"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.

"If we're spilled in this sand, in the middle of the desert," Dorothy thought to herself, "we'll be nothing but dust in a few minutes, and that will be the end of us."

But they were not spilled, and by-and-bye 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 rocks."

He heard her, and tried to pull down the sail; but the wind would not let go of the broad canvas and the ropes had become tangled.

Nearer and nearer they drew to the great rocks, and the shaggy man was in despair because he could do nothing to stop the wild rush of the sand-boat.
