Harry and I sprang forward.

As we did so the eyes closed and the reptile began to move backward with incredible swiftness, lashing about on the ground before us with other tentacles similar to the one that had captured Desiree.

I cried out to Harry to avoid them. He did not answer, but rushed blindly forward.

Desiree's agonized shrieks rose to the pitch of madness.

The eyes were closed, leaving but a vague mark for our spears, and besides, there was the danger of striking Desiree. We were barely able to keep pace with the thing as it receded swiftly down the broad pa.s.sage. Desiree had twisted her body half round, and her face was turned toward us, shadowy as a ghost. Then her head fell forward and hung loosely and her lips were silent. She had fainted.

The thing moved swifter than ever; we were barely able to keep up with it. Harry made a desperate leap forward.

I cried out a warning, but one of the writhing tentacles swept against him and knocked him to the ground. He was up again on the instant and came rushing up from behind.

Suddenly the pa.s.sage broadened until the walls were no longer visible; we had entered another cavern. I heard the sound of running water somewhere ahead of us. The pace of the reptile had not slackened for an instant.

Harry had again caught up with us, and as he ran at my side I saw him raise his spear aloft; but I caught his arm and held it.

"Desiree!" I panted.

Her body covered the only part of the thing that presented a fair mark.

Harry swore, but his arm fell.

"To the side!" he gasped. "We can't get at it here!"

I saw his meaning and followed at his heels as he swerved suddenly to the right and sprang forward in an attempt to get past the reptile's head.

But in our eagerness we forgot caution and went too close. I felt one of the snaky tentacles wrap itself round my legs and body, and raised my voice in a warning to Harry, but too late. He, too, was ensnared, and a moment later we had both been lifted bodily from the ground and swung through the air to the side of Desiree. She was still unconscious.

I writhed and twisted desperately, but that muscular coil held me firmly as a band of steel, tight against the huge and hideous head.

Harry was on the other side of Desiree, not three feet from me. I could see his muscles strain and pull in his violent efforts to tear himself free. I had given it up.

But suddenly, quite near my shoulder, I saw the lid suddenly begin to raise itself from one of the terrible eyes. I was almost on top of the thing and a little above it. I turned my head aside and called to Harry.

"The eye!" I gasped. "To your right! The spear! Are your arms free?"

Then as I saw he understood, I turned a quarter of the way round--as far as I could get--and raised my spear the full extent of my arm, and brought it down with every ounce of my strength into the very center of the glowing eye beneath me.

At the same moment I saw Harry's arm descend and the flash of his spear. The point of my own had sunk until the copper head was completely buried.

I grasped the shaft and pulled and twisted it about until it finally was jerked forth. From the opening it had made there issued a black stream.

Suddenly the body of the reptile quivered convulsively. The head rolled from side to side. There was a quick tightening of the tentacle round my body until my bones felt as though they were being crushed into shapelessness; and as suddenly it loosened.

Other tentacles lashed and beat on the ground furiously. The reptile's swift backward movement halted jerkily. I made a desperate effort to tear myself free. The tentacle quivered and throbbed violently, and suddenly flew apart like a released spring, and I fell to the ground.

In an instant Harry was at my side, and we both leaped forward with our spears, slashing at the tentacle which still held Desiree in its grasp.

Others writhed on the ground about our feet, but feebly. There came a sudden cry from Harry, and his spear clattered on the ground as he opened his arms to receive Desiree's unconscious body, which came tumbling down with the severed coil still wrapped about it.

But there was life in the reptile's immense body. It staggered and swayed from side to side in drunken agony. Its monstrous head rolled about, sweeping the air in a prodigious circle. The poison of its breath came to us in great puffs. There was something supremely horrible about the thing in its very helplessness, and I was shuddering violently as I stooped to help Harry lift Desiree from the ground and carry her away.

We did not go far, for we were barely able to carry her. We laid her on the hard rock with her head in Harry's lap. Her body was limp as a rag.

For many minutes we worked over her, rubbing her temples and wrists, and pressing the nerve centers at the back of the neck, but without effect.

"She is dead," said Harry with a curious calm.

I shook my head.

"She has a pulse--see! But we must find that water. I think she isn't injured; it is her weakened condition from the lack of food that keeps her so. Wait for me."

I started out across the cavern in the direction from which the sound of the water appeared to come, bearing off to the right from the huge, quivering form of the monster whose gigantic body rose and fell on the ground with a force that seemed to shake the very walls of the cavern.

I found the stream with little difficulty, not far away, and returned to Harry. Together we carried Desiree to its edge. The blood was stubborn, and for a long time refused to move, but the cold water at length revived her; her eyes slowly opened, and she raised her hand to her head with a faltering gesture.

But she was extremely weak, and we saw that the end was near unless nourishment could be found for her.

I stayed by her side, with my arms round her shoulders, and Harry set out with one of the spears. He bore off to the left, toward the spot where the body of the immense reptile lay; I was too far away to see it in the darkness.

"It isn't possible that the thing is fit to eat," I had objected, and he had answered me with a look which I understood, and was silenced.

Soon a sound as of a scuffle on the rocks came through the darkness from the direction he had taken. I called out to ask if he needed me, but there was no answer. Ten minutes longer I waited, while the sound continued unabated. Once I heard the clatter of his spear on the rock.

I was just rising to my feet to run to the scene when suddenly he appeared in the semidarkness. He was coming slowly, and was dragging along the ground what appeared to be the form of some animal. Another minute and he stood at my side as I sat holding Desiree.

"A peccary!" I cried, bending over the body of the four-footed creature that lay at his feet. "How the deuce did it ever get down here?"

"Peccary--my aunt!" observed Harry, bending down to look at Desiree.

"Do peccaries live in the water? Do they have snouts like catfish?

This animal is my own invention. There's about ten million more of 'em over there making a gorgeous banquet off our late lamented friend. And now, let's see."

He knelt down by the still warm body and with the point of his spear ripped it open from neck to rump. Desiree stirred about in my arms.

"Gad, that smells good!" cried Harry.

I shuddered.

He dragged the thing a few feet away, and I heard him slashing away at it with his spear. A minute later he came running over to us with his hands full of something.

That was not exactly a pretty meal. How Desiree, in her frightfully weakened condition, ever managed to get the stuff down and keep it there is beyond me. But she did, and I was not behind her. And, after all, it was fresh. Harry said it was "sweet." Well, perhaps it was.

We bathed Desiree's hands and face and gave her water to drink, and soon after she pa.s.sed into a seemingly healthy sleep. There was about ten pounds of meat left. Harry washed it in the stream and stowed it away on a rock beneath the surface of the water. Then he announced his intention of going back for more.

"I'm going with you," I declared. "Here--help me fix Desiree."

"Hardly," said Harry. "Didn't I say there are millions of those things over there? Anyway, there are hundreds. If they should happen to scatter in this direction and find her, she wouldn't stand a chance.

You take the other spear and stay here."

So I sat still, with Desiree's body in my arms, and waited for him. My sensations were not unpleasant. I could actually feel the blood quicken in my veins.
