The mowing machine’s whirring sounded cheerfully from the old buffalo wallow south of the claim shanty, where bluestem grass stood thick and tall and Pa was cutting it for hay. The sky was high and quivering with heat over the shimmering prairie. Half-way down to sunset, the sun blazed as hotly as at noon. The wind was scorching hot. But Pa had hours of mowing yet to do before he could stop for the night. Laura drew up a pailful of water from the well at the edge of the Big Slough. She rinsed the brown jug till it was cool to her hand. Then she filled it with the fresh, cool water, corked it tightly, and started with it to the hayfield. Swarms of little white butterflies hovered over the path. A dragon-fly with gauzy wings swiftly chased a gnat. On the stubble of cut grass the striped gophers were scampering. All at once they ran for their lives and dived into their holes. Then Laura saw a swift shadow and looked up at the eyes and the claws of a hawk overhead. But all the little gophers were safe in their holes.
