“I’m afraid we will.”

Despite their caution in proceeding, at one point, Grant, breaking through the brushwood bridge with a cracking sound, plunged one leg to the thigh between the two lengthwise supports and drew it forth soaking wet.

“This yere trail,” said the Texan, “is sure some unreliable and treacherous.”

Those who reached the island first waited for the others to come up. They stood there whispering and listening, but hearing no sounds to assure them that the one they sought was near.

“As he’s deranged,” said Piper, “we want to take care not to frighten him more than possible, for it’s likely he’ll be scared and run when he sees us.”

“He can’t run fur,” declared Crane, “without plungin’ head over heels right into the swamp.”

“And that’s what we don’t want him to do; it might be his finish. We must prevent him from running away when we find him.”

“When we find him,” muttered Nelson. “But something tells me we won’t find him here.”

Slowly they pushed forward toward the center of the island. In a few moments they came to a small opening and paused again, before them the old camp huddling in the shadows of a thick grove which rose close beside it. The place was dolefully silent and forbidding at that hour. A breath of wind, sweeping across the island, set up a sudden rustling, which was accompanied by a sound that put their nerves on edge.

That sound was like a low, harsh moan or groan, and it seemed to come from the sagging, deserted camp before them. Some shrank back shivering, while others appeared eager to rush forward.
