Do you know where it is -- the Hollow Land?

I have been looking for it now so long, trying to find it again -- the Hollow Land -- for there I saw my love first.

I wish to tell you how I found it first of all; but I am old, my memory fails me: you must wait and let me think if I perchance can tell you how it happened. Yea, in my ears is a confused noise of trumpet-blasts singing over desolate moors, in my ears and eyes a clashing and clanging of horse-hoofs, a ringing and glittering of steel; drawn-back lips, set teeth, shouts, shrieks, and curses. . . .
