The body is slender, and the tail rather long, cylindrical, and black. It runs with extraordinary swiftness, so much so, that when at full speed, its course has been by the hunters compared to the flight of a bird skimming the surface of the earth. We had opportunities of seeing it run with the antelope; and appearances sanctioned the belief, that in fleetness it even exceeded that extraordinary animal, famed for swiftness, and for the singularity of its horns. Like the corsac of Asia it burrows in the earth, in a country totally destitute of trees or bushes, and is not known to dwell in forest districts. If Buffon's figure of the corsac is to be implicitly relied upon, our burrowing fox must be considered as perfectly distinct, and anonymous; we would, therefore, propose for it the name of _velox_.—JAMES. Our small stock of bread was by this time so nearly exhausted, that it was thought prudent to reserve the remainder as a last resort, in case of the failure of a supply of game, or other accident. A quantity of parched maize, equal to a gill per day, to each man, was daily distributed to each of the three messes into which the party was divided. This was thrown into the kettle where the bison meat was boiled, and supplied the place of barley in the soup, always the first and most important dish. Whenever game was plenty we had a variety of excellent dishes, consisting of the choice parts of the bison, the tongue, the hump ribs, the marrow-bones, &c. dressed in various ways. The hump ribs of the bison, which many epicures prefer to any other part of the animal, are the spinous processes of the backbone, and are from eighteen to twenty-four inches in length. They are taken out with a small portion of the flesh adhering to each side, and whether roasted, boiled, or stewed, are certainly very far superior to any part of the flesh of the domestic ox. 29th. We had proceeded but a few miles from our camp when it was found that Mr. Say's horse was so far exhausted as to be unable to proceed at the same pace as the other horses. Mr. Say accordingly dismounted, and by driving his horse before him, urged the animal along for a few miles; but this being found too laborious, and as several of the horses were near failing, it was determined to halt, which we did at ten o'clock, and remained in camp during the day.
