together. There was a strangely elastic crash and crackling. They had fallen into the web beneath them.

Burl had reached the end of terror. He could be no more fear-struck. Struggling madly in the gummy coils of an immense web, which ever bound him more tightly, with a wounded creature shuddering in agony not a yard from him—yet a wounded creature that still strove to reach him with its poison fangs—Burl had reached the limit of panic.

He fought like a madman to break the coils about him. His arms and breast were greasy from the oily fish, and the sticky web did not adhere to them, but his legs and body were inextricably fastened by the elastic threads spread for just such prey as he.

He paused a moment, in exhaustion. Then he saw, five yards away, the silvery and black monster waiting patiently for him to weary himself. It judged the moment propitious. The tarantula and the man were one in its eyes, one struggling thing that had fallen opportunely into its snare. They were moving but feebly now. The spider advanced delicately, swinging its huge bulk nimbly along the web, paying out a cable after it came inexorably toward him.

Burl's arms were free, because of the greasy coating they had received. He waved them wildly, shrieking at the pitiless monster that approached. The spider paused. Those moving arms suggested mandibles that might wound or slap.

Spiders take few hazards. This spider was no exception to the rule. It drew cautiously near, then stopped. Its spinnerets became busy, and with one of its six legs, used like an arm, it flung a sheet of gummy silk impartially over both the tarantula and the man.

Burl fought against the descending shroud. He strove to thrust it away, but in vain. In a matter of minutes he was completely covered in a silken cloth that hid even the light from his eyes. He and his enemy, the giant tarantula, were beneath the same covering, though the tarantula moved but weakly.

The shower ceased. The web-spider had decided that they were helpless. Then Burl felt the cables of the web give slightly, as the spider approached to sting and suck the sweet juices from its prey.

The web yielded gently as the added weight of the black-bellied spider approached. Burl froze into stillness under his enveloping covering. Beneath the same silken shroud the tarantula writhed in agony upon the point of Burl's spear. It clashed its jaws, shuddering upon the horny barb.

Burl was quiet in an ecstasy of terror. He waited for the poison-fangs to be thrust into him. He knew the process. He had seen the leisurely fashion in which the giant spiders delicately stung their prey, then withdrew to wait without impatience for the poison to do its work.

When their victim had ceased to struggle, they drew near again, and sucked the sweet juices from the body, first from one point and then another, until what had so recently been a creature vibrant with life became a shrunken, withered husk—to be flung from the web at nightfall. Most spiders are tidy housekeepers, destroying their snares daily to spin anew.

The bloated, evil creature moved meditatively about the shining sheet of silk it had cast over the man and the giant tarantula when they fell from the cliff above. Now only the tarantula moved feebly. Its body was outlined by a bulge in the concealing shroud, throbbing faintly as it still struggled with the spear in its vitals. The irregularly rounded protuberance offered a point of attack for the web spider. It moved quickly forward, and stung.

Galvanized into fresh torment by this new agony, the tarantula writhed in a very hell of pain. Its legs, clustered about the spear still fastened into its body, struck out purposelessly, in horrible gestures of delirious suffering. Burl screamed as one of them touched him, and struggled himself.

His arms and head were free beneath the silken sheet because of the grease and oil that coated them. He clutched at the threads about him and strove to draw himself away from his deadly neighbor. The threads did not break, but they parted one from another, and a tiny opening appeared. One of the tarantula's attenuated limbs touched him again. With the strength of utter panic he hauled himself away, and the opening enlarged. Another struggle, and Burl's head emerged into the open air, and he stared down for twenty feet upon an open space almost carpeted with the chitinous remains of his present captor's former victims.

Burl's head was free, and his breast and arms. The fish slung over his shoulder had shed its oil upon him impartially. But the lower part of his body was held firm by the gummy snare of the web-spider, a snare far more tenacious than any bird-lime ever manufactured by man.

He hung in his tiny window for a moment, despairing. Then he saw, at a little distance, the bulk of the monster spider, waiting patiently for its poison to take effect and the struggling of its prey to be stilled. The tarantula was no more than shuddering now. Soon it would be still, and the black-bellied creature waiting on the web would approach for its meal.

Burl withdrew his head and thrust desperately at the sticky stuff about his loins and legs. The oil upon his hands kept it from clinging to them, and it gave a little. In a flash of inspiration, Burl understood. He reached over his shoulder and grasped the greasy fish; tore it in a dozen places and smeared himself with the now rancid exudation, pushing the sticky threads from his limbs and oiling the surface from which he had thrust it away.

He felt the web tremble. To the spider, its poison seemed to have failed of effect. Another sting seemed to be necessary. This time it would not insert its fangs into the quiescent tarantula, but would sting where the disturbance was manifest—would send its deadly venom into Burl.

He gasped, and drew himself toward his window. It was as if he would have pulled his legs from his body. His head emerged, his shoulders—half his body was out of the hole.

The colossal spider surveyed him, and made ready to cast more of its silken sheet upon him. The spinnerets became active, and the sticky stuff about Burl's feet gave way! He shot out of the opening and fell sprawling, awkwardly and heavily, upon the earth below, crashing upon the shrunken shell of a flying beetle which had fallen into the snare and had not escaped.

Burl rolled over and over, and then sat up. An angry, foot-long ant stood before him, its mandibles extended threateningly, while its antennae waved wildly in the air. A shrill stridulation filled the air.

In ages past, when ants were tiny creatures of lengths to be measured in fractions of an inch, learned scientists debated gravely if their tribe possessed a cry. They believed that certain grooves upon the body of the insects, after the fashion of those upon the great legs of the cricket, might offer the means of uttering an infinitely high-pitched sound too shrill for man's ears to catch.

Burl knew that the stridulation was caused by the doubtful insect before him, though he had never wondered how it was produced. The cry was used to summon others of its city, to help it in its difficulty or good fortune.

Clickings sounded fifty or sixty feet away. Comrades were coming to aid the pioneer. Harmless save when interfered with—all save the army ant, that is—the whole ant tribe was formidable when aroused. Utterly fearless, they could pull down a man and slay him as so many infuriated fox terriers might have done thirty thousand years before.

Burl fled, without debate, and nearly collided with one of the anchoring cables of the web from which he had barely escaped a moment before. He heard the shrill sound behind him suddenly subside. The ant, short-sighted as all ants were, no longer felt itself threatened and went peacefully about the business Burl had interrupted, that of finding among the gruesome relics beneath the spider's web some edible carrion which might feed the inhabitants of its city.

Burl sped
