been given, and of which more will be adduced shortly. (M122) In the late autumn or early winter a few families of the Hidatsa Indians seek some quiet spot in the forest and pitch their camp there to catch eagles. After setting up their tents they build a small medicine-lodge, where the ceremonies supposed to be indispensable for trapping the eagles are performed. No woman may enter it. The traps are set on high places among the neighbouring hills. When some of the men wish to take part in the trapping, they fast and then go by day to the medicine-lodge. There they continue without food until about midnight, when they partake of a little nourishment and fall asleep. They get up just before dawn, or when the morning-star has risen, and go to their traps. There they sit all day without food or drink, watching for their prey, and struggling, it may be, from time to time with a captive eagle, for they always take the birds alive. They return to the camp at sunset. As they approach, every one rushes into his tent; for the hunter may neither see nor be seen by any of his fellow-hunters until he enters the medicine-lodge. They spend the night in the lodge, and about midnight eat and drink for the first time since the previous midnight; then they lie down to sleep, only to rise again before dawn and repair anew to the traps. If any one of them has caught nothing during the day, he may not sleep at night, but must spend his time in loud lamentation and prayer. This routine has to be observed by each hunter for four days and four nights, after which he returns to his own tent, hungry, thirsty, and tired, and follows his ordinary pursuits till he feels able to go again to the eagle-traps. During the four days of the trapping he sees none of his family, and speaks to none of his friends except those who are engaged in the trapping at the same time. They believe that if any hunter fails to perform all these rites, the captive eagle will get one of his claws loose and tear his captor’s hands. There are men in the tribe who have had their hands crippled for life in that way.(655) It is obvious that the severe fasting coupled with the short sleep, or even the total sleeplessness, of these eagle-hunters can only impair their physical vigour and so far tend to incapacitate them for capturing the eagles. The motive of their behaviour in these respects is purely superstitious, not rational, and so, we may safely conclude, is the custom which simultaneously cuts them off from all intercourse with their wives and families.
