The travelers stayed at Fort Mandan till the beginning of April; then the ice being melted on the river they set out again.
Game now became more than ever plentiful, and they had several encounters with huge grizzly bears. The Indians had told the explorers terrible stories about these bears. They themselves had such great respect for them that they never went out to hunt them without putting on their war paint, and making as great preparations as if they were going to fight some enemy tribe.
The white men too soon came to have a great respect for them. "I find," wrote Lewis, in his journal, "that the curiosity of our party is pretty well satisfied with respect to this animal. He has staggered the resolution of several of them."
Later on he added, "I must confess that I do not like the gentlemen, and had rather fight two Indians than one bear."
One day Lewis was on shore, and seeing a herd of buffalo shot one for supper. After it fell he stood looking at it, and forgot to load his rifle again. While standing thus he suddenly saw a large bear creeping towards him. Instantly he lifted his rifle, but remembered in a flash that it was not loaded. He had no time to load, so he thought the best thing he could do was to walk away as fast as he could.
It was in an open plain with not a bush or tree near; and as Lewis retreated the bear ran open-mouthed at full speed after him. Lewis took to his heels and fled. But the bear ran so fast that Lewis soon saw that it would be impossible to escape, for the bear was gaining fast upon him. Then suddenly it flashed across his mind that if he jumped into the river he might escape. So turning short he leaped into the water. Then facing about he pointed his halberd at the bear. Seeing this the bear suddenly stopped on the bank not twenty feet away. Then as if he were frightened he turned tail and ran away as fast as he had come.
Lewis was glad enough to escape so easily, and he made up his mind that never again would he allow his rifle to be unloaded even for a moment.
Other dangers, too, beset the travelers. One day Lewis and his companions were following the boats along the bluffs which rose high above the water's edge. The ground was so slippery that they could only with difficulty keep their feet. Once Lewis slipped and only saved himself by means of the pike which he carried from being hurled into the river a hundred feet below. He had just reached a spot where he could stand fairly safely when he heard a voice behind him cry out: "Good God! Captain, what shall I do?"
He turned instantly and saw that one of his men who had lost his foothold had slipped down to the very edge of the precipice and was now hanging half over it. One leg and arm were over, and with the other he clung frantically to the edge of the cliff.
Lewis saw at once that the man was in great danger of falling and being dashed to pieces below. But he hid his fear.
