"Routine training mission. The jet strayed over the closed zone, though. That's the puzzle."
"Any other information?"
"The pilot said something about his air hose dissolving. Vibration, or something. His last communication was bizarre."
"Like he was crazy?" Stone asked.
"Like that," Robertson said.
"Is there a team at the wreck site now?"
"Yes, we're waiting for information from them. It could come at any time."
"Pass it along," Stone said. And then he stopped. "If a 7-11 was ordered, instead of a 7-12," he said, "then you have troops in the area around Piedmont."
"National Guard, yes."
"That's pretty damned stupid," Stone said.
"Look, Jeremy, I agree--"
"When the first one dies," Stone said, "I want to know when, and how. And most especially, where. The wind there is from the east predominantly. If you start losing men west of Piedmont--"
"I'll call, Jeremy," Robertson said.
The conversation ended, and the team shuffled out of the conference room. Hall remained behind a moment, going through some of the rolls in the box, noting the messages. The majority were unintelligible to him, a weird set of nonsense messages and codes. After a time he gave up; he did so before he came upon the reprinted news item concerning the peculiar death of Officer Martin Willis, of the Arizona highway patrol.

22. The Analysis
WITH THE NEW PRESSURES OF TIME, THE RESULTS of spectrometry and amino-acid analysis, previously of peripheral interest, suddenly became matters of major concern. It was hoped that these analyses would tell, in a rough way, how foreign the Andromeda organism was to earth life forms.
It was thus with interest that Leavitt and Burton looked over the computer printout, a column of figures written on green paper:

What all this meant was simple enough. The black rock contained hydrogen, carbon, and oxygen, with significant amounts of sulfur, silicon, and selenium, and with trace quantities of several other elements.
The green spot, on the other hand, contained hydrogen, carbon, nitrogen, and oxygen. Nothing else at all. The two men found it peculiar that the rock and the green spot should be so similar in chemical makeup. And it was peculiar that the green spot should contain nitrogen, while the rock contained none at all.
The conclusion was obvious: the "black rock" was not rock at all, but some kind of material similar to earthly organic life. It was something akin to plastic.
And the green spot, presumably alive, was composed of elements in roughly the same proportion as earth life On earth, these same four elements-- hydrogen, carbon, nitrogen, and oxygen-- accounted for 99 per cent of all the elements in life organisms.
The men were encouraged by these results, which suggested similarity between the green spot and life on earth. Their hopes were, however, short-lived as they turned to the amino-acid analysis:

"Damn," Leavitt said, staring at the printed sheet. "Will you look at that."
"No amino acids," Burton said. "No proteins."
"Life without proteins," Leavitt said. He shook his head; it seemed as if his worst fears were realized.
On earth, organisms had evolved by learning to carry out biochemical reactions in a small space, with the help of protein enzymes. Biochemists were now learning to duplicate these reactions, but only by isolating a single reaction from all others.
Living cells were different. There, within a small area, reactions were carried out that provided energy, growth, and movement. There was no separation, and man could not duplicate this any more than a man could prepare a complete dinner from appetizers to dessert by mixing together the ingredients for everything into a single large dish, cooking it, and hoping to separate the apple pie from the cheese dip later on.
Cells could keep the hundreds of separate reactions straight, using enzymes. Each enzyme was like a single worker in a kitchen, doing just one thing. Thus a baker could not make a steak, any more than a steak griller could use his equipment to prepare appetizers.
But enzymes had a further use. They made possible chemical reactions that otherwise would not occur. A biochemist could duplicate the reactions by using great heat, or great pressure, or strong acids. But the human body, or the individual cell, could not tolerate such extremes of environment. Enzymes, the matchmakers of life, helped chemical reactions to go forward at body temperature and atmospheric pressure.
Enzymes were essential to life on earth. But if another form of life had learned to do without them, it must have evolved in a wholly different way.
Therefore, they were dealing with an entirely alien organism.
And this in turn meant that analysis and neutralization would take much, much longer.

In the room marked MORPHOLOGY, Jeremy Stone removed the small plastic capsule in which the green fleck had been imbedded. He set the now-hard capsule into a vise, fixing it firmly, and then took a dental drill to it, shaving away the plastic until he exposed bare green material.
