P. T. Barnum,
The Humbugs of the World — Chapter XLVIII
(1866)
“ They set up a little mill to go by water or wind, which turns a cylinder. On this cylinder is written a prayer, and every time the barrel goes round once, it counts, they say, for one prayer. It may be imagined how piety intensifies in a freshet, or in a heavy gale of wind! And there is a ludicrous notion of economy, as well as a pitiable folly in the conception of profiting by such windy supplications, and of saving all one’s time and thoughts for business, while the prayers rattle out by the hundred at home. ”
