"He heard a voice behind him cry out, 'Good God, Captain, what shall I do?' He turned instantly and found it was Windsor, who had lost his foothold about the middle of the narrow pass and had slipped down to the very verge of the precipice, where he lay on his belly, with his right arm and leg over the precipice, while with the other leg and arm he was with difficulty holding on to keep himself from being dashed to pieces below. His dreadful situation was instantly perceived by Captain Lewis, who, stifling his alarm, calmly told him that he was in no danger, that he should take his knife out of his belt with the right hand and dig a hole in the side of the bluff to receive his foot. With great presence of mind he did this, and then raised himself on his knees. Captain Lewis then told him to take off his moccasins and come forward on his hands and knees, holding the knife in one hand and his rifle in the other. He immediately crawled in this way till he came to a secure spot." One of Lieutenant Clark's party, on the south fork, at the same time, ran great danger from a grizzly bear which attacked near camp a man whose gun, being wet, would not go off. The man took to a tree, so closely followed by the animal that he struck the hunter's foot as he was climbing. The bear showed his intention of waiting until the man should be forced to descend, but fortunately alarmed by the cries and signal-shots of a searching-party decamped. While Lewis and Clark concurred in believing the south fork to be the true Missouri, the rest of the party were unanimous in thinking the north the right course. Finally caching their heaviest boat and all the supplies which could well be spared, the entire party followed the south fork.
