World Of Ptavvs   ::   Нивен Ларри

Before he was old enough to help, he used to sit beneath the guardian sunflowers and watch the trees go into the stripping plant. They would go in looking like any other mpul tree: perfectly straight, with the giant green flower at the top, and the dark blue stalk ending in a tapering tap root. In the stripping plant the flower and the soft bark and the tap root would be removed. The logs would come out shining in the sun, with nothing left but the solid fuel rocket core and the thin iron-crystal skin beneath the bark. Then the logs would be shipped to all the nearby civilized worlds, in ships which lifted on other stage tree logs.

But first there was the testing. A log was selected at random and fitted into the testing block. Grandfather and Dad would be standing by, each looking like he had sucked a sour gnal. They watched with single-minded concentration as the log was fired, ready to disapprove a whole crop at the slightest sign of misfire. Kzanol used to try to imitate their expressions. The little tnuctip technicians would be running around setting instruments and looking harried and important. They seemed too small to be intelligent animals, but they were. Their quaint biological science had mutated the stage trees out of worthless mpul trees. They had created the sunflowers which guarded the house: a hedge of twelve-foot trunks, each bearing a flexible silver mirror to focus sunlight on the green photosynthetic node, or to shift that focus onto an attacking enemy. Tnuctipun had built the gigantic, mindless yeast-eating whitefoods which fed the family and the carnivorous tnuctipun themselves. They had been given more freedom than any other slave race, because they had proven the worth of their freethinking brains.

A tnuctip would set off the log. The flame would shoot out over the valley, blue-white and very straight, darkening at the end to red smoke, while instruments measured the log's precise thrust and Grandfather smiled in satisfaction. The flame shook the world with its sound, so that little Kzanol used to fear that the thrust was in-creasing the planet's spin…

Kzanol/Greenberg reached to knock the ash off his last cigarette and saw his second-to-last burning in the ash tray, two-thirds smoked. He hadn't done that since high school! He cursed a Thrintun curse and almost strangled on it; his throat positively wasn't built for overtalk.

He wasn't gaining anything with his reminiscing, either.

Wherever in the universe he was, he still had to reach a spaceport. He needed the amplifier.
