We now drew upon our little store of merchandize, for two or three twists of tobacco and a few knives, which, being laid before the partizan, excited from his politeness the return of thanks. He was of an ordinary stature, and had exceeded the middle age; his face much pitted with the small pox, his nostrils distended by a habitual muscular action, which at the same time elevated the skin of the forehead, and forcibly drew downward that part which corresponds with the inner extremity of the eyebrows, into a kind of gloomy frown. This singular expression of countenance, added to the contrast of the whites of his large eyes, with the black colour with which his features and body were overspread, seemed to indicate the operations of a mind hardened to the commission of the most outrageous actions. He however behaved with much propriety. During these scenes Mr. Say succeeded in ascertaining and recording many of the words of the language, from an Indian who had seated himself behind him. The party was armed with spears, bows, and arrows, war-clubs, tomahawks, scalping knives, &c. As many of them now began to ask for tobacco and for paper, to include fragments of it in the form of segars for smoking, and not finding it convenient to gratify them in this respect, we thought it prudent to withdraw, lest a quarrel might ensue. We therefore mounted our horses without molestation, having been detained an hour and a half, and proceeded on our journey, with the agreeable reflection that our deportment had not warranted a supposition that we were conscious of any inferiority in force, but rather that it was dictated by a high courtesy. A few bisons varied the landscape, which is fatiguing to the eye by its sameness; and after travelling twenty-three miles, we encamped for the night. A {63} large green-headed fly (tabanus) has made its appearance in great numbers, which exceedingly worries our already sufficiently miserable horses. Their range seems to be in a great measure restricted to the luxuriant bottoms, and, like the zimb of Egypt, they appear to roam but little beyond their proper boundaries. If we traversed these fertile portions of the low grounds, which yield a profuse growth of grasses, we were sure of being attacked by them, seizing upon the necks of the horses, and dyeing them with blood; but the refuge of the more elevated surface, and arid barren soil, afforded speedy relief, by banishing our assailants. Scarcely were our tents pitched, when a thunder-storm, which had been approaching with a strong west wind, burst over us, but was of short continuance.
