Its wing-beats no longer kept up a sustained note. They thrashed the air irregularly and wildly. The flight was zigzag and uncertain, and though longer than the first had been, it ended similarly, in a heavy fall. Another period of floundering, and the beetle took to the air again just before Burl arrived at the spot.

It was obviously seriously hurt, and Burl forgot the dangers of the night in his absorption in the chase. He darted after his prey, fleet-footed and agile, taking chances that in cold blood he would never have thought of.

Twice, in the pain-racked struggles of the monster beetle, he arrived at the spot where the gigantic insect flung itself about madly, insanely, fighting it knew not what, striking out with colossal wings and legs, dazed and drunk with agony. And each time it managed to get aloft in flight that was weaker and more purposeless.

Crazy, fleeing from the torturing spear that pierced its very vitals, the beetle blundered here and there, floundering among the mushroom thickets in spasms that were constantly more prolonged and more agonized, but nevertheless flying heavily, lurching drunkenly, managing to graze the tops of the toadstools in one more despairing, tormented flight.

And Burl followed, aflame with the fire of the chase, arriving at the scene of each successive, panic-stricken struggle on the ground just after the beetle had taken flight again, but constantly more closely on the heels of the weakening monster.

At last he came up panting, and found the giant lying upon the earth, moving feebly, apparently unable to rise. How far he was from the tribe, Burl did not know, nor did the question occur to him at the moment. He waited for the beetle to be still, trembling with excitement and eagerness. The struggles of the huge form grew more feeble, and at last ceased. Burl moved forward and grasped his spear. He wrenched at it to thrust again.

In an instant the beetle had roused itself, and was exerting its last atom of strength, galvanized into action by the agony caused by Burl's seizure of the spear. A great wing-cover knocked Burl twenty feet, and flung him against the base of a mushroom, where he lay, half stunned. But then a strangely pungent scent came to his nostrils—the scent of the red mushrooms!

He staggered to his feet and fled, while behind him the gigantic beetle crashed and floundered—Burl heard a tearing and ripping sound. The insect had torn the covering of one of the red mushrooms, tightly packed with the fatal red dust. At the noise, Burl's speed was doubled, but he could still hear the frantic struggles of the dying beetle grow to a very crescendo of desperation.

The creature broke free and managed to rise in a final flight, fighting for breath and life, weakened and tortured by the spear and the horrible spores of the red mushrooms. Then it crashed suddenly to the earth and was still. The red dust had killed it.

In time to come, Burl might learn to use the red dust as poison gas had been used by his ancestors of thirty thousand years before, but now he was frightened and alone, lost from his tribe, and with no faintest notion of how to find them. He crouched beneath a huge toadstool and waited for dawn, listening with terrified apprehension for the ripping sound that would mean the bursting of another of the red mushrooms.
