Viggon waved a hand to indicate he had heard enough.

"Gentlemen," he said quietly. "I've been criticized for waiting, but what one man calls study the other man calls timidity. We'll continue to wait for the final factor. Then we'll know...."


The stereo pattern in the Information Center of Commodore Ted Wilson's flagship was slowly being filled with the hazy white that indicated that these volumes had been combed carefully. As he watched, he could see how the search was progressing, and it was painfully obvious that the search was not going good at all.

The flights of spacecraft in set patterns back and forth through the stereo had covered nearly all of the truncated space cone. The random search ships were slowly cutting secondary lines through the regions already covered. There was a green sphere combing the stereo pattern now, indicating the new infrawave detector ship and its expected volume of detector coverage.

Space was filled to overflowing with the fast patter of the communications officers, using infrawave for talks between flights, and ordinary radio for talks between ships of the same flight.

Wilson had appointed Chief Communications Officer Haggerty to police the bands. Haggerty had done a fine job, removing the howling confusion and interference caused from too many calls on the same channel. But the result was still a high degree of constant call and reply and cross talk. Most of the chatter came from the infrawave detector ship, sending the scout craft flitting hither and thither on the trail of spurious responses.

It was almost impossible to grasp the extent of the operation. Only in the stereo pattern could anybody begin to follow the complex operation, and those who watched the stereo knew that their pattern was only an idealized space map of what they hoped was going on.

It was worse than combing the area of an ocean from maps that contained a neat grid of cross rules. Much worse. For the uncharted ocean is gridded with radio location finders so accurate that the position of two ships a hundred yards apart shows a hundred yards of difference in absolute position in the loran.

Some day in the distant future space would be solid-gridded with infrawave navigation signals. Then the space coordinates of any spacecraft could be found to a fine degree of precision. But now all that Wilson and his nav-techs could do was to keep sighting the fixed stars, and from them compute their position.
