At first glance, they were as different as possible; they were at opposite ends of the spectrum, sharing nothing in common.

And yet there must be something in common.

It took Hall half an hour to finish his examination of the child. At the end of that time he was forced to conclude that the infant was, to his exam, perfectly normal. Totally normal. Nothing the least bit unusual about him.

Except that, somehow, he had survived.

15. Main Control

STONE SAT WITH LEAVITT in the main control room, looking into the inner room with the capsule. Though cramped, main control was complex and expensive: it had cost $2,000,000, the most costly single room in the Wildfire installation. But it was vital to the functioning of the entire laboratory.

Main control served as the first step in scientific examination of the capsule. Its chief function was detection—the room was geared to detect and isolate microorganisms. According to the Life Analysis Protocol, there were three main steps in the Wildfire program: detection, characterization, and control. First the organism had to be found. Then it had to be studied and understood. Only then could ways be sought to control it.

Main control was set up to find the organism.

Leavitt and Stone sat side by side in front of the banks of controls and dials. Stone operated the mechanical hands, while Leavitt manipulated the microscopic apparatus. Naturally it was impossible to enter the room with the capsule and examine it directly. Robot-controlled microscopes, with viewing screens in the control room, would accomplish this for them.

An early question had been whether to utilize television or some kind of direct visual linkup. Television was cheaper and more easily set up; TV image-intensifiers were already in use for electron microscopes, X-ray machines, and other devices. However, the Wildfire group finally decided that a TV screen was too imprecise for their needs; even a double-scan camera, which transmitted twice as many lines as the usual TV and gave better image resolution, would be insufficient. In the end, the group chose a fiber optics system in which a light image was transmitted directly through a snakelike bundle of glass fibers and then displayed on the viewers. This gave a clear, sharp image.

Stone positioned the capsule and pressed the appropriate controls. A black box moved down from the ceiling and began to scan the capsule surface. The two men watched the viewer screens:

"Start with five power," Stone said. Leavitt set the controls. They watched as the viewer automatically moved around the capsule, focusing on the surface of the metal. They watched one complete scan, then shifted up to twenty-power magnification. A twenty-power scan took much longer, since the field of view was smaller. They still saw nothing on the surface: no punctures, no indentations, nothing that looked like a small growth of any kind.

"Let's go to one hundred," Stone said. Leavitt adjusted the controls and sat back. They were beginning what they knew would be a long and tedious search. Probably they would find nothing. Soon they would examine the interior of the capsule; they might find something there. Or they might not. In either case, they would take samples for analysis, plating out the scrapings and swabs onto growth media.
