“We’ve never satisfactorily defined life,” one of his instructors had told Brown shortly after he started the three grueling years of training which had been necessary, “so we can’t very well build a foolproof machine for detecting it. That’s why we’ve left room for 105 pounds of dead weight.”

“Meaning me?”

“Meaning you.”

“And I’m your foolproof machine for detecting life?”

“Let’s say you’re the closest we can come to it at present. We’re banking everything on this first trip. It’ll be at least eighteen [91] months later before we can get a second ship into space. So it’s up to you to get everything you can … some evidence of life, preferably animal, if possible. With public support it’ll be a hell of a lot easier squeezing appropriations out of Congress for the next ship and to get public support we need the biggest possible play in the newspapers. If anything is newsworthy on Mars it should be evidence of life … even plant life.”

So here he was, 105 pounds of concentrated knowledge and anticipation, itching with the desire for action and also from more basic causes having to do with two months confinement in a small space with a minimum of water.

“Life is most probable at the poles

,” the instructor had said. “You won’t be able to stay long so we’ll try to set you down right at the South Pole. You won’t have room to bring back specimens. So keep your eyes open and absorb everything you see. Don’t forget anything. What you bring back in your mind weighs nothing.”

“It’s just sitting there,” the observing banks reported, “and the red flame has gone out.”

“Is it safe now?” enquired the speculative bank.

“In what way?”

“Is it safe to go near that thing?”

“It’s very huge,” ventured the observing banks unasked. There was a stir of activity which encompassed practically all except the most simple units and which lasted for perhaps five minutes while the speculative bank’s last question was processed.

Finally the interpretive bank reluctantly admitted, “We can’t arrive at a positive answer. Too many unknown elements are present. We don’t know for sure what caused the flame, when it might start again, or what, if anything, is inside.”

“But you said it was a work of intelligence. Doesn’t that mean Rell would be inside?”

“Not necessarily. They could have constructed the thing to operate itself.”

It was just then that the observing banks reported, “It’s opening.”

The speculative bank quickly responded, “This is an emergency. We must be able to observe from close up. We’ll have to approach it.”

“The entire mind?” enquired the disciplinary corps.

The speculative bank hesitated. “No, we’ll need to split up. One-fifth of us will go, the rest remain here. It’s a short distance and we’ll still be able to continue in complete contact.”

Those who were to go were quickly sorted out and Raeillo/ee13 was quite thrilled to find he and Raellu//2 were included in the scouting party.

The group set off briskly toward their objective but had moved hardly one hundred yards when a vertigo seemed to overtake them. Raeillo/ee13 found himself swimming helplessly in a vortex of darkness and isolation, blanked off from not only the group-mind and his bank but also from Raellu//2. Frantically he grasped for some sort of stasis, but dependence on the group-mind was too ingrained and he was unable to stir his
