Famous quotes containing the word hour:
“You have but little more to do than throw up your cap for entertainment these American days.... Farmers’ sons will stare by the hour to see a juggler draw ribbons from his throat, though he tells them it is all deception. Surely, men love darkness rather than light.”
—Henry David Thoreau (1817–1862)
