The wall is built of field stones great and small,
Tumbled about by frost and storm,
Shaped and polished by ice and rain and sun;
Some flattened, grooved, and chiseled
By the inscrutable sculpture of the weather;
Some with clefts and rough edges harsh to the touch.
Gracious Time has glorified the wall
And covered the historian stones with a mantle of green;
The sunbeams flit and waver in the rifts,
Vanish and reappear, linger and sleep,
Conquer with radiance the obdurate angles,
Filter between the naked rents and wind-bleached jags. (The Song of the Stone Wall)
