Monday, 14th. A slight dew had fallen; the wind was S.S.E., nearly calm; and our morning's journey was arduous, in consequence of the great heat of the atmosphere. Our dogs, these two or three days past, {77} had evidently followed us with difficulty. Cæsar, a fine mastiff, and the larger of the two, this morning trotted heavily forwards, and threw himself down directly before the first horse in the line; the rider turned his horse aside, to avoid doing injury to the dog; but had he noticed the urgency of this eloquent appeal of the animal for a halt, it would not have passed unregarded. The dog, finding this attempt to draw attention to his sufferings unavailing, threw himself successively before two or three other horses, but still failed to excite the attention he solicited, until a soldier in the rear observed that his respiration was excessively laborious, and his tongue to a great length depended from his widely extended mouth. He therefore took the dog upon his horse before him, intending to bathe him in the river, which, however, being at the distance of half a mile, the poor exhausted animal expired in his arms before he reached it. To travellers in such a country, any domesticated animal, however abject, becomes an acceptable companion; and our dogs, besides their real usefulness as guards at night, drew our attention in various ways during the day, and became gradually so endeared to us, that the loss of Cæsar was felt as a real evil. The afternoon continued sultry, the extreme heat being 97 degrees. Towards evening a brisk N. E. wind appeared to proceed from a nimbus which was pouring rain in that direction, and produced so instantaneous and great a change in the atmospheric temperature, that we were obliged to button up to the chin; but it refreshed and revived us all. As we were now approaching a well-wooded creek, we hoped soon to assuage our impatient thirst, but great was the mortification, upon arriving at the naked bank, to see a dry bed of gravel of at least fifty yards in breadth. Crossing this inhospitable tract, which appears to be occasionally deluged with water, with the intention of passing down the opposite bank to {78} the river, we were agreeably surprised to discover a fine limpid stream of cool flowing water, meandering through a dense growth of trees and bushes, which had before concealed it from view. Here we remarked the honey locust and button-wood (platanus occidentalis), though the principal growth was cotton-wood, elm, and ash. This stream of water, we believe, is known to a few hunters, who have had an opportunity to visit it, by the name of _Little Arkansa_.[112] The distance of the day's journey was twenty-three miles, during which but a single prairie dog village was seen, and proved to be the last one that occurred on the expedition. Partridges and prairie fowls were numerous.
