"Dec. 12, 1804.--The thermometer at sunrise was thirty-eight degrees below zero; on the 16th, twenty-two below; on the 17th, forty-five below. On the 19th, it moderated a little. Notwithstanding the cold, we observed the Indians at the village engaged, out in the open air, at a game which resembles billiards. The platform, which answered for a table, was formed with timber, smoothed and joined so as to be as level as the floor of one of our houses. Instead of balls, they had circular disks made of clay-stone, and flat like checkers." THE ARGALI. "Dec. 22.--A number of squaws brought corn to trade for small articles with the men. Among other things, we procured two horns of the animal called by the hunters the Rocky-Mountain sheep, and by naturalists the argali. The animal is about the size of a small elk or large deer; the horns winding like those of a ram, which they resemble also in texture, though larger and thicker. "Dec. 23.--The weather was fine and warm. We were visited by crowds of Indians of all description, who came either to trade, or from mere curiosity. Among the rest, Kagohami, the Little Raven, brought his wife and son, loaded with corn; and she entertained us with a favorite Mandan dish,--a mixture of pumpkins, beans, corn, and choke-cherries, all boiled together in a kettle, and forming a composition by no means unpalatable. "Dec. 25.--Christmas Day. We were awakened before day by a discharge of fire-arms from the party. We had told the Indians not to visit us, as it was one of our great Medicine-days; so that the men remained at home, and amused themselves in various ways, particularly with dancing, in which they take great pleasure. The American flag was hoisted for the first time in the fort; the best provisions we had were brought out; and this, with a little brandy, enabled them to pass the day in great festivity." THE BLACKSMITH. "Dec. 27.--We were fortunate enough to have among our men a good blacksmith, whom we set to work to make a variety of articles. His operations seemed to surprise the Indians who came to see us; but nothing could equal their astonishment at the bellows, which they considered a _very great Medicine_." THE DYING CHIEF. "Kagohami came to see us early. His village was afflicted by the death of one of their aged chiefs, who, from his account, must have been more than a hundred years old. Just as he was dying, he requested his grand-children to dress him in his best robe, and carry him up to a hill, and seat him on a stone, with his face down the river, towards their old village, that he might go straight to his brother, who had passed before him to the ancient village underground." THE MEDICINE-STONE.
