They paddled sixty leagues down the river in the heats of July, and killed no large game but a single deer, the meat of which soon spoiled. Their main resource was the turtles, whose shyness and watchfulness caused them frequent disappointments, and many involuntary fasts. They once captured one of more than common size; and, as they were endeavoring to cut off his head, he was near avenging himself by snapping off Hennepin's finger. There was a herd of buffalo in sight on the neighboring prairie; and Du Gay went with his gun in pursuit of them, leaving the turtle in Hennepin's custody. Scarcely was he gone when the friar, raising his eyes, saw that their canoe, which they had left at the edge of the water, had floated out into the current. Hastily turning the turtle on his back, he covered him with his habit of St. Francis, on which, for greater security, he laid a number of stones, and then, being a good swimmer, struck out in pursuit of the canoe, which he at length overtook. Finding that it would overset if he tried to climb into it, he pushed it before him to the shore, and then paddled towards the place, at some distance above, where he had left the turtle. He had no sooner reached it than he heard a strange sound, and beheld a long file of buffalo,--bulls, cows, and calves,--entering the water not far off, to cross to the western bank. Having no gun, as became his apostolic vocation, he shouted to Du Gay, who presently appeared, running in all haste; and they both paddled in pursuit of the game. Du Gay aimed at a young cow, and shot her in the head. She fell in shallow water near an island, where some of the herd had landed; and, being unable to drag her out, they waded into the water and butchered her where she lay. It was forty-eight hours since they had tasted food. Hennepin made a fire, while Du Gay cut up the meat. They feasted so bountifully that they both fell ill, and were forced to remain two days on the island, taking doses of orvietan, before they were able to resume their journey.
