"What is it?" asked Dorothy, eagerly.
"Hush!" said the Admiral, in an agitated whisper. "We think it's where Bob Scarlet changes himself"—and as he said this there was a tremendous flapping of wings, and down came Bob Scarlet through the branches and landed with a thump a little way from where they were standing. He was as big as a goose again, and his appearance was so extremely formidable that the Caravan, as one man, threw themselves flat on their faces in a perfect frenzy of terror, and Dorothy herself hid in the grass, with her heart beating like a little eight-day clock. But Bob Scarlet fortunately paid no more attention to any of them than if they had been so many flies, and, after strutting about for a moment with his usual important air, strolled away in the direction of the toy-shop.
"Now what do you make of that?" said the Admiral, lifting up his head. "He went in at a little door not five minutes ago, and he wasn't any bigger than an every-day bird."
"I'm sure I don't know what to make of it," said Dorothy. "But where is the door?" she added, running around the tower and looking at it on all sides.
"It went up after him," said the Admiral, "like a corkscrew."
"And it's coming down again, like a gimlet!" shouted the Highlander; and, as they all looked up, sure enough there was the little door slowly coming down, around and around, as if it were descending an invisible staircase on the outside of the tower. They all watched this performance with much interest, and as the door touched the ground it opened, and, to Dorothy's amazement, out came the little field-mouse.
"What is it?" cried Dorothy, as they all crowded around the little creature. "Do tell us what it all means."
"It's a Sizing Tower," said the Mouse, its little voice trembling with agitation. "You get big at the top, and little at the bottom. I wouldn't go up there again—not for a bushel of nuts."
"Were you pretty big?" inquired Sir Walter.
"Monstrous!" said the Mouse, with a little shudder; "I was as big as a squirrel; and while I was up there, Bob Scarlet flew up and came down with the door, and there I was."
