In a moment the whites were made prisoners. The scowling looks and threatening gestures of their captors boded them no good. Hennepin proffered the peace-pipe. It was snatched from his hand. When he began muttering prayers aloud, the Indians angrily signed to him to be silent, thinking he was preparing some charm to overpower them with, but they let him chant the same prayers, he says, thinking there could be no sorcery or medicine in song. Presently the Sioux began their homeward journey, thus making it clear to the Frenchmen that their future discoveries must be made as captives. In nineteen days the party landed near the site of St. Paul.[4] From here the trail was struck leading to the Sioux villages, which were reached after five days of hard marching and harder usage at the hands of the Sioux warriors. Here the prisoners were separated, Hennepin going to an aged chief who adopted him as his own son. So they passed the winter among the Sioux. In the following summer, when the Sioux went on their annual buffalo hunt, they took the three Frenchmen along with them. This was the prisoners' opportunity for regaining their liberty, and they hastened to make use of it. La Salle had promised to send word of himself to them at the mouth of the Wisconsin, and they knew he would not fail them. Telling the Sioux their friends were coming, loaded with gifts, the greedy Sioux were easily induced to let Hennepin and one other go down the river to meet them alone and unguarded. One Frenchman remained behind with the Sioux as a hostage for the others. The two whites began their descent of the river, carrying their canoe round the Falls of St. Anthony,[5] to which Father Hennepin gave this name, till, after many adventures, Lake Pepin[6] was reached. [Illustration: SIOUX CHIEF.] To their consternation, the travellers were overtaken at this point by a party of Sioux who had followed their prisoners so closely, as hardly to lose sight of them, and now pushed on ahead to the Wisconsin. Finding neither traders[7] nor goods there, as they had been led to expect, the Sioux paddled back again in bad humor to the place where the whites had remained. After being soundly rated for the cheat they had practised, the unlucky whites were forced to turn about and go back again as they came. After some longer stay among the Sioux, the captives were found by some French traders who had made their way from Lake Superior, through the Sioux country, to the Mississippi. Hearing of the three white men, while on the way, these traders had kept on from village to village, till they reached the one in which Hennepin and his companions were detained, and ransomed them out of the hands of the savages.
