On great pied motionless moth-wings borne along,
So effortless and so strong,
Cutting each other's paths, together they glided,
Then wheeled asunder till they soared divided
Two valleys' width (as though it were delight
To part like this, being sure they could unite
So swiftly in their empty, free dominion),
Curved           downward, towered up the sunny steep,
Then, with a sudden lift of the one great pinion,
Swung proudly to a curve and from its height
Took half a mile of sunlight in one long sweep.
