All day he went over the fields, greeting some farmer here and there, or worker in the field, and gaining greetings in return, and good wishes for sport. But when evening came and he was near the frontier, fewer and fewer greeted him as he passed, for he was manifestly travelling where none went, whence even their thoughts held back. So he went lonely, yet cheered by his eager thoughts, and happy in the comradeship of his hounds; and both his thoughts and his hounds were all for the chase. And so he came to the barrier of twilight again, where the hedges ran down to it from the fields of men and turned strange and dim in a glow that is not of our Earth and disappeared in the twilight. He stood with his hounds close in against one of these hedges just where it touched the barrier. The light just there on the hedge, if like anything of our Earth, was like the misty dimness that flashes upon a hedge, seen only across one field, when touched by the rainbow: in the sky the rainbow is clear, but close across one wide field the rainbow's end scarcely shows, yet a heavenly strangeness has touched and altered the hedge. In some such light as that glowed the last of the hawthorns that grew in the fields of men. And just beyond it, like a liquid opal, all full of wandering lights, lay the barrier through which no man can see, and no sound come but the sound of the elfin horns, and only that to the ears of very few. The horns were blowing now, piercing that barrier of dim light and silence with the magical resonance of their silver note, that seemed to beat past all things intervening to come to Orion's ear, as the sunlight beats through ether to illumine the vales of the moon. The horns died down, and nothing whispered from Elfland; and all the sounds thenceforth were the sounds of an earthly evening. Even these grew few, and still no unicorns came.
