It was late dusk and the reddened clouds overhead were deepening steadily toward black. Dark shadows hung everywhere. The clay cliff cut off all vision to one side, but elsewhere Burl could see outward until the graying haze blotted out the horizon. Here and there, bees droned homeward to hive or burrow. Sometimes a slender, graceful wasp passed overhead, its wings invisible by the swiftness of their vibration.

A few butterflies lingered hungrily in the distance, seeking the few things they could still feast upon. No moth had wakened yet to the night. The cloud-bank grew more sombre. The haze seemed to close in and shrink the world that Burl could see.

He watched, raging, for the sight that would provide him with the triumph to end all triumphs among his followers. The soft, down-reaching fingers of the night touched here and there and the day ended at those spots. Then, from the heart of the deep redness to the west a flying creature came. It was a beautiful thing—a yellow emperor butterfly—flapping eastward with great sail-like velvet wings that seemed black against the sunset. Burl saw it sweep across the incredible sky, alight delicately, and disappear behind a mass of toadstools clustered so thickly they seemed nearly a hillock and not a mass of growing things.

Then darkness closed in completely, but Burl still stared where the yellow emperor had landed. There was that temporary, utter quiet when day-things were hidden and night-things had not yet ventured out. Fox-fire glowed. Patches of pale phosphorescence—luminous mushrooms—shone faintly in the dark.

Presently Burl moved through the night. He could imagine the yellow emperor in its hiding-place, delicately preening slender limbs before it settled down to rest until the new day dawned. He had noted landmarks, to guide himself. A week earlier and his blood would have run cold at the bare thought of doing what he did now. In mere cool-headed detachment he would have known that what he did was close to madness. But he was neither cool-headed nor detached.

He crossed the clear ground before the low cliff. But for the fox-fire beacons he would have been lost instantly. The slow drippings of rain began. The sky was dead black. Now was the time for night-things to fly, and male tarantulas to go seeking mates and prey. It was definitely no time for adventuring.

Burl moved on. He found the close-packed toadstools by the process of running into them in the total obscurity. He fumbled, trying to force his way between them. It could not be done; they grew too close and too low. He raged at this impediment. He climbed.

This was insanity. Burl stood on spongy mushroom-stuff that quivered and yielded under his weight. Somewhere something boomed upward, rising on fast-beating wings into blackness. He heard the pulsing drone of four-inch mosquitos close by. He moved forward, the fungus support swaying, so that he did not so much walk as stagger over the close-packed mushroom heads. He groped before him with spear and panted a little. There was a part of him which was bitterly afraid, but he raged the more furiously because if once he gave way even to caution, it would turn to panic.

Burl would have made a strange spectacle in daylight gaudily clothed as he was in soft blue fur and velvet cloak, staggering over swaying insecurity, coddling ferocity in himself against the threat of fear.

Then his spear told him there was emptiness ahead. Something moved, below. He heard and felt it stirring the toadstool-stalks on which he stood.

Burl raised his spear, grasping it in both hands. He plunged down with it, stabbing fiercely.

The spear struck something vastly more resistant than any mushroom could be. It penetrated. Then the stabbed thing moved as Burl landed upon it, flinging him off his feet, but he clung to the firmly imbedded weapon. And if his mouth had opened for a yell of victory as he plunged down, the nature of the surface on which he found himself, and the kind of movement he felt, turned that yell into a gasp of horror.

It wasn't the furry body of a butterfly he had landed on; his spear hadn't pierced such a creature's soft flesh. He had leaped upon the broad, hard back of a huge, meat-eating, nocturnal beetle. His spear had pierced not the armor, but the leathery joint-tissue between head and thorax.

The giant creature rocketed upward with Burl clinging to his spear. He held fast with an agonized strength. His mount rose from the blackness of the ground into the many times more terrifying blackness of the air. It rose up and up. If Burl could have screamed, he would have done so, but he could not cry out. He could only hold fast, glassy-eyed.

Then he dropped. Wind roared past him. The great insect was clumsy at flying. All beetles are. Burl's weight and the pain it felt made its flying clumsier still. There was a semi-liquid crashing and an impact. Burl was torn loose and hurled away. He crashed into the spongy top of a mushroom and came to rest with his naked shoulder hanging halfway over some invisible drop. He struggled.

He heard the whining drone of his attempted prey. It rocketed aloft again. But there was something wrong with it. With his weight applied to the spear as he was torn free, Burl had twisted the weapon in the wound. It had driven deeper, multiplying the damage of the first stab.

The beetle crashed to earth again, nearby. As Burl struggled again, the mushroom-stalk split and let him gently to the ground.

He heard the flounderings of the great beetle in the darkness. It mounted skyward once more, its wing-beats no longer making a sustained note. It thrashed the air irregularly and wildly.

Then it crashed again.

There was seeming silence, save for the steady drip-drip of the rain. And Burl came out of his half-mad fear: he suddenly realized that he had slain a victim even more magnificent than a spider, because this creature was meat.

He found himself astonishedly running toward the spot where the beetle had last fallen.

But he heard it struggle aloft once more. It was wounded to death. Burl felt certain of it this time. It floundered in mid-air and crashed again.

He was within yards of it before he checked himself. Now he was weaponless, and the gigantic insect flung itself about madly on the ground, striking out with colossal wings and limbs, fighting it knew not what. It struggled to fly, crashed, and fought its way off the ground—ever more weakly—then smashed again into mushrooms. There it floundered horribly in the darkness.

Burl drew near and waited. It was still, but pain again drove it to a senseless spasm of activity.

Then it struck against something. There was a ripping noise and instantly the close, peppery, burning smell of the red dust was in the air. The beetle had floundered into one of the close-packed red puffballs, tightly filled with the deadly red spores. The red dust would not normally have been released at night. With the nightly rain, it would not travel so far or spread so widely.

Burl fled, panting.

Behind him he heard his victim rise one last time, spurred to impossible, final struggle by the anguish caused by the breathed-in red dust. It rose clumsily into the darkness in its death-throes and crashed to the ground again for the last time.

In time to come, Burl and his followers might learn to use the red-dust puffballs as weapons—but not how to spread them beyond their normal range. But now, Burl was frightened. He moved hastily sidewise. The dust would travel down-wind. He got out of its possible path.

There could be no exultation where the red dust was. Burl suddenly realized what had happened to him. He had been carried aloft an unknown though not-great distance, in an unknown direction. He was separated from his tribe, with no faintest idea how to find them in the darkness. And it was night.

He crouched under the nearest huge toadstool and waited for the dawn, listening dry-throated for the sound of death coming toward him through the night.

But only the wind-beats of night-fliers came to his ears, and the discordant notes of gray-bellied truffle-beetles as they roamed the mushroom thickets, seeking the places beneath which—so their adapted instincts told them—fungoid dainties, not too much unlike the truffles of Earth, awaited the industrious miner. And, of course, there was that eternal, monotonous dripping of the raindrops, falling at irregular intervals from the sky.

Red puffballs did not burst at night. They would not burst anyhow, except at one certain season of their growth. But Burl and his folk had so far encountered the over-hasty ones, bursting earlier than most. The time of ripeness was very nearly here, though. When day came again, and the chill dampness of the night was succeeded by the warmth of the morning, almost the first thing Burl saw in the gray light was a tall spouting of brownish-red stuff leaping abruptly into the air from a burst red parchment-like sphere.

He stood up and looked anxiously all around. Here and there, all over the landscape, slowly and at intervals, the plumes of fatal red sprang into the air. There was nothing quite like it anywhere else. An ancient man, inhabiting Earth, might have likened the appearance to that of a scattered and leisurely bombardment. But Burl had no analogy for them.

He saw something hardly a hundred yards from where he had hidden during the night. The dead beetle lay there, crumpled and limp. Burl eyed it speculatively. Then he saw something that filled him with elation. The last crash of the beetle to the ground had driven his spear deeply between the joints of the corselet and neck. Even if the red dust had not finished the creature, the spear-point would have ended its life.

He was thrilled once more by his superlative greatness. He made due note that he was a mighty slayer. He took the antennae as proof of his valor and hacked off a great barb-edged leg for meat. And then he remembered that he did not know how to find his fellow-tribesmen. He had no idea which way to go.

Even a civilized man would have been at a loss, though he would have hunted for an elevation from which to look for the cliff hiding-place of the tribe. But Burl had not yet progressed so far. His wild ride of the night before had been at random, and the chase after the wounded beetle no less dictated by chance. There was no answer.

He set off anxiously, searching everywhere. But he had to be alert for all the dangers of an inimical world while keeping, at the same time, an extremely sharp eye out for bursting red puffballs.

At the end of an hour he thought he saw familiar things. Then he recognized the spot. He had come back to the dead beetle. It was already the center of a mass of small black bodies which pulled and hacked at the tough armor, gnawing out great lumps of flesh to be carried to the nearest ant-city.

Burl set off again, very carefully avoiding any place that he recognized as having been seen that morning. Sometimes he walked through mushroom-thickets—dangerous places to be in—and sometimes over relatively clear ground colored exotically with varicolored fungi. More than once he saw the clouds of red stuff spurting in the distance. Deep anxiety filled him. He had no idea that there were such things as points of the compass. He knew only that he needed desperately to find his tribesfolk again.

They, of course, had given him up for dead. He had vanished in the night. Old Tama complained of him shrilly. The night, to them, meant death. Jon quaked watchfully all through it. When Burl did not come to the feast of mushroom that Jon and Dor had brought back, they sought him. They even called timidly into the darkness. They heard the throbbing of huge wings as a great creature rose desperately into the sky, but they did not associate that sound with Burl. If they had, they would have been instantly certain of his fate.

As it was, the tribe's uneasiness grew into terror which rapidly turned to despair. They began to tremble, wondering what they would do with no bold chieftain to guide them. He was the first man to command allegiance from others in much too long a period, on the forgotten planet, but the submission of his followers had been the more complete for its novelty. His loss was the more appalling. Burl had mistaken the triumphant shout of the foragers. He'd thought it independence of him—rivalry. Actually, the men dared to shout only because they felt secure under his leadership. When they accepted the fact that he had vanished—and to disappear in the night had always meant death—their old fears and timidity returned. To them it was added despair.

They huddled together and whispered to one another of their fright. They waited in trembling silence through all the long night. Had a hunting-spider appeared, they would have fled in as many directions as there were people, and undoubtedly all would have perished. But day came again, and they looked into each other's eyes and saw the self-same fear. Saya was probably the most pitiful of the group. Her face was white and drawn beyond that of any one else.

They did not move when day brightened. They remained about the bee-tunnels, speaking in hushed tones, huddled together, searching all the horizon for enemies. Saya would not eat, but sat still, staring before her in numbed grief. Burl was dead.

Atop the low cliff a red puffball glistened in the morning light. Its tough skin was taut and bulging, resisting the pressure of the spores within. Slowly, as the morning wore on, some of the moisture that kept the skin stretchable dried. The parchment-like stuff contracted. The tautness of the spore-packed envelope grew greater. It became insupportable.

With a ripping sound, the tough skin split across and a rush of the compressed spores shot skyward.

The tribesmen saw and cried out and fled. The red stuff drifted down past the cliff-edge. It drifted toward the humans. They ran from it. Jon and Tama ran fastest. Jak and Cori and the other were not far behind. Saya trailed, in her despair.

Had Burl been there, matters would have been different. He had already such an ascendancy over the minds of the others that even in panic they would have looked to see what he did. And he would have dodged the slowly drifting death-cloud by day, as he had during the night. But his followers ran blindly.

As Saya fled after the others she heard shrieks of fright to the left and ran faster. She passed by a thick mass of distorted fungi in which there was a sudden stirring and panic lent wings to her feet. She fled blindly, panting. Ahead was a great mass of stuff—red puffballs—showing here and there among great fanlike growths, some twelve feet high, that looked like sponges.

She fled past them and swerved to hide herself from anything that might be pursuing by sight. Her foot slipped on the slimy body of a shell-less snail and she fell heavily, her head striking a stone. She lay still.

Almost as if at a signal a red puffball burst among the fanlike growths. A thick, dirty-red cloud of dust shot upward, spread and billowed and began to settle slowly toward the ground again. It moved as it settled flowing over the inequalities of die ground as a monstrous snail or leach might have done, sucking from all breathing creatures the life they had within them. It was a hundred yards away, then fifty, then thirty....

Had any member of the tribe watched it, the red dust might have seemed malevolently intelligent. But when the edges of the dust-cloud were no more than twenty yards from Saya's limp body, an opposing breeze sprang up. It was a vagrant, fitful little breeze that halted the red cloud and threw it into some confusion, sending it in a new direction. It passed Saya without hurting her, though one of its misty tendrils reached out as if to snatch at her in slow-motion. But it passed her by.

Saya lay motionless on the ground. Only her breast rose and fell shallowly. A tiny pool of red gathered near her head.

Some thirty feet from where she lay, there were three miniature toadstools in a clump, bases so close together that they seemed but one. From between two of them, however, two tufts of reddish thread appeared. They twinkled back and forth and in and out. As if reassured, two slender antennae followed, then bulging eyes and a small, black body with bright-red scalloped markings upon it.

It was a tiny beetle no more than eight inches long—a sexton or burying-beetle. Drawing near Saya's body it scurried onto her flesh. It went from end to end of her figure in a sort of feverish haste. Then it dived into the ground beneath her shoulder, casting back a little shower of hastily-dug dirt as it disappeared.

Ten minutes later, another small creature appeared, precisely like the first. Upon the heels of the second came a third. Each made the same hasty examination and dived under her unmoving form.

Presently the ground seemed to billow at a spot along Saya's side and then at another. Ten minutes after the arrival of the third beetle, a little rampart had reared itself all about Saya's body, following her outlines precisely. Then her body moved slightly, in little jerks, seeming to settle perhaps half an inch into the ground.

The burying-beetles were of that class of creatures which exploited the bodies of the fallen. Working from below, they excavated the earth. When there was a hollow space below they turned on their backs and thrust up with their legs, jerking at the body until it sank into the space they had made ready. The process would be repeated until at last all their dead treasures had settled down below the level of the surrounding ground. The loosened dirt then fell in at the sides, completing the inhumation. Then, in the underground darkness, it was the custom for the beetles to feast magnificently, gorging themselves upon the food they had hidden from other scavengers—and of course rearing their young also upon its substance.

Ants and flies were rivals of these beetles and not infrequently the sexton-beetles came upon carrion after ants had taken their toll, and when it already swarmed with maggots. But in this case Saya was not dead. The fact that she still lived, though unconscious, was the factor that had given the sexton-beetles this splendid opportunity.

She breathed gently and irregularly, her face drawn with the sorrow of the night before, while the desperately hurrying beetles swarmed about beneath her body, channelling away the soil so she would sink lower and lower into it. She descended slowly, a half-inch by a half-inch. The bright-red tufts of thread appeared again and a beetle made its way to the open air. It moved hastily about, inspecting the progress of the work.

It dived below again. Another inch and, after a long time, another, were excavated.

Matters still progressed when Burl stepped out from a group of overshadowing toadstools and halted. He cast his eyes over the landscape and was struck by its familiarity. He was, in fact, very near the spot he had left the night before in that maniacal ride on the back of a flying beetle. He moved back and forth, trying to account for the feeling of recognition.

He saw the low cliff, then, and moved eagerly toward it, passing within fifty feet of Saya's body, now more than half-buried in the ground. The loose dirt around the outline of her figure was beginning to topple in little rivulets upon her. One of her shoulders was already half-screened from view. Burl passed on, unseeing.

He hurried a little. In a moment he recognized his location exactly. There were the mining-bee burrows. There was a thrown-away lump of edible mushroom, cast aside as the tribesfolk fled.

His feet stirred up a fine dust, and he stopped short. A red puffball had burst here. It fully accounted for the absence of the tribe, and Burl sweated in sudden fear. He thought instantly of Saya. He went carefully to make sure. This was, absolutely, the hiding place of the tribe. There was another mushroom-fragment. There was a spear, thrown down by one of the men in his flight. Red dust had settled upon the spear and the mushroom-fragments.

Burl turned back, hurrying again, but taking care to disturb the dust no more than he could possibly help.

The little excavation into which Saya was sinking inch by inch was not in his path. Her body no longer lay above the ground, but in it. Burl went by, frantic with anxiety about the tribe, but about Saya most of all.

Her body quivered and sank a fraction into the ground. Half a dozen small streams of earth were tumbling upon her. In minutes she would be wholly hidden from view.

Burl went to beat among the mushroom-thickets, in quest of the bodies of his tribesfolk. They could have staggered out of the red dust and collapsed beyond. He would have shouted, but the deep sense of loneliness silenced him. His throat ached with grief. He searched on....

There was a noise. From a huge clump of toadstools—perhaps the very one he had climbed over in the night—there came the sound of crashings and the breaking of the spongy stuff. Twin tapering antennae appeared, and then a monster beetle lurched into the open space, its ghastly mandibles gaping sidewise.

It was all of eight feet long and supported by six crooked, saw-toothed legs. Huge, multiple eyes stared with preoccupation at the world. It advanced deliberately with clankings and clashings as of a hideous machine. Burl fled on the instant, running directly away from it.

A little depression lay in the ground before him. He did not swerve, but made to jump over it. As he leaped he saw the color of bare flesh, Saya, limp and helpless, sinking slowly into the ground with tricklings of dirt falling down to cover her. It seemed to Burl that she quivered a little.

Instantly there was a terrific struggle within Burl. Behind him was the giant meat-eating beetle; beneath him was Saya whom he loved. There was certain death lurching toward him on evilly crooked legs—and the life he had hoped for lay in a shallow pit. Of course he thought Saya dead.

Perhaps it was rage, or despair, or a simple human madness which made him act otherwise than rationally. The things which raise humans above brute creation, however, are only partly reasonable. Most human emotions—especially the creditable ones—cannot be justified by reason, and very few heroic actions are based upon logical thought.

Burl whirled as he landed, his puny spear held ready. In his left hand he held the haunch of a creature much like the one which clanked and rattled toward him. With a yell of insane defiance—completely beyond justification by reason—Burl flung that meat-filled leg at the monster.

It hit. Undoubtedly, it hurt. The beetle seized it ferociously. It crushed it. There was meat in it, sweet and juicy.

The beetle devoured it. It forgot the man standing there, waiting for death. It crunched the leg-joint of a cousin or brother, confusing the blow with the missile that had delivered it. When the tidbit was finished it turned and lumbered off to investigate another mushroom thicket. It seemed to consider then an enemy had been conquered and devoured and that normal life could go on.

Then Burl stopped quickly, and dragged Saya from the grave the sexton-beetles had labored so feverishly to provide for her. Crumbled soil fell from her shoulders, from her face, and from her body. Three little eight-inch beetles with black and red markings scurried for cover in terrified haste. Burl carried Saya to a resting-place of soft mould to mourn over her.

He was a completely ignorant savage, save that he knew more of the ways of insects than anybody anywhere else—the Ecological Service, which had stocked this planet, not being excepted. To Burl the unconsciousness of Saya was as death itself. Dumb misery smote him, and he laid her down gently and quite literally wept. He had been beautifully pleased with himself for having slain one flying beetle. But for Saya's seeming death, he would have been almost unbearable with pride over having put another to flight. But now he was merely a broken-hearted, very human young man.

But a long time later Saya opened her eyes and looked about bewilderedly.

They were in considerable danger for some time after that, because they were oblivious to everything but each other. Saya rested in half-incredulous happiness against Burl's shoulder as he told her jerkily of his attempt on a night-bound butterfly, which turned out to be a flying beetle that took him aloft. He told of his search for the tribe and then his discovery of her apparently lifeless body. When he spoke of the monster which had lurched from the mushroom thicket, and of the desperation with which he had faced it, Saya looked at him with warm, proud eyes. But Burl was abruptly struck with the remarkable convenience of that discovery. If his tribesmen could secure an ample supply of meat, they might defend themselves against attack by throwing it to their attackers. In fact, insects were so stupid that almost any object thrown quickly enough and fast enough, might be made to serve as sacrifices instead of themselves.

A timid, frightened whisper roused them from their absorption. They looked up. The boy Dik stood some distance away, staring at them wide-eyed, almost convinced that he looked upon the living dead. A sudden movement on the part of either of them would have sent him bolting away. Two or three other bobbing heads gazed affrightedly from nearby hiding-places. Jon was poised for flight.

The tribe had come back to its former hiding-place simply as a way to reassemble. They had believed both Burl and Saya dead, and they accepted Burl's death as their own doom. But now they stared.

Burl spoke—fortunately without arrogance—and Dik and Tet came timorously from their hiding-places. The others followed, the tribe forming a frightened half-circle about the seated pair. Burl spoke again and presently one of the bravest—Cori—dared to approach and touch him. Instantly a babble of the crude labial language of the tribe broke out. Awed exclamations and questions filled the air.

But Burl, for once, showed some common sense. Instead of a vainglorious recital, he merely cast down the long tapering antennae of the flying-beetle. They looked, and recognized their origin.

Then Burl curtly ordered Dor and Jak to make a chair of their hands for Saya. She was weak from her fall and the loss of blood. The two men humbly advanced and obeyed. Then Burl curtly ordered the march resumed.

They went on, more slowly than on previous days, but none-the-less steadily. Burl led them across-country, marching in advance with a matter-of-fact alertness for signs of danger. He felt more confidence than ever before. It was not fully justified, of course. Jon now retrieved the spear he had discarded. The small party fairly bristled with weapons. But Burl knew that they were liable to be cast away as impediments if flight seemed necessary.

As he led the way Burl began to think busily in the manner that only leaders find necessary. He had taught his followers to kill ants for food, though they were still uneasy about such adventures. He had led them to attack great yellow grubs upon giant cabbages. But they had not yet faced any actual danger, as he had done. He must drive them to face something....

The opportunity came that same day, in late afternoon. To westward the cloud-bank was barely beginning to show the colors that presage nightfall, when a bumble-bee droned heavily overhead, making for its home burrow. The little, straggling group of marching people looked up and saw the scanty load of pollen packed in the stiff bristles of the bee's hind-legs. It sped onward heavily, its almost transparent wings mere blurs in the air.

It was barely fifty feet above the ground. Burl dropped his glance and tensed. A slender-waisted wasp was shooting upward from an ambush among the noisome fungi of this plain.

The bee swerved and tried to escape. The wasp over-hauled it. The bee dodged frantically. It was a good four feet in length,—as large as the wasp, certainly—but it was more heavily built and could not make the speed of which the wasp was capable. It dodged with less agility. Twice, in desperation, it did manage to evade the plunging dives of the wasp, but the third time the two insects grappled in mid-air almost over the heads of the humans.

They tumbled downward in a clawing, biting, tangle of bodies and legs. They hit the ground and rolled over and over. The bee struggled to insert her barbed sting in the more supple body of her adversary. She writhed and twisted desperately.

But there came an instant of infinite confusion and the bee lay on her back. The wasp suddenly moved with that ghastly skilled precision of a creature performing an incredible feat instinctively, apparently unaware that it is doing so. The dazed bee was swung upright in a peculiarly artificial pose. The wasp's body curved, and its deadly, rapier-sharp sting struck....

The bee was dead. Instantly. As if struck dead by lightning. The wasp had stung in a certain place in the neck-parts where all the nerve-cords pass. To sting there, the wasp had to bring its victim to a particular pose. It was precisely the trick of a desnucador, the butcher who kills cattle by severing the spinal cord. For the wasp's purposes the bee had to be killed in this fashion and no other.

Burl began to give low-toned commands to his followers. He knew what was coming next, and so did they. When the sequel of the murder began he moved forward, his tribesmen wavering after him. This venture was actually one of the least dangerous they could attempt, but merely to attack a wasp was a hair-raising idea. Only Burl's prestige plus their knowledge made them capable of it.

The second act of the murder-drama was gruesomeness itself. The pirate-wasp was a carnivore, but this was the season when the wasps raised young. Inevitably there was sweet honey in the half-filled crop of the bee. Had she arrived safely at the hive, the sweet and sticky liquid would have been disgorged for the benefit of bee-grubs. The wasp avidly set to work to secure that honey. The bee-carcass itself was destined for the pirate-wasp's own offspring, and that squirming monstrosity is even more violently carnivorous than its mother. The parent wasp set about abstracting the dead bee's honey, before taking the carcass to its young one, because honey is poisonous to the pirate-wasp's grub. Yet insects cannot act from solicitude or anything but instinct. And instinct must be maintained by lavish rewards.

So the pirate-wasp sought its reward—an insane, insatiable, gluttonous satisfaction in the honey that was poison to its young. The wasp foiled its murdered victim upon its back again and feverishly pressed on the limp body to force out the honey. And this was the reason for its precise manner of murder. Only when killed by the destruction of all nerve-currents would the bee's body be left limp like this. Only a bee killed in this exact fashion would yield its honey to manipulation.

The honey appeared, flowing from the dead bee's mouth. The wasp, in trembling, ghoulish ecstasy, devoured it as it appeared. It was lost to all other sights or sensations but its feast.

And this was the moment when Burl signalled for the attack. The tribesmen's prey was deaf and blind and raptured. It was aware of nothing but the delight it savored. But the men wavered, nevertheless, when they drew near. Burl was first to thrust his spear powerfully into the trembling body.

When he was not instantly destroyed the others took courage. Dor's spear penetrated the very vitals of the ghoul. Jak's club fell with terrific force upon the wasp's slender waist. There was a crackling, and the long, spidery limbs quivered and writhed. Then Burl struck again and the creature fell into two writhing halves.

They butchered it rather messily, but Burl noticed that even as it died, sundered and pierced with spears, its long tongue licked out in one last rapturous taste of the honey that had been its undoing.

Some time later, burdened with the pollen laden legs of the great bee, the tribe resumed its journey.

Now Burl had men behind him. They were still timid and prone to flee at the least alarm, but they were vastly more dependable than they had been. They had attacked and slain a wasp whose sting would have killed any of them. They had done battle under the leadership of Burl, whose spear had struck the first blow. They were sharers of his glory and, therefore, much more nearly like the followers of a chieftain ought to be.

Their new spirit was badly needed. The red puffballs were certainly no less numerous in the new territory the tribe traversed than in the territory they had left. And the season of their ripening' was further advanced. More and more of the ground showed the deadly rime of settled death-dust. To stay alive was increasingly difficult. When the full spore-casting season arrived, it would be impossible. And that season could not be far away.

The very next day after the killing of the wasp, survival despite the red dust had begun to seem unimaginable. Where, earlier, one saw a red-dust cloud bursting here and there at intervals, on this day there was always a billowing mass of lethal vapor in the air. At no time was the landscape free of a moving mist of death. Usually there were three or four in sight at once. Often there were half a dozen. Once there were eight. It could be guessed that in one day more they would ripen in such monstrous numbers that anything which walked or flew or crawled must breathe in the spores and perish.

And that day, just at sunset, the tribe came to the top of a small rise in the ground. For an hour they had been marching and countermarching to avoid the suddenly-billowing clouds of dust. Once they had been nearly hemmed in when three of the dull-red mists seemed to flow together, enclosing the three sides of a circle. They escaped then only by the most desperate of sprinting.

But now they came to the little hillock and halted. Before them stretched a plain, all of four miles wide, colored a brownish brick-red by the red puffballs. The tribe had seen mushroom forests—they had lived in them—and knew of the dangers that lurked there. But the plain before them was not simply dangerous; it was fatal. To right and left it stretched as far as the eye could see, but away on its farther edge Burl caught a glimpse of flowing water.

Over the plain itself a thin red haze seemed to float. It was simply a cloud of the deadly spores, dispersed and indefinite, but constantly replenished by the freshly bursting puffballs. While the tribesfolk stood and watched, thick columns of dust rose here and there and at the other place, too many to count. They settled again but left behind enough of the fine powder to keep a thin red haze over all the plain. This was a mass of literally millions of the deadly growths. Here was one place where no carnivorous beetles roamed and where no spiders lurked. There were nothing here but the sullen columns of dust and the haze that they left behind.

And of course it would be nothing less than suicide to try to go back.
