"It may be," admitted the Scarecrow.

"But why," asked Glinda, "did he make three secret visits to old Mombi?"

"Ah! Why, indeed!" echoed the Woggle-Bug, impressively.

"We know that the Wizard taught the old woman many of his tricks of magic," continued Glinda; "and this he would not have done had she not assisted him in some way. So we may suspect with good reason that Mombi aided him to hide the girl Ozma, who was the real heir to the throne of the Emerald City, and a constant danger to the usurper. For, if the people knew that she lived, they would quickly make her their Queen and restore her to her rightful position."

"An able argument!" cried the Scarecrow. "I have no doubt that Mombi was mixed up in this wicked business. But how does that knowledge help us?"

"We must find Mombi," replied Glinda, "and force her to tell where the girl is hidden."

"Mombi is now with Queen Jinjur, in the Emerald, City" said Tip. "It was she who threw so many obstacles in our pathway, and made Jinjur threaten to destroy my friends and give me back into the old witch's power."

"Then," decided Glinda, "I will march with my army to the Emerald City, and take Mombi prisoner. After that we can, perhaps, force her to tell the truth about Ozma."

"She is a terrible old woman!" remarked Tip, with a shudder at the thought of Mombi's black kettle; "and obstinate, too."

"I am quite obstinate myself," returned the Sorceress, with a sweet smile. "so I do not fear Mombi in the least. Today I will make all necessary preparations, and we will march upon the Emerald City at daybreak tomorrow."

The Army of Glinda the Good looked very grand and imposing when it assembled at daybreak before the palace gates. The uniforms of the girl soldiers were pretty and of gay colors, and their silver-tipped spears were bright and glistening, the long shafts being inlaid with mother-of-pearl. All the officers wore sharp, gleaming swords, and shields edged with peacock-feathers; and it really seemed that no foe could by any possibility defeat such a brilliant army.

The Sorceress rode in a beautiful palanquin which was like the body of a coach, having doors andwindows with silken curtains; but instead of wheels, which a coach has, the palanquin rested upon two long, horizontal bars, which were borne upon the shoulders of twelve servants.

The Scarecrow and his comrades decided to ride in the Gump, in order to keep up with the swift march of the army; so, as soon as Glinda had started and her soldiers had marched away to the inspiring strains of music played by the royal band, our friends climbed into the sofas and followed. The Gump flew along slowly at a point directly over the palanquin in which rode the Sorceress.

"Be careful," said the Tin Woodman to the Scarecrow, who was leaning far over the side to look at the army below. "You might fall."

"It wouldn't matter," remarked the educated Woggle-Bug. "he can't get broke so long as he is stuffed with money."

"Didn't I ask you" began Tip, in a reproachful voice.

"You did!" said the Woggle-Bug, promptly. "And I beg your pardon. I will really try to restrain myself."

"You'd better," declared the boy. "That is, if you wish to travel in our company."

"Ah! I couldn't bear to part with you now," murmured the Insect, feelingly; so Tip let the subject drop.

The army moved steadily on, but night had fallen before they came to the walls of the Emerald City. By the dim light of the new moon, however, Glinda's forces silently surrounded the city and pitched their tents of scarlet silk upon the greensward. The tent of the Sorceress was larger than the others, and was composed of pure white silk, with scarlet banners flying above it. A tent was also pitched for the Scarecrow's party; and when these preparations had been made, with military precision and quickness, the army retired to rest.

Great was the amazement of Queen Jinjur next morning when her soldiers came running to inform her of the vast army surrounding them. She at once climbed to a high tower of the royal palace and saw banners waving in every direction and the great white tent of Glinda standing directly before the gates.

"We are surely lost!" cried Jinjur, in despair; "for how can our knitting-needles avail against the long spears and terrible swords of our foes?"

"The best thing we can do," said one of the girls, "is to surrender as quickly as possible, before we get hurt."

"Not so," returned Jinjur, more bravely. "The enemy is still outside the walls, so we must try to gain time by engaging them in parley. Go you with a flag of truce to Glinda and ask her why she has dared to invade my dominions, and what are her demands."

So the girl passed through the gates, bearing a white flag to show she was on a mission of peace, and came to Glinda's tent. "Tell your Queen," said the Sorceress to the girl, "that she must deliver up to me old Mombi, to be my prisoner. If this is done I will not molest her farther."

[Line-Art Drawing]

Now when this message was delivered to the Queen it filled her with dismay, for Mombi was her chief counsellor, and Jinjur was terribly afraid of the old hag. But she sent for Mombi, and told her what Glinda had said.

"I see trouble ahead for all of us," muttered the old witch, after glancing into a magic mirror she carried in her pocket. "But we may even yet escape by deceiving this sorceress, clever as she thinks herself."

"Don't you think it will be safer for me to deliver you into her hands?" asked Jinjur, nervously.

"If you do, it will cost you the throne of the Emerald City!" answered the witch, positively. "But if you will let me have my own way, I can save us both very easily."

"Then do as you please," replied Jinjur, "for it is so aristocratic to be a Queen that I do not wish to be obliged to return home again, to make beds and wash dishes for my mother."

So Mombi called Jellia Jamb to her, and performed a certain magical rite with which she was familiar. As a result of the enchantment Jellia took on the form and features of Mombi, while the old witch grew to resemble the girl so closely that it seemed impossible anyone could guess the deception.

"Now," said old Mombi to the Queen, "let your soldiers deliver up this girl to Glinda. She will think she has the real Mombi in her power, and so will return immediately to her own country in the South."

Therefore Jellia, hobbling along like an aged woman, was led from the city gates and taken before Glinda.

"Here is the person you demanded," said one of the guards, "and our Queen now begs you will go away, as you promised, and leave us in peace."

"That I will surely do," replied Glinda, much pleased; "if this is really the person she seems to be."

"It is certainly old Mombi," said the guard, who believed she was speaking the truth; and then Jinjur's soldiers returned within the city's gates.

The Sorceress quickly summoned the Scarecrow and his friends to her tent, and began to question the supposed Mombi about the lost girl Ozma. But Jellia knew nothing at all of this affair, and presently she grew so nervous under the questioning that she gave way and began to weep, to Glinda's great astonishment.
