Two Pewits

UNDER the after-sunset sky Two pewits sport and cry, More white than is the moon on high Riding the dark surge silently; More black than earth. Their cry Is the one sound under the sky. They alone move, now low, now high, And merrily they cry To the mischievous Spring sky, Plunging earthward, tossing high, Over the ghost who wonders why So merrily they cry and fly, Nor choose 'twixt earth and sky, While the moon's quarter silently Rides, and earth rests as silently.
