Alan Sullivan,
Out of the Pit
(1922)
“ Slowly along the smooth floor of the chamber came the first breathings of gas. From ruptured fissures and innumerable crevices in the shattered earth it crept. Heavy with portent, it flooded the broken coal about the men's feet. No life-giving breath could penetrate the mountain of fallen rock to dissipate these deadly fumes. At last they both knew it. Don began to ramble, talking now to Nan, now to Jock, and bursting into sudden heartrending appeals for help. Somewhere on the other side of that barrier men were fighting viciously to get at them and drag them up to sunlight. ”
