WHO?

1ST STRANGER.WHO walks with us on the hills?
2ND STRANGER.I cannot see for the mist.
3RD STRANGER.Running water I hear,
Keeping lugubrious tryst
With its cresses and grasses and weeds,
In the white obscure light from the sky.
2ND STRANGER.Who walks with us on the hills?
WILD BIRD.Ay!... Aye!... Ay!...
