In his struggles to succeed Will had taken little notice of the coldness of the waters, but when he went back to the lodge he had a severe chill, followed by a high fever. Then old Inmutanka proved himself the doctor that Will called him by using a remedy that either killed or cured.

Inmutanka gave the lad a sweat bath. He made a heap of stones and built a big fire upon them, feeding it until their heat was very great. Then he scraped away the fuel and put up a framework made of poles, covered with layers of skins. These layers were six or seven feet above the stones. Will was placed in a skin hammock under the layers and suspended about two feet above the hot stones. Water was then poured on these, until a dense steam arose. When Inmutanka thought that Will had stood it as long as he could, he withdrew him from the hot steam bath, although medicine men sometimes left their patients in too long, allowing them to be scalded to death.

In Will's case it was cure, not kill. The fever quickly disappeared from his system and though it left him very weak he recovered so rapidly that in a few days he was as strong as ever, in fact, stronger, because all the impurities had been steamed out of his system, and the new blood generated was better than the old. He learned, too, from Inmutanka that he had won respect in the village by his courage and tenacity, and that many were in favor of lightening his labors, although the Fox was as stern as ever.

Will was still compelled to realize that he was a slave; that he, a white lad, the heir of untold centuries of civilization and culture, was the slave of a people who, despite all their courage and other virtues, were savages. They stood where, in many respects, his ancestors had stood ten or twenty thousand years ago. Again and again, the thought was so bitter that he felt like making a run for freedom and ending it all on the Indian spear. But the thought would change, and with it came the hope that some day or other the moment of escape would appear, and there was a lurking feeling, too, that his present life was not wholly unpleasant, or, at least, there were compensations.

An increased strength came with the rapid recovery from his illness. Beyond any question he had grown in both height and breadth since he had been in the mountains, and his muscles were as hard as iron. Not one of the Indian youths could exert as much direct strength as he, or endure as much.

His patience, which was now largely the result of calculation and will, began to have its visible effect upon the people. There is nothing that an Indian admires more than stoicism. The fortitude that can endure pain without a groan is to him the highest of attributes. Will had never complained, no matter how great his hardships or labors, and gradually they began to look upon him as one of their own. His face was tanned heavily by continuous exposure to all kinds of weather, his original garments were worn out, and he was now clad wholly in deerskins. A casual observer would have passed him at any time as a tall Indian youth.

One day as a mark of favor he was put back as a guard upon the herd of ponies, now considerably increased in numbers, probably by raids upon other tribes, and full of life, as they had done little all the autumn but crop the rich grass of the valley. Will found himself busy keeping them within bounds, but his old, happy touch soon returned, and the Indians, to their renewed amazement, soon saw the animals obeying him instinctively.

"It is magic," said old Xingudan.

"Then it is good magic," said Inmutanka, "and Wayaka is a good lad. He does not know it yet, but he is beginning to like our life. Think of that, O, Xingudan."

"You were ever of soft heart, O, Inmutanka," said Xingudan, as he turned away.
