I have no doubt that the Romans planned the time-table of their days far better than we do. They rose before the sun at all seasons. Except in wartime we never see the dawn. Sometimes we see sunset. The message of sunset is sadness; the message of dawn is hope. The rest and the spell of sleep in the middle of the day refresh the human frame far more than a long night. We were not made by Nature to work, or even play, from eight o'clock in the morning till midnight. We throw a strain upon our system which is unfair and improvident. For every purpose of business or pleasure, mental or physical, we ought to break our days and our marches into two.
