"Wait a minute!" cried Dorothy. "I've got a letter from Ozma."

"From the Ruler of Oz?" asked the rabbit, doubtingly.

"Of course. Ozma's my best friend, you know; and I'm a Princess myself," she announced, earnestly.

"Hum—ha! Let me see your letter," returned the rabbit, as if he still doubted her.

So she hunted in her pocket and found the letter Ozma had given her. Then she handed it through the bars to the rabbit, who took it in his paws and opened it. He read it aloud in a pompous voice, as if to let Dorothy and Billina see that he was educated and could read writing. The letter was as follows:

"It will please me to have my subjects greet Princess Dorothy, the bearer of this royal missive, with the same courtesy and consideration they would extend to me."

"Ha—hum! It is signed 'Ozma of Oz,'" continued the rabbit, "and is sealed with the Great Seal of the Emerald City. Well, well, well! How strange! How remarkable!"

"What are you going to do about it?" inquired Dorothy, impatiently.

"We must obey the royal mandate," replied the rabbit. "We are subjects of Ozma of Oz, and we live in her country. Also we are under the protection of the great Sorceress Glinda the Good, who made us promise to respect Ozma's commands."
