"It will do that," declared Johnny Dooit. "All you need worry about is tipping over. Did you ever sail a ship?"
"I've seen one sailed," said the shaggy man.
"Good. Sail this boat the way you've seen a ship sailed, and you'll be across the sands before you know it."
With this he slammed down the lid of the chest, and the noise made them all wink. While they were winking the workman disappeared, tools and all.
"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 modelled 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 grey sand except the after part, which still rested on the strip of grass.
