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. [Illustration: Captain Meriwether Lewis.] 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. The clear waters of the Judith River and its woods beautiful with multitudinous mountain roses, the fragrant honeysuckle, and the tiny red willows delighted their eyes; but the sight of a hundred and twenty-six lately abandoned lodge-fires caused some uneasiness, as indicating a late camping-place of a war-party of vicious northern Minnetarees or Blackfeet.
