'Check. But to get back to Joan. She's done some almost unbelievable work and we think she'll do. You know what we're after, of course.'

'All I'm afraid of is that you haven't looked far enough,' the woman said, shaking her head dubiously. 'You know, though, what an appalling job it was bound to be. I'll do whatever I can.'

She did not state the problem, either. They all knew, too well, what it was. As matters then stood, the life of one man— Neal Cloud—was all that stood between Civilization and loose atomic vortices; and it was starkly unthinkable that the Galactic Patrol would leave, for a second longer than was absolutely necessary, that situation unremedied.

'I see.' Cloud broke the short silence. 'Assuming that you haven't been sitting still doing nothing while I've been gone, brief me.'

'Smart boy!' Strong applauded. 'The first thing Joan did was to figure out that a nine-second prediction was out of the question for any computer, digital or analogue, possible to build with today's knowledge. Asked us what we could do to cut the time and how far we could cut it. With your little bombing flitter you have to have about nine seconds because you have to build up your speed to the required initial velocity of the bomb. That could be done away with, of course, by firing the bomb out of a Q-gun or something ..."

'But you'd have to have a special ship, much bigger than a flitter!' Cloud protested. 'And special guns ... and the special pointers for those guns—or for the ship, if the guns were fixed-aligned—would be veree unsimple, believe me!'

'How right you are, Buster! Other things, too, that you haven't thought of yet, such as automatic compensation for air conditions and so on. Very much worth while, however, and all done—we've had a lot of people on this project. But to cut this short, the necessary ship turned out to be a scout cruiser;

the minimum safe distance—assuming worst possible conditions and heaviest possible screening—is thirty two hundred meters . . .'

'Wait a minute!' Cloud broke in. 'I've worked closer than that!'

'You got badly burned once, too, remember; and, according to the medics, you've been taking some damage since. You won't from here on. But to resume; since the muzzle velocity we can use is limited, by the danger of prematuring on impact, to nine hundred sixteen meters per second, the time from circuit closing to detonation is something over three and a half seconds—how much over depending on atmospheric conditions. That's absolutely the best we can do, so we gave Joan a minimum of three point six seconds of prediction to shoot at with her mechanical brains. She isn't quite there yet, but she's far enough along so that she has to work with you, on actual blasting, the rest of the way.'

'Why?' Cloud argued. 'If she stayed on the high side there'd be no danger of scattering; only of intensification, which wouldn't do any harm out in the badlands.
