“Certainly you get some fine effects of colour with your furnaces,” said Raut, breaking a silence that had become apprehensive. Horrocks grunted. He stood with his hands in his pockets, frowning down at the dim steaming railway and the busy ironworks beyond, frowning as if he were thinking out some knotty problem. Raut glanced at him and away again. “At present your moonlight effect is hardly ripe,” he continued, looking upward; “the moon is still smothered by the vestiges of daylight.” Horrocks stared at him with the expression of a man who has suddenly awakened. “Vestiges of daylight! Of course, of course.” He too looked up at the moon, pale still in the midsummer sky. “Come along,” he said suddenly, and, gripping Raut’s arm in his hand, made a move towards the path that dropped from them towards the railway. Raut hung back. Their eyes met and saw a thousand things in a moment that their lips came near to say. Horrocks’s hand tightened and then relaxed. He left go, and before Raut was aware, they were arm in arm, and walking, one unwillingly enough, down the path. “You see the fine effect of the railway signals towards Burslem,” said Horrocks, suddenly breaking into loquacity, striding fast and tightening the grip of his elbow the while. “Little green lights and red and white lights, all against the haze. You have an eye for effect, Raut. It’s a fine effect. And look at those furnaces of mine, how they rise upon us as we come down the hill. That to the right is my pet—seventy feet of him. I packed him myself, and he’s boiled away cheerfully with iron in his guts for five long years. I’ve a particular fancy for _him_. That line of red there,—a lovely bit of warm orange you’d call it, Raut,—that’s the puddler’s furnaces, and there, in the hot light, three black figures—did you see the white splash of the steam hammer then?—that’s the rolling mills. Come along! Clang, clatter, how it goes rattling across the floor! Sheet tin, Raut,—amazing stuff. Glass mirrors are not in it when that stuff comes from the mill. And, squelch!—there goes the hammer again. Come along!” He had to stop talking to catch at his breath. His arm twisted into Raut’s with benumbing tightness. He had come striding down the black path towards the railway as though he was possessed. Raut had not spoken a word, had simply hung back against Horrocks’s pull with all his strength. “I say,” he said now, laughing nervously, but with an undernote of snarl in his voice, “why on earth are you nipping my arm off, Horrocks, and dragging me along like this?” At length Horrocks released him. His manner changed again. “Nipping your arm off!” he said. “Sorry. But it’s you taught me the trick of walking in that friendly way.”
