“I know what you’re thinking,” Seevers said. “That’s what we thought too, at first.
Then Felger came up with this very fine dust.
Fine as they are, those lines are rows of pictograph symbols.
You can make them out vaguely with a good reading glass, even with this coarse stuff.
It’s magnetic printing—like two-dimensional wire-recording.
Evidently, the animals that printed it had either very powerful eyes, or a magnetic sense.”
“Anyone understand it?”
“Princeton staff was working on it when the world went crazy.
They figured out enough to guess at what I’ve just told you.
They found five different shell-messages among a dozen or so spheres.
One of them was a sort of a key.
A symbol equated to a diagram of a carbon atom.
Another symbol equated to a pi in binary numbers.
Things like that—about five hundred symbols, in fact. Some we couldn’t figure.
Then they defined other symbols by what amounted to blank-filling quizzes.
Things like—‘A star is…’ and there would be the unknown symbol.
We would try to decide whether it meant ‘hot,’ ‘white,’ ‘huge,’ and so forth.”
“And you managed it?”
“In part.
The ruthless way in which the missiles were opened destroyed some of the clarity.
The senders were guilty of their own brand of anthropomorphism.
They projected their own psychology on us. They expected us to open the things shell by shell, cautiously, and figure out the text before we went further.
Heh!
What happens?
Some machinist grabs one, shakes it, weighs it, sticks it on a lathe, and—brrrrrr!
Our curiosity is still rather apelike. Stick our arm in a gopher hole to see if there’s a rattlesnake inside.”
There was a long silence while Paul stood peering over the patterns on the shell.
“Why haven’t people heard about this?” he asked quietly.
“Heard about it!” Seevers roared. “And how do you propose to tell them about it?”
Paul shook his head.
It was easy to forget that Man had scurried away from his presses and his broadcasting stations and his railroads, leaving his mechanical creatures to sleep in their own rust while he fled like a bee-stung bear before the strange terror.
“What, exactly, do the patterns say, Doctor?”
“I’ve told you some of it—the evolutionary origin of the neuroderm parasites.
We also pieced together their reasons for launching the missiles across space—several thousand years ago.
Their sun was about to flare into a supernova.
They worked out a theoretical space-drive, but they couldn’t fuel it—needed some element that was scarce in their system.
They could get to their outer planet, but that wouldn’t help much.
So they just cultured up a batch of their parasite-benefactors, rolled them into these balls, and fired them like charges of buckshot at various stars.
Interception-course, naturally.
They meant to miss just a little, so that the projectiles would swing into lone elliptical orbits around the suns—close enough in to intersect the radiational ‘life-belt’ and eventually cross paths with planets whose orbits were near-circular.
Looks like they hit us on the first pass.”
“You mean they weren’t aiming at Earth in particular?”
“Evidently not.
They couldn’t know we were here.
Not at a range like that. Hundreds of light-years.
They just took a chance on several stars.
Shipping off their pets was sort of a last ditch stand against extinction—symbolic, to be sure—but a noble gesture, as far as they were concerned.
A giving away of part of their souls. Like a man writing his will and leaving his last worldly possession to some unknown species beyond the stars.
Imagine them standing there—watching the projectiles being fired out toward deep space.
There goes their inheritance, to an unknown heir, or perhaps to no one.
