I had to skip around a bit, and jump up and crack my heels a few times—I couldn’t help it; but about the third crack I noticed a sound that I knowed mighty well, and held my breath and listened and waited; and sure enough, when the next flash busted out over the water, here they come!—and just a-laying to their oars and making their skiff hum! It was the king and the duke.
