Somewhere, far below the horizon, there is a City; some day I shall sail to find that sun-bright harbour; by what star I shall steer my vessel, or where that seaport lies, I know not; but somehow, through calms and storms and all the vague sea-noises I shall voyage, until at last some mountain peak will rise to tell me I am near my destination; or I shall see, some day at dusk, a lighthouse twinkling at its port.
