"Nothing could make me forget what I know," remarked the Scarecrow, gazing into the fountain, "for I cannot drink the Water of Oblivion or water of any kind. And I am glad that this is so, for I consider my wisdom unexcelled."

"You are cer–tain–ly ve–ry wise," agreed Tiktok. "For my part, I can on–ly think by ma–chin–er–y, so I do not pre–tend to know as much as you do."

"My tin brains are very bright, but that is all I claim for them," said Nick Chopper, modestly. "Yet I do not aspire to being very wise, for I have noticed that the happiest people are those who do not let their brains oppress them."

"Mine never worry me," Jack Pumpkinhead acknowledged. "There are many seeds of thought in my head, but they do not sprout easily. I am glad that it is so, for if I occupied my days in thinking I should have no time for anything else."

In this cheery mood they passed the hours until the first golden streaks of dawn appeared in the sky. Then Ozma joined them, as fresh and lovely as ever and robed in one of her prettiest gowns.

"Our enemies have not yet arrived," said the Scarecrow, after greeting affectionately the sweet and girlish Ruler.

"They will soon be here," she said, "for I have just glanced at my Magic Picture, and have seen them coughing and choking with the dust in the tunnel."

"Oh, is there dust in the tunnel?" asked the Tin Woodman.

"Yes; Ozma placed it there by means of the Magic Belt," explained the Scarecrow, with one of his broad smiles.

Then Dorothy came to them, Uncle Henry and Aunt Em following close after her. The little girl's eyes were heavy because she had had a sleepless and anxious night. Toto walked by her side, but the little dog's spirits were very much subdued. Billina, who was always up by daybreak, was not long in joining the group by the fountain.

The Wizard and the Shaggy Man next arrived, and soon after appeared Omby Amby, dressed in his best uniform.

"There lies the tunnel," said Ozma, pointing to a part of the ground just before the Forbidden Fountain, "and in a few moments the dreadful invaders will break through the earth and swarm over the land. Let us all stand on the other side of the Fountain and watch to see what happens."

At once they followed her suggestion and moved around the fountain of the Water of Oblivion. There they stood silent and expectant until the earth beyond gave way with a sudden crash and up leaped the powerful form of the First and Foremost, followed by all his grim warriors.
