And many times again, while the winter wore away, Orion went back again with his hounds to that wonderful boundary, and waited there while the earthly twilight faded; and sometimes saw the unicorns come through, craftily, silently, when our fields were still, great beautiful shapes of white. But he brought back no more horns to the castle of Erl, nor hunted again across the fields we know; for the unicorns when they came moved into our fields no more than a few bare paces, and Orion was not able to cut one off again. Once when he tried he nearly lost all his hounds, some being already within the boundary when he beat them back with his whip; another two yards and the sound of his earthly horn could never more have reached them. It was this that taught him that for all the power that he had over his hounds, and even though in that power was something of magic, yet one man without help could not hunt hounds, so near to that edge over which if one should stray it would be lost forever. After this Orion watched the lads at their games in evenings at Erl, till he had marked three that in speed and strength seemed to excel the rest; and two of these he chose to be whippers-in. He went to the cottage of one of them when the games were over, just as the lights were lit, a tall lad with great speed of limb; the lad and his mother were there and both rose from the table as the father opened the door and Orion came in. And cheerily Orion asked the lad if he would come with the hounds and carry a whip and prevent any from straying. And a silence fell. All knew that Orion hunted strange beasts and took his hounds to strange places. None there had ever stepped beyond the fields we know. The lad feared to pass beyond them. His parents were full loth to let him go. At length the silence was broken by excuses and muttered sentences and unfinished things, and Orion saw that the lad would not come. He went then to the house of the other. There too the candles were lit and a table spread. There were two old women there and the lad at their supper. And to them Orion told how he needed a whipper-in, and asked the lad to come. Their fear in that house was more marked. The old women cried out together that the lad was too young, that he could not run so well as he used to, that he was not worthy of so great an honour, that dogs never would trust him. And much more than this they said, till they became incoherent. Orion left them and went to the house of the third. It was the same here. The elders had desired magic for Erl, but the actual touch of it, or the mere thought of it, perturbed the folk in their cottages. None would spare their sons to go whither they knew not, to have dealings with things that rumour, like a large and sinister shadow, had so grimly magnified in the hamlet of Erl. So Orion went alone with his hounds when he took them up from the valley and went eastwards over our fields where Earth's folk would not go.
