I too many and many a time cross’d the river of old,
Watched the Twelfth-month sea-gulls, saw them high in the air floating with motionless wings, oscillating their bodies,
Saw how the glistening yellow lit up parts of their bodies and left the rest in strong shadow,
Saw the slow-wheeling circles and the gradual edging toward the south
