The captain took the pistol from her hands and examined it. "Five chambers," he said, "all charged. Be very careful of it,"—handing it back to her. "I will put your brother and Mrs. Cliff in your charge. At the slightest hint of danger, you must keep together in the middle room. I will stand between you and the rascals as long as I can, but if I am killed, you must do what you think best."

"I will," said she, and she put the pistol back in her pocket.

The captain was very much encouraged by the brave talk of this young woman, and it really seemed as if he now had some one to stand by him, some one with whom he could even consult.

"I have carefully examined this cavern," said the captain, after a moment's pause, "and there are only two ways by which those men could possibly get in. You need not be afraid that any one can scramble down the walls of that farthest apartment. That could not be done, though they might be able to fire upon any one in it. But in the middle room you will be perfectly secure from gunshots. I shall keep Maka on guard a little back from the entrance to the passage. He will lie on the ground, and can hear footsteps long before they reach us. It is barely possible that some of them might enter by the great cleft in the cave on the other side of the lake, but in that case they would have to swim across, and I shall station that new African on the ledge of which you have heard, and if he sees any of them 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.
