Inside the archway were several doors, leading to different rooms built into the mountain, and Zeb and the Wizard lifted these wooden doors from their hinges and tossed them all on the flames.

"That will prove a barrier for some time to come," said the little man, smiling pleasantly all over his wrinkled face at the success of their stratagem. "Perhaps the flames will set fire to all that miserable wooden country, and if it does the loss will be very small and the Gargoyles never will be missed. But come, my children; let us explore the mountain and discover which way we must go in order to escape from this cavern, which is getting to be almost as hot as a bake-oven."

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 zig-zag 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.
