Then they set out again on their journey, which presently became most difficult. For nearly a month they painfully made their way through dense forests, over steep mountains, and across raging torrents, whose icy water chilled both man and beast. Sometimes storms of sleet and snow beat pitilessly down upon them, and again they were almost overcome by oppressive heat.

Game was so scarce that the men often went hungry, and were even driven to kill some of their horses for food.

But brighter days were bound to come, and at last they reached a river which flowed toward the west. They called it Lewis, and it proved to be a branch of the Columbia, which led to the sea. With fresh courage they built five canoes, in which the ragged, travel-worn but now triumphant men made their way down-stream. The Indians whom they met were for the most part friendly, welcoming them and providing them with food, though a few tribes were troublesome.

Before the cold of the second winter had set in they had reached the forests on the Pacific coast, and here they stayed until spring, enduring much hunger and cold, but learning many things about the habits of the Indians.

The Lewis and Clark Expedition Working Its Way Westward.

The next March, as soon as travel was safe, they gladly turned their faces homeward, and after a fatiguing journey of about three months, reached the Great Plains.

Then the party separated for a time into two companies, Clark following the course of the Yellowstone River, and Lewis the Missouri, planning to meet where the two rivers united.

This they succeeded in doing, though both parties were troubled somewhat by Indians. The Crow Indians stole horses from Clark’s party, and eight Blackfoot warriors attacked Lewis and three of his men. But Lewis got the better of them and captured four of their horses.

The explorers suffered no further injury, and in September, 1806, about two years and four months after starting out, they were back in St. Louis, with their precious maps and notes. They had successfully carried out a magnificent undertaking, and you may be sure they received a joyful welcome from their friends. I wonder if any of you can tell which of our world’s fairs commemorated the leaders of this expedition.
