“We shan’t mind it if it hasn’t tumbled in since we came, and shut us up.”
“I say, don’t!” cried Mike, with a look of horror. “That might be true, you know.”
“Yes; but pigs might fly,” cried Vince, laughing. “I say, what a chap you are to take fright! Puzzle a stone place like that to tumble in. A few bits might come off the roof, but even then we could crawl over them, for they must leave a hole where they come from. Ready?”
“Yes,” said Mike unwillingly, and they walked to the foot of the slide.
“I’ll go first,” cried Vince; and, seizing the rope, he held on by it, and, shortening his hold as he went, contrived to walk right up to the top, in spite of the great angle at which it stood.
“Try that way, Mike: it’s as easy as easy.”
The boy tried, and after a slip or two managed to reach the top pretty well. Here it was found that the candle had burned right out, but without injuring the socket; and a fresh piece having been set up, a light was soon obtained, and they started back, after deciding to leave the rope where it was, ready for their next visit, as they did not anticipate any difficulty about climbing back up the various step-like falls.
There was plenty to have detained them during their return journey, for the passage of the little underground river presented a wonderfully different aspect from the new point of view, and often seemed dimly mysterious by the feeble yellow light of the horn lanthorn; but there were no difficulties that a couple of active lads ready to help each other did not readily surmount; and they went on turning curves and loops and corners, mounting places that were once waterfalls, and steadily progressing, till Mike was horrified by one of his companion’s remarks.
It was just as they had paused breathless before beginning to climb one of the great step-like impediments.
“I say, Ladle,” he cried, “suppose the water was to come back all of a sudden, and begin rushing down here! What should we do?”
