to step over his blanket, gun, tomahawk, or anything that belonged to him. If this rule was inadvertently broken, it became the duty of the member whose person or property had been stepped over to knock the other member down, and it was similarly the duty of that other to be knocked down peaceably and without resistance. The vessels out of which the warriors ate their food were commonly small bowls of wood or birch bark, with marks to distinguish the two sides; in marching from home the Indians invariably drank out of one side of the bowl, and in returning they drank out of the other. When on their way home they came within a day’s march of the village, they hung up all their bowls on trees, or threw them away on the prairie,(551) doubtless to prevent their sanctity or defilement from being communicated with disastrous effects to their friends, just as we have seen that the vessels and clothes of the sacred Mikado, of women at childbirth and menstruation, of boys at circumcision, and of persons defiled by contact with the dead are destroyed or laid aside for a similar reason. The first four times that an Apache Indian goes out on the war-path, he is bound to refrain from scratching his head with his fingers and from letting water touch his lips. Hence he scratches his head with a stick, and drinks through a hollow reed or cane. Stick and reed are attached to the warrior’s belt and to each other by a leathern thong.(552) The rule not to scratch their heads with their fingers, but to use a stick for the purpose instead, was regularly observed by Ojebways on the war-path.(553)
