The Last Evolution (7)

By: John W. Campbell
November 17, 2020

John W. Campbell, the visionary (if also racist and conservative) editor who helped jump-start science fiction’s so-called Golden Age when he assumed control of the pulp magazine Astounding in 1937, began his career as a (late) Radium Age sf writer. “The Last Evolution” was published in Amazing Stories in 1932; as its US copyright was not renewed, the story is now in public domain. HILOBROW is pleased to serialize it here, for our readers.



Then — from one after another of the Earth-ships, in quick succession, a new ray reached out — the ray of green radiance that killed all life forms, and ship after ship of that interstellar host was dead and lifeless. Dozens — till suddenly they ceased to feel those beams, as a strange curtain of waving blankness spread out from the ships, and both induction-beam and death-beam alike turned as aside, each becoming useless. From the outsiders came beams, for now that their slowly created screen of blankness was up, they could work through it, while they remained shielded perfectly.

Now it was the screens of the Earth-machines that flamed in defense. As at the one command, they darted suddenly toward the ship each attacked — nearer — then the watchers from a distance saw them disappear, and the screens back on Earth went suddenly blank.

Half an hour later, nine thousand six hundred and thirty-three titanic ships moved majestically on.

They swept over Earth in a great line, a line that reached from pole to pole, and from each the pale green beams reached down, and all life beneath them was swept out of existence.


In Denver, two humans watched the screens that showed the movement of the death and instant destruction. Ship after ship of the enemy was falling, as hundreds of the terrestrial machines concentrated all their enormous energies on its screen of blankness.

“I think, Roal, that this is the end,” said Trest.

“The end — of man.” Roal’s eyes were dreaming again. “But not the end of evolution. The children of men still live — the machines will go on. Not of man’s flesh, but of a better flesh, a flesh that knows no sickness, and no decay, a flesh that spends no thousands of years in advancing a step in its full evolution, but overnight leaps ahead to new heights. Last night we saw it leap ahead, as it discovered the secret that had baffled man for seven centuries, and me for one and a half. I have lived — a century and a half. Surely a good life, and a life a man of six centuries ago would have called full. We will go now. The beams will reach us in half an hour.”

Silently, the two watched the flickering screens.

Roal turned, as six large machines floated into the room, following F-2.

“Roal — Trest — I was mistaken when I said no screen could stop that beam of Death. They had the screen, I have found it, too — but too late. These machines I have made myself. Two lives alone they can protect, for not even their power is sufficient for more. Perhaps — perhaps they may fail.”

The six machines ranged themselves about the two humans, and a deep-toned hum came from them. Gradually a cloud of blankness grew — a cloud, like some smoke that hung about them. Swiftly it intensified.

“The beams will be here in another five minutes,” said Trest quietly.

“The screen will be ready in two,” answered F-2.

The cloudiness was solidifying, and now strangely it wavered, and thinned, as it spread out across, and like a growing canopy, it arched over them. In two minutes it was a solid, black dome that reached over them and curved down to the ground about them.

Beyond it, nothing was visible. Within, only the screens glowed still, wired through the screen.

The beams appeared, and swiftly they drew closer. They struck, and as Trest and Roal looked, the dome quivered, and bellied inward under them.

F-2 was busy. A new machine was appearing under his lightning force-beams. In moments more it was complete, and sending a strange violet beam upwards toward the roof.

Outside more of the green beams were concentrating on this one point of resistance. More — more —

The violet beam spread across the canopy of blackness, supporting it against the pressing, driving rays of pale green.

Then the gathering fleet was driven off, just as it seemed that that hopeless, futile curtain must break, and admit a flood of destroying rays. Great ray projectors on the ground drove their terrible energies through the enemy curtains of blankness, as light illumines and disperses darkness.

And then, when the fleet retired, on all Earth, the only life was under that dark shroud!
