I don't know what a breaker boy is; but his occupation seems to be standing by a coal dump with a wan look and a dinner-pail to have his picture taken for magazine articles.

And I've been worried for a long time about the coal dust that comes off the coal-piles in the winter. They dump it off the trucks near my apartment.

Coal ash dump outside the Shentou number two power plant, Shuozhou, Shanxi province.
