On the evening of both days which our Kaskaia spent with us, we observed him to commence soon after sunset a monotonous and somewhat melancholy song, which he continued for near an hour. He gave us some account of a battle which had lately been fought between the Tabba-boos (Anglo-Americans) and the Spaniards, in which great guns had been used, and when the Spaniards, though superior in number, had been beaten. He appeared well acquainted with the use of fire-arms, and challenged one of the party to a trial of skill in shooting at a mark with the rifle. He had a fusee, kept very carefully in a case of leather, and carried, when travelling, by his squaw. He was also armed with a bow and some light arrows for hunting, which he carried constantly in his hand. He took his leave of us on the morning of the 23d, having received several presents, with which he appeared highly pleased. The Arkansa, between this point and the mountains, has a rapid current, whose velocity probably varies from five to six miles per hour. It may be forded at many places in a moderate stage of water. The average breadth of the river is from sixty to seventy-five yards; at many places, however, it is much enlarged, including numerous islands. It pursues a remarkably serpentine course within its valley, forming a succession of points on both sides of the river; which, together with the islands, are usually covered with cotton-wood. The bed of the river is gravelly, or composed of waterworn stones, which diminish in size as you recede from the mountains. The water is turbid, but in a less remarkable degree than that of the Platte. The bed of the river has, in many instances, changed its place; and the old {255} channel is sometimes occupied by stagnant water, and sometimes by a small stream, which is rendered transparent by passing through the sand and gravel, forming the recently-raised bank of the river. On the 24th the movements of the party were resumed. Major Long, with the division destined to Red river, crossed the Arkansa at five A. M. On arriving at the opposite bank three cheers were given, which our late companions returned from the other side. We lost sight of them as they were leaving the camp to descend the Arkansa. The party, consisting of ten men, took with them six horses and eight mules, most of them in good condition for travelling. A few had sore backs, but one horse only was unfit for service.
