It moved on toward the denser fracas among the ants. Suddenly it raised its ghastly saw-toothed forelegs in an extraordinary gesture. It was the mantis's spectral attitude, which seemed a pose of holding out its arms in benediction. But its eyes remained blind-seeming and enigmatic,—again like dark glasses.
Then it struck. Daintily, it dined upon an ant. Upon another. Upon another and another and another.
From one direction parties of agitated and hurrying black objects appeared at the edge of the mist. They were ants of a special caste,—warrior-ants with huge mandibles designed for fighting in defense of their city and its social system and its claim to fragments of dead centipedes. From another direction other parties of no less truculent warriors moved with the swiftness and celerity of a striking task-force. All the air was filled with the deep-bass notes of something huge, booming beyond visibility, and the noises as of sticks trailed against picket fences, and hootings which were produced by the rubbing of serrated leg-joints against chitinous diaphragms. But now a new tumult arose.
From forty disputatious formicidae, whining angrily at each other over the stinking remains of the monster Moran had killed, the number of ants involved in the quarrel became hundreds. But more and more arrived. The special caste of warriors bred for warfare was not numerous enough to take care of the provocative behavior of foreign foragers. There was a general mobilization in both unseen ant-city states. They became nations in arms. Their populations rushed to the scene of conflict. The burrows and dormitories and eating-chambers of the underground nations were swept clean of occupants. Only the nurseries retained a skeleton staff of nurses—the nurseries and the excavated palace occupied by the ant-queen and her staff of servants and administrators. All the resources of two populous ant-nations were flung into the fray.
From a space of a hundred yards or less, containing mere dozens of belligerent squabblers, the dirty-white ground of the fungus-plain became occupied by hundreds of snapping, biting combatants. They covered—they fought over—the half of an acre. There were contending battalions fighting as masses in the center, while wings of fighting creatures to right and left were less solidly arranged. But reinforcements poured out of the mist from two directions, and momently the situation changed. Presently the battle covered an acre. Groups of fresh fighters arriving from the city to the right uttered shrill stridulations and charged upon the flank of their enemies. Simultaneously, reinforcements from the city to the left flung themselves into the fighting-line near the center.
Formations broke up. The battle disintegrated into an indefinite number of lesser combats; troops or regiments fighting together often moved ahead with an appearance of invincibility, but suddenly they broke and broke again until there was only a complete confusion of unorganized single combats in which the fighters rolled over and over, struggling ferociously with mandible and claw to destroy each other. Presently the battle raged over five acres. Ten. Thousands upon thousands of black, glistening, stinking creatures tore at each other in murderous ferocity. Whining, squealing battle-cries arose and almost drowned out the deeper notes of larger but invisible creatures off in the mist.
Moran and Harper got back to the Nadine by a wide detour past warriors preoccupied with each other just before the battle reached its most savage stage. In that stage, the space-yacht was included in the battleground. Fights went on about its landing-fins. Horrifying duels could be followed by scrapings and bumpings against its hull. From the yacht's ports the fighting ants looked like infuriated machines, engaged in each other's destruction. One might see a warrior of unidentified allegiance with its own abdomen ripped open, furiously rending an enemy without regard to its own mortal wound. There were those who had literally been torn in half, so that only head and thorax remained, but they fought on no less valiantly than the rest.
At the edges of the fighting such cripples were more numerous. Ants with antenna shorn off or broken, with legs missing, utterly doomed,—they sometimes wandered forlornly beyond the fighting, the battle seemingly forgotten. But even such dazed and incapacitated casualties came upon each other. If they smelled alike, they ignored each other. Every ant-city has its particular smell which its inhabitants share. Possession of the national odor is at once a certificate of citizenship in peacetime and a uniform in war. When such victims of the battle came upon enemy walking wounded, they fought.
And the giant praying mantis remained placidly and invulnerably still. It plucked single fighters from the battle and dined upon them while they struggled, and plucked other fighters, and consumed them. It ignored the battle and the high purpose and self-sacrificing patriotism of the ants. Immune to them and disregarded by them, it fed on them while the battle raged.
Presently the gray light overhead turned faintly pink, and became a deeper tint and then crimson. In time there was darkness. The noise of battle ended. The sounds of the day diminished and ceased, and other monstrous outcries took their place.
There were bellowings in the blackness without the Nadine. There were chirpings become baritone, and senseless uproars which might be unbelievable modifications of once-shrill and once-tranquil night-sounds of other worlds. And there came a peculiar, steady, unrhythmic pattering sound. It seemed like something falling upon the blanket-like upper surface of the soil.
Moran opened the airlock door and thrust out a torch to see. Its intolerably bright glare showed the battlefield abandoned. Most of the dead and wounded had been carried away. Which, of course, was not solicitude for the wounded or reverence for the dead heroes. Dead ants, like dead centipedes, were booty of the only kind the creatures of this world could know. The dead were meat. The wounded were dead before they were carried away.
Moran peered out, with Carol looking affrightedly over his shoulder. The air seemed to shine slightly in the glare of the torch. The pattering sound was abruptly explained. Large, slow, widely-separated raindrops fell heavily and steadily from the cloud-banks overhead. Moran could see them strike. Each spot of wetness glistened briefly. Then the rain-drop was absorbed by the ground.
But there were other noises than the ceaseless tumult on the ground. There were sounds in the air; the beating of enormous wings. Moran looked up, squinting against the light. There were things moving about the black sky. Gigantic things.
Something moved, too, across the diminishingly lighted surface about the yacht. There were glitterings. Shining armor. Multi-faceted eyes. A gigantic, horny, spiked object crawled toward the torch-glare, fascinated by it. Something else dived insanely. It splashed upon the flexible white surface twenty yards away, and struggled upward and took crazily off again. It careened blindly.
It hit the yacht, a quarter-ton of night-flying beetle. The air seemed filled with flying things. There were moths with twenty-foot wings and eyes which glowed like rubies in the torch's light. There were beetles of all sizes from tiny six-inch things to monsters in whom Moran did not believe even when he saw them. All were drawn by the light which should not exist under the cloud-bank. They droned and fluttered and performed lunatic evolutions, coming always closer to the flame.
Moran cut off the torch and closed the lock-door from the inside.
"We don't load bessendium tonight," he said with some grimness. "To have no light, with what crawls about in the darkness, would be suicide. But to use lights would be worse. If you people are going to salvage the stuff in that wreck, you'll have to wait for daylight. At least then you can see what's coming after you."
