"Couldn't we go around it?" asked Woot.
"Of course, for the wall is a circle," explained the rabbit. "In the center of the circle stands the house, so you may walk around the Wall of Solid Air, but you can't get to the house."
"Who put the air wall around the house?" was the Scarecrow's question.
"Nimmie Amee did that."
"Nimmie Amee!" they all exclaimed in surprise.
"Yes," answered the rabbit. "She used to live with an old Witch, who was suddenly destroyed, and when Nimmie Amee ran away from the Witch's house, she took with her just one magic formula—pure sorcery it was—which enabled her to build this air wall around her house—the house yonder. It was quite a clever idea, I think, for it doesn't mar the beauty of the landscape, solid air being invisible, and yet it keeps all strangers away from the house."
"Does Nimmie Amee live there now?" asked the Tin Woodman anxiously.
"Yes, indeed," said the rabbit.
"And does she weep and wail from morning till night?" continued the Emperor.
"No; she seems quite happy," asserted the rabbit.
