my boots. A dozen times there were soft rustles and scrapes at the airlock; then sounds of hurried retreat. But at last a mass of gray-pink tendrils intruded over the threshold. And we saw the stalked eyes, faintly luminous in the shadowy interior of the lock. Grotesquely up-ended on its tentacles, the monster seemed to flow into the cabin. Over its mouth-palps was the cup of what must have been its oxygen mask. What was clearly the muzzle of some kind of pistol, smoothly machined, was held ready by a mass of tendrils that suggested Gorgon hair. Behind the first monster was a second, similarly armed. Behind him was a third. After that I lost count, as the horde, impelled by fear to grab control in one savage rush, spilled into the cabin with a dry-leaf rustle. ll my instincts urged me to yank my automatic out of my belt and let go at that flood of horror. Yes, that was in me, although I'd been in intimate association with Etl for four years. Psychologists say that no will power could keep a man's reflexes from withdrawing his hand from a hot stove for very long. And going for my gun seemed almost a reflex action. There was plenty of sound logic to back up the urge to shoot. In the presence of the unfathomable, how could you replace the tried defenses of instinct with intellectual ideas of good will? On the other hand, to shoot now would be suicide and ruin our hopes, besides. So maybe there'd have to be human sacrifices to faith between the planets. If we succeeded in following the plan, our faith would be proven either right or wrong. If we didn't act passively, the failure would be partly our fault. In any case, if we didn't get back to Earth, hatred and fear of the Martians would inevitably arise there, whether it had been the Martians' fault or ours. The message that Miller had left for newscast might only give people the self-righteous attitude that Earthly intentions had been good. If another expedition ever came to Mars, it might shoot any inhabitants on sight, and maybe get wiped out itself. Still, how could we know that the Martians weren't preparing the kind of invasion of Earth that has been imagined so often? It was a corny notion, but the basis for it remained sound. Mars was a dying world. Couldn't the Martians still want a new planet to move to? All these old thoughts popped back into my head during that very bad moment. And if I was almost going for my pistol, how much worse was it for Craig, Klein
