allowed him to return through Texas to the United States.
Both these expeditions were subordinate to the larger exploration of Lewis and Clark, which President Jefferson himself organized, and in which he took deep interest. After passing the winter at the Mandan village, as has been already told, Lewis with thirty-two men set out April 7 in boats and canoes for the headwaters of the Missouri. The journey proved to be full of labor, but remarkably free from danger; the worst perils encountered were from rattlesnakes and bears. The murderous Sioux were not seen; and when, August 11, Lewis reached the end of river navigation, and found himself at the base of the mountains that divided the waters of the Missouri from those of the Columbia, his greatest anxiety was to meet the Indians who occupied the line of passage, His troubles rose from the poverty, rather than from the hostility, of these tribes. They supplied him with horses and with such provisions as they had, and he made his way peacefully down the western slope until he could again take canoes. November 7 the explorers reached the mouth of the Columbia River, and saw at last the ocean which bounded American ambition. There they were forced to pass the winter in extreme discomfort, among thievish and flea-bitten Indians, until March 26, 1807, they could retrace their steps.
Creditable as these expeditions were to American energy and enterprise, they added little to the stock
