“I wonder how Jim is ever going to draw the buggy up so many stairs,” said Dorothy, gravely.

“No trouble at all,” declared the horse, with a contemptuous neigh. “Still, I don’t care to drag any passengers. You’ll all have to walk.”

“Suppose the stairs get steeper?” suggested Zeb, doubtfully.

“Then you’ll have to boost the buggy-wheels, that’s all,” answered Jim.

“We’ll try it, anyway,” said the Wizard. “It’s the only way to get out of the Valley of Voe.”

So they began to ascend the stairs, Dorothy and the Wizard first, Jim next, drawing the buggy, and then Zeb to watch that nothing happened to the harness.
