The country wasn't so pretty now. Before the travelers appeared a rocky plain covered with hills on which grew nothing green. They were nearing some low mountains, too, and the road, which before had been smooth and pleasant to walk upon, grew rough and uneven.  
Button-Bright's little feet stumbled more than once, and Polychrome ceased her dancing because the walking was now so difficult that she had no trouble to keep warm.
 
It had become afternoon, yet there wasn't a thing for their luncheon except two apples which the shaggy man had taken from the breakfast table. He divided these into four pieces and gave a portion to each of his companions. Dorothy and Button-Bright were glad to get theirs; but Polly was satisfied with a small bite, and Toto did not like apples.
 
"Do you know," asked the Rainbow's Daughter, "if this is the right road to the Emerald City?"
 
"No, I don't," replied Dorothy, "but it's the only road in this part of the country, so we may as well go to the end of it."
 
"It looks now as if it might end pretty soon," remarked the shaggy man; "and what shall we do if it does?"
 
"Don't know," said Button-Bright.
 
"If I had my Magic Belt," replied Dorothy, thoughtfully, "it could do us a lot of good just now."
 
"What is your Magic Belt?" asked Polychrome.
 
"It's a thing I captured from the Nome King one day, and it can do 'most any wonderful thing. But I left it with Ozma, you know; 'cause magic won't work in Kansas, but only in fairy countries."
 
"Is this a fairy country?" asked Button-Bright.
 
"I should think you'd know," said the little girl, gravely. "If it wasn't a fairy country you couldn't have a fox head and the shaggy man couldn't have a donkey head, and the Rainbow's Daughter would be invis'ble."
 
"What's that?" asked the boy.
 
"You don't seem to know anything, Button-Bright. Invis'ble is a thing you can't see."
 
"Then Toto's invis'ble," declared the boy, and Dorothy found he was right. Toto had disappeared from view, but they could hear him barking furiously among the heaps of grey rock ahead of them.
 
They moved forward a little faster to see what the dog was barking at, and found perched upon a point of rock by the roadside a curious creature. It had the form of a man, middle-sized and rather slender and graceful; but as it sat silent and motionless upon the peak they could see that its face was black as ink, and it wore a black cloth costume made like a union suit and fitting tight to its skin. Its hands were black, too, and its toes curled down, like a bird's. The creature was black all over except its hair, which was fine, and yellow, banged in front across the black forehead and cut close at the sides. The eyes, which were fixed steadily upon the barking dog, were small and sparkling and looked like the eyes of a weasel.
 
"What in the world do you s'pose that is?" asked Dorothy in a hushed voice, as the little group of travelers stood watching the strange creature.
 
"Don't know," said Button-Bright.
 
The thing gave a jump and turned half around, sitting in the same place but with the other side of its body facing them. Instead of being black, it was now pure white, with a face like that of a clown in a circus and hair of a brilliant purple. The creature could bend either way, and its white toes now curled the same way the black ones on the other side had done.
 
"It has a face both front and back," whispered Dorothy, wonderingly; "only there's no back at all, but two fronts."
 
Having made the turn, the being sat motionless as before, while Toto barked louder at the white man than he had done at the black one.
 
"Once," said the shaggy man, "I had a jumping jack like that, with two faces."
 
"Was it alive?" asked Button-Bright.
 
"No," replied the shaggy man; "it worked on strings and was made of wood."
 
"Wonder if this works with st............
