"In this Plate, representing a numerous group in motion, and closely pursued by a party of Indians, with Lances and Bows, there is a fair illustration of the peculiar character of a vast deal of the rolling prairies in the great plains towards the Rocky Mountains; and which, by a phrase of the country, denominated Prairie Bluffs. These conical hills, which often rise to the height of several hundred fret, sometimes continuing in ranges and in regular succession, for a great number of miles, like tremendous waves of the ocean, are everywhere divested of timber sad shrubbery, and covered with a short grass; and during the spring and summer months, watered by frequent showers robbing them constantly with the most intense and verdant green. These are the most favorite haunts of the buffaloes; and when hotly pursued they will often seek the highest summits to avoid the approach, of their enemies; but even there, at seen in the illustration, the sinewy wild horse will carry his rider by their sides, where death is as inevitable as upon the level ground."
