All heads were bent over the golden peach pit. The Wizard turned it over several times and then took out his pocket knife and pried the pit open.

With a cry of delight, Dorothy rushed forward and embraced her. Scraps turned gleeful flipflops all around the room. Button-Bright gave a low whistle of astonishment. The Frogman took off his tall hat and bowed low before the beautiful girl who had been freed from her enchantment in so startling a manner. For a time, no sound was heard beyond the low murmur of delight that came from the amazed group, but presently the growl of the big Lavender Bear grew louder, and he said in a tone of triumph, "He never makes a mistake!"
