been young then, with the passenger compartment in the shell just big enough,
in a squeeze, for two. And he had squeezed more than one girl in it, he had,
until he had found Emily and grown up a bit. As advertised, the Tortoise had
grown too, maturing from the sports car stage to coupe. Eventually, timed by
gengineers like Emily to match a family's growth, it would gain the capacity
of a station wagon.
The Tortoise didn't look like a tortoise. Its chief ancestor had been a
lean, low terrapin. The gengineers had given it size and speed, and a cavity
beneath the shell. The General Bodies shops had fitted a windshield, side
windows, and doors, installed plush seats, added headlights and taillights,
and wired the controls into the Tortoise's nervous system. At periodic
checkups, they added new fittings and enlarged or refitted the old to keep
pace with the creature's growth.
Roachsters, half cockroach and half lobster; Hoppers, derived from
grasshoppers; and other Buggies could keep pace with a family's needs just as
well. But Nick preferred the more classic lines of the Tortoise. Its shape
reminded him of the gas-burners his parents had driven when he had been a
child, when the Machine Age had still been vigorous. The oil that had made
that Age possible had been on the verge of exhaustion, and most liquid fuels
were being produced--expensively--from coal. But people had not yet recognized
that new forms of technology were essential if civilization were to continue,
nor that the replacement technology was already taking shape. The Biological
Revolution had by then been fermenting in the world's laboratories for
decades, and the gengineers had been on the verge of long-sought success.
As Nick and Andy left the house, the Tortoise's barrellike head turned
toward them. The legs on the side facing the house flexed, Nick stepped onto
the offered lip of shell, resembling an old-time running board, and opened the
door. Andy scooted across the bucket seats to let his father take his position
behind the tiller.
Even before the door clicked into its frame, the Tortoise's knees were
rising and falling, pistonlike, in Nick's peripheral vision. He steered it
onto the greenway that had long since replaced paved streets in his suburb,
guided it toward the expressway on-ramp, and accelerated. The Tortoise's knees
became a blur, its breathing an audible gale of wind.
The expressway itself was still paved. The Public Works Department kept
promising to have it grassed, for almost all vehicles were now bioforms, or
genimals. But public money was as short as ever, and the Biological Revolution
was still new. Many residential neighborhoods, unlike Nick's, also still had
paved streets. Only a few neighborhoods had yet gone to modern bioform houses,
gengineered from pumpkins, squash, beanstalks, eggplants, and even more exotic
stock.
Air transportation was somewhat more advanced. As Nick and Andy neared the
airport, they passed a zone of bedraggled hangars and paved runways.
Airplanes--Comanches, Beechcrafts, Boeings--stood about in varying states of
dishabille. A few showed the faded, painted-over logos of major airlines. Most
wore nothing but their serial numbers.
"What's that, Daddy? Jets?" To him, the gengineered birds were the normal
technology. These were strange variants, stiff and featherless, emblems of a
realm set askew from the world he knew, but oddly reminiscent of it.
"Obsolete junkers, Andy." The traffic had been light, they would be there
in plenty of time, and Nick had relaxed. He spared a glance for the display
beside the expressway. "Real airplanes. They used to carry people. Now it's
