though I never heard of the Hottentots punishing their people in that way, and the man is plainly a Hottentot. As for anything else, of course it is quite impossible that he can have got jammed up in this way by accident; and the Hottentots know nothing of penances. Such a thing has never been heard of among them. But the first thing is to get the poor fellow out and give him something to restore him; for he is half dead with thirst and exposure to the sun, and does not seem conscious of what is pa.s.sing."

They fell to with a will, and had soon so far released the captive, that he was able to draw his breath freely and swallow a little brandy, which Mr Lavie poured on his tongue. He then opened his eyes for a moment, gazing with the utmost bewilderment and wonder on the dress and appearance of the figures round him; and then closed them again with a low groan.

"They meant this--the beggars that holed him in after this fashion,"

observed Frank. "The stones are fitted round him as carefully as though they had been building a wall. And, look! the poor wretch's arms are fastened by a thong to his sides. What brutes! Hand us the knife, Nick, and I'll cut them. How tough they are!"

It needed a strong hand and a sharp blade to sever the stout thongs, which on subsequent examination were found to consist of rhinoceros hide. But when his arms were at length free, the man made no effort to use them. It was evident that they were so benumbed by the forced restraint in which they had so long been kept, that he had lost all power over them. They were obliged to continue to remove the stones, until his feet were completely released, before he could be extricated from the hole; and when this was effected, it was only by the joint strength of the four Englishmen, the Hottentot himself being unable to render any a.s.sistance.

He was now carried to the shade of the nearest trees; Nick ran back to their recent resting-place, and returned with the iron pot full of water, while Warley and Wilmore, under the surgeon's direction, chafed his limbs. By the time of Gilbert's return their efforts had been successful. The sufferer once more opened his eyes, and making signs that the water should be handed to him, drank a long and refreshing draught. "He'll do now," observed Nick, as he witnessed this feat.

"There's no more fear for his health after that. But I should like to know who he is, and how he came there. I say, blacky, what may your name happen to be, and how did you come to be boxed up after that fashion, like a chimney-sweep stuck in a narrow flue?"

To the astonishment of the whole party, Nick's question was answered.

"Omatoko my name. Tank Englishman much for pull him out. Omatoko soon die, if they not come. Bushmen bury Omatoko one, two day ago. Good men, give Omatoko food, or he die now."

CHAPTER SEVEN.

A GOOD ACTION REWARDED--A RAID ON THE PARROTS--OMATOKO'S STORY--PROPOSED CHANGE OF ROUTE--BIVOUAC FOR THE NIGHT.

Nick started back at the unexpected reply. "Who'd have thought that?"

he exclaimed. "I should just as soon have expected to have heard Lion talk English."

"Well, it wasn't very good English," remarked Warley, "but it was as much to the purpose as if he had been Lindley Murray himself. I suppose the first thing is to comply with his request. I have got a biscuit in my pocket, which I brought away from the boat I dare say he can eat that."

"Not a doubt of it," said Nick; "and I guess he'll soon dispose of this slice of steinbok too. The worst of it is, that I had meant it for my own supper. But one can't let the poor wretch starve."

"We'll all contribute something," said the doctor, "and make him out a sufficient supper, I have no doubt. He mustn't eat very much at a time.

But the first thing is to carry him to some sheltered place, where we can make him up a comfortable bed. He must have a long rest before he will be good for anything."

"Carry him, hey!" cried Nick doubtfully, as he contemplated the prostrate figure of the Hottentot; who, for one of his race, was unusually tall and large of frame. "How are we to do that, I wonder?

He weighs twelve stone, I'll go bail for it, if he weighs an ounce, and we don't happen to have a horse and cart convenient."
