There is nothing dramatic in the success of a diplomatist. His victories are made up of a series of microscopic advantages: of a judicious suggestion here, or an opportune civility there: of a wise concession at one moment, and a farsighted persistence at another; of sleepless tact, immovable calmness, and patience that no folly, no provocation, no blunders can shake.
