Booce pointed to Jeffer’s selection. “That one.”
Ten klomters above the tuft, the wood of the trunk had grown to enclose a node of foreign matter. Jeffer saw Booce catch his daughter’s eye as Carlot was about to speak. She held her silence.
At the tree midpoint Jeffer nosed the CARM against the trunk. He ran the attitude jets while his crew pounded spikes into the bark to mark a rectangle the size of the CARM’s bow. The CARM drifted while they chopped out a dock with matchets.
Even on this younger tree, the bark was a meter thick.
They made life easier for themselves by chopping along cracks. The five of them lifting together could rip great mattresses of bark away from the wood beneath, then saw off sections. Booce and Carlot used the saw, then let others take over until they got the hang of it.
Booce and Carlot rejoined Jeffer in the CARM. Booce said, “They seem to be doing all right.”
“But it’s scarred,” Carlot objected.
“And how much wood will that cost us?”
She shrugged. “Five percent? And weren’t we in a hurry to get home?”
Booce was smiling. “Exactly. Jeffer, why this tree?”
“You’ll be painting a line of honey down the trunk, stet? Have a look at that scar.”
“Can you tell me what I’m supposed to find?”
“No, I can’t.”
“Jeffer the Scientist, Citizens Tree gave us shelter and a place among you. We’re grateful. I will not quarrel with any decision you make. You won’t need to test it again.”
Jeffer could feel his ears and cheeks burning. “If that scar isn’t more interesting than you expect, you can count on it that I won’t make a fool of myself twice. Stet?”
“Stet. I won’t raise this subject with the Chairman, ever.”
“You are kind. What’s next?”
“The honey line.”
In the cabin the roar of the main drive was like a great beast heard far away; but outside the airlock the roar was deafening. A translucent blue flame reached out from the CARM’s main rocket nostril. Warmth backwashed against the bark.
Carlot’s eyes were big with fear. Rather pulled at her arm to set her kicking toward the in tuft, and followed, with Booce following him.
They stopped where the noise had decreased somewhat. The rough bark itself absorbed sound. Booce screamed, “That noise is beyond belief! What is that damn CARM, a ship from the stars?”
“Jeffer says it rode here on the starship. My father never saw Discipline.” What Rather said would be true whoever his father was. “But he’s seen the stars. They’re real.”
“I’m afraid of it. I admit it. Look, the noise is scaring the bugs out of the bark! Let’s get to work.”
Booce used a branchwood matchet to open a hole in one of the honeypots. The interior was partitioned; the cells held red, sticky honey. Booce used the blade to paint it on the bark.
“You’ll find a few hornets still in there,” he told Rather. “They try to sting through the sack if you give them a few days to get restless, and then they die. But don’t count on it. Don’t let one get at you. Now you paint dabs a couple of meters apart. Closer, you waste honey. Farther apart, the bugs lose their way.”
Rather had thought he was a climber, but this was different. He had problems keeping up. He was almost lost among the sacks he was carrying. Booce and Carlot climbed head down; they would have left him behind if Booce had not been stopping to paint the trunk.
They took a breather when the sun was at nadir and the shadows had become confusing. The sun was passing closer to Voy as the year waned.
A day later they took a longer rest. “This is the part I like best,” Booce said. “We’re usually in too much of a hurry. This time your CARM is already pushing us home. We can take our time, do what we like!”
“Like what?”
“I’ll show you as we go.” Booce began tearing up sheets of bark greater than a man, mooring them edgewise against the bare wood. When he had them arrayed he set them alight.
The smoke tended to stay where it formed. Booce moored a four-kigram slab of shellbird meat in the cloud. They broiled smaller steaks on their matchets, closer to the fire, and ate them still hot.
“The smoked meat will keep till we’re down,” Booce said. “But there are other things on the trunk. You’ve never climbed?”
“When we were children we did a little climbing, but just on the lower trunk. We weren’t supposed to go more than a klomter up. If you fell, the foliage would catch you. Any higher, we rode the elevator.”
They slept carefully tethered in cracks in the bark.
Sometimes, for moments, the roar of the CARM could be heard above the wind. A dark cloud had formed above them and was gradually drifting down.
The bugs of the tree had found the honey.
They breakfasted on smoked bird. Then Carlot did the painting while Booce carried the food.
The sun circled them, once and again. Always they stopped when the shadows were pointing straight out.
Water was beginning to flow sluggishly in alongside their path. “Bugs like it damp,” Booce said. “The bark’s wet enough for them around the midpoint, but not lower down. You have to paint down the east side, alongside the waterfall, or they won’t come. Also the trunk blocks the wind. You don’t want the bugs blown away.”
There was fan fungus like so many pallid hands reaching from the bark. Carlot showed Rather how to tear the red fringe off before eating the white interior. It was bland, almost tasteless, but went well enough with the strongly flavored smoked meat.
With lunch came entertainment: a gust of roses on the wind. The stems were four meters long. Dark-red blossoms fragile as tissue paper pointed straight toward Voy, soaking up blue Voy-light. Rather had never seen the like.
He and Carlot watched the roses blowing east until they were out of sight.
Rather took his turn painting. Booce kept a close watch, but it seemed simple enough. A dab the size of a baby’s hand; the next dab two meters lower.
A dark cloud flowed after them down the trunk.
The wind grew stronger, though the trunk blocked most of it. The growing tide made climbing easier for Rather. The water flowed more strongly. It was cleaner than pond water, cleaner than the water that reached the basin in the commons. It tasted wonderful, and painting was hard, thirsty work.
In two days. Rather’s arm was one long cramp.
He was too tired to help with dinner. Booce managed alone. He found shelled things hiding in the bark and pulled them loose. Roasted, their white flesh made a fine meal.
Again they wedged themselves along a wide crack in the bark, with Carlot between the men. There were dangers on the trunk.
Rather’s aches kept him awake. He presently noticed Carlot’s feet stirring restlessly. “Carlot?”
He would not have spoken twice, but she answered at once. “Can’t sleep?”
“No. My father told me about climbing up a tree. When they got to the top the tree came apart.”
“That’s one reason we don’t just chop off the tuft or burn it loose. This is easier, but it also gets the bugs away from the midpoint. When the tree dies, they’re not there to eat it apart.”
“How do you get rid of the out tuft?”
“Oh, some of the bugs won’t follow the honey. They’ll be breeding while we travel. When we get close to the Clump we’ll paint another trail out.”
“Why are you awake?”
“Tide. I have trouble sleeping in tide.” But her voice trailed off raggedly. He stopped talking, and presently slept.
After breakfast Booce said, “There’s something I want to see on the west side of the trunk. Leave the gear here.”
Climbing was easy if you didn’t have to paint too. In less than a day they had half circled the trunk. Above them by a quarter klomter, the bark bulged like a wave surging across a pond. They climbed toward that.
