In a brown mass thicker than young pigs are along the edge of a trough the trolls encumbered the floor of the pigeons' home. And time went over them as over all earthly things. And well they knew, though tiny was their intelligence, that by crossing the border of twilight they incurred the wasting of time; for nothing dwells by the brink of any danger and lives ignorant of its menace: as conies in rocky altitudes know the peril of the sheer cliff, so they that dwell near Earth's border knew well the danger of time. And yet they came. The wonder and lure of Earth had been overstrong for them. Does not many a young man squander youth as they squandered immortality? And Lurulu showed them how to hold off time for a while, which otherwise would make them older and older each moment and whirl them on with Earth's restlessness all night long. Then he curled up his knees and shut his eyes and lay still. This, he told them, was sleep; and, cautioning them to continue to breathe, though being still in other respects, he then slept in earnest: and after some vain attempts the brown trolls did the same. When sunrise came, awaking all earthly things, long rays came through the thirty little windows and awoke both birds and trolls. And the mass of trolls went to the windows to look at Earth, and the pigeons fluttered to rafters and jerked sidelong looks at the trolls. And there that heap of trolls would have stayed, crowded high on each other's shoulders, blocking the windows while they studied the variety and restlessness of Earth, finding them equal to the strangest fables that wayfarers had brought to them out of our fields; and, though Lurulu often reminded them, they had forgotten the haughty white unicorns that they were to hunt with dogs. But Lurulu after a while led them down from the loft and brought them to the kennels. And they climbed up the high palings and peered over the top at the hounds. When the hounds saw those strange heads peering over the palings they made a great uproar. And presently folk came to see what troubled the hounds. And when they saw that mass of trolls all round the top of the palings they said to each other, and so said all that heard of it: "There is magic in Erl now." CHAPTER XXVIII _A Chapter on Unicorn-Hunting_ None in Erl was so busy but that he came that morning to see the magic that was newly come out of Elfland, and to compare the trolls with all that the neighbours said of them. And the folk of Erl gazed much at the trolls and the trolls at the folk of Erl, and there was great merriment; for, as often happens with minds of unequal weight, each laughed at the other. And the villagers found the impudent ways of the bare brown nimble trolls no funnier, no more meet for derision, than the trolls found the grave high hats, the curious clothes, and the solemn air of the villagers.
