It was a clear day in September. The boisterous winds which had swept the wide Canadian plain all summer had fallen and only a faint breeze stirred the yellowing leaves of the poplars. Against the glaring blue of the northern sky the edge of the prairie cut in a long, straight line; above the southern horizon rounded cloud-masses hung, soft and white as wool. Far off, the prairie was washed with tints of delicate gray, but as it swept in to the foreground the color changed, growing in strength, to brown and ocher with streaks of silvery brightness where the withered grass caught the light. To the east the view was broken, for the banks of a creek that wound across the broad level were lined with timber-birches and poplars growing tall in the shelter of the ravine and straggling along its crest. Their pale-colored branches glowed among the early autumn leaves.
