When the fast and purification was complete, they were compelled to set forth, prepared or unprepared, be the weather fair or foul. Accordingly, when the time arrived, they fired their guns, whooped, and danced, and sung--and continued firing their guns before them on the commencement of their route. The leading war-chief marched first, carrying their medicine bag, or budget of holy things. The rest followed in Indian file, at intervals of three or four paces behind each other, now and then chiming the war-whoop in concert. They advanced in this order until they were out of sight and hearing of the village. As soon as they reached the deep woods, all became as silent as death. This silence they inculcate, that their ears may be quick to catch the least portent of danger. Every one acquainted with the race, has remarked their intense keenness of vision. Their eyes, for acuteness, and capability of discerning distant objects, resemble those of the eagle or the lynx; and their cat-like tread among the grass and leaves, seems so light as scarcely to shake off the dew drops. Thus they advance on their expedition rapidly and in profound silence, unless some one of the party should relate that he has had an unpropitious dream When this happens, an immediate arrest is put upon the expedition, and the whole party face about, and return without any sense of shame or mortification. A whole party is thus often arrested by a single person; and their return is applauded by the tribe, as a respectful docility to the divine impulse, as they deem it, from the Great Spirit. These dreams are universally reverenced, as the warnings of the guardian spirits of the tribe. There is in that country a sparrow, of an uncommon species, and not often seen. This bird is called in the Shawnese dialect by a name importing "kind messenger," which they deem always a true omen, whenever it appears, of bad news. They are exceedingly intimidated whenever this bird sings near them; and were it to perch and sing over their war-camp, the whole party would instantly disperse in consternation and dismay. Every chief has his warrior, Etissu, or waiter, to attend on him and his party. This confidential personage has charge of every thing that is eaten or drank during the expedition. He parcels it out by rules of rigid abstemiousness. Though each warrior carries on his back all his travelling conveniences, and his food among the rest, yet, however keen the appetite sharpened by hunger, however burning the thirst, no one dares relieve his hunger or thirst, until his rations are dispensed to him by the Etissu. Boone had occasion to have all these rites most painfully impressed on his memory; for he was obliged to conform to them with the rest. One single thought occupied his mind--to seize the right occasion to escape.
