He detested land-prawns. They were horrible things, which, of course, wasn't their fault. More to the point, they were destructive. They got into things at camp; they would try to eat anything. They crawled into machinery, possibly finding the lubrication tasty, and caused jams. They cut into electric insulation. And they got into his bedding, and bit, or rather pinched, painfully. Nobody loved a land-prawn, not even another land-prawn.

This one dodged the thrown flint, scuttled off a few feet and turned, waving its antennae in what looked like derision. Jack reached for his hip again, then checked the motion. Pistol cartridges cost like crazy; they weren't to be wasted in fits of childish pique . Then he reflected that no cartridge fired at a target is really wasted, and that he hadn't done any shooting recently. Stooping again, he picked up another stone and tossed it a foot short and to the left of the prawn. As soon as it was out of his fingers, his hand went for the butt of the long automatic. It was out and the safety off before the flint landed; as the prawn fled, he fired from the hip. The quasi-crustacean disintegrated. He nodded pleasantly.

"Ol' man Holloway's still hitting things he shoots at."

Was a time, not so long ago, when he took his abilities for granted. Now he was getting old enough to have to verify them. He thumbed on the safety and holstered the pistol, then picked up the glove and put it on again.

Never saw so blasted many land -prawns as this summer. They'd been bad last year, but nothing like this. Even the old-timers who'd been on Zarathustra since the first colonization said so. There'd be some simple explanation, of course; somthing that would amaze him at his own obtuseness for not having seen it at once. Maybe the abnormally dry weather had something to do with it. Or increase of something they ate, or decrease of natural enemies.

He'd heard that land-prawns had no natural enemies; he questioned that. Something killed them. He'd seen crushed prawn shells, some of them close to his camp. Maybe stamped on by something with hoofs, and then picked clean by insects. He'd ask Ben Rainsford; Ben ought to know.

Half an hour later, the scanner gave him another interuption pattern. He laid it aside and took up the small vibro-hammer. This time it was a large bean, light pink in color.
