The situation of principal chief is very frequently usurped during the minority of the rightful successor, or wrested from an imbecile incumbent by some ambitious chief or warrior. In this case the ascendancy obtained over the nation by the usurper is gradual, and depends upon the resources of his own mind, aided by his reputation for generosity and valour. The condition of the savages is a state of constant alarm and apprehension. Their security from their enemies, and their means of subsistence, are precarious and uncertain, the former requiring the utmost vigilance to prevent its infraction, and the latter being attended with no regular supplies of the necessaries of life. In times of the most profound peace, whether at their villages or on a hunting expedition, they are continually on the alert lest they should be surprised by their enemies. By day scouts are constantly kept patrolling for a considerable distance around them, and by night sentinels are posted to give notice of the approach of strangers. {254} When they engage in a hunt, they generally abandon their villages, old men, women, and children joining in the enterprize, through fear of being left at home without the strength of their nation to protect them. On their march they endeavour to make as great a display of force as practicable, in order to intimidate any of their enemies that may be lurking to spy out their condition. With this view they are careful to pitch their lodges or tents at the places of their encampment in such a manner, and in such numbers, as to give the impression, at a distance, that they are numerous and formidable. We have witnessed a hunting party on their march, consisting of not more than one hundred persons, including men, women, and children, yet at their encampment more than thirty lodges were pitched, each of which would accommodate at least twelve adult persons.
