the morning after the departure of the boat, captain horn, in company with the englishman davis, each armed with a gun, set out on a tour of investigation, hoping to be able to ascend the rocky hills at the back of the camp, and find some elevated point commanding a view over the ocean. after a good deal of hard climbing they reached such a point, but the captain found that the main object was really out of his reach. he could now plainly see that a high rocky point to the southward, which stretched some distance out to sea, would cut off all view of the approach of rescuers coming from that direction, until they were within a mile or two of his landing-place. back from the sea the hills grew higher, until they blended into the lofty stretches of the andes, this being one of the few points where the hilly country extends to the ocean.
the coast to the north curved a little oceanward, so that a much more extended view could be had in that direction, but as far as he could see by means of a little pocket-glass which the boy ralph had lent him, the captain could discover no signs of habitation, and in this direction the land seemed to be a flat desert. when he returned to camp, about noon, he had made up his mind that the proper thing to do was to make himself and his companions as comfortable as possible and patiently await the return of his mate with succor.
captain horn was very well satisfied with his present place of encampment. although rain is unknown in this western portion of peru, which is, therefore, in general desolate and barren, there are parts of the country that are irrigated by streams which flow from the snow-capped peaks of the andes, and one of these fertile spots the captain seemed to have happened upon. on the plateau there grew a few bushes, while the face of the rock in places was entirely covered by hanging vines. this fertility greatly puzzled captain horn, for nowhere was to be seen any stream of water, or signs of there ever having been any. but they had with them water enough to last for several days, and provisions for a much longer time, and the captain felt little concern on this account.
as for lodgings, there were none excepting the small tent which he had put up for the ladies, but a few nights in the open air in that dry climate would not hurt the male portion of the party.
in the course of the afternoon, the two american sailors came to captain horn and asked permission to go to look for game. the captain had small hopes of their finding anything suitable for food, but feeling sure that if they should be successful, every one would be glad of a little fresh meat, he gave his permission, at the same time requesting the men to do their best in the way of observation, if they should get up high enough to survey the country, and discover some signs of habitation, if such existed in that barren region. it would be a great relief to the captain to feel that there was some spot of refuge to which, by land or water, his party might make its way in case the water and provisions gave out before the return of the mate.
as to the men who went off in the boat, the captain expected to see but a few of them again. one or two might return with the mate, in such vessel as he should obtain in which to come for them, but the most of them, if they reached a seaport, would scatter, after the manner of seamen.
the two sailors departed, promising, if they could not bring back fish or fowl, to return before dark, with a report of the lay of the land.
it was very well that maka did not have to depend on these hunters for the evening meal, for night came without them, and the next morning they had not returned. the captain was very much troubled. the men must be lost, or they had met with some accident. there could be no other reason for their continued absence. they had each a gun, and plenty of powder and shot, but they had taken only provisions enough for a single meal.
davis offered to go up the hills to look for the missing men. he had lived for some years in the bush in australia, and he thought that there was a good chance of his discovering their tracks. but the captain shook his head.
"you are just as likely to get lost, or to fall over a rock, as anybody else," he said, "and it is better to have two men lost than three. but there is one thing that you can do. you can go down to the beach, and make your way southward as far as possible. there you can find your way back, and if you take a gun, and fire it every now and then, you may attract the attention of shirley and burke, if they are on the hills above, and perhaps they may even be able to see you as you walk along. if they are alive, they will probably see or hear you, and fire in answer. it is a very strange thing that we have not heard a shot from them."
ralph begged to accompany the englishman, for he was getting very restless, and longed for a ramble and scramble. but neither the captain nor his sister would consent to this, and davis started off alone.
"if you can round the point down there," said the captain to him, "do it, for you may see a town or houses not far away on the other side. but don't take any risks. at all events, make your calculations so that you will be back here before dark."
the captain and ralph assisted the two ladies to a ledge of rock near the camp from which they could watch the englishman on his way. they saw him reach the beach, and after going on a short distance he fired his gun, after which he pressed forward, now and then stopping to fire again. even from their inconsiderable elevation they could see him until he must have been more than a mile away, and he soon after vanished from their view.
as on the previous day darkness came without the two american sailors, so now it came without the englishman, and in the morning he had not returned. of course, every mind was filled with anxiety in regard to the three sailors, but captain horn's soul was racked with apprehensions of which he did not speak. the conviction forced itself upon him that the men had been killed by wild beasts. he could imagine no other reason why davis should not have returned. he had been ordered not to leave the beach, and, therefore, could not lose his way. he was a wary, careful man, used to exploring rough country, and he was not likely to take any chances of disabling himself by a fall while on such an expedition.
although he knew that the great jaguar was found in peru, as well as the puma and black bear, the captain had not supposed it likely that any of these creatures frequented the barren western slopes of the mountains, but he now reflected that there were lions in the deserts of africa, and that the beasts of prey in south america might also be found in its deserts.
a great responsibility now rested upon captain horn. he was the only man left in camp who could be depended upon as a defender,—for maka was known to be a coward, and ralph was only a boy,—and it was with a shrinking of the heart that he asked himself what would be the consequences if a couple of jaguars or other ferocious beasts were to appear upon that unprotected plateau in the night, or even in the daytime. he had two guns, but he was only one man. these thoughts were not cheerful, but the captain's face showed no signs of alarm, or even unusual anxiety, and, with a smile on his handsome brown countenance, he bade the ladies good morning as if he were saluting them upon a quarter-deck.
"i have been thinking all night about those three men," said miss markham, "and i have imagined something which may have happened. isn't it possible that they may have discovered at a distance some inland settlement which could not be seen by the party in the boat, and that they thought it their duty to push their way to it, and so get assistance for us? in that case, you know, they would probably be a long time coming back."
"that is possible," said the captain, glad to hear a hopeful supposition, but in his heart he had no faith in it whatever. if davis had seen a village, or even a house, he would have come back to report it, and if the others had found human habitation, they would have had ample time to return, either by land or by sea.
the restless ralph, who had chafed a good deal because he had not been allowed to leave the plateau in search of adventure, now found a vent for his surplus energy, for the captain appointed him fire-maker. the camp fuel was not abundant, consisting of nothing but some dead branches and twigs from the few bushes in the neighborhood. these ralph collected with great energy, and maka had nothing to complain of in regard to fuel for his cooking.
toward the end of that afternoon, ralph prepared to make a fire for the supper, and he determined to change the position of the fireplace and bring it nearer the rocks, where he thought it would burn better. it did burn better—so well, indeed, that some of the dry leaves of the vines that there covered the face of the rocks took fire. ralph watched with interest the dry leaves blaze and the green ones splutter, and then he thought it would be a pity to scorch those vines, which were among the few green things about them, and he tried to put out the fire. but this he could not do, and, when he called maka, the negro was not able to help him. the fire had worked its way back of the green vines, and seemed to have found good fuel, for it was soon crackling away at a great rate, attracting the rest of the party.
"can't we put it out?" cried miss markham. "it is a pity to ruin those beautiful vines."
the captain smiled and shook his head. "we cannot waste our valuable water on that conflagration," said he. "there is probably a great mass of dead vines behind the green outside. how it crackles and roars! that dead stuff must be several feet thick. all we can do is to let it burn. it cannot hurt us. it cannot reach your tent, for there are no vines over there."
the fire continued to roar and blaze, and to leap up the face of the rock.
"it is wonderful," said mrs. cliff, "to think how those vines must have been growing and dying, and new ones growing and dying, year after year, nobody knows how many ages."
"what is most wonderful to me," said the captain, "is that the vines ever grew there at all, or that these bushes should be here. nothing can grow in this region, unless it is watered by a stream from the mountains, and there is no stream here."
miss markham was about to offer a supposition to the effect that perhaps the precipitous wall of rock which surrounded the little plateau, and shielded it from the eastern sun, might have had a good effect upon the vegetation, when suddenly ralph, who had a ship's biscuit on the end of a sharp stick, and was toasting it in the embers of a portion of the burnt vines, sprang back with a shout.
"look out!" he cried. "the whole thing's coming down!" and, sure enough, in a moment a large portion of the vines, which had been clinging to the rock, fell upon the ground in a burning mass. a cloud of smoke and dust arose, and when it had cleared away the captain and his party saw upon the perpendicular side of the rock, which was now revealed to them as if a veil had been torn away from in front of it, an enormous face cut out of the solid stone.
