When Osceola was first captured he was imprisoned in Fort Marion, but was afterward removed to Sullivan's Island, where his wife and child accompanied him. He was a sad prisoner--never known to laugh during his confinement, but often heard to sigh. During his last illness he had the best medical attention from Charleston, whose skill he refused, believing they intended poisoning him. To one of his wives he was much attached, and his spirit passed away while leaning on her bosom. He died in 1838, from an inflammation of the throat. The eagle plumes droop o'er his piercing eyes, The fire of youth was there! Osceola had always lived among the Seminoles, and regarded their lot as his. The name of his wife was Chécho-ter, or Morning Dew. She was a Creek, and their family consisted of four children. The following lines were composed after his death by one of his friends in Charleston: The rich blue sky is o'er, Around are tall green trees, And the jasmine's breath from the everglades Is borne on the wand'ring breeze. On the mingled grass and flowers Is a fierce and threat'ning form, That looks like an eagle when pluming his wing To brave the gath'ring storm. We recently conversed with a missionary from the Creek Nation, who had been preaching among the Indians in that locality, who says Osceola has two sisters living there, both exemplary Christians, upon whom the serpent's trail had evidently rested very lightly. CHAPTER VII. As we approach the upper shores of the St. John's River, extensive swamp-lands, overgrown with various kinds of timber, are seen, where very bony-looking stock eke out a spare subsistence during a portion of the year, but commence recruiting as soon as the grass begins to grow, in February. Habitations are not frequent, the only variations being mounds, or bluffs, as they are usually termed. Many of these voiceless monuments of the mute past, around which cluster records of deep import, are found scattered throughout various portions of Florida, as in many other localities, furnishing food for the thoughtful, and conjecture for the inquiring mind. All efforts heretofore made to enlighten the world, or explain these curious structures, are founded upon the diversity of opinion and research of the different writers. Their appearance sheds sufficient light on the subject for us to know they are the cemeteries of an early, though partial, civilization--probably a relic of the Mexican race--from which we may derive illustrations of the habits, manners, and ideas of a people, "on whose graves the firmly-rooted oak has so long kept its dominion that it seems to the Indian supplanters to have been the first occupant of the soil."
