Francis Rolt-Wheeler, The Boy With the U.S. Miners
“ There aren't any door-boys in a modern mine. Most of the States in this country have passed laws requiring that all doors through which coal cars pass must be operated automatically. The United States Bureau of Mines keeps a sharp lookout, too. There aren't any donkeys, either, not in up-to-date mines; endless-chain conveyors take the coal from the face where the miner has dug it clear to the mouth of the shaft, and load it into the buckets by a self-tipping device. As for small boys in a mine, as you said yourself, there aren't any, not in the United States, anyhow. ”
