" At that, the angel tore open his breast, and displaying all the qualities therein to the assembled poultry, took out his ability to alter his shape. He handed it to the fattest goose to hold for the duration of the match, and the goose at once transformed himself, becoming a gray salt goose, such as stream from pole to pole. But he did not fly off, and he kept the angel's ability safe. "
