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.
