And many a day passed thus. And then one dewy morning, coming over a ridge of the downs, they saw a stag below them feeding late when all the rest were gone. The hounds all broke into one joyous cry, the heavy stag moved nimbly over the grass, Orion shot an arrow and missed; all these things happened in a moment. And then the hounds streamed away, and the wind went over the backs of them with a ripple, and the stag went away as though every one of his feet were on little dancing springs. And at first the hounds were swifter than Orion, but he was as tireless as they, and by taking sometimes shorter ways than theirs he stayed near them till they came to a stream and faltered and began to need the help of human reason. And such help as human reason can give in such a matter Orion gave them, and soon they were on again. And the morning passed as they went from hill to hill, and they had not seen the stag a second time; and the afternoon wore away, and still the hounds followed every step of the stag with a skill as strange as magic. And towards evening Orion saw him, going slowly, along the slope of a hill, over coarse grass that was shining in the rays of the low sun. He cheered on his hounds and they ran him over three more small valleys, but down at the bottom of the third he turned round amongst the pebbles of a stream and waited there for the hounds. And they came baying round him, watching his brow antlers. And there they tore him down and killed him at sunset. And Orion wound his horn with a great joy in his heart: he wanted no more than this. And with a note like that of joy, as though they also rejoiced, or mocked his rejoicing, over hills that he knew not, perhaps from the far side of the sunset, the horns of Elfland answered. CHAPTER XVII _The Unicorn Comes in the Starlight_ And winter came, and whitened the roofs of Erl, and all the forest and uplands. And when Orion took his hounds afield in the morning the world lay like a book that was newly written by Life; for all the story of the night before lay in long lines in the snow. Here the fox had gone and there the badger, and here the red deer had gone out of the wood; the tracks led over the downs and disappeared from sight, as the deeds of statesmen, soldiers, courtiers and politicians appear and disappear on the pages of history. Even the birds had their record on those white downs, where the eye could follow each step of their treble claws, till suddenly on each side of the track would appear three little scars where the tips of their longest feathers had flicked the snow, and there the track faded utterly. They were like some popular cry, some vehement fancy, that comes down on a page of history for a day, and passes, leaving no other record at all except those lines on one page.
