"But they may have candles or matches," said Edna. "We must try to keep them out of the big cave."

Ralph did not stop to answer, but ran as fast as his legs would carry him to the plateau. The rest of the party followed, Edna first, then the negroes, and after them Mrs. Cliff, who could not imagine why Edna should be in such a hurry. The sailors, having secured their boat, came straggling after the rest.

When Edna reached the entrance to the caves, she was met by her brother, so much out of breath that he could hardly speak.

"You needn't go to your room to get your things," he exclaimed. "I have gathered them all up, your bag, too, and I have tumbled them over the wall in the entrance back here. You must get over as quick as you can. That will be your room now, and I will tell the sailors, if they go poking around, that you are in there getting ready to leave, and then, of course, they can't pass along the passage."

"That is a fine idea," said Edna, as she followed him. "You are getting very sharp-witted, Ralph."

"Now, then," said he, as he helped her over the wall, "take just as long as you can to get your things ready."

"It can't take me very long," said Edna. "I have no clothes to change, and only a few things to put in my bag. I don't believe you have got them all, anyway."

"But you must make it take a long time," said he. "You must not get through until every sailor has gone. You and I must be the last ones to leave the caves."

"All right," said Edna, as she disappeared behind the wall.

When Mrs. Cliff arrived, she was met by Ralph, who explained the state of affairs, and although that lady was a good deal annoyed at the scattered condition in which she found her effects, she accepted the situation.
