Watching the Swallows

Watching the swallows
That flew about restlessly,
And flung their shadows
Upon the sunbright walls of the old building;
The shadows glanced and twinkled,
Interchanged and crossed each other,
Expanded and shrunk up,
Appeared and disappeared, every instant;
As I observed to William and Coleridge,
Seeming more like living things
Than the birds themselves.
