Some drifting clouds now passed and the moonlight shone with a sudden burst of splendor. Henry was close to the stakes and suddenly he shuddered in every vein. They were about as high as a man's head, firmly fastened in the ground, and all of them were blackened and charred somewhat by fire, although their strength was not impaired. At the base of every one lay hideous relics. Henry shivered again. He knew. Here Indians brought their captives and burned them to death, partly for the sake of their own vengeance and partly to propitiate the mighty spirits that had their abode in the depths of the great lakes. He was sure that his comrades and he had landed upon a sacrificial island, and he resolved that they should depart at the very first light in the morning.
This island which had seemed so fine and beautiful to him suddenly became ghastly and repellent, but his second thought told him that they had nothing to fear at present. It was not inhabited. The warriors merely came here for the burnings, and then it was quite likely that they departed at once.
Henry examined further. On the bushes beyond the stakes he found amulets and charms of bone or wood, evidently hung there to ward off evil spirits, and among these bushes he saw more bones of victims. Then he noticed two paths leading away from the place, each to a small inlet, where the boats landed. Calculating by the moon and stars he could now obtain a general idea of the direction in which they had come and he was sure that the nearest part of the mainland lay to the west. He saw a dark line there, and he could not tell whether it was the shore or a low bank of mist.
Then he made a diligent exploration of all this part of the island, assuring himself further that it had never been occupied permanently. He saw at one place the ruins of a temporary brush shelter, used probably during a period of storm like that of the night before, and on the beach he found the shattered remains of a large canoe. Henry looked down at the broken canoe thoughtfully. It may have been wrecked while on its way with a victim for the stake, and if the warriors had perished it might have been due to the wrath of the Great Spirit.
He walked slowly back over the ridge through the forest and down to the boat. Tom saw him coming but said nothing until he stepped into the boat beside him.
