Who is that child I see wandering

Who is that child I see wandering, wandering
down by the side of the quivering stream?
Why does he seem not to hear, though I call to him?
Where does he come from, and what is his name?
Why do I see him at sunrise and sunset
taking, in old-fashioned clothes, the same track?
Why, when he walks, does he cast not a shadow
though the sun rises and falls at his back?
Why does the dust lie so thick on the hedgerow
by the great field where a horse pulls the plough?
Why do I see only meadows, where houses
stand in a line by the riverside now?
Why does he move like a wraith by the water,
soft as the thistledown on the breeze blown?
When I draw near him so that I may hear him,
why does he say that his name is my own?
