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.
