" Sometimes the drifts of smoke are rosy with sulphur, and serrated flames, like circular saws, squeeze themselves out from beneath the cowls of the foundry chimneys. Through the open doors of foundries you see fiery serpents of iron being hauled to and fro by redlit boys, and you hear the whizz and thump of steam hammers and the scream of the iron under the blow. "

― George Orwell
