The boat was drawn entirely out of the water and covered as much as possible with leaves and undergrowth; for it was a loss that under any circumstances they could not sustain. The feat of marking the place so that they could readily return to it from any direction was more difficult; but Howard finally hit upon quite an ingenious scheme. They waited until the sun had approached near enough to the horizon that they could tell precisely the point where it would appear, and then turning their backs against it they walked forward until they reached the hills where Elwood had disappeared. Here they noticed the character and formation of the rocks so particularly that they could recognize them the moment they saw them. Thus the hills were such a conspicuous landmark as to be seen from a great distance; and, as they did not intend to go out of their sight, all they had to do was to hunt till they found this spot, and then walk due east.

All this was agreed upon, and they were among the hills just as the sun was coming up the horizon. Here, after whistling and shouting for sometime without receiving any response, they concluded to search for the point where the boys separated. This was quite distant, and over an hour was required to find the place, and when it was discovered Howard could not be positive that he was right.

But as time was of the greatest importance, they pressed on, the dog snuffing the ground as though he had scented the footprints, but he failed to follow them with certainty. Several hundred yards brought them to an opening in the hills just broad enough to admit the body of a man. It was not a tunnel-like opening, but a rent, as if the hills had been pulled a few feet asunder by the power of an earthquake.

The two paused in doubt before this.

"He went in there," said Tim. "He couldn't help it, no matter how great his hurry."

"I am half disposed to believe you; at any rate let us follow it some ways."

Terror was running over the ground, as though he had made a discovery, and he finally whisked forward out of sight.

"That looks as if he were upon his trail."

"Yis, or somebody ilse's; maybe some of the rid gintlemen has took his marnin' walk in this direction."

They followed the path with caution, and were surprised the further they advanced. It wound around and among the rocks, which came so close together as to forbid the passage of a man, and the sides never withdrawing more than a dozen feet.
