It looked like a real house in front and in back, but there wasn't any in-between. It was like one of those false-front saloons on a movie lot, but thinner. I thought of my wife, who had gone into the kitchen and, for all I knew, was as thin as the house, and I went charging in the back door, yelling. "Are you all right?" "Of course I'm all right," she said. "What's the matter with you?" I grabbed her and she was all there, thank heavens. She giggled and called me an old fool, but I dragged her outside and showed her what had happened to our house.

He was relieved to learn that the damage had been confined to himself and the house, so far as we knew. Like the house, Jack had insides, but we don't know where they are. We poured tea down him, and he can eat, after a fashion, but there never is a sign of a lump anywhere. That night, we pinned him to the bed with clothespins so he wouldn't blow off the bed. Next morning, we rigged a line and pinned him to it so he could sit up. "I know what to do," he said, "but I would
