The friend, after listening to all this, if the affair seems promising, will take to the drum in his turn, and aid his friend with his dreams. The latter, if placing full confidence in him, appoints him his associate or adjutant, and both place themselves at the head of the undertaking. They always consider it better that there should be two leaders, in order that if the dreams of one have not strength enough the other may help him out. These two _chefs-de-guerre_ now sit together the whole winter through, smoke countless pipes, beat the drum in turn, mutter magic songs the whole night, consult over the plan of operations, and send tobacco to their friends as an invitation to them to take part in the campaign. The winter is the season of consultation, for war is rarely carried on then, partly because the canoe could not be employed on the frozen lakes, and partly because the snow would betray their trail and the direction of their march too easily. If the two are agreed on all points, if they have assembled a sufficient number of recruits and allies, and have also settled the time of the foray--for instance, arranged that the affair shall begin when the leaves are of such a size, or when such a tree is in blossom, and this time has at length arrived, they first arrange a universal war dance with their relatives and friends, at which the women are present, painted black like the men. The squaws appear at it with dishevelled hair, and with the down of the wild duck strewn over their heads. A similar war dance is also performed in the lodges of all the warriors who intend to take part in the expedition. If the undertaking and the band of braves be at all important, it is usually accompanied by a maiden, whom they call “the squaw of sacrifice.” She is ordinarily dressed in white: among the Sioux, for instance, in a white tanned deer or buffalo robe, and a red cloth is wrapped round her head. Among several prairie tribes, as the Black-feet, this festally adorned sacrifice squaw leads a horse by the bridle, which carries a large medicine-bag, and a gaily decorated pipe. Among the Ojibbeways, who have no horses, and usually make their expeditions by water, this maiden is seated in a separate canoe. When all have taken their places in full war-paint, they begin their melancholy death-song and push off. If the expedition is really important--if the leader of the band is very influential--he will have sent tobacco to other chiefs among his friends; and if they accept it, and divide it among many of their partisans, other war bands will have started simultaneously from the villages, and come together at the place of assembly already arranged. They naturally take with them as little as possible, and are mostly half naked in order to march easily. They do not even burden themselves with much food, for they starve and fast along the road, not through any pressure of circumstances, but because this fasting is more or less a religious war custom.
