Evening by Percy Bysshe Shelley River poem

The sun is set; the swallows are asleep;
The bats are flitting fast in the gray air;
The slow soft toads out of damp corners creep;
And evening’s breath, wandering hero and there
Over the quivering surface of the stream,
Wakes not one ripple from its summer dream.

There is no dew on the dry grass to-night,
Nor damp within the shadow of the trees;
The wind is intermitting, dry, and light;
And in the inconstant motion of the breeze
The dust and straws are driven up and down,
And whirled about the pavement of the town.

Within the surface of the fleeting river
The wrinkled image of the city lay,
Immovably unquiet, and forever
It trembles, but it never fades away.
