coming in that direction, I know he will give very quick warning. I hardly think, though, that they would trust themselves to be picked off while swimming."
"And you?" said she.
"Oh, I shall keep my eyes on all points," said he, "as far as I can. I begin to feel a spirit of fight rising up within me. If I thought I could keep them off until Rynders gets here, I almost wish they would then come. I would like to kill a lot of them."
"Suppose," said Edna Markham, after a moment's reflection, "that they should see Mr. Rynders coming back, and should attack him."
"I hardly think they would do that," replied the captain. "He will probably come in a good-sized vessel, and I don't think they are the kind of men for open battle. They are midnight sneaks and assassins. Now, I advise all of you to go and get something to eat. It would be better for us not to try to do any cooking, and so make a smoke."
The captain did not wish to talk any more. Miss Markham's last remark had put a new fear into his mind. Suppose the Rackbirds had lured Rynders and his men on shore? Those sailors had but few arms among them. They had not thought, when they left, that there would be any necessity for defence against their fellow-beings.
When Edna Markham told Mrs. Cliff what the captain had said about their chances, and what he intended to do for their protection, the older woman brightened up a good deal.
"I have great faith in the captain," she declared, "and if he thinks it is worth while to make a fight, I believe he will make a good one. If they should be firing, and Mr. Rynders is approaching the coast, even if it should be night, he would lose no time in getting to us."
Toward the close of that afternoon three wild beasts came around the point of the bluff and made their way northward along the beach. They were ferocious creatures with shaggy hair and beards. Two of them carried guns, and each of them had a knife in his belt. When they came to a broad bit of beach above the reach of the waves, they were very much surprised at some footsteps they saw. They were the tracks of two men, instead of those of the one they were looking for. This discovery made them very cautious. They were eager to kill the escaped African before he got far enough away to give information of their retreat, for they knew not at what time an armed force in search of them might approach the coast. But they were very wary about running into danger. There was somebody with that black fellow—somebody who wore boots.
After a time they came to the boat. The minute they saw this, each miscreant crouched suddenly upon the sand, and, with cocked guns, they listened. Then, hearing nothing, they carefully examined the boat. It was empty—there were not even oars in it.
Looking about them, they saw a hollow behind some rocks. To this they ran, crouching close to the ground, and there they sat and consulted.
It was between two and three o'clock the next morning that Maka's eyes, which had not closed for more than twenty hours, refused to keep open any longer, and with his head on the hard, rocky ground of the passage in which he lay, the poor African slept soundly. On the shelf at the edge of the lake, the other African, Mok, sat crouched on his heels, his eyes wide open. Whether he was asleep or not it would have been difficult to determine, but if any one had appeared in the great cleft on the other side of the lake, he would have sprung to his feet with a yell—his fear of the Rackbirds was always awake.
Inside the first apartment was Captain Horn, fast asleep, his two guns by his side. He had kept watch until an hour before, but Ralph had insisted upon taking his turn, and, as the captain knew he could not keep awake always, he allowed the boy to take a short watch. But now Ralph was leaning back against one of the walls, snoring evenly and steadily. In the next room sat Edna Markham, wide awake. She knew of the arrangement made with Ralph, and she knew the boy's healthy, sleepy nature, so that when he went on watch she went on watch.
Outside of the cave were three wild beasts. One of them was crouching on the farther end of the plateau. Another, on the lower ground a little below, stood, gun in hand, and barely visible in the starlight. A third, barefooted, and in garments dingy as the night, and armed only with a knife, crept softly toward the entrance of the cave. There he stopped and listened. He could plainly hear the breathing of the sleepers. He tried to separate these sounds one from another, so that he should be able to determine how many persons were sleeping inside, but this he could not do. Then his cat-like eyes, becoming more and more accustomed to the darkness within the entrance, saw the round head of Maka close upon the ground.
The soul of the listening fiend laughed within him. "Pretty watchers they are," he said to himself. "Not three hours after midnight, and they are all snoring!" Then, as stealthily and as slowly as he had come, he slipped away, and joining the others, they all glided through the darkness down to the beach, and then set off at their best speed back to their rendezvous.
After they had discovered that there were people in the cave, they had not thought of entering. They were not fully armed, and they did not know how many persons were inside. But they knew one thing, and that was that these shipwrecked people—for that was what they must be—kept a very poor watch, and if the whole band came on the following night, the affair would probably be settled with but very little trouble, no matter how large the party in the cave might be. It was not necessary to look any further for the escaped negro. Of course, he had been picked up by these people.
The three beasts reached their camp about daybreak, and everybody was soon awakened and the tale was told.
"It is a comfort," said the leader, lighting the stump of a black pipe which he thrust under his great mustache, and speaking in his native tongue, which some of them understood, and others did not, "to know that to-night's work is all cut out for us. Now we can take it easy to-day, and rest our bones. The order of the day is to keep close. No straggling, nor wandering. Keep those four niggers up in the pigeonhole. We will do our own cooking to-day, for we can't afford to run after any more of them. Lucky the fellow who got away can't speak English, for he can't tell anything about us, any more than if he was an ape. So snooze to-day, if you want to. I will give you work to do for to-night."
CHAPTER VII
GONE!
That morning, when the party in the cavern had had their breakfast, with some hot tea made on a spiritlamp which Mrs. Cliff had brought, and had looked cautiously out at the sunlit landscape, and the sea beyond, without seeing any signs or hearing any sound of wicked men, there came a feeling of relief. There was, indeed, no great ground for such a feeling, but as the Rackbirds had not come the day before nor during the night, perhaps they would not come at all. It might be they did not care whether the black man ran away or not. But Captain Horn did not relax his precautions. He would take no chances, and would keep up a watch day and night.
When, on the night before, the time had come for Ralph's watch to end, his sister had awakened him, and when the captain, in his turn, was aroused, he had not known that it was not the boy who had kept watch during his sleep.
In the course of the morning Mrs. Cliff and Edna, having been filled with an intense desire to see the wonderful subterranean lake, had been helped over the rocky barrier, and had stood at the edge of the water, looking over to where it was lighted by the great chasm in the side of the rocks, and endeavoring to peer into the solemn, cavernous distance into which it extended on the right. Edna said nothing, but stood gazing at the wonderful scene—the dark, mysterious waters before her, the arched cavern above her, and the picture of the bright sky and the tops of the distant mountains, framed by the sides of the great opening
