" the cradle swayed and swung luxuriously, the pattering of the horses’ hoofs, the cracking of the driver’s whip, and his “Hi-yi! g’lang!” were music; the spinning ground and the waltzing trees appeared to give us a mute hurrah as we went by, and then slack up and look after us with interest, or envy, or something; and as we lay and smoked the pipe of peace and compared all this luxury with the years of tiresome city life that had gone before it, we felt that there was only one complete and satisfying happiness in the world, and we had found it.
