“So we have,” replied Chester; “but the question is, what?”
Hal was silent for several minutes, thinking. Finally he said:
“Well, I guess the best thing to do is to wait and see what happens. Perhaps they may leave before broad daylight and not discover this cave. In that case we shall be safe enough. Now you stay here and guard this end, and don’t move unless I call. I’ll do the same at the other end.”
“All right,” said Chester. “We’ll keep our posts till daylight, whether they go away or not. Then, if we have not been discovered, we can at least see what we are doing.”
Hal moved slowly along the passageway once more, being very careful not to make any noise. He crawled on hands and knees, his head thrust out before him.
Suddenly, as he moved slowly along, his head came in contact with another moving object with an audible crack.
He had bumped into a second crawling figure.
