The writer does not speak at random or by hearsay of Indian life. He saw and studied something of it, more than half a century ago, before civilization had wrought the changes now seen. Indians are profound believers in the immortality of the soul. Some suspend their dead in the leafy treetops, that they may the more easily ascend to "the happy hunting-grounds." The custom of many is to kill the favorite horse and bury it with all accoutrements and implements of war, as well as their finest garments, believing the spirit will need them and receive greater honor. The leading thought of the Indian seems to be that all material things have a spirit that is immortal. The Indian burying-grounds are sacred spots and seldom if ever are desecrated in savage life, even by their worst enemies. Some of the beautiful little islands in the rivers of the Far West have thus been used, as the many ruins testify. It has long been noted that Indians in war will risk their own lives to carry off and bury their dead and prevent mutilation of bodies. _Is the Story of the Flathead Chiefs of 1831-32 Authentic?_ So strange and so without precedent in savage life was the mission of the Indians to St. Louis, that many have doubted the truthfulness of the report, and have called it "visionary." Fortunately the reader need not be in doubt in regard to the entire truthfulness of the event as reported. The Christian people of that time believed and acted upon it in a way to convince every honest mind of their earnestness. It may be said the incident made a profound impression in the religious world, and the history we are to recite of the after-results mark it as one of the providential events guiding the nation by unseen hands to its destiny. Had such a notable event occurred in modern days, it would have entered at once into current literature. That it did not at the time is no disparagement of its truthfulness. There is one strong chain of evidence regarding the mission of the Nez Perces chiefs, not easily broken; that is, the written evidence of George Catlin. Aboard the steamer Yellowstone, upon which General Clark sent his savage friends, there happened to be a celebrated artist, George Catlin, then on one of his visits to the West to paint Indian pictures and study Indian life. These Nez Perces chiefs at once attracted him, and they became intimate friends--during the long journey he made pictures of them. Indians are not great talkers, and he did not learn much from them as to the object of their long journey. From others afterward he heard of their strange mission to St. Louis, and believing he had secured two historic pictures, he first wrote General Clark, and afterward met him, and was assured by him that such was the mission of the four Flathead chiefs. Catlin, in his Smithsonian report for eight years, in 1885, says:
