"We'll have to think of something else," grumbled the pig, as Dorothy again sat down on her stool.

"Are you thinking?" he demanded sharply, as the little girl stared absently at the tips of her boots.

"No," confessed Dorothy frankly, "I was just wondering why Gloma calls this a dark room. She must know since General Blotz ducked us under the Black River we can see in here as well as in the forest."

"I wouldn't be too sure of that," muttered the pig, coming over and crowding as close to Dorothy as he could. It almost seemed as if someone had heard him, for scarcely were the words out of his mouth before the dark lantern over their heads sputtered ominously and went out, leaving them in a perfectly pitch black total darkness.

"I—I—I felt something like this would happen," faltered Pigasus, throwing his left wing protectingly around Dorothy. "Listen! Someone is coming."

A light sure footstep sounded in the passage—came closer, then a sudden puff of air told them that someone had opened the door.

"Remember, Piggins dear, no matter what happens, we must be brave," whispered Dorothy, trembling a little in spite of herself.

"It's hard to be brave in the dark, but I'll do my best. Here, lean on me." And though the happenings of the next ten minutes were enough to try the courage of a dozen lions, Pigasus kept his word and never uttered a sound. As the two prisoners clung desperately together the crystal on the center table received a sudden shattering blow.

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.

"Then—then you did not come here to destroy me at all?" she exclaimed with an unhappy and embarrassed glance at her two prisoners. "Forgive me for using my magic powers, I only wanted to save myself and my foresters from obliteration."

"Oh, that's all right." Dorothy dismissed with a careless shrug the danger and discomfort of the last hour. "You thought we were going to destroy you, so, of course, you tried to destroy us first. That was fair enough and I don't blame you, but now that we understand each other better, perhaps you will help us? Do you, yourself, remember Ozma, and is your magic powerful enough to tell us where she is?"

Seating herself in a chair near Dorothy's footstool, Gloma stared thoughtfully at the velvet carpet.

"I know or remember nothing of the present history of Oz," she told them after a short silence. "At the time the Wizard of Oz ruled Oz I ruled by royal right and inheritance the entire southern part of the Winkie Empire. Although the Wicked Witch of the East claimed dominion over the whole country, she only succeeded in bringing the central and northern parts under her control. We in the South were free, but when word came that a mortal girl had destroyed both the Witch of the East and the Witch of the West, I, being a witch, naturally supposed I would be the next one to suffer destruction. So, calling together the strongest and most faithful of my subjects, I begged them to retire with me to a safe and hidden spot where we could live in safety and tranquillity far from the wars, dangers, and changing fortunes of the times. Many of my Southern Winkies cast their lot with the new order, marching off to the North, but many came with me, and retiring to this hidden forest, we cut ourselves off from all intercourse with the other Kingdoms of Oz, living the free and happy life of foresters and enjoying all the beauty and benefits of outdoor sport and activity. Of the rulers in Oz since the Wizard, I know nothing whatever."

"And were you always black?" inquired Pigasus, peering inquisitively up into Gloma's face, and wondering whether the two small black wings on each side of her forehead were as useful as his own.

"No," admitted the Queen, smiling graciously down at her plump questioner. "That was part of our disappearing plan, in a dark forest we were so much less likely to be found or discovered, so with my knowledge of the black arts I turned myself and my subjects as black as you now see us."

"What a shame! What a pity!" Dorothy jumped up and perched cozily on the arm of the Black Queen's chair. "If you had just come to the Emerald City, we could have been friends all this while."

"Why not begin now?" smiled the Queen, putting her arm affectionately round Dorothy's waist. "And you must not be sorry for us, for here we have been perfectly happy and content and I have grown so fond of my black forest and castle I would not change their lovely sable for all the other colors in the rainbow. But tell me quickly again all that has happened in Oz and perhaps I can make amends for the shabby treatment you have received at our hands."

Contritely the Black Queen leaned down to pat Pigasus, and as Dorothy sketched in most of the important happenings in Oz since the reign of the Wizard, the little pig pressed closely against her side. With many interested nods and exclamations Gloma listened, and when Dorothy described the great festival that had been planned to celebrate the discovery of Oz by mortals, how Ozma and all her most important visitors and advisers had vanished at the banquet, and a false Emperor taken possession of the palace, the Queen rose and walked solemnly over to the black crystal. But after a long look into its inky depths, Gloma turned sadly away.
