At intervals during all this time Tokulki had seen bands of warriors, including sometimes his father and uncles, march out against their enemies, and in particular there was an enemy to the westward, not large in numbers but led by a chief of rare size, strength, and sagacity, whose activities were constantly more threatening, and who was aided and abetted by a much more numerous people beyond him called Long Hairs. At last, raids from this quarter became so numerous and so many injuries were suffered that a great council was held in Tulsa and it was determined to draw their settlements closer together and erect a strong stockade about them. Tokulki, although still too young for the heavier work, was called upon to render such assistance as he could in the completion of the structure. While the older men marked out the course of the wall and planted in the ground good-sized tree trunks a few feet apart, Tokulki and the other young men brought together numbers of long, flexible branches or young trees which they wove from one post to another, covering the whole with a plastering of mud. About a hundred feet apart little watchtowers were raised above the top of the wall, projecting forward slightly in order to defend the intervening spaces against attempts of an enemy to scale or burn them. On the river side there was but one row of palisades, but elsewhere it was doubled. Toward the river, too, was the only opening, made by allowing the walls slightly to overlap. To approach this an enemy must creep along a narrow path between wall and water, exposed to certain death should he be discovered.
