G. Hartwig, The Subterranean World
“ Go where you will, tall chimneys rise up before you, and here and there a low line of black sheds, flanked by chimneys of aspiring altitude, indicates that you are arriving at a colliery. As you draw nearer, men and boys of blackest hue pass you and peer at you with inquiring glances. Now trains of coal-waggons rush by more frequently, noises of the most discordant character increase, and you know that you are at the pit’s mouth, when you behold two gigantic wooden arms slanting upwards, upon which are mounted the pulleys and wheels that carry the huge flat wire ropes of the shaft. ”
