The spring rains woke the dormant tillers, and bright green shoots sprang from the moist earth and rose like sleepers stretching after a long nap. As spring gave way to summer, the bright green stalks darkened, became tan, turned golden brown. The days grew long and hot. Thick towers of swirling black clouds brought rain, and the brown stems glistened in the perpetual twilight that dwelled beneath the canopy. The wheat rose and the ripening heads bent in the prairie wind, a rippling curtain, an endless, undulating sea that stretched to the horizon.
