The Adventures of Captain Horn Part 7

"Man, since you have been in this part of the country, have you ever seen or heard of any wild beasts here? Are there any jaguars or pumas?"

The African shook his head. "No, no," said he, "no wild beasts. Everybody sleep out of doors. No think of beasts--no snakes."

The captain dropped his gun upon the ground. "Miss Markham!" he exclaimed. "Mrs. Cliff! I truly believe we are out of all danger--that we--"

But the two ladies had gone inside, and heard him not. They appreciated to the full the danger from which they had been delivered. Ralph, too, had gone. The captain saw him on his post of observation, jamming the end of his flagpole down between two rocks.

"h.e.l.lo!" cried the boy, seeing the captain looking up at him, "we might as well have this flying here all the time. There is n.o.body to hurt us now, and we want people to know where we are."

The captain walked by the little group of Africans, who were sitting on the ground, talking in their native tongue, and entered the pa.s.sage. He climbed over the barrier, and went to the lake. He did not wish to talk to anybody, but he felt that he must do something, and now was a good time to carry out his previous intention to cross over the empty bed of the lake and to look out of the opening on the other side. There was no need now to do this for purposes of vigilance, but he thought that if he could get out on the other side of the cave he might discover some clew to the disappearance of the lake.

He had nearly crossed the lake bottom, when suddenly he stopped, gazing at something which stood before him, and which was doubtless the object he had struck when swimming. The sun was now high and the cave well lighted, and with a most eager interest the captain examined the slimy and curious object on which his feet had rested when it was submerged, and from which he had fallen. It was not the horizontal trunk of a tree with a branch projecting from it at right angles. It was nothing that was natural or had grown. It was plainly the work of man. It was a machine.

At first the captain thought it was made of wood, but afterwards he believed it to be of metal of some sort. The horizontal portion of it was a great cylinder, so near the bottom of the lake that he could almost touch it with his hands, and it was supported by a ma.s.sive framework. Prom this projected a long limb or bar, which was now almost horizontal, but which the captain believed to be the thick rod which had stood upright when he clutched it, and which had yielded to his weight and had gone down with him. He knew now what it was: it was a handle that had turned.

He hurried to the other end of the huge machine, where it rested against the rocky wall of the cavern. There he saw in the shadow, but plain enough now that he was near it, a circular aperture, a yard or more in diameter. Inside of this was something which looked like a solid wheel, very thick, and standing upright in the opening. It was a valve. The captain stepped back and gazed for some minutes at this great machine which the disappearance of the water had revealed. It was easy for him to comprehend it now.

"When I slipped and sank," he said to himself, "I pulled down that lever, and I opened the water-gate and let out the lake."

The captain was a man whose mind was perfectly capable of appreciating novel and strange impressions, but with him such impressions always connected themselves, in one way or another, with action: he could not stand and wonder at the wonderful which had happened--it always suggested something he must do. What he now wanted to do was to climb up to the great aperture which lighted the cavern, and see what was outside. He could not understand how the lake could have gone from its basin without the sound of the rus.h.i.+ng waters being heard by any one of the party.

With some difficulty, he climbed up to the cleft and got outside. Here he had a much better view of the topography of the place than he had yet been able to obtain. So far as he had explored, his view toward the interior of the country had been impeded by rocks and hills. Here he had a clear view from the mountains to the sea, and the ridge which he had before seen to the southward he could now examine to greater advantage.

It was this long chain of rocks which had concealed them from their enemies, and on the other side of which must be the ravine in which the Rackbirds had made their camp.

Immediately below the captain was a little gorge, not very deep nor wide, and from its general trend toward the east and south the captain was sure that it formed the upper part of the ravine of the Rackbirds. At the bottom of it there trickled a little stream. To the northeast ran another line of low rock, which lost itself in the distance before it blended into the mountains, and at the foot of this must run the stream which had fed the lake.

In their search for water, game, or fellow-beings, no one had climbed these desolate rocks, apparently dry and barren. But still the captain was puzzled as to the way the water had gone out of the lake. He did not believe that it had flowed through the ravine below. There were no signs that there had been a flood down there. Little vines and plants were growing in c.h.i.n.ks of the rocks close to the water. And, moreover, had a vast deluge rushed out almost beneath the opening which lighted the cave, it must have been heard by some of the party. He concluded, therefore, that the water had escaped through a subterranean channel below the rocks from which he looked down.

He climbed down the sides of the gorge, and walked along its bottom for two or three hundred yards, until around a jutting point of rock he saw that the sides of the defile separated for a considerable distance, and then, coming together again below, formed a sort of amphitheatre. The bottom of this was a considerable distance below him, and he did not descend into it, but he saw plainly that it had recently contained water, for pools and puddles were to be seen everywhere.

At the other end of it, where the rocks again approached each other, was probably a precipice. After a few minutes' cogitation, Captain Horn felt sure that he understood the whole matter: a subway from the lake led to this amphitheatre, and thus there had been no audible rush of the waters until they reached this point, where they poured in and filled this great basin, the lower end of which was probably stopped up by acc.u.mulations of sand and deposits, which even in that country of scant vegetation had acc.u.mulated in the course of years. When the waters of the lake had rushed into the amphitheatre, this natural dam had held them for a while, but then, giving way before the great pressure, the whole body of water had suddenly rushed down the ravine to the sea.

"Yes," said the captain, "now I understand how it happened that although I opened the valve at noon, the water did not reach the Rackbirds until some hours later, and then it came suddenly and all at once, which would not have been the case had it flowed steadily from the beginning through the outlet made for it."

When the captain had returned and reported his discoveries, and he and his party had finished their noonday meal, which they ate outside on the plateau, with the fire burning and six servants to wait on them, Mrs.

Cliff said:

"And now, captain, what are we going to do? Now that our danger is past, I suppose the best thing for us is to stay here in quiet and thankfulness, and wait for Mr. Rynders. But, with the provisions we have, we can't wait very long. When there were but five of us, we might have made the food hold out for a day or two longer, but now that we are ten, we shall soon be without anything to eat."

"I have been talking to Maka about that," said the captain, "and he says that Cheditafa reports all sorts of necessary things in the Rackbirds'

storehouse, and he proposes that he and the rest of the black fellows go down there and bring us some supplies. They are used to carrying these stores, and six of them can bring us enough to last a good while. Now that everything is safe over there, I can see that Maka is very anxious to go, and, in fact, I would like to go myself. But although there doesn't seem to be any danger at present, I do not want to leave you."

"As for me," said Miss Markham, "I want to go there. There is nothing I like better than exploring."

"That's to my taste, too," said the captain, "but it will be better for us to wait here and see what Maka has to say when he gets back. Perhaps, if Mr. Rynders doesn't turn up pretty soon, we will all make a trip down there. Where is Ralph? I don't want him to go with the men."

"He is up there on his lookout, as he calls it," said his sister, "with his spy-gla.s.s."

"Very good," said the captain. "I will send the men off immediately. Maka wants to go now, and they can come back by the light of the young moon.

When they have loads to carry, they like to travel at night. We shall have to get our own supper, and that will give Ralph something to do."

The party of Africans had not gone half-way from the plateau to the beach before they were discovered by the boy on the outlook rock, and he came rus.h.i.+ng down to report that the darkies were running away. When he was told the business on which they had gone, he was very much disappointed that he was not allowed to go with them, and, considerably out of temper, retired to his post of observation, where, as it appeared, he was dividing his time between the discovery of distant specks on the horizon line of the ocean and imaginary jaguars and pumas on the foot-hills.

CHAPTER XI

A NEW HEMISPHERE

With a tin pail in his hand, the captain now went to the cavern of the lake. He wished very much to procure some better water than the last that had been brought, and which Mok must have dipped up from a very shallow puddle. It was possible, the captain thought, that by going farther into the cavern he might find a deeper pool in which water still stood, and if he could not do this, he could get water from the little stream in the ravine. More than this, the captain wished very much to take another look at the machine by which he had let out the water. His mind had been so thoroughly charged with the sense of danger that, until this had faded away, he had not been able to take the interest in the artificial character of the lake which it deserved.

As the captain advanced into the dimmer recesses of the cavern, he soon found a pool of water a foot or more in depth, and having filled his pail at this, he set it down and walked on to see what was beyond. His eyes having now conformed themselves to the duskiness of the place, he saw that the cavern soon made a turn to the left, and gazing beyond him, he judged that the cave was very much wider here, and he also thought that the roof was higher. But he did not pay much attention to the dimensions of the cavern, for he began to discern, at first dimly and then quite plainly, a large object which rose from the bottom of the basin. He advanced eagerly, peering at what seemed to be a sort of dome--like formation of a lighter color than the rocks about him, and apparently about ten feet high.

Carefully feeling his way for fear of pitfalls, the captain drew close to the object, and placed his hand upon it. He believed it to be of stone, and moving his hand over it, he thought he could feel joints of masonry.

It was clearly a structure built by men. Captain Horn searched his pockets for a match, but found none, and he hastened back to the cave to get the lantern, pa.s.sing, without noticing it, the pail which he had filled with water. He would have brought the lantern with him when he first came, but they had no oil except what it contained, and this they had husbanded for emergencies. But now the captain wanted light--he cared not what might happen afterwards. In a very short time, with the lantern in his hand, which lighted up the cave for a considerable distance about him, the captain again stood at the foot of the subterranean dome.

He walked around it. He raised and lowered his lantern, and examined it from top to bottom. It was one half a sphere of masonry, built in a most careful manner, and, to all appearances, as solid as a great stone ball, half sunken in the ground. Its surface was smooth, excepting for two lines of protuberances, each a few inches in height, and about a foot from each other. These rows of little humps were on opposite sides of the dome, and from the bottom nearly to the top. It was plain they were intended to serve as rude ladders by which the top of the mound could be gained.

The captain stepped back, held up his lantern, and gazed in every direction. He could now see the roof of the cavern, and immediately above him he perceived what he was sure were regular joints of masonry, but on the sides of the cave he saw nothing of the sort. For some minutes he stood and reflected, his brain in a whirl. Presently he exclaimed:

"Yes, this cave is man's work! I am sure of it. It is not natural. I wondered how there could be such a cave on the top of a hill. It was originally a gorge, and they have roofed it over, and the bottom of the basin has been cut out to make it deeper. It was made so that it could be filled up with water, and roofed over so that n.o.body should know there was any water here, unless they came on it by means of the pa.s.sage from our caves. That pa.s.sage must have been blocked up. As for the great opening in the side of the cave, the rocks have fallen in there--that is easy enough to see. Yes, men made this cave and filled it with water, and if the water were high enough to cover the handle of that machine, as it was when I struck it, it must also have been high enough to cover up this stone mound. The lake was intended to cover and hide that mound. And then, to make the hiding of it doubly sure, the men who built all this totally covered up the lake so that n.o.body would know it was here. And then they built that valve apparatus, which was also submerged, so that they could let out the water when they wanted to get at this stone thing, whatever it is. What a scheme to hide anything! Even if anybody discovered the lake, which would not be likely until some part of the cave fell in, they would not know it was anything but a lake when they did see it. And as for letting off the water, n.o.body but the people who knew about it could possibly do that, unless somebody was fool enough to take the cold bath I was obliged to take, and even then it would have been one chance in a hundred that he found the lever, and would know how to turn it when he did find it. This whole thing is the work of the ancient South Americans, and I imagine that this stone mound is the tomb of one of their kings."

At this moment the captain heard something, and turned to listen. It was a voice--the voice of a boy. It was Ralph calling to him. Instantly the captain turned and hurried away, and as he went he extinguished his lantern. When he reached his pail of water he picked it up, and was very soon joined by Ralph, who was coming to meet him over the bottom of the lake.

"I have been looking for you everywhere, captain," said he. "What have you been after? More water? And you took a lantern to find it, eh? And you have been ever so far into the cave. Why didn't you call me? Let me have the lantern. I want to go to explore."

But the captain did not give him the lantern, nor did he allow him to go to explore.

"No, sir," said he. "What we've got to do is to hurry outside and help get supper. We must wait on ourselves to-night."

When supper was over, that evening, and the little party was sitting out on the plateau, gazing over the ocean at the sunlit sky, Mrs. Cliff declared that she wished they could bring their bedding and spread it on the ground out there, and sleep.

"It is dry enough," she said, "and warm enough, and if there is really nothing to fear from animals or men, I don't want ever to go inside of those caves again. I had such horrible fears and ideas when I was sitting trembling in those dismal vaults, expecting a horde of human devils to burst in upon us at any moment, that the whole place is horrible to me. Anyway, if I knew that I had to be killed, I would rather be killed out here."

The captain smiled. "I don't think we will give up the caves just yet. I, for one, most certainly want to go in there again." And then he told the story of the stone mound which he had discovered.

"And you believe," cried Mrs. Cliff, leaning forward, "that it is really the tomb of an ancient king?"

"If it isn't that, I don't know what it can be," said the captain.

"The grave of a king!" cried Ralph. "A mummy! With inscriptions and paintings! Oh, captain, let's go open it this minute, before those blackies get back."

The captain shook his head. "Don't be in such a hurry," he said. "It will not be an easy job to open that mound, and we shall need the help of the blackies, as you call them, if we do it at all."

"Do it at all!" cried Ralph. "I'll never leave this place until I do it myself, if there is n.o.body else to help."
