"We're Uns, we are, and nobody but Uns are allowed on this skyle. We'll have to take you along to the palace and his royal Skyness will decide what's to be done with you." "Another king," groaned the clown. "Isn't it time to run?" asked Bob, tugging at Notta's pantaloon, for the Uns were drawing closer this time, paying no attention to the roars of the Cowardly Lion. "No use running, Bob. We might fall off. Perhaps this King is a better fellow than his subjects. "Take us to your King!" cried the clown, settling his cap determinedly. Hopping and muttering, the Uns formed two crooked lines, and with the three travelers in the center marched away to the palace. There were many tall trees on the skyle of Un and, more remarkable still, every tree had a rough boxlike structure built in its branches, like enormous bird houses. They were reached by rough ladders and the Uns seemed to be as much at home on the branches as on the ground. Some of the women standing on lower branches were hanging clothes on upper ones as calmly as ordinary folk string the washing up in the yard. But, as Notta whispered to Bob, what could one expect of Featherheads? The skyle itself was rocky and barren and there seemed to be no farms, buildings nor industries of any kind. "What do you do here for a living?" asked Notta, turning to the Un beside him. "Fish, mostly," said the Un. "What for?" asked the Cowardly Lion, treading on Notta's heels in his eagerness to hear. "Birds," sniffed the Un, looking over his shoulder scornfully. "What did you think we'd fish for?" "Oh, but you couldn't fish for birds," objected Bob Up, stopping short, while Notta burst into a loud roar of laughter. The Un glared at all three. "The air's full of 'em," he announced sharply, and then, as the clown continued to laugh immoderately, his feathers began to ruffle with rage. "You're idiots!" he screamed, thrusting his sharp beak almost in Notta's face. "Idiots!" echoed all the other Uns immediately. Several trod on the clown's toes and, seeing that Bob was rather pale, Notta hastily changed the subject. Not long after that they came to the palace. To Bob it looked like a huge barn stuck between four trees. It was about ten feet from the ground and from the top of each tree fluttered a bright yellow flag bearing the word, UN. The Cowardly Lion trembled a good deal as they went up the rickety green ladder, but with a little help from Notta he managed it, and next instant they were in the presence of the King. "Two creatures and a beast, your Skyness!" announced the leader of the delegation. Then stepping close to Notta he shouted at the top of his voice, "His Majesty, I-wish-I-was, King of Un!" Notta's cap fell off and he clapped his hand to his ear. The Cowardly Lion made a little spring at the Un and had the pleasure of seeing the King's feathers rise erect upon his head and wave to and fro.
