Up spurted a perfect fountain of fire coming down over Dorothy and Pigasus in a shower of red hot sparks. But the sparks fell harmlessly as raindrops on the winged pig and the little girl, and after a great hiss and sputter went out, leaving the laboratory in darkness again. Scarcely had they recovered from this shock before a second blow was struck, and this time a hundred huge, hideous, black snakes came writhing out of the crystal, their green glittering eyes lighting up the room with a terrifying sulphurous light. The great twisting mass grew more and more menacing, sending out its long curving bodies like arms to encircle them. This, thought Dorothy, burying her head in Pigasus' wing, was black magic at its worst. Now she could feel the clammy coils all around her and waited breathlessly to be crushed and broken. But the cold, heavy bodies seemed powerless and without weight and presently they, too, slipped away and vanished. A shower of silver arrows followed the snakes and a cloud of choking green smoke, the arrows. But each blow on the crystal only seemed to prove further the potency of the kiss set on Dorothy's forehead so long ago by the Good Witch of the North. And because she clung so tightly to Pigasus, he, too, came unharmed through the hair-raising ordeal. As they both, almost afraid to breathe, waited for the next blow on the dark crystal, a long, tremulous sigh came mournfully through the darkness. "It is no use," murmured a discouraged voice, "my black magic is of no avail. Come, then, destroy me if you must, but do it quickly, and I pray you will spare my people who have never harmed or hurt a living soul in Oz." With a little thrill, Dorothy recognized the voice of the Black Queen, and as the dark lantern again shed its twinkling rays over the circular apartment, Gloma rose and came calmly and rapidly toward them. Dorothy and Pigasus, who had just had their own bravery so severely tested, could not but admire the spirit and bravery of the Witch of the Black Forest. Even though she was sure she faced certain destruction, she walked proudly erect, her head flung back, her great mass of dusky hair billowing behind her. "Stop!" cried Dorothy, on whom the Queen's dark beauty had made a deep and lasting impression. "Why should we wish to destroy you? We came through the Yellow Wood and from there into the Black Forest, but we only wished to go through as quickly as possible. We are in trouble ourselves. Did you know that Ozma of Oz, the Wizard of Oz, the four rulers of Oz, and many others have vanished? There is a false Emperor on the throne in the Emerald City and under the magic of his enchantment all the people have forgotten Ozma ever was their Queen. Pigasus and I, escaping this enchantment, are trying to find Ozma and someone to help us restore her to power." Dorothy spoke with such earnestness and feeling, Gloma could not help believing her.
