Two dark objects, around which were wrapped several folds of the terrible arms, Andy guessed to be Mark and Jack, and when he was a faint glow coming from them he was sure they were the boys, the gleams coming from the lamps in their helmets.

Warily the hunter approached the creature. If he had hoped to take it unawares he was disappointed, for, when he had come within ten feet, holding his improvised lance outstretched ready for a deadly thrust, the creature shot out two long arms toward Andy.

Now the battle began. The snake-like feelers, armed with big saucer shaped suckers, lashed about in the water, seeking to clasp the hunter in their deadly embrace. But Andy, who had fought many kinds of wild animals on land, did not lose his presence of mind in confronting this beast of the sea.

Nimbly, in spite of the handicap of the heavy diving suit, Andy dodged the arms. Watching his chance he thrust at one, and the sharp knife severed the end. But another arm shot out, while the wounded one was drawn in, and the battle was as much against the old hunter as before.

Once more he thrust his lance, and this time he severed one of the arms close to the ugly body. The creature, in its rage and pain, redoubled its efforts to clasp Andy.

The hunter decided to try to get to closer quarters where he could use his spear on the body of the beast. He stooped down and wiggled along on the bottom of the cave. But the creature saw him, and darted an arm out to pull the old man in. Andy squirmed to one side, and then, being as close as he desired, he rose to his feet and, drawing back the pole thrust it with all his force straight at the centre of the whitish-yellow body that was like a horrible lump of soft fat directly in front of him.

At the first touch of the knife the creature squirted out an inky substance that made the water about it as black as night. Andy could not see, but he could feel that the lance was still in the body. He pulled it back a little and thrust again and again, turning it around to enlarge the wound he had made.

Then, what he had feared all along happened. Two of the creatures arms found him, and he felt the terrible pressure as they wound themselves about him, the sucker-plates clinging fast. Yet in it all he did not lose his presence of mind, nor did he let go of the pole.

Tighter and tighter the arms clasped him. He struggled with all his strength but he was in a grip more powerful than that of a boa constrictor. Suddenly the pole he was holding snapped off. He let go the useless end and pulled the shorter part, to which the knife was bound, toward him. Andy felt his senses beginning to leave him, but he determined to make one more effort.

One hand was free, that holding the knife. With his last remaining strength he cut and slashed at the arms of the creature that were clasped about him.
