" The driver and conductor on top were still, too, or only spoke at long intervals, in low tones, as is the way of men in the midst of invisible dangers. We listened to rain-drops pattering on the roof; and the grinding of the wheels through the muddy gravel; and the low wailing of the wind; and all the time we had that absurd sense upon us, inseparable from travel at night in a close-curtained vehicle, the sense of remaining perfectly still in one place, notwithstanding the jolting and swaying of the vehicle, the trampling of the horses, and the grinding of the wheels. "
