"Well, perhaps it is more serious than I imagined," admitted the fair Ruler; "but I haven't given the matter much thought. After dinner we will all meet together and talk it over."

So they went to their rooms and prepared for dinner, and Dorothy dressed herself in her prettiest gown and put on her coronet, for she thought that this might be the last time she would ever appear as a Princess of Oz.

The Scarecrow, the Tin Woodman and Jack Pumpkinhead all sat at the dinner table, although none of them was made so he could eat. Usually they served to enliven the meal with their merry talk, but to–night all seemed strangely silent and uneasy.

As soon as the dinner was finished Ozma led the company to her own private room in which hung the Magic Picture. When they had seated themselves the Scarecrow was the first to speak.

"Is the Nome King's tunnel finished, Ozma?" he asked.

"It was completed to–day," she replied. "They have built it right under my palace grounds, and it ends in front of the Forbidden Fountain. Nothing but a crust of earth remains to separate our enemies from us, and when they march here, they will easily break through this crust and rush upon us."

"Who will assist the Nome King?" inquired the Scarecrow.

"The Whimsies, the Growleywogs and the Phanfasms," she replied. "I watched to–day in my Magic Picture the messengers whom the Nome King sent to all these people to summon them to assemble in his great caverns."

"Let us see what they are doing now," suggested the Tin Woodman.

So Ozma wished to see the Nome King's cavern, and at once the landscape faded from the Magic Picture and was replaced by the scene then being enacted in the jeweled cavern of King Roquat.

A wild and startling scene it was which the Oz people beheld.

Before the Nome King stood the Chief of the Whimsies and the Grand Gallipoot of the Growleywogs, surrounded by their most skillful generals. Very fierce and powerful they looked, so that even the Nome King and General Guph, who stood beside his master, seemed a bit fearful in the presence of their allies.

Now a still more formidable creature entered the cavern. It was the First and Foremost of the Phanfasms and he proudly sat down in King Roquat's own throne and demanded the right to lead his forces through the tunnel in advance of all the others. The First and Foremost now appeared to all eyes in his hairy skin and the bear's head. What his real form was even Roquat did not know.

Through the arches leading into the vast series of caverns that lay beyond the throne room of King Roquat could be seen ranks upon ranks of the invaders—thousands of Phanfasms, Growleywogs and Whimsies standing in serried lines, while behind them were massed the thousands upon thousands of General Guph's own army of Nomes.
