When the campaign was undertaken in prairie or open country, the method usually employed was that of night attack; but if for any reason this could not be successfully made, a large circle was drawn round the place to be assailed, and gradually narrowed, the warriors who composed it creeping and wriggling through the grass, and when sufficiently near rising and rushing the camp or fort with wild war-cries. If a stout defence with firearms was anticipated, the warriors would surround the objective of attack on horseback, and ride round and round the fated position, gradually picking off the defenders with their rifles or arrows as the opportunity presented itself. Once the place was stormed the Indian brave neither asked nor gave quarter, at least so far as its male defenders were concerned. These were at once slain and scalped, the latter sanguinary process being effected by the brave placing his knees on his enemy's shoulders, describing a rapid circle with his knife in the centre of the victim's head, seizing the portion of the scalp thus loosened, and quickly detaching it.

[[16]] Historical and Statistical Information respecting the Indian Tribes.

"Success in war is to the Indian the acme of glory, and to learn its arts the object of his highest attainment. The boys and youths acquire the accomplishment at an early period of dancing the war-dance; and although they are not permitted to join its fascinating circle till they assume the envied rank of actual warriors, still their early sports and mimic pastimes are imitations of its various movements and postures. The envied eagle's feather is the prize. For this the Indian's talent, subtlety, endurance, bravery, persevering fasts, and what may be called religious penances and observances are made.

"The war-path is taken by youths at an early age. That age may be stated, for general comparison, to be sixteen; but, without respect to exact time, it is always after the primary fast, during which the youth chooses his personal guardian or monedo—an age when he first assumes the duties of manhood. It is the period of the assumption of the three-pointed blanket, the true toga of the North American Indian.

"The whole force of public opinion, in our Indian communities, is concentrated on this point; its early lodge teachings (such as the recital of adventures of bravery), its dances, its religious rites, the harangues of prominent actors, made at public assemblages (such as is called 'striking the post'), all, in fact, that serves to awaken and fire ambition in the mind of the savage, is clustered about the idea of future distinction in war.

"... The Indian has but one prime honour to grasp; it is triumph in the war-path; it is rushing upon his enemy, tearing the scalp reeking from his head, and then uttering his terrific sa-sa-kuon (death-whoop). For this crowning act he is permitted to mount the honoured feather of the war-eagle—the king of carnivorous birds. By this mark he is publicly known, and his honours recognized by all his tribe, and by the surrounding tribes whose customs assimilate.

"When the scalp of an enemy has been won, very great pains are taken to exhibit it. For this purpose it is stretched on a hoop and mounted on a pole. The inner part is painted red, and the hair adjusted to hang in its natural manner. If it be the scalp of a male, eagle's feathers are attached to denote that fact. If a female, a comb or scissors is hung on the frame. In this condition it is placed in the hands of an old woman, who bears it about in the scalp-dance, while opprobrious epithets are uttered against the tribe from which it was taken. Amidst these wild rejoicings the war-cry is vociferated, and the general sentiment with old and young is: 'Thus shall it be done to our enemies.'

"The feather of the eagle is the highest honour that a warrior can wear, and a very extravagant sum is sometimes given to procure one. The value of a horse has been known to be paid. The mode in which a feather is to be cut and worn is important to be noticed.
