"We cannot be far from the road of yellow brick, now," remarked the Scarecrow (稻草人), as he stood beside the girl, "for we have come nearly as far as the river carried us away. "
The Tin Woodman(铁皮人) was about to reply when he heard a low growl, and turning his head (which worked beautifully on hinges) he saw a strange beast come bounding over the grass toward them. It was, indeed, a great yellow Wildcat(野猫), and the Woodman thought it must be chasing something, for its ears were lying close to its head and its mouth was wide open, showing two rows of ugly teeth, while its red eyes glowed like balls of fire. As it came nearer the Tin Woodman saw that running before the beast was a little gray field mouse(田鼠), and although he had no heart he knew it was wrong for the Wildcat to try to kill such a pretty, harmless creature. So the Woodman raised his axe(斧头), and as the Wildcat ran by he gave it a quick blow that cut the beast's head clean off from its body, and it rolled over at his feet in two pieces.
The field mouse, now that it was freed from its enemy, stopped short; and coming slowly up to the Woodman it said, in a strange little voice: "Oh, thank you! Thank you ever so much for saving my life. "
"Don't speak of it, I beg of you," replied the Woodman. "I have no heart, you know, so I am careful to help all those who may need a friend, even if it happens to be only a mouse."
"Only a mouse!" cried the little animal angrily. "Why, I am a Queen—the Queen of all the Field Mice!" "Oh, indeed," said the Woodman, making a bow. "Therefore you have done a great deed, as well as a brave one, in saving my life," added the Queen.
At that moment several mice were seen running up as fast as their little legs could carry them, and when they saw their Queen they exclaimed: "Oh, your Majesty, we thought you would be killed! How did you manage to escape the great Wildcat?" They all bowed so low to the little Queen that they almost stood upon their heads.
"This funny tin man," she answered, "killed the Wildcat and saved my life. So hereafter you must all serve him, and obey his slightest wish."
