But his horn had passed the boundary's edge and troubled the air of Elfland, uttering across its dreamy calm one long sad earthly note: it was the horn that Lirazel heard as she spoke with her father. CHAPTER XXVII _The Return of Lurulu_ Over hamlet and Castle of Erl, and through every nook and crevice of it, Spring passed; a mild benediction that blessed the very air and sought out all living things; not missing even the tiny plants that had their dwelling in most secluded places, under eaves, in the cracks of old barrels, or along the lines of mortar that held ancient rows of stones. And in this season Orion hunted no unicorns; not that he knew in what season the unicorns bred in Elfland, where time is not as here; but because of a feeling he had from all his earthly forefathers against hunting any creature in this season of song and flowers. So he tended his hounds and often watched the hills, expecting on any day the return of Lurulu. And Spring passed by and the Summer flowers grew, and still there was no sign of the troll returning, for time moves through the dells of Elfland as over no field of man. And long Orion watched through fading evenings till the line of the hills was black, yet never saw the small round heads of trolls bobbing across the downs. And the long autumnal winds came sighing out of cold lands, and found Orion still watching for Lurulu; and the mist and the turning leaves spoke to his heart of hunting. And the hounds were whining for the open spaces and the line of scent like a mysterious path crossing the wide world, but Orion would hunt nothing less than unicorns, and waited yet for his trolls. And one of these earthly days, with a menace of frost in the air and a scarlet sunset, Lurulu's talk to the trolls in the wood being finished, and their scamper swifter than hares having brought them soon to the frontier, those in our fields who looked (as they seldom did) towards that mysterious border where Earth ended might have seen the unwonted shapes of the nimble trolls coming all grey through the evening. They came dropping, troll after troll, from the soaring leaps they took high through the boundary of twilight; and, landing thus unceremoniously in our fields, came capering, somersaulting and running, with gusts of impudent laughter, as though this were a proper manner in which to approach by no means the least of the planets.
