Chapter Twelve. The Giant Porcupine

Next morning they started out bright and early to follow the road of yellow bricks toward the Emerald City. The little Munchkin boy was beginning to feel tired from the long walk, and he had a great many things to think of and consider besides the events of the journey. At the wonderful Emerald City, which he would presently reach, were so many strange and curious people that he was half afraid of meeting them and wondered if they would prove friendly and kind. Above all else, he could not drive from his mind the important errand on which he had come, and he was determined to devote every energy to finding the things that were necessary to prepare the magic recipe. He believed that until dear Unc Nunkie was restored to life he could feel no joy in anything, and often he wished that Unc could be with him, to see all the astonishing things Ojo was seeing. But alas Unc Nunkie was now a marble statue in the house of the Crooked Magician and Ojo must not falter in his efforts to save him.

The country through which they were passing was still rocky and deserted, with here and there a bush or a tree to break the dreary landscape. Ojo noticed one tree, especially, because it had such long, silky leaves and was so beautiful in shape. As he approached it he studied the tree earnestly, wondering if any fruit grew on it or if it bore pretty flowers.

Suddenly he became aware that he had been looking at that tree a long time--at least for five minutes--and it had remained in the same position, although the boy had continued to walk steadily on. So he stopped short. and when he stopped, the tree and all the landscape, as well as his companions, moved on before him and left him far behind.

Ojo uttered such a cry of astonishment that it aroused the Shaggy Man, who also halted. The others then stopped, too, and walked back to the boy.

"What's wrong?" asked the Shaggy Man.

"Why, we're not moving forward a bit, no matter how fast we walk," declared Ojo. "Now that we have stopped, we are moving backward! Can't you see? Just notice that rock."

Scraps looked down at her feet and said: "The yellow bricks are not moving."

"But the whole road is," answered Ojo.

"True; quite true," agreed the Shaggy Man. "I know all about the tricks of this road, but I have been thinking of something else and didn't realize where we were."

"It will carry us back to where we started from," predicted Ojo, beginning to be nervous.

"No," replied the Shaggy Man; "it won't do that, for I know a trick to beat this tricky road. I've traveled this way before, you know. Turn around, all of you, and walk backward."

"What good will that do?" asked the cat.

"You'll find out, if you obey me," said the Shaggy Man.

So they all turned their backs
