To their disappointment there was within this mountain no regular flight of steps by means of which they could mount to the earth’s surface. A sort of inclined tunnel led upward for a way, and they found the floor of it both rough and steep. Then a sudden turn brought them to a narrow gallery where the buggy could not pass. This delayed and bothered them for a while, because they did not wish to leave the buggy behind them. It carried their baggage and was useful to ride in wherever there were good roads, and since it had accompanied them so far in their travels they felt it their duty to preserve it. So Zeb and the Wizard set to work and took off the wheels and the top, and then they put the buggy edgewise, so it would take up the smallest space. In this position they managed, with the aid of the patient cab-horse, to drag the vehicle through the narrow part of the passage. It was not a great distance, fortunately, and when the path grew broader they put the buggy together again and proceeded more comfortably. But the road was nothing more than a series of rifts or cracks in the mountain, and it went zigzag in every direction, slanting first up and then down until they were puzzled as to whether they were any nearer to the top of the earth than when they had started, hours before.
