He was separated from Ako and Du Gay, who were taken to other villages. By the time he reached father Aquepaguetin's house he was so exhausted, and his legs, cut by ice in the streams, were so swollen that he fell down on a bear robe. The village was on an island in a sheet of water afterwards called Lake Buade. Hennepin was kindly received by his new family, who fed him as well as they were able, for the Sioux had little food when they were not hunting. Seeing him so feeble, they gave him an Indian sweating bath, which he found good for his health. They made a lodge of skins so tight that it would hold heat, and put into it stones baked to a white heat. On these they poured water and shut Hennepin in the steam until he sweated freely. The Sioux had two kinds of lodges--one somewhat resembling those of the Illinois, the other a cone of poles with skins stretched around, called a tepee. Father Hennepin did little missionary work among these Indians. He suffered much from hunger, being a man who loved good cheer. But the tribes went on a buffalo hunt in July and killed plenty of meat. All that northern world was then clothed in vivid verdure. Honeysuckles and wild grapevines made the woods fragrant. The gentian, which jealously closes its blue-fringed cup from the human eye, grew close to the lakes. Captive though the Frenchmen were, they could not help enjoying the evening camp-fire with its weird flickerings against the dark of savage forests, the heat-lightning which heralded or followed storms, the waters, clear, as if filtered through icebergs, dashing in foam over mossy rocks. They met during the buffalo hunt, and it was about this time that some "spirits," or white men, were heard of, coming from Lake Superior. These proved to be the great ranger Greysolon du Lhut and four other Frenchmen. This man, cousin to Tonty, passed nearly his whole life in the woods, going from Indian town to Indian town, or planting outposts of his own in the wilderness. Occasionally he went to France, and the king's magnificence at Versailles was endured by him until he could gain some desired point from the colonial minister and hurry back. The government relied on him to keep lawless coureurs de bois within bounds, and he traded with nearly all the western tribes. When Greysolon du Lhut appeared, the Sioux treated their prisoners with deference; and from that time Hennepin, Du Gay, and Ako went where they pleased.
