At the end of a day's march the wagon-master, or "wagon-boss," who always rode ahead of the train mounted on a sleek saddle mule, would select a camping-ground, generally where wood, water, and grass were to be had, and, turning from the beaten trail, would lead the way to it. Where he halted the first wagon also stopped. Then he would move on a short distance, and the second wagon would follow him, until it was ordered to wheel into line with the first. When all thus occupied their designated positions, they either formed a semicircle on the bank of the stream, with their poles pointing inward, were arranged in two parallel lines facing each other, or, if the place was very much exposed, they would form a complete circle, with each tongue overlapping the hind-wheels of the wagon before it.
