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.
