experiments； we didn't think it was a colony at all。 We thought it might be a single organism。 But obviously the single units have to be a micron or less in size； this is much too big。 Therefore it is probably a larger structure perhaps a colony； perhaps something else。〃
As they watched； the spot turned purple； and green again。 〃It's dividing now；〃 Stone said。 〃Excellent。〃
Leavitt switched on the cameras。
〃Now watch closely。〃
The spot turned purple and held the color。 It seemed to expand slightly； and for a moment； the surface broke into fragments； hexagonal in shape； like a tile floor。
〃Did you see that？〃
〃It seemed to break up。〃
〃Into six…sided figures。〃
〃I wonder；〃 Stone said； 〃whether those figures represent single units。〃
〃Or whether they are regular geometric shapes all the time； or just during division？〃
〃We'll know more；〃 Stone said； 〃after the EM。〃 He turned to Burton。 〃Have you finished your autopsies？〃
〃Yes。〃
〃Can you work the spectrometer？〃
〃I think so。〃
〃Then do that。 It's puterized； anyway。 We'll want an analysis of samples of both the rock and the green organism。〃
〃You'll get me a piece？〃
〃Yes。〃 Stone said to Leavitt： 〃Can you handle the AA analyzer？ 〃
〃Yes。〃
〃Same tests on that。〃
〃And a fractionation？〃
〃I think so；〃 Stone said。 〃But you'll have to do that by hand。〃
Leavitt nodded； Stone turned back to the isolation chamber and removed a glass dish from the light microscope。 He set it to one side； beneath a small device that looked like a miniature scaffolding。 This was the microsurgical unit。
Microsurgery was a relatively new skill in biology the ability to perform delicate operations on a single cell。 Using microsurgical techniques； it was possible to remove the nucleus from a cell； or part of the cytoplasm； as neatly and cleanly as a surgeon performed an amputation。
The device was constructed to scale down human hand movements into fine； precise miniature motions。 A series of gears and servomechanisms carried out the reduction； the movement of a thumb was translated into a shift of a knife blade millionths of an inch。
Using a high magnification viewer； Stone began to chip away delicately at the black rock； until he had two tiny fragments。 He set them aside in separate glass dishes and proceeded to scrape away two small fragments from the green area。
Immediately； the green turned purple； and expanded。
〃It doesn't like you；〃 Leavitt said； and laughed。
Stone frowned。 〃Interesting。 Do you suppose that's a nonspecific growth response； or a trophic response to injury and irradiation？ 〃
〃I think；〃 Leavitt said； 〃that it doesn't like to be poked at。〃
〃We must investigate further；〃 Stone said。
19。 Crash
FOR ARTHUR MANCHEK； THERE WAS A CERTAIN kind of horror in the telephone conversation。 He received it at home； having just finished dinner and sat down in the living room to read the newspapers。 He hadn't seen a newspaper in the last two days； he had been so busy with the Piedmont business。
When the phone rang； he assumed that it must be for his wife； but a moment later she came in and said； 〃It's for you。 The base。〃
He had an uneasy feeling as he picked up the receiver。 〃Major Manchek speaking。〃
〃Major； this is Colonel Burns at Unit Eight。〃 Unit Eight was the processing and clearing unit of the base。 Personnel checked in and out through Unit Eight； and calls were transmitted through it。
〃Yes； Colonel？〃
〃Sir； we have you down for notification of certain contingencies。 〃 His voice was guarded； he was choosing his words carefully on the open line。 〃I'm informing you now of an RTM crash forty…two minutes ago in Big Head； Utah。〃
Manchek frowned。 Why was he being informed of a routine training…mission crash？ It was hardly his province。
〃What was it？〃
〃Phantom； Sir。 En route San Francisco to Topeka。〃
〃I see；〃 Manchek said； though he did not see at all。
〃Sir； Goddard wanted you to be informed in this instance so that you could join the post team。〃
〃Goddard？ Why Goddard？〃 For a moment； as he sat there in the living room； staring at the newspaper headline absently NEW BERLIN CRISIS FFARED he thought that the colonel meant Lewis Goddard； chief of the codes section of Vandenberg。 Then he realized he meant Goddard Spaceflight Center； outside Washington。 Among other things； Goddard acted as collating center for certain special projects that fell between the province of Houston and the governmental agencies in Washington。
〃Sir；〃 Colonel Burns said； 〃the Phantom drifted off its flight plan forty minutes out of San Francisco and passed through Area WF。〃
Manchek felt himself slowing down。 A kind of sleepiness came over him。 〃Area WF？〃
〃That is correct； Sir。
〃When？〃
〃Twenty minutes before the crash。〃
〃At what altitude？〃
〃Twenty…three thousand feet； Sir。〃
〃When does the post team leave？〃
〃Half an hour； Sir； from the base。〃
〃All right；〃 Manchek said。 〃I'll be there。〃
He hung up and stared at the phone lazily。 He felt tired； he wished he could go to bed。 Area WF was the designation for the cordoned…off radius around Piedmont； Arizona。
They should have dropped the bomb； he thought。 They should have dropped it two days ago。
At the time of the decision to delay Directive 7…12； Manchek had been uneasy。 But officially he could not express an opinion； and he had waited in vain for the Wildfire team； now located in the underground laboratory； to plain to Washington。 He knew Wildfire had been notified； he had seen the cable that went to all security units； it was quite explicit。
Yet for some reason Wildfire had not plained。 Indeed； they had paid no attention to it whatever。
Very odd。
And now there was a crash。 He lit his pipe and sucked on it； considering the possibilities。 Overwhelming was the likelihood that some green trainee had daydreamed； gone off his flight plan； panicked； and lost control of the plane。 It had happened before； hundreds of times。 The post team； a group of specialists who went out to the site of the wreckage to investigate all crashes； usually returned a verdict of 〃Agnogenic Systems Failure。〃 It was military doubletalk for crash of unknown cause； it did not distinguish between mechanical failure and pilot failure； but it was known that most systems failures were pilot failures。 A man could not afford to daydream when he was running a plex machine at two thousand miles an hour。 The proof lay in the statistics： though only 9 per cent of flights occurred after the pilot had taken a leave or weekend pass； these flights accounted for 27 per cent of casualties。
Manchek's pipe went out。 He stood； dropping the newspaper； and went into the kitchen to tell his wife he was leaving。
***
〃This is movie country；〃 somebody said； looking at the sandstone cliffs； the brilliant reddish hues； against the deepening blue of the sky。 And it was true； many movies had been filmed in this area of Utah。 But Manchek could not think of movies now。 As he sat in the back of the limousine moving away from the Utah airport； he considered what he had been told。
During the flight from Vandenberg to southern Utah； the post team had heard transcripts of the flight transmission between the Phantom and Topeka Central。 For the most part it was dull； except for the final moments before the pilot crashed。
The pilot had said： 〃Something is wrong。〃
And then； a moment later； 〃My rubber air hose is dissolving。 It must be the vibration。 It's just disintegrating to dust。〃
Perhaps ten seconds after that； a weak； fading voice said； 〃Everything made of rubber in the cockpit is dissolving。〃
There were no further transmissions。
Manchek kept hearing that brief munication； in his mind； over and over。 Each time； it sounded more bizarre and terrifying。
He looked out the window at the cliffs。 The sun was setting now； and only the tops of the cliffs were lighted by fading reddish sunlight； the valleys lay in darkness。 He looked ahead at the other limousine； raising a small dust cloud as it carried the rest of the team to the crash site。
〃I used to love westerns；〃 somebody said。 〃They were all shot out here。 Beautiful country。〃
Manchek frowned。 It was astonishing to him how people could spend so much time on irrelevancies。 Or perhaps it was just denial； the unwillingness to face reality。
The reality was cold enough： the Phantom had strayed into Area WF； going quite deep for a matter of six minutes before the pilot realized the error and pulled north again。 However； once in WF； the plane had begun to lose stability。 And it had finally crashed。
He said； 〃Has Wildfire been informed？〃
A member of the group； a psychiatrist with a crew cut all post teams had at least one psychiatrist said； 〃You mean the germ people？〃
〃Yes。〃
〃They've been told；〃 somebody else said。 〃It went out on the scrambler an hour ago。〃
Then； thought Manchek； there would certainly be a
