At last the air fragrant, the bird's bubbling whistle 
Succinct in the unknown unsettled trees: 
O little Charles, beside the Georgian colleges 
And milltown New England; at last the wind soft, 
The sky unmoving, and the dead look 
Of factory windows separate, at last, 
From windows gray and wet: 
                                            for now the sunlight 
Thrashes its wet shellac on brickwalk and gutter, 
White splinters streak midmorning and doorstep, 
Winter passes as the lighted streetcar 
Moves at midnight, one scene of the past, 
Droll and unreal, stiff, stilted and hooded.
Delmore Schwartz
