This sandy desert is good enough for us, and we're not disturbed here," declared the Tottenhot.
So they left the man snuggling down to sleep in his dusky dwelling, and went out into the sunshine, taking the path that led toward the rocky places.

They soon found it hard climbing, for the rocks were uneven and full of sharp points and edges, and now there was no path at all.
Clambering here and there among the boulders they kept steadily on, gradually rising higher and higher until finally they came to a great rift in a part of the mountain, where the rock seemed to have split in two and left high walls on either side.
"S'pose we go this way," suggested Dorothy; "it's much easier walking than to climb over the hills." "How about that sign ?" asked Ojo.
"What sign ?" she inquired.
The Munchkin boy pointed to some words painted on the wall of rock beside them, which Dorothy had not noticed.

The words read: "LOOK OUT FOR YOOP." The girl eyed this sign a moment and turned to the Scarecrow, asking: "Who is Yoop; or what is Yoop ?" The straw man shook his head.

Then looked at Toto and the dog said "Woof!" "Only way to find out is to go on," said Scraps.
This being quite true, they went on.

As they proceeded, the walls of rock on either side grew higher and higher.
