Betsy and Trot, when they heard of the rescue expedition, begged the Wizard to permit them to join it and he consented. The Glass Cat, overhearing the conversation, wanted to go also and to this the Wizard made no objection.
 
This Glass Cat was one of the real curiosities of Oz. It had been made and brought to life by a clever magician named Dr. Pipt, who was not now permitted to work magic and was an ordinary citizen of the Emerald City. The cat was of transparent glass, through which one could plainly see its ruby heart beating and its pink brains whirling around in the top of the head.
 
The Glass Cat's eyes were emeralds; its fluffy tail was of spun glass and very beautiful. The ruby heart, while pretty to look at, was hard and cold and the Glass Cat's disposition was not pleasant at all times. It scorned to catch mice, did not eat, and was extremely lazy. If you complimented the remarkable cat on her beauty, she would be very friendly, for she loved admiration above everything. The pink brains were always working and their owner was indeed more intelligent than most common cats.
 
Three other additions to the rescue party were made the next morning, just as they were setting out upon their journey. The first was a little boy called Button Bright, because he had no other name that anyone could remember. He was a fine, manly little fellow, well mannered and good humored, who had only one bad fault. He was continually getting lost. To be sure, Button Bright got found as often as he got lost, but when he was missing his friends could not help being anxious about him.
 
"Some day," predicted the Patchwork Girl, "he won't be found, and that will be the last of him." But that didn't worry Button Bright, who was so careless that he did not seem to be able to break the habit of getting lost.
 
The second addition to the party was a Munchkin boy of about Button Bright's age, named Ojo. He was often called "Ojo the Lucky," because good fortune followed him wherever he went. He and Button Bright were close friends, although of such different natures, and Trot and Betsy were fond of both.
 
The third and last to join the expedition was an enormous lion, one of Ozma's regular guardians and the most important and intelligent beast in all Oz. He called himself the Cowardly Lion, saying that every little danger scared him so badly that his heart thumped against his ribs, but all who knew him knew that the Cowardly Lion's fears were coupled with bravery and that however much he might be frightened he summoned courage to meet every danger he encountered. Often he had saved Dorothy and Ozma in times of peril, but afterward he moaned and trembled and wept because he had been so scared.
 
"If Ozma needs help, I'm going to help her," said the great beast. "Also, I suspect the rest of you may need me on the journey—especially Trot and Betsy—for you may pass through a dangerous part of the country. I know that wild Gillikin country pretty well. Its forests harbor many ferocious beasts."
 
They were glad the Cowardly Lion was to join them, and in good spirits the entire party formed a procession and marched out of the Emerald City amid the shouts of the people, who wished them success and a safe return with their beloved Ruler.
 
They followed a different route from that taken by Ozma and Dorothy, for they went through the Winkie Country and up north toward Oogaboo. But before they got there they swerved to the left and entered the Great Gillikin Forest, the nearest thing to a wilderness in all Oz. Even the Cowardly Lion had to admit that certain parts of this forest were unknown to him, although he had often wandered among the trees, and the Scarecrow and Tin Woodman, who were great travelers, never had been there at all.
 
The forest was only reached after a tedious tramp, for some of the Rescue Expedition were quite awkward on their feet. The Patchwork Girl was as light as a feather and very spry; the Tin Woodman covered the ground as easily as Uncle Henry and the Wizard; but Tik-Tok moved slowly and the slightest obstruction in the road would halt him until the others cleared it away. Then, too, Tik-Tok's machinery kept running down, so Betsy and Trot took turns in winding it up.
 
The Scarecrow was more clumsy but less bother, for although he often stumbled and fell he could scramble up again and a little patting of his straw-stuffed body would put him in good shape again.
 
Another awkward one was Jack Pumpkinhead, for walking would jar his head around on his neck and then he would be likely to go in the wrong direction. But the Frogman took Jack's arm and then he followed the path more easily.
 
Cap'n Bill's wooden leg didn't prevent him from keeping up with the others and the old sailor could walk as far as any of them.
 
When they entered the forest the Cowardly Lion took the lead. There was no path here for men, but many beasts had made paths of their own which only the eyes of the Lion, practiced in woodcraft, could discern. So he stalked ahead and wound his way in and out, the others following in single file, Glinda being next to the Lion.
 
There are dangers in the forest, of course, but as the huge Lion headed the party he kept the wild denizens of the wilderness from bothering the travelers. Once, to be sure, an enormous leopard sprang upon the Glass Cat and caught her in his powerful jaws, but he broke several of his teeth and with howls of pain and dismay dropped his prey and vanished among the trees.
 
"Are you hurt?" Trot anxiously inquired of the Glass Cat.
 
"How silly!" exclaimed the creature in an irritated tone of voice; "nothing can hurt glass, and I'm too solid to break easily. But I'm annoyed at that leopard's impudence. He has no respect for beauty or intellig............
