Suppose this slouching, scowling monster _did_ know anything? For a minute or two then Raut was really afraid for his life, but the mood passed as he reasoned with himself. After all, Horrocks might have heard nothing. At any rate, he had pulled him out of the way in time. His odd manner might be due to the mere vague jealousy he had shown once before. He was talking now of the ash-heaps and the canal. “Eigh?” said Horrocks. “What?” said Raut. “Rather! The haze in the moonlight. Fine!” “Our canal,” said Horrocks, stopping suddenly. “Our canal by moonlight and firelight is an immense effect. You’ve never seen it? Fancy that! You’ve spent too many of your evenings philandering up in Newcastle there. I tell you, for real florid effects—But you shall see. Boiling water . . .” As they came out of the labyrinth of clinker-heaps and mounds of coal and ore, the noises of the rolling-mill sprang upon them suddenly, loud, near, and distinct. Three shadowy workmen went by and touched their caps to Horrocks. Their faces were vague in the darkness. Raut felt a futile impulse to address them, and before he could frame his words, they passed into the shadows. Horrocks pointed to the canal close before them now: a weird-looking place it seemed, in the blood-red reflections of the furnaces. The hot water that cooled the tuyeres came into it, some fifty yards up—a tumultuous, almost boiling affluent, and the steam rose up from the water in silent white wisps and streaks, wrapping damply about them, an incessant succession of ghosts coming up from the black and red eddies, a white uprising that made the head swim. The shining black tower of the larger blast-furnace rose overhead out of the mist, and its tumultuous riot filled their ears. Raut kept away from the edge of the water, and watched Horrocks. “Here it is red,” said Horrocks, “blood-red vapour as red and hot as sin; but yonder there, where the moonlight falls on it, and it drives across the clinker-heaps, it is as white as death.” Raut turned his head for a moment, and then came back hastily to his watch on Horrocks. “Come along to the rolling-mills,” said Horrocks. The threatening hold was not so evident that time, and Raut felt a little reassured. But all the same, what on earth did Horrocks mean about “white as death” and “red as sin?” Coincidence, perhaps?
