He landed in a snowbank. When he staggered to his feet, the cabin had vanished. All was white, swirling white, around him. Heading into the wind that had knocked him away, he eventually found the cabin. Climbing onto the roof a second time, he managed to fix the chimney pot, only to be hit by another gust of wind that sent him flying into the snow. "
