Harriet Monroe - Wings

Pearl-gray is the sky,
And high within it, sailing by,
Three sea-gulls fly.

Pearl-white are they
Against the sky's obscurer gray—
Sea-foam astray.

Gulls, sea-gulls white,
Drift of the day, drift of the night,
Mine be your flight!

Out—out, with you
Beyond the noise, into the blue!
Ah—if I knew!

Harriet Monroe
