Sea-ward, white gleaming thro' the busy scud (fragment)

Sea-ward, white gleaming thro' the busy scud
 With arching Wings, the sea-mew o'er my head
 Posts on, as bent on speed, now passaging
 Edges the stiffer Breeze, now, yielding, drifts,
 Now floats upon the air, and sends from far
 A wildly-wailing Note.
