“When the Indians engage in killing buffalo, the hunters mount on horseback and, armed with bows and arrows, encircle the herd and gradually drive it into a plain or open place fit for the movement of horse; they then ride in among them, and singling out a buffalo, a female being preferred, go as close as possible and wound her with arrows till they think they have given the mortal stroke; when they pursue another till the quiver is exhausted. If, which rarely happens, the wounded buffalo attacks the hunter, he evades the blow by the agility of his horse, which is trained for the combat with great dexterity.”

The winter proved to be of unusual severity, and several times the temperature fell to forty degrees below zero, and proof spirits froze into hard ice. The fortitude with which the hardy savages withstood such extreme cold, half naked as they often were, impressed our explorers.

Spring opened early, and on April 7, 1805, Fort Mandan was abandoned, one party of ten with the barge going down the river with despatches and specimens. Lewis and Clark with their party of thirty started up the Missouri in six canoes and two large open boats, which had been constructed by them. They had three interpreters—Drewyer, Chaboneau, and his wife. Drewyer was a Canadian half-breed who had always lived in the woods, and while he had inherited from his mother the intuitive sagacity of the Indian in following the faintest trail, he had also acquired to a wonderful degree that knowledge of the shifts and expedients of camp life which is the resource and pride of the frontier huntsman. Chaboneau’s life had been largely spent among the Blackfeet, by whom his wife, a Snake Indian, had been taken in war and enslaved when a young girl.

At the mouth of the Little Missouri the three French hunters, who had ventured to follow the party, stopped for trapping, as they found beaver very plentiful. Chaboneau Creek, the farthest point on the Missouri yet visited by white men, was passed, and on April 26th they arrived at the mouth of the Yellowstone. Lewis was here particularly pleased with the wide plains, interspersed with forests of various trees, and expressed his opinion that the situation was most suitable for a trading establishment.

Spring had now fairly opened, the trees were in leaf, a flower was seen, and despite the scanty verdure of the new grass, game was very abundant. In many places, however, the barren banks and sand-bars were covered with a white incrustation of alkali salts, looking like frost or newly fallen snow, which were present in such quantities that all the small tributaries of the Missouri proved to be bitter and unhealthy water. Signs of human life became rarer, but now and then they passed an old Indian camp, and near one saw the burial place of an Indian woman. The body, carefully wrapped in dressed buffalo robes, rested on a high scaffold, with two sleds and harness over it. Nearby lay the remains of a dog sacrificed to the shades of his dead mistress. In a bag were articles fitting for women—moccasins, red and blue paint, beavers’ nails, scrapers for dressing hides, dried roots, a little Mandan tobacco, and several plaits of sweet-smelling grass.

The oar was plied unceasingly save when a favoring wind filled their sails and facilitated their progress. In early May they drew up their canoes for the night at the mouth of a bold, beautiful stream, and in the abundant timber found feeding on the young willows so many clumsy porcupines that they called it Porcupine River. Game was present in vast quantities; the elk were tame, and the male buffalo would scarcely quit grazing at the approach of man. As Lewis remarks: “It has become an amusement to supply the party with provisions.”

On May 8th they dined at the mouth of a river flowing from a level, well-watered, and beautiful country. As the water had a peculiar whiteness they were induced to call it Milk River. The Missouri now turned to the southwest and south, the country became more open, and timber, of pine mostly, small and scanty.

Although the buffalo were so tame and harmless that the men drove them out of their way with sticks, yet the grizzly bear never failed to be a dangerous and vicious visitor. One day six good hunters attacked a grizzly, and four firing at forty paces, each lodged a ball in the body, two going through the lungs. The animal ran at them furiously, when the other hunters fired two balls into him, breaking a shoulder. The bear yet pursued them, driving two into a canoe and the others into thickets, from which they fired as fast as they could reload. Turning on them, he drove two so closely that they dropped their guns and sprang from a precipice twenty feet high into the river followed by the bear, who finally succumbed to a shot through the head after eight balls had passed completely through his body. Another bear, shot through the heart, ran a quarter of a mile with undiminished speed before he fell dead.

On the 20th, twenty-two hundred and seventy miles from St. Louis, they came to the greenish-yellow waters of the Musselshell, and a short distance beyond Captain Lewis caught his first glimpse of the Rocky Mountains, the object of his hope and ambition. Beyond the Musselshell their experiences were less pleasant: the country became more barren, game and timber scarce, mosquitoes annoying; the high dry winds, full of sand, made their eyes sore; the sun of midday burned, while almost every night ice or frost chilled them.
