Upton Sinclair,
King Coal — Book III Chapter 17
(1917)
“ The helmet-men, coming up, reported that lights would burn at the bottom of the shaft; so it was safe for men to go down without helmets, and the volunteers of the first rescue party made ready. All night there had been a clattering of hammers, where the carpenters were working on a new cage. Now it was swung from the hoist, and the men took their places in it. When at last the hoist began to move, and the group disappeared below the surface of the ground, you could hear a sigh from a thousand throats, like the moaning of wind in a pine-tree. ”
