Dennis swung his steel club. It clashed against the scarcely less hard mandibles of the worker, not harming them, but seeming to daze the insect a little.

Jim followed the act by plunging his longer spear into the soft body. No words were wasted by the two men. It was a fight for life again, with the odds even more heavily against them than they had been in the ruler's lair.

Behind them, blocking the only exit they had any chance whatever of reaching, the guard continued its clashing mandible duty. If only it, too, would join in the blind search for the trespa.s.sers, thus giving them an opportunity of slipping out! But the monster gave no indication of doing such a thing.

Another worker termite flung its bulk at them. Its mandibles, tiny in comparison with those of the great guards but still capable of slicing either of the men in two, snapped perilously close to Jim's body. There was a second's concerted action: Dennis' club lashed against the thing's head, Jim's spear tore into the vulnerable body.

Ringing them round, the main band of the termites moved closer. They moved slowly, in no hurry, apparently only too sure the enemy could not possibly get away from them. And the two worker termites killed were mere incidents compared to the avalanche of mandible and horn that would be on them in about thirty seconds.

However, the two dead termites gave Jim a sudden inspiration. He glanced from the carca.s.ses to the mechanically moving, deadly jaws of the guard that barred the nearest exit.

"Denny," he panted, "feed it this."

He pointed first toward the nearest carca.s.s and then toward the rock-crushing, steadily snapping jaws.

"I'll try to hold the bridge here--"

But Dennis was on his way, catching Jim's idea with the first gesture.

He stooped down, and caught the dead termite by two of its legs. Close to two hundred pounds the ma.s.s weighed; but strength is an inconstant thing, and increases or decreases according to the vital needs of life-preservation.

Clear of the floor, Denny lifted the bulk, and with its repulsive weight clasped in his arms, he advanced toward the mighty guard.

Behind him, Jim glared desperately at the third termite that was about to attack. No feeble worker this, but one of the most colossal of all the Queen's guard.

Towering over Jim, mandibles wide open and ready to smash over its prey, the giant reared toward him. And behind him came the main body of the horde. It was painfully evident that the clash with the lone soldier would be the last single encounter. After that the hundreds of the herd would be on the men, tearing and trampling them to bits.

During the thing's steady, inexorable approach, which had taken far less time than that required to tell of it, Jim had clenched his fingers around his spear and calculated as to the best way to hold the monster off for just the few seconds needed by Denny to try the plan suggested.

The monster ended its slow advance in a lunge, that, for all its great bulk, was lightning quick. But a shade more quickly, Jim sidestepped the terrible mandibles, leaped back along the armored body till he had reached the unarmored rear, and thrust his spear home with all his force.

The hideous guard reared with pain and rage. But this was no worker termite, to be killed with a thrust. As though nothing had happened, the huge hulk wheeled around. The mandibles crashed shut with deafening force over the s.p.a.ce Jim had occupied but an instant before.

And now the inner circle of the multiple ring of death was within a few yards. Jim leaped to put himself behind the living barrier of the attacking soldier. But it was only a matter of a few seconds now, before he and Denny would be caught in the blind bull charges of the wounded soldier or by the surrounding ring of maddened termites.

"Denny?" he shouted imploringly over his shoulder, not daring to take his eyes off the danger in front of him.

"Soon!" he heard Dennis pant.

The entomologist had got almost up to the twelve-foot jaws that closed the exit. He paused a moment, gathering strength. Then he heaved the soft ma.s.s of the dead termite into the clashing mandibles.

"Jim!" he cried, as the burden left his arms.

Jim turned, raced the few yards intervening between the ring of death and the doorway. Together they waited to see if their forlorn hope would work....

It could not have lasted more than a second, that wait, yet it seemed at least ten minutes. And then both cried aloud--and crouched to repeat the maneuver that had saved them from death when they had first entered this insect h.e.l.l.

For the enormous, smashing jaws had caught the body of the worker termite with ferocious eagerness, and were worrying the inanimate carca.s.s with terrible force.

The great jaws were occupied just an instant before the monster sensed that it was one of his own kind that he was mangling so thoroughly. But in that instant Jim had slid on his chest along the floor past the armored head and shoulders, and Dennis had leaped to follow.

But Dennis was not to get off so lightly.

The charging ring of termites had closed completely in by now. The snapping mandibles of the nearest one were up to him. They opened; shut.

They caught Denny on the back swing, knocking him six feet away instead of slicing him wide open. Denny got to his feet almost before he had landed; but between him and the exit was the bulk of the termite that had felled him, and in the doorway the guard had dropped the body it was slashing to bits, and had recommenced its slashing jaw movements.

"Jim! For G.o.d's sake...." shrieked the doomed man.

Beside himself, he managed to hurdle clear over the ma.s.sive insect between him and the doorway. But there he stopped, with the guard's great mandibles fanning the air less than a foot from him. "Jim!" came the agonized cry again.

And behind the gigantic termite, in the tunnel, with at least a possibility of safety lying open before him, Jim heard and answered the call.

Savagely he plunged his spear into the unarmored rear of the guard, tore it out, thrust again....

The thing heaved and struggled to turn, shaking the tunnel with its rasping anger--and taking its attention at last away from the duty of closing that tunnel mouth.

With no room to run and slide, Denny fell to the floor and commenced to creep through the narrow s.p.a.ce between the trampling guard's bulk and the wall. He felt his left arm and shoulder go numb as he was crushed for a fleeting instant against the wood part.i.tion. Broken, he thought dimly. The collar-bone. But still he kept moving on.

He moved in a haze of pain and weakness. He did not see that he had pa.s.sed clear of the menacing hulk--that his slow crawling had been multiplied in results by the fact that the termite guard had finally, stopped trying to turn in the narrow pa.s.sage and had rushed ahead into the Queen's chamber, to turn there and come dashing back. He did not see that Jim was finally disarmed and completely helpless, with his spear buried beyond recovery in the bulk of the maddened guard. He hardly felt Jim's supporting arm as it was thrust under him, to half drag and half lead him along the tunnel away from the horde behind.

He only knew that they were moving forward, with the din behind them--as the grim cohorts of the Queen fought to all crowd ahead in the narrow pa.s.sage at once--keeping pace with them in spite of all they could do to make haste. And he only knew that finally Jim gave a great shout, and that suddenly they were standing under a rent in a tunnel roof through which sunlight was pouring.

Several worker termites were laboring to close up the c.h.i.n.k and cut off the sunlight; but these, not being of the band outraged by the destruction of the egg in the Queen's chamber, moved swiftly away as the two men advanced.

Jim reached up and tore with frantic hands at the crumbling edges of the rotten wood overhead. Ignoring his gashed and bleeding fingers, he widened the breach till he, could pull himself up through it. Then he reached down, caught Denny's sound arm, and raised him by main strength.

They were in the clear air of the outer world once more, on a terrace in the mound low down near its base.

Jim and Dennis half slid, half fell down the near terrace slope to the jungle of gra.s.s stalks beneath. And there Denny bit his lip sharply, struggled against the weakness overcoming him--and fainted.

Jim caught him up over his shoulder, and staggered forward through the jungle. Behind, the termites poured out through the broken wall in an enraged flood, braving even the sunlight and outer air in their chase of the invaders that had, profaned the Queen's chamber.

"Matt!" shouted Jim with all the strength of his lungs, forgetting that his voice could not be heard by normal human ears. "Matt!"

But if Matthew Breen could not hear, he could see. The slightest inattention at his guard duty at that second would have resulted in two deaths. But he was on the alert.
