All the world rubs elbows in Washington. Outwardly it is merely a city of evasion, of conventionalities, sated with the commonplace pleasures of life, listless, blas even, and always exquisitely, albeit frigidly, courteous; but beneath the still, suave surface strange currents play at cross purposes, intrigue is endless, and the merciless war of diplomacy goes on unceasingly. Occasionally, only occasionally, a bubble comes to the surface, and when it bursts the echo goes crashing around the earth. Sometimes a dynasty is shaken, a nation trembles, a ministry topples over; but the ripple moves and all is placid again. No man may know all that happens there, for then he would be diplomatic master of the world.
