No wonder men went berserk under hours of unwinking Alien scrutiny—watching them as they marched in a colorfully uniformed lodge parade, or fished through a hole in the ice, as they painfully maneuvered a giant transcontinental jet to a noiseless landing or sat in sweating, serried rows chanting to a single, sweating man to “knock it out of the park and sew the whole thing up!” No wonder they seized rusty shotgun or gleaming rifle and sped shot after vindictive shot into a sky poisoned by the contemptuous curiosity of a brown, yellow or vermilion “bottle.”

Not that it made very much difference. It did give a certain release to nerves backed into horrible psychic corners. But the Aliens didn’t notice, and that was most important. The Aliens went right on watching, as if all this shooting and uproar, all these imprecations and weapon-wavings, were all part of the self-same absorbing show they had paid to witness and were determined to see through if for nothing else than the occasional amusing fluff some member of the inexperienced cast might commit.

The Aliens weren’t injured, and the Aliens didn’t feel attacked. Bullets, shells, buckshot, arrows, pebbles from a slingshot—all Man’s miscellany of anger passed through them like the patient and eternal rain coming in the opposite direction. Yet the Aliens had solidity somewhere in their strange bodies. One could judge that by the way they intercepted light and heat. And also—

Also by the occasional ping.

Every once in a while, someone would evidently have hurt an Alien slightly. Or more probably just annoyed it by some unknown concomitant of rifle-firing or javelin-throwing.

There would be the barest suspicion of a sound—as if a guitarist had lunged at a string with his fingertip and decided against it one motor impulse too late. And, after this delicate and hardly heard ping, quite unspectacularly, the rifleman would be weaponless. He would be standing there sighting stupidly up along his empty curled fingers, elbow cocked out and shoulder hunched in, like a large oafish child who had forgotten when to end the game. Neither his rifle nor a fragment of it would ever be found. And—gravely, curiously, intently—the Alien would go on watching.

The ping seemed to be aimed chiefly at weapons. Thus, occasionally, a 155mm howitzer was pinged, and also, occasionally, unexpectedly, it might be a muscular arm, curving back with another stone, that would disappear to the accompaniment of a tiny elfin note. And yet sometimes—could it be that the Alien, losing interest, had become careless in its irritation?—the entire man, murderously violent and shrieking, would ping and be no more.

It was not as if a counterweapon were being used, but a thoroughly higher order of reply, such as a slap to an insect bite. Hebster, shivering, recalled the time he had seen a black tubular Alien swirl its amber dots over a new substreet excavation, seemingly entranced by the spectacle of men scrabbling at the earth beneath them.

A red-headed, blue-shirted giant of construction labor had looked up from Manhattan’s stubborn granite just long enough to shake the sweat from his eyelids. So doing, he had caught sight of the dot-pulsing observer and paused to snarl and lift his pneumatic drill, rattling it in noisy, if functionless, bravado at the sky. He had hardly been noticed by his mates, when the long, dark, speckled representative of a race beyond the stars turned end over end once and pinged.

The heavy drill remained upright for a moment, then dropped as if it had abruptly realized its master was gone. Gone? Almost, he had never been. So thorough had his disappearance been, so rapid, with so little flicker had he been snuffed out—harming and taking with him nothing else—that it had amounted to an act of gigantic and positive noncreation.
