"Oh, that's too bad!" cried Dorothy; "I wanted to thank Johnny Dooit for all his kindness to us."  
"He hasn't time to listen to thanks," replied the shaggy man; "but I'm sure he knows we are grateful. I suppose he is already at work in some other part of the world."
 
They now looked more carefully at the sand-boat, and saw that the bottom was modeled with two sharp runners which would glide through the sand. The front of the sand-boat was pointed like the bow of a ship, and there was a rudder at the stern to steer by.
 
It had been built just at the edge of the desert, so that all its length lay upon the gray sand except the after part, which still rested on the strip of grass.
 
"Get in, my dears," said the shaggy man; "I'm sure I can manage this boat as well as any sailor. All you need do is sit still in your places."
 
Dorothy got in, Toto in her arms, and sat on the bottom of the boat just in front of the mast. Button-Bright sat in front of Dorothy, while Polly leaned over the bow. The shaggy man knelt behind the mast. When all were ready he raised the sail half-way. The wind caught it. At once the sand-boat started forward—slowly at first, then with added speed. The shaggy man pulled the sail way up, and they flew so fast over the Deadly Desert that every one held fast to the sides of the boat and scarcely dared to breathe.
 
The sand lay in billows, and was in places very uneven, so that the boat rocked dangerously from side to side; but it never quite tipped over, and the speed was so great that the shaggy man himself became frightened and began to wonder how he could make the ship go slower.

But they were not spilled, and by-and-by Polychrome, who was clinging to the bow and looking straight ahead, saw a dark line before them and wondered what it was. It grew plainer every second, until she discovered it to be a row of jagged rocks at the end of the desert, while high above these rocks she could see a tableland of green grass and beautiful trees.
 
"Look out!" she screamed to the shaggy man. "Go slowly, or we shall smash into the r............
