Some years before this a United States Captain, Robert Grey, had discovered a great river in the west coast of America and called it the Columbia, after the name of his ship. And now what Lewis and Clark had set out to do was to reach that river from the east.
It is impossible to tell here of all their thrilling adventures, for they would fill a whole book. I can only give you the merest outline. But some day you will no doubt read the whole story as Lewis and Clark tell it themselves.
The expedition started from the mouth of the Missouri, and at first the explorers passed by the scattered farms and little villages where white men lived. But these were the farthest outposts of civilisation; soon they were left behind, and the little band of white men were in a land inhabited only by Redskins. The current was so swift and the wind so often in the wrong direction that sails were almost useless, and the boats were rowed, punted and towed upstream with a great deal of hard labour. Some of the travelers went in the boats, others rode or walked along the bank. These last did the hunting and kept the expedition supplied with meat.
One of the leaders always went with those on shore. For it was often difficult for the two parties to keep together. Sometimes the river wound about, and those on land could take a short cut, while at other times those on land had to make a wide circuit to avoid marshes or steep precipices. The river was full of fish, and the land swarmed with game. Antelopes, deer, black bear, turkeys, geese, ducks, in fact all sorts of birds and beasts were abundant. There were also great quantities of delicious wild grapes as well as plums, currants and other fruits; so the travelers had no lack of food.
They met many tribes of Indians and they nearly all seemed friendly, for both Lewis and Clark knew well how to treat Indians. When they came into their land they called the chiefs together to a council, and made them a speech telling them that the land was no longer Spanish but American. The Indians would pretend to be pleased at the change, but really they understood nothing about it. But they liked the medals and other trinkets which the white men gave them. And most of them were very anxious to have some of the "Great Father's Milk" by which they meant whiskey. But one tribe refused it.
"We marvel," they said, "that our brothers should give us drink which will make us fools. No man can be our friend who would lead us into such folly."
Until the end of October the expedition kept on, always following the course of the Missouri, north-west. But the weather now became very cold; ice began to form on the river, and the explorers determined to camp for the winter. Not far from what is now the town of Bismarck, North Dakota, they built themselves a little village of log huts and called it Fort Mandan, for the country belonged to the Mandan Indians.
Here they met both French and British fur traders, who in spite of the bitter weather came from Assiniboia, about a hundred and fifty miles north, to trade for furs with the Indians.
The weather was bitterly cold, but the men were fairly comfortable in their log huts, and they had plenty to do. They went upon hunting expeditions to get food, they built boats, and they set up a forge. This last greatly interested the Indians who brought their axes and kettles to be mended, and in return gave the white men grain. Soon the smith was the busiest man in the whole company, the bellows particularly interesting the Redmen.
Indeed everything about the white strangers was so interesting to the Indians that they were nearly always in their huts. On Christmas Day the travelers only got rid of their inquisitive visitors by telling them that it was a great medicine day with the white people, when no strangers were allowed near them, and they must keep away.
