The Smoke Ring

The CARM’s bow was moored in a dock of wooden beams. Double doors led into a hut with cradles for passengers, moorings for cargo, and a broad transparent window. The window looked forth on nothing but bark.

Ventral to the window was a gray sheet of glass and a row of colored buttons.

Jeffer went forward. A touch of a blue button lit the gray glass panel. Blue governed what moved the CARM: the motors, the two flavors of fuel supply, the water tank, fuel flow. Jeffer read the blue script:

H2: 0,518

O2: 0,360

H2O: 0,001

POWER: 8,872

The batteries danced with energy. Why not? The CARM wasn’t using power. Nobody in Citizens Tree had bothered to fill the water tank in seven years; so power wasn’t needed to split water into hydrogen and oxygen.

The water tank was virtually dry.

And he could get something done while he waited for Lawri’s pond. Jeffer touched the blue button (the panel went blank) and the yellow (there appeared a line diagram of the CARM’s bow, the hut section). He touched a yellow dot in the image, and turned his fingertip. Then he moved aft.

The residual goop in pond water stayed in the tank after the pure water was gone. Jeffer’s finger motions had (magically, scientifically) caused a spigot in the aft wall to ooze brown mud. He cupped the globule in his hands. He tossed it at the airlock, and most of it got through. Another globule formed, and he sent it after the first. He wiped his hands on his tunic. The mud flow had stopped.

Next he pulled several loops of hose from cargo hooks.

He rotated one end onto the spigot, then tossed the coil through the twin doors. Done! When Lawri’s blob of pond arrived, she would find the CARM ready to be fueled.

Jeffer returned to the controls. He had a surprise for his wife.

Two sleeps ago, while the rest of the tribe was roasting waterbirds from the pond, Lawri had held one of the creatures up for his perusal. “Have you ever really looked at these?”

Jeffer had seen waterbirds before…but he’d kept his mouth shut, and looked.

There were no feathers. The modified trilateral symmetry common to Smoke Ring life expressed itself in two wings and a tailfin, all in smooth membrane on collapsible ribs. The wings could be held half collapsed for motion within the denser medium of water. Only one of the three eyes looked like a normal bird’s eye. The others were big and bulbous, with large pupils and thick lids. The bodies were slippery-smooth.

“I’ve eaten them, but…you’re right. I’ve seen everything from mobies to triunes to flashers to drillbits, and they don’t look like this. Earthlife doesn’t either. Do you think it’s so they can move through water?”

“I’ve tried looking them up in the cassettes,” Lawri had said. “I tried bird. I tried water and pond. There’s nothing.”

Jeffer’s next sleep had ended with a dream fading in his mind, leaving a single phrase: “…even the fish can fly.”

He’d had to wait until now to try it.

He tapped yellow (the display vanished), then white (and got a tiny white rectangle at the dorsal-port comer).

White read the cassettes; white summoned Voice. “Prikazyvat Voice,” he said.

The voice of the CARM was a throaty bass, as deep as Mark the dwarf’s voice. “Ready, Jeffer the Scientist.”

“Prikazyvat Read Fish. Read it aloud.”

The cassette was one that Jeffer had stolen from London Tree, but it was no different from Qui

FISH

IF THE BIRDS WITHIN THE SMOKE RING RESEMBLE FISH — LEGLESS, DESIGNED TO MOVE THROUGH AIR WEIGHTLESSLY, AS A FISH MOVES THROUGH WATER —THEN THE FISH THAT LIVE WITHIN THE PONDS RESEMBLEBIRDS.

EVERY FISH WE HAVE EXAMINED BREATHES AIR. THEY ARE NOT MAMMALS, BUT LUNGFISH. THE SINGLE CLASS OF EXCEPTIONS, GILLFISH, ARE DISCUSSED ELSEWHERE.

SOME CAN EXTRUDE A TUBE TO THE POND’S SURFACE.

A FEW CAN EXPAND THE SIZE OF THEIR FINS VIA MEMBRANES, TO MAKE THEM SERVE AS WINGS. ONE FORM, CORE FISH, INFLATES ITSELF WITH AIR, DIVES TO THE CENTER OF A POND, AND EXPELS A BUBBLE. IT CAN STAY SUBMERGED FOR UP TO A DAY — SEVERAL SMOKE RING DAYS — REBREATHING ITS AIR BUBBLE, MAKING FORAYS TO HUNT, AND THEN RETURNING.

THE WHALE-SIZED MOBY USES ITS POND AS A LAIR FROM WHICH IT BURSTS TO SWEEP THROUGH PASSING CLOUDS OF INSECTS. MOB VIS A COMPROMISE FORM, AND THERE ARE OTHERS.

CLEARLY EVEN THE LARGEST PONDS CAN BREAK UP OR EVAPORATE OR BE TORN APART BY STORM. EVERY CREATURE THAT LIVES IN A POND MUST BE PREPARED TO MIGRATE TO ANOTHER: TO BEHAVE LIKE A BIRD. EVEN GILLFISH—

“Prikazyvat Stop,” Jeffer said. This memory that had surfaced from his adolescent training under Qui

Back to work. He tapped white, then green, then each of the five green rectangles now onscreen. Within the great window that faced the bark, five smaller windows appeared, looking starboard, port, dorsal, ventral, and aft. The ventral view had a blur and a flicker to it. The rest were clear, like the window itself.

The aft view looked along the line that led west to the pond. Citizens were returning to the tree. Behind them a bud of pond was already drifting toward the tree, with the harebrain net showing as a shadow within. Lawri’s crazy idea was working.

They swarmed back along the cable toward the midpoint of Citizens Tree. Gavving and Minya and Anthon hung back, counting heads to be sure that all children were accounted for. A girl lost her grip and drifted; she was chortling and trying to swim through the air when Anthon scooped her up.

As children arrived, Clave herded the smaller ones, with some difficulty, into a rectangular frame with a slatted floor: the lift cage. He stopped when twelve children were inside. Leave room for a couple of adults.

The rest clung to the rough bark or floated like balloons on their tethers. There were wrestling matches. Eightyear-old Arth was getting good at using the recoil of his opponent’s line. He was Clave’s youngest, and just begi

Debby had arrived first. Clave could see her a hundred meters out along the bark, climbing toward the CARM.

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.
