Even now the raindrops were beginning to fall, but it was quite dry inside the tunnel and by the time they had reached the other end, outside the circular Wall of Solid Air, the storm was at its height and the rain was coming down in torrents.

"Let us wait here," proposed Polychrome, peering out of the hole and then quickly retreating. "The Rainbow won't appear until after the storm and I can make you big again in a jiffy, before I join my sisters on our bow."

"That's a good plan," said the Scarecrow approvingly. "It will save me from getting soaked and soggy."

"It will save me from rusting," said the Tin Soldier.

"It will enable me to remain highly polished," said the Tin Woodman.

"Oh, as for that, I myself prefer not to get my pretty clothes wet," laughed the Rainbow's daughter.

"But while we wait I will bid you all adieu. I must also thank you for saving me from that dreadful Giantess, Mrs. Yoop. You have been good and patient comrades and I have enjoyed our adventures together, but I am never so happy as when on my dear Rainbow."
