The chains were long enough to permit him to move a yard or so in any direction and by feeling the walls he found he was in a small circular room that had no outlet except the passage by which he had entered, and that was now closed by the door of steel. This was the end of the series of caverns and corridors.
It was now that the horror of his situation occurred to the boy with full force. But he resolved not to submit to his fate without a struggle, and realizing that he possessed the Blue Pearl, which gave him marvelous strength, he quickly broke the chains and set himself free of the handcuffs. Next he twisted the steel door from its hinges, and creeping along the short passage, found himself in the third cave.
But now the dim light, which had before guided him, had vanished; yet on peering into the gloom of the cave he saw what appeared to be two round disks of flame, which cast a subdued glow over the floor and walls. By this dull glow he made out the form of an enormous man, seated in the center of the cave, and he saw that the iron grating had been removed, permitting the man to enter.
The giant was unclothed and its limbs were thickly covered with coarse red hair. The round disks of flame were its two eyes and when it opened its mouth to yawn Inga saw that its jaws were wide enough to crush a dozen men between the great rows of teeth.
Presently the giant looked up and perceived the boy crouching at the other side of the cavern, so he called out in a hoarse, rude voice:
"Come hither, my pretty one. We will wrestle together, you and I, and if you succeed in throwing me I will let you pass through my cave."
The boy made no reply to the challenge. He realized he was in dire peril and regretted that he had lent the Pink Pearl to King Rinkitink. But it was now too late for vain regrets, although he feared that even his great strength would avail him little against this hairy monster. For his arms were not long enough to span a fourth of the giant's huge body, while the monster's powerful limbs would be likely to crush out Inga's life before he could gain the mastery.
Therefore the Prince resolved to employ other means to combat this foe, who had doubtless been placed there to bar his return. Retreating through the passage he reached the room where he had been chained and wrenched the iron post from its socket. It was a foot thick and four feet long, and being of solid iron was so heavy that three ordinary men would have found it hard to lift.
Returning to the cavern, the boy swung the great bar above his head and dashed it with mighty force full at the giant. The end of the bar struck the monster upon its forehead, and with a single groan it fell full length upon the floor and lay still.
When the giant fell, the glow from its eyes faded away, and all was dark. Cautiously, for Inga was not sure the giant was dead, the boy felt his way toward the opening that led to the middle cavern. The entrance was narrow and the darkness was intense, but, feeling braver now, the boy stepped boldly forward. Instantly the floor began to sink beneath him and in great alarm he turned and made a leap that enabled him to grasp the rocky sides of the wall and regain a footing in the passage through which he had just come.
Scarcely had he obtained this place of refuge when a mighty crash resounded throughout the cavern and the sound of a rushing torrent came from far below. Inga felt in his pocket and found several matches, one of which he lighted and held before him. While it flickered he saw that the entire floor of the cavern had fallen away, and knew that had he not instantly regained his footing in the passage he would have plunged into the abyss that lay beneath him.
By the light of another match he saw the opening at the other side of the cave and the thought came to him that possibly he might leap across the gulf. Of course, this could never be accomplished without the marvelous strength lent him by the Blue Pearl, but Inga had the feeling that one powerful spring might carry him over the chasm into safety.
