“ One hour a day withdrawn from frivolous pursuits and profitably employed would enable any man of ordinary capacity to master a complete science. One hour a day would in ten years make an ignorant man a well-informed man…In an hour a day, a boy or girl could read twenty pages thoughtfully—over seven thousand pages, or eighteen large volumes in a year. An hour a day might make all the difference between bare existence and useful, happy living. An hour a day might make—nay, has made—an unknown man a famous one, a useless man a benefactor to his race. ”
