A party of travellers were wending their way across a wide-spreading prairie in the north-west territory of America. As far as the eye could reach, the ground was covered with waving tufts of dark-green grass, interspersed with flowers of varied hue, among which could be distinguished the yellow marigold and lilac bergamot, with bluebells, hare-bells, and asters, innumerable; while here and there rose-bushes, covered with gorgeous bloom, appeared above the particoloured carpet spread over the country. On the north side the prairie was bounded by softly rounded knolls, between which tiny lakelets were visible, shining in the bright rays of the glowing sun. To the northward a silvery stream could be seen meandering, bordered by willows, aspens, osiers, and other trees of considerable height, breaking the line of the horizon. "I am delighted with your country, Burnett; I had no idea such lovely scenery and so much rich soil existed on this side of the Rocky Mountains," said one of the travellers, addressing another, who rode alongside him.
