"What happened?"

"Well, you wouldn't believe it. You have to understand these people's astrology. You know the little moon these people have—Felda, they call it—it's only a tiny thing, really only a few hundred yards wide. Well, when the Mapping Command first came by here they set down on that Moon and set up a listening post before landing, you know, the way they always do, to size up the situation through telescopes, radio, all that. Mostly they just orbit but this time they landed. God knows why. And took off again, naturally, throwing in the star drive. So today the eclipse comes off all right, but it comes off late."

He could not help smiling.

"You see what happened. A star drive is a hell of a force. It altered the orbit of the moon. Not enough to make any real difference, just a few hours a year, only minutes a day, but boy, you want to hear these people howl. And I guess you can see their point. Every movement that damn moon makes is important to them, they know where it should be to the inch. And now not only is it slightly off course, but so is every ephemeris printed on Mert. And they have them printed up, I understand, for the next thousand years. Which runs into money. We offered to pay, of course, but paying isn't going to help. It seems we've also messed up interpretations, predictions, the whole doggone philosophy. Oh it's a real ding dong. But contract? Not in a million years."

Travis sighed. That seemed to put the cap on it, all right. After all, when you start pushing people's moons around, where will it end? He brooded, his appetite gone. But he made a last effort.

"Did you discover anything at all we could use?"

"Nope. Not a thing. I finally figured the only thing to do was work on the astrology end of it, you know, maybe we could argue about interpretations. These people love to argue about interpretations. But no soap. It's too complicated. To learn enough even to argue would take a couple of years. And besides Unico is here, and also Randall, and they all have the same idea. Anyway, I don't think it would work. The eclipse is too definite. You can't argue the eclipse."

"Well," Travis said with approval, "you were on the right track. You did what you could. At least we got something out of the deal." He indicated Lappy, who was at that moment fervidly examining the interior of the viewscreen.

Trippe nodded, but his eyes were on Navel.

"By jing," he said suddenly, "your luck holds good, no matter what. I never saw the beat of it—"
