"Pouf!" he sniffed, snapping his fingers scornfully. "Do you suppose a mere girl like this Ohsma of Ohs can frighten me? My Blowmen will soon attend to her and anyone else who stands in our way!"

"That," shouted Nick, raising his voice above the roar of the engine,—"remains to be seen!" As a matter of fact, the Oztober and the swarm of flying Warriors had been sighted almost as soon as they appeared above the green lands edging the capitol. Long before they reached the Emerald City itself, terrified messengers had brought word of the approaching airmen. Ozma being absent, Bettsy and Trot, the two little mortal girls who lived with Dorothy and the Supreme Ruler in the Emerald Palace, were in charge.

After one glance at the flying army, they had called all the celebrities, servants and courtiers together and bade them flee for their lives. Then Bettsy, Trot, and the Patchwork Girl, climbed into the Red Wagon. With the Saw Horse to pull them, they set off at a gallop to hide in the Blue Forests of the Munchkin Country till the invasion was over. Tik Tok, the Machine Man, carrying all of Ozma's loose jewels and valuables, marched rapidly after them. The Medicine Man rode the Hungry Tiger and the rest of the palace inmates ran helter-skelter down the yellow brick highway from the Capitol.

The inhabitants of the Emerald City itself, never having seen the Wizard's Ozoplanes and having no way of knowing that Nick Chopper was inside this one, were almost as afraid of the Oztober as of the Stratovanians. Pelting into their houses and shops, they bolted windows and doors and waited in terror-stricken silence for whatever was to come. Only the Guardian of the Gate stayed bravely at his post, waving his bunch of keys defiantly as the Ozoplane and the Airlanders swooped over the castle wall.

"Ho! No you don't!" cried Strut, as Nick, having brought the plane to a landing, started to run for the door. "You'll stay with me, as a hostage!" he rasped, gripping the Tin Woodman's arm. Furious but helpless in the iron grasp of the Stratovanian, Nick was forced to lead him into Ozma's beautiful castle.

Strut's warriors, after fluttering like curious birds from tree to tree and alighting in chattering groups on the wall, finally furled the wings of their staffs, formed ranks and marched, singing and shouting, up the steps after their jubilant leader.

In vain Nick watched for any signs of weakening among them. The Airmen seemed as comfortable and carefree in this lower altitude as they had been on their own airosphere. The Tin Woodman's only consolation was that he had brought back the Wizard's Ozoplane in as good condition as when it had started away so unexpectedly. It was also a great relief to him to find the castle deserted. Not a courtier, servant or celebrity was in sight—not even the Glass Cat or Dorothy's little kitten Eureka. Strut and his rude army stamped through the first floor from end to end without encountering a single soul.

"Very good," sniffed the Ruler of all the Stratovanians, shooting his eyes sharply to left and right, "so this powerful fairy Ohsma of Ohs has run off and left us her castle, and we win the war without blowing a blow! Ho, Ho! I shall spend my summers in this enchanting palace," he added, with a malicious wink at the Tin Woodman. "But now," his grasp on Nick's arm tightened. "Where are these famous, magic treasures and jewels you were boasting of—this belt and fan and all the other foolishments and fripperies?"

"In a safe in Ozma's own apartment," Nick told him, reluctantly. Now that Strut was in complete possession of the castle, little was to be gained by concealing the location of the treasures.
