rible 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 oldtimers who'd been on Zarathustra
since the first colonization said so. There'd be some simple explanation,
of course; something 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 interruption pattern. He
laid it aside and took up the small vibrohammer. This time it was a large
bean, light pink in color, He separated it from its matrix of flint and
rubbed it, and instantly it began glowing.

"Ahhh! This is something like it, now!"

He rubbed ha
