“Throughout the whole, game was very abundant. They procured deer in the low grounds; beaver and otter were seen in Gallatin River, and elk, wolves, eagles, hawks, crows, and geese at different parts of the route. The plain was intersected by several great roads leading to a gap in the mountains, about twenty miles distant, in a direction E.N.E.; but the Indian woman, who was acquainted with the country, recommended a gap more to the southward. This course Captain Clark determined to pursue.” Let us pause here to pay a little tribute to the memory of “the Indian woman,” Sacajawea. She showed that she was very observant, had a good memory, and was plucky and determined when in trouble. She was the guide of the exploring party when she was in a region of country, as here, with which she was familiar. She remembered localities which she had not seen since her childhood. When their pirogue was upset by the carelessness of her husband, it was she who saved the goods and helped to right the boat. And, with her helpless infant clinging to her, she rode with the men, guiding them with unerring skill through the mountain fastnesses and lonely passes which the white men saw for the first time when their salient features were pointed out to them by the intelligent and faithful Sacajawea. The Indian woman has long since departed to the Happy Hunting-Grounds of her fathers; only her name and story remain to us who follow the footsteps of the brave pioneers of the western continent. But posterity should not forget the services which were rendered to the white race by Sacajawea. On the fifteenth of July the party arrived at the ridge that divides the Missouri and the Yellowstone, nine miles from which they reached the river itself, about a mile and a half from the point where it issues from the Rocky Mountains. Their journey down the valley of the Yellowstone was devoid of special interest, but was accompanied with some hardships. For example, the feet of the horses had become so sore with long travel over a stony trail that it was necessary to shoe them with raw buffalo hide. Rain fell frequently and copiously; and often, sheltered at night only by buffalo hides, they rose in the morning drenched to the skin. The party could not follow the course of the river very closely, but were compelled often to cross hills that came down to the bank, making the trail impassable for horses. Here is the story of July 18 and 19:--
