The commencement of this swamp is thirty or forty miles south of the Caloosahatchee, extending within twenty miles of Lake Okachobee to the Gulf. On approaching the lake it terminates in thick mangrove bushes, uninhabitable for Indians. Between the Caloosahatchee the country is wet pine barren, with occasionally dry islands. On the south it is bounded by the Everglades, through which the Indians pass in canoes to the great cooutie-grounds on the Atlantic, south of the Miami River. This is a belt from five to eight miles in width and twenty miles long. To travel directly through the swamp to the Everglades from Fort Keas, which is upon the north margin, the distance is about thirty miles. Directly south of the fort, in the heart of the swamp, is the council-ground. South-east and south-west from this are the towns of the principal chiefs, Sam Jones living twenty-five miles and the Prophet within two miles of him. Trails communicate with their towns, but none with Fort Keas, the Indians knowing that would be the first point to which the whites would come. The entrance from the pine barrens to the swamp is twenty miles farther south-east. Within the swamps are many high pine islands, upon which the villages are located, being susceptible of cultivation. Between them is a cypress swamp, with water two or three feet deep. Many have cultivated outside toward Lake Thompson, as the fertility of soil and sun-exposure insured better crops. The first reliance of the Indians is on their crop--peas, pumpkins, corn, and beans; next, roots, cooutie, and berries. They are now, in a measure, deprived of game, the powder being retained in the hands of their chiefs for defensive movements. When troops are in the vicinity, they reveal their hiding-place by firing guns, which, in a country so marshy, can be heard a great distance. Their babies never cry when the whites are near, but, as if by instinct, crawl away and hide in the long grass like partridges. Fish, when the streams on the coast can be reached, afford them subsistence, but the movements of the troops deprive them of this luxury. Among them are a large number of horses, ponies, some hogs, and a few cattle. The dry goods obtained from the massacre of Colonel Harney's men, and bartered by others who obtained a large quantity, clothe them richly as they desire. The specie has been sold, and manufactured into head-bands, breast-plates, or gorgets and bracelets. Among those Indians I have seen more rich ornaments than among any other Indians in Florida. Even in this murderous and lamentable massacre, when they all stood by each other, shoulder to shoulder, the same avarice and selfishness governed their actions. No feeling of friendship binds them to each other but the feudatory of Sam Jones and the necromancy of the Prophet.
