four days had passed, and nothing had happened. the stone mound in the lake had not been visited, for there had been no reason for sending the black men away, and with one of them nearer than a mile the captain would not even look at his treasure. there was no danger that they would discover the mound, for they were not allowed to take the lantern, and no one of them would care to wander into the dark, sombre depths of the cavern without a light.
the four white people, who, with a fair habitation in the rocks, with plenty of plain food to eat, with six servants to wait on them, and a climate which was continuously delightful, except in the middle of the day, and with all fear of danger from man or beast removed from their minds, would have been content to remain here a week or two longer and await the arrival of a vessel to take them away, were now in a restless and impatient condition of mind. they were all eager to escape from the place. three of them longed for the return of rynders, but the other one steadily hoped that they might get away before his men came back.
how to do this, or how to take with him the treasure of the incas, was a puzzling question with which the captain racked his brains by day and by night. at last he bethought himself of the rackbirds' vessel. he remembered that maka had told him that provisions were brought to them by a vessel, and there was every reason to suppose that when these miscreants went on some of their marauding expeditions they travelled by sea. day by day he had thought that he would go and visit the rackbirds' storehouse and the neighborhood thereabout, but day by day he had been afraid that in his absence rynders might arrive, and when he came he wanted to be there to meet him.
but now the idea of the boat made him brave this possible contingency, and early one morning, with cheditafa and two other of the black fellows, he set off along the beach for the mouth of the little stream which, rising somewhere in the mountains, ran down to the cavern where it had once widened and deepened into a lake, and then through the ravine of the rackbirds on to the sea. when he reached his destination, captain horn saw a great deal to interest him.
just beyond the second ridge of rock which maka had discovered, the stream ran into a little bay, and the shores near its mouth showed evident signs that they had recently been washed by a flood. on points of rock and against the sides of the sand mounds, he saw bits of debris from the rackbirds' camp. here were sticks which had formed the timbers of their huts; there were pieces of clothing and cooking-utensils; and here and there, partly buried by the shifting sands, were seen the bodies of rackbirds, already desiccated by the dry air and the hot sun of the region. but the captain saw no vessel.
"dat up here," said cheditafa. "dey hide dat well. come 'long, captain."
following his black guide, the captain skirted a little promontory of rocks, and behind it found a cove in which, well concealed, lay the rackbirds' vessel. it was a sloop of about twenty tons, and from the ocean, or even from the beach, it could not be seen. but as the captain stood and gazed upon this craft his heart sank. it had no masts nor sails, and it was a vessel that could not be propelled by oars.
wading through the shallow water,—for it was now low tide,—the captain climbed on board. the deck was bare, without a sign of spar or sail, and when, with cheditafa's help, he had forced the entrance of the little companionway, and had gone below, he found that the vessel had been entirely stripped of everything that could be carried away, and when he went on deck again he saw that even the rudder had been unshipped and removed. cheditafa could give him no information upon this state of things, but after a little while captain horn imagined the cause for this dismantled condition of the sloop. the rackbirds' captain could not trust his men, he said to himself, and he made it impossible for any of them to escape or set out on an expedition for themselves. it was likely that the masts and sails had been carried up to the camp, from which place it would have been impossible to remove them without the leader knowing it.
when he spoke to cheditafa on the subject, the negro told him that after the little ship came in from one of its voyages he and his companions had always carried the masts, sails, and a lot of other things up to the camp. but there was nothing of the sort there now. every spar and sail must have been carried out to sea by the flood, for if they had been left on the shores of the stream the captain would have seen them.
this was hard lines for captain horn. if the rackbirds' vessel had been in sailing condition, everything would have been very simple and easy for him. he could have taken on board not only his own party, but a large portion of the treasure, and could have sailed away as free as a bird, without reference to the return of rynders and his men. a note tied to a pole set up in a conspicuous place on the beach would have informed mr. rynders of their escape from the place, and it was not likely that any of the party would have thought it worth while to go farther on shore. but it was of no use to think of getting away in this vessel. in its present condition it was absolutely useless.
while the captain had been thinking and considering the matter, cheditafa had been wandering about the coast exploring. presently captain horn saw him running toward him, accompanied by the two other negroes.
"'nother boat over there," cried cheditafa, as the captain approached him,—"'nother boat, but badder than this. no good. cook with it, that's all."
the captain followed cheditafa across the little stream, and a hundred yards or so along the shore, and over out of reach of the tide, piled against a low sand mound, he saw a quantity of wood, all broken into small pieces, and apparently prepared, as cheditafa had suggested, for cooking-fires. it was also easy to see that these pieces of wood had once been part of a boat, perhaps of a wreck thrown up on shore. the captain approached the pile of wood and picked up some of the pieces. as he held in his hand a bit of gunwale, not much more than a foot in length, his eyes began to glisten and his breath came quickly. hastily pulling out several pieces from the mass of debris, he examined them thoroughly. then he stepped back, and let the piece of rudder he was holding drop to the sand.
"cheditafa," said he, speaking huskily, "this is one of the castor's boats. this is a piece of the boat in which rynders and the men set out."
the negro looked at the captain and seemed frightened by the expression on his face. for a moment he did not speak, and then in a trembling voice he asked, "where all them now?"
the captain shook his head, but said nothing. that pile of fragments was telling him a tale which gradually became plainer and plainer to him, and which he believed as if rynders himself had been telling it to him. his ship's boat, with its eight occupants, had never gone farther south than the mouth of the little stream. that they had been driven on shore by the stress of weather the captain did not believe. there had been no high winds or storms since their departure. most likely they had been induced to land by seeing some of the rackbirds on shore, and they had naturally rowed into the little cove, for assistance from their fellow-beings was what they were in search of. but no matter how they happened to land, the rackbirds would never let them go away again to carry news of the whereabouts of their camp. almost unarmed, these sailors must have fallen easy victims to the rackbirds.
it was not unlikely that the men had been shot down from ambush without having had any intercourse or conversation with the cruel monsters to whom they had come to seek relief, for had there been any talk between them, rynders would have told of his companions left on shore, and these would have been speedily visited by the desperadoes. for the destruction of the boat there was reason enough: the captain of the rackbirds gave his men no chance to get away from him.
with a heart of lead, captain horn turned to look at his negro companions, and saw them all sitting together on the sands, chattering earnestly, and holding up their hands with one or more fingers extended, as if they were counting. cheditafa came forward.
"when all your men go away from you?" he asked.
the captain reflected a moment, and then answered, "about two weeks ago."
"that's right! that's right!" exclaimed the negro, nodding violently as he spoke. "we talk about that. we count days. it's just ten days and three days, and rackbirds go 'way, and leave us high up in rock-hole, with no ladder. after a while we hear guns, guns, guns. long time guns shooting. when they come back, it almost dark, and they want supper bad. all time they eat supper, they talk 'bout shooting sharks. shot lots sharks, and chuck them into the water. sharks in water already before they is shot. we say then it no sharks they shot. now we say it must been—"
the captain turned away. he did not want to hear any more. there was no possible escape from the belief that rynders and all his men had been shot down, and robbed, if they had anything worth taking, and then their bodies carried out to sea, most likely in their own boat, and thrown overboard.
there was nothing more at this dreadful place that captain horn wished to see, to consider, or to do, and calling the negroes to follow him, he set out on his return.
during the dreary walk along the beach the captain's depression of spirits was increased by the recollection of his thoughts about the sailors and the treasure. he had hoped that these men would not come back in time to interfere with his disposal, in his own way, of the gold he had found. they would not come back now, but the thought did not lighten his heart. but before he reached the caves, he had determined to throw off the gloom and sadness which had come upon him. under the circumstances, grief for what had happened was out of place. he must keep up a good heart, and help his companions to keep up good hearts. now he must do something, and, like a soldier in battle, he must not think of the comrade who had fallen beside him, but of the enemy in front of him.
when he reached the caves he found supper ready, and that evening he said nothing to his companions of the important discoveries he had made, contenting himself with a general statement of the proofs that the rackbirds and their camp had been utterly destroyed by the flood.
