“In private life he was good-natured, chearful, social; inelegant in his manners, loose in his morals. He had a coarse, strong wit, which he was too free of for a man in his station, as it is always inconsistent with dignity. He was very able as a minister, but without a certain *elevation* of mind necessary for great good, or great mischief.”

—Philip Dormer Stanhope, 4th Earl Chesterfield (1694–1773)

“Bees

Shaking the heavy dews from bloom and frond.

Boys

Bursting the *surface* of the ebony pond.”

—Wilfred Owen (1893–1918)
