"Let's look," proposed Trot, darting eagerly toward the back of the cavern. Hurriedly they circled one entire side without success. Tumbling straight from the top of the cave on the other side was a sparkling silver water-fall. "I wonder what's beyond that?" muttered the Scarecrow looking up at it thoughtfully. "Water doesn't hurt me, so I'll just take a look," said the stone man and before Trot or the Scarecrow could stop him Benny stepped right through the water-fall and disappeared. With a sharp cry of distress Trot rushed forward. "He's gone!" wailed the little girl dolefully. The Scarecrow looked almost as upset as Trot, for even in this short time he had grown fond of their strange stone comrade. As they discussed in anxious tones what they had better do, the dripping face of Benny looked out through the water-fall. "Come on!" he spluttered excitedly. "Run through, it leads into another cave!" Taking a deep breath and the Scarecrow's hand, Trot plunged into the water-fall. Benny seized them just in time, for the terrible rush of water took Trot's breath and the poor Scarecrow was limp and helpless, when they stepped out on the other side. "I'll carry him," decided Benny, as the Scarecrow made an unsuccessful attempt to walk. The live statue was really beginning to enjoy all these strange adventures and excitements. "Hurry!" he puffed, picking up the poor, soggy straw man. "That monster's coming. I hear him." Before they had reached the end of the second cave, Quiberon with a flop and flash came plunging through the water-fall. "How dare you run away?" sizzled the monster. As the water poured over his fire-breathing nose, steam came rolling in hot clouds toward Trot and her friends. "Faster! Faster! You go on!" urged Benny. "I'll stop him." With the stifling steam curling round her head, Trot ran as never before, all the way through the second cavern and rushed headlong into a narrow passageway that opened out between two rocks. Benny meanwhile, realizing that they could never outdistance Quiberon, stopped directly in his path, first placing the Scarecrow on a little ledge beside him. With a snort that shook seven sapphire rocks from the roof, Quiberon opened his monstrous mouth, and without a moment's hesitation the stone man stepped in. The Scarecrow, water soaked and helpless though he was, could not help admiring the courage of his new friend. Down came the jaws of the great fear-fish. Crunch! Crunch! Crunch! Then, there was a howl of anger and pain and eight red tusks lay on the floor of the cavern.
