The bud-pond continued to move. Lawri wore a proprietary smile. Still, Citizens Tree had better have more line next time they tried this. The pond was too close. If the tree had brushed it there would have been a flood.

The lift now held a score of children. Whoever was in the treadmill would have a problem braking that weight. It couldn't be helped. Clave looked about. Mark and Anthon looked ludicrous together. Mark short and wide, Anthon long and narrow, their heads pointing in opposite directions- He called, "Anthon, Mark. Take the children down and bring back any adult you can find. Be prepared to fight a fire."

Anthon stared in astonishment. "Fire?"

"Burning tree. It's around the other side of the trunk now. Go down and get some help. Rather- Where on Earth is Rather?"

Mark pointed outward. "I didn't know any reason to stop them," he said defensively. "They won't fit in the lift this trip-"

Clave cursed silently as he watched Rather and Jill clawing their way out along the bark. There was no tide to hurt them here. If they slipped, someone would go get them. But he could have used their help.

Jeffer couldn't guess how long it took him to realize that the background had changed. Behind the five camera views superimposed upon it, the window no longer showed bark a few ce'meters distant. It showed a huge face, strong, with massive bones: the brutal face of a dwarf.

Discipline

from the Citizens Tree cassettes, year 6 SM:

FIRE

MAKING A COOKP1RE IN FREE-FALL IS AN EXCESSIVELY INTERESTING EXPERIENCE IF WHAT YOU REALLY WANTED WAS DINNER. IT'S TAKEN ME EIGHT STATE YEARS TO PERFECT MY TECHNIQUE.

THE FIRST LESSON IS THAT A FLAME DOESN'T RISE IN FREE-FALL. I LEARNED THAT WITH A CANDLE, WHEN I WAS A CADET DREAMING OF STRANGE WORLDS. IF THERE'S NO WIND (TURN OFF THE AIR FEED), THE CANDLE FLAME SEEMS TO GO OUT.

BUT IT ISN'T OUT YET. THERE'S WAX VAPOR, AND THERE'S THE AIR AROUND IT, AND AT THE INTERFACE IS AN ENVELOPE OF PLASMA WHERE GAS AND OXYGEN INTERACT. IT CAN STAY HOT FOR MINUTES. COMBUSTION CONTINUES AT TfiE INTERFACE. WAVE THE CANDLE AND POP\ THE FLAME IS BACK.

IN THE CASE OF A COOKFIRE, THE WOOD CONTINUES TO CHAR. WAIT AN HOUR, THEN BLOW ON THE COALS WITH A BELLOWS. THE FIRE JUMPS TO LIFE AND THERE WENT YOUR EYEBROWS.

-DENNIS QUINN, CAPTAIN

DISCIPLINE HAD BEEN DETERIORATING.

Cameras outside the hull showed rainbow-hued scars from matter that had penetrated the electromagnetic ramscoop while Discipline was in flight. They also showed newer micrometeorite pocks. Sharls could ward off anything big enough to see coming, by turning on those magnetic shields for a few seconds, but they ate power in great gulps.

One day he might regret even the little power he used to maintain the gardens and the cats.
