The only other sound's the sweep
Of easy wind and downy flake.
The narrator, on the other hand, hears the horse but doesn’t end his contemplation just yet. The easy wind, the “downy flake” (downy means feathery), is evocative of relaxation and rest. The sublime woods sing a siren song to the narrator, drawing him in. The impulse could lead to enjoyable ends, or it could be a deadly decision.
