   The team stared at the message in disbelief。 No one said anything for a long time。 Finally; Stone ran his fingers along the upper corner of the sheet and said in a low voice; 〃This was a 443。 That makes it an MCN transmission。 It should have rung the bell down here。〃 
   〃There's no bell on this teleprinter;〃 Leavitt said。 〃Only on Level I; at sector five。 But they're supposed to notify us whenever〃
   〃Get sector five on the inter;〃 Stone said。

   Ten minutes later; the horrified Captain Mortis had connected Stone to Robertson; the head of the President's Science Advisory mittee; who was in Houston。
 
   Stone spoke for several minutes with Robertson; pressed initial surprise that he hadn't heard from earlier。 There then followed a heated discussion of the President's decision not to call a Directive 7…12。
 
   〃The President doesn't trust scientists;〃 Roberts( 〃He doesn't feel fortable with them。〃
   〃It's your job to make him fortable;〃 Stone said; 〃and you haven't been doing it。〃
   〃Jeremy〃
   〃There are only two sources of contamination;〃 Stone said。 〃Piedmont; and this installation。 We're adequately protected here; but Piedmont〃
   〃Jeremy; I agree the bomb should have been dropped。〃
   〃Then work on him。 Stay on his back。 Get him 7…12 as soon as possible。 It may already be too late。〃
 
   Robertson said he would; and would call back。 Before he hung up; he said; 〃By the way; any thoughts about the Phantom?〃
 
   〃The what?〃
   〃The Phantom that crashed in Utah。〃
 
   There was a moment of confusion before the Wildfire group understood that they had missed still another important teleprinter message。
 
   〃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 munication 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 e 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 puter printout; a column of figures written on green paper:
 
   MASS SPECTROMETRY DATA OUTPUT PRINT
 
   PERCENTAGE OUTPUT SAMPLE 1 … BLACK OBJECT UNIDENTIFIED ORIGIN
 
   'Diagram of chemistry of the rock from H to Br'
 
   ALL HEAVIER METALS SHOW ZERO CONTENT
 
   SAMPLE 2 … GREEN OBJECT UNIDENTIFIED ORIGIN
 
   'Diagram of chemistry of green object'
   
   ALL HEAVIER METALS SHOW ZERO CONTENT
 
   END PRINT
 
   END PROGRAM
 
   …STOP…
 
   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 posed 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:  
 
   AMINO ACID ANALYSIS 
 
   'graphic of amino acid analysis all zeroes'
 
   TOTAL AMINO ACID CONTENT
 
   00。00 00。00
 
   END PRINT 
 
   END PROGRAM
 
   … STOP …
 
   〃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 plete 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。
 
   This was a delicate process; requiring many minutes of concentrated work。 At the end of that time; he had shaved the plastic in such a way that he had a pyramid of plastic; with the green fleck at the peak of the pyramid。
 
   He unscrewed the vise and lifted the plastic out。 He took it to the microtome; a knife with a revolving blade that cut very thin slices of plastic and imbedded green tissue。 These slices were round; they fell from the plastic block into a dish of water。 The thickness of the slice could be measured by looking the light as it reflected off the slices if the light was faint silver; the slice was too thick。 If; on the other hand; it was a rainbow of colors; then it was the right thickness; just a few molecules in depth。
 
   That was how thick they wanted a slice of tissue to be for the electron microscope。
 
   When Stone had a suitable piece of tissue; he lifted it carefully with forceps and set it onto a small round copper grid。 This in turn was inserted into a metal button。 Finally; the button was set into the electron microscope; and the microscope sealed shut。
 
   The electron microscope used by Wildfire was the BVJ model JJ…42。 It was a high…intensity model with an image resolution attachment。 In principle; the electron microscope was simple enough: it worked exactly like a light microscope; but instead of focusing light rays; it focused an electron beam。 Light is focused by lenses of curved glass。 Electrons are focused by magnetic fields。
 
   In many respects; the EM was not a great deal different from television; and in fact; the image was displayed on a television screen; a coated surface that glowed when electrons struck it。 The great advantage of the electron microscope was that it could magnify objects far more than the light microscope。 The reason for this had to do with quantum mechanics and the waveform theory of radiation。 The best simple explanation had e from the electron microscopist Sidney Polton; also a racing enthusiast。
 
   〃Assume;〃 Polton said; 〃that you have a road; with a sharp corner。 Now assume that you have two automobiles; a sports car and a large truck。 When the truck tries to go around the corner; it slips off the road; but the sports car manages it easily。 Why? The sports car is lighter; and smaller; and faster; it is better suited to tight; sharp curves。 On large; gentle curves; the automobiles will perform equally well; but on sharp curves; the sports car will do better。
 
   〃In the same way; an electron microscope will 'hold the road' better than a light microscope。 All objects are made of corners; and edges。 The electron wavelength is smaller than the quantum of light。 It cuts the corners closer; follows the road better; and outlines it more precisely。 With a light microscope like a truck you can follow only a large road。 In microscopic terms this means only a large object; with large edges and gentle curves: cells; and nuclei。 But an electron microscope can follow all the minor routes; the byroads; and can outline very small structures within the cell mito
