They crouched motionless, frozen. No hope in either flight or fight; on the open ground, they would be run down in no time, and they had no weapons--even the notion of a weapon, as something apart from the fighting machine that carried it, was alien to their thinking. The enemy vehicle rolled into full view and nosed slowly along the base of the mound; its motor whining questingly, only a few yards of gentle slope between it and the huddled pair. Its vision-ports glinted redly in the sunset glow, and Dworn could almost feel the raking of murderous eyes from behind them.... Like the other machines of this kind he had seen it was small and without armor--it couldn't weigh more than a couple of thousand pounds, and it carried no guns. From the vantage of his armed and armored beetle, he had regarded its like as flimsy and harmless-looking.... But now he realized for the first time how helpless a mere human was against such a thing, and, with an irrepressible shudder, how easily the grappling and cutting-tools this one was equipped with might be employed for--dismantling--flesh and blood. The machine paused momentarily. Then its engine revved up again. It rolled on past, giving no sign of excitement, and vanished beyond the hillside. "Dworn, Dworn, it didn't see us!" Qanya was sobbing with relief. Dworn was staring after the enemy, brows puzzledly drawn downward. The sounds from the other side of the mound went on uninterrupted--a clangor of metal, the prolonged shrilling of a cutting-torch, where evidently they were at work breaking up the smashed spider-vehicle. He said huskily, "Something's very queer about them.... Wait. I've _got_ to take a look." Qanya glanced at him in quick alarm as he started wriggling to the crest of the sandhill. Then she followed silently, and peered over the top beside him. Twilight was descending, but they could still see easily enough what went on out there. Not a hundred yards away, the little machines swarmed about the spider, bringing their various wrecking equipment into play to dismantle it rapidly under the watchers' eyes. Torches flared, winches tugged at fragments of the shattered monster. An aluminum cylinder with a serrated alligator snout rolled triumphantly away, bearing aloft the shank of a great steel leg.... But Dworn's attention was riveted by what was happening closer at hand. Here, near the tunnel-entrance that opened just below their observation point, lay the two crawlers which the runaway spider had disabled. One of these, the one which had merely been overturned and severely dented, was already being dragged away, wheels still helplessly in the air, by a towing-machine. The other had been smashed beyond repair. Around it several of the new arrivals were busy, callously and efficiently beginning to take it apart. Dworn watched them at it, and the dreadful suspicion that had budded in his mind ripened into a monstrous certainty.
