"It's an old rattling, banging trap of a wagon, hauled by an old, bony horse, that I drive around collecting rags in," explained Santa Claus, which, though they knew he wasn't, the children always, afterward, called him.  "I'm a sort of a junker," he went on, "and my wagon is a rattle-bang.  But my horse is strong, if he is bony, and my wagon has a cover on, to keep out the snow.  So, if you would like to ride with me, I'll take you home."
