There was a person at the second point, but not the same rock.
On the hundred and seventy-ninth morning, Sera sat at the permitted level observation place. Her knee had allowed the short walk. The current worker said the wind was within starting limits. An existing observing board stood before her; the other observer had gone to the separate land position.
The places were apart. No one had copied one person's sheet. That alone did not let the comparison begin. First they had to establish that both could see the same part of the rock. Sera described the black upright groove beside the removed white board's place.
The response came through the worker's agreed relay. Two dark marks overlapped from the other position. One might be the groove, the other the adjacent support's shadow. Sera wanted to describe hers louder. Volume would not separate two marks in somebody else's sight.
She explained the bend at the groove's top and its position relative to the former board. The worker compared the descriptions. The other observer still could not say which mark it was. Sera did not say that a fixed rock must therefore be the same object in both accounts.
“Couldn't we match the time first?”
“With different targets, you'd be looking at different things very precisely.”
Her ears warmed. She had learned this repeatedly over the past days. Yet arriving at her own place made her want to begin her turn quickly.
She took her hand from the board. The agreed tide-time window was passing. It felt like losing time, but fixing the wrong target would require asking what they had read all over again. She recorded that the comparison had not begun: today's same-target condition was not met.
Before the wind strengthened, the worker allowed one further view check. Sera moved her head slowly within the present angle, keeping her body inside the chair. The rail concealed the groove's bottom. She could not attach somebody else's description of what was below it to her own observation.
The screening cloth snapped once. A shadow crossed the board and deepened the rock's dark line. Sera looked at the cloth before reading the bearing scale. The worker told her to stop. She stopped. No value was read through a wind-shaken view.
The adult responsible for the cloth checked its fastening. Tio was not here. Nobody would suddenly put the resting apprentice on the end of it because his finger happened to belong to an available pair of hands. Sera did not offer her own arm either. Her task was to say what was visible from her observation place.
When the wind eased, the other position sent a new explanation. Separating the marks would require a permitted change of observing height. Today's prepared conditions did not allow that change immediately. The current worker ended the comparison.
Sera answered a beat late. She was disappointed. The worker accepted that and covered the instruments, without offering reassurance that it had not been a failure. Today she had not obtained the comparison she wanted. She could keep its size and still breathe more easily because its reason could be stated.
Before the chair moved, her knee ached. She asked to rest longer. The workers cleared the board and left the available resting place. Finished equipment need not remain spread out for her. Her eyes could still see the sea; the place for measuring it had closed.
At the level-ground chairs Nume was putting down a water container. How had it gone? They had stopped because they could not distinguish whether the observers were seeing different things.
“So the missing boat wasn't the problem.”
She did not laugh. Nume stopped joking. After waiting so long and finally using her own eyes, she felt blocked by something smaller. Which thing was smaller? Failing to see one rock together, she said.
“Pass a rock while seeing it differently from someone else aboard, and it isn't small.”
She did not hear an attempt to justify her work through sailing. Nume was describing the size of something in their own work. Today it had not been small for her either.
Yesterday, when she learned another position was possible, she had eaten dinner with the face of someone already successful. Permission to try and the comparison's result were easily heard as one answer, the captain said. She had separated them for other people, then mixed them in her own expectation.
She did not declare she would stop hoping. Tomorrow she would want to see well again. She could still go back and accurately explain what question had received which answer today.
“Enough to drink some water now?”
She drank. Nume did not arrange her next appointment. Their afternoon work meant leaving soon. Sera was sorry they could not share lunch. Every empty stretch of the sea did not belong beside her chair. Today they would eat separately.
After lunch the other observer sent a short explanation with the current worker. It distinguished the two marks as they appeared from that place. Hearing the permitted account, Sera did not begin by saying the other person had looked at the wrong rock. Neither observer could yet be declared at fault.
A support before the rock might overlap the groove from a lower view. To change the conditions, facilities and observing staff would have to check another usable height. Sera did not propose stacking chairs. A convenient eye level was not automatically a safe place.
She described the lower portion hidden by her own rail too. She would not write as if her view were perfect and only the other's failed. The worker retained both conditions. Two partially obscured eyes did not automatically fill each other's unseen parts.
Varen listened downstairs. He had met a similar sight-line problem in his early joint-network work, he began.
“I don't need an old experience to finish today's problem quickly.”
Her voice was sharper than she intended. He understood and stopped.
After a moment she explained. Hearing that somebody had already experienced it made her feel she ought to know it already too. He did not answer that feeling with another experience. Instead he asked what had made her stop today.
Two marks, a hidden lower end, moving cloth. Saying them divided her vague failure into three objects. Varen suggested they need not all be repaired by the same person. That was useful. It could help distinguish current responsibilities.
Facilities would reconsider the view; observing staff would establish target identity; she would reconsider her knee. She chose the questions she actually needed to deliver rather than making a long list. Another report would not change today's wind.
Tio came downstairs when the sun was low. Asked what she had seen, she began with what she had not. Then the bottom of the picture should stay blank, he said.
“I wasn't asking you to draw it.”
“I know. My head did it already.”
What shape was the blank? A base cut off above the rail. Her eyes had shown that too. Then the rock had not shortened, he said. The picture had. That was closer to the sentence she had needed today.
The evening message brought tomorrow's possible conditions. Another face of the existing level area might separate the groove and support. No new structure would be made. Only after a successful view check could time matching begin again.
Could the worker check the view without her participation? Yes. If her body was not comfortable in the morning, she would defer her own observation. The worker accepted that condition. Feeling she had lost one day need not take tomorrow's body in advance.
Miran saw her at dinner. Sera said they had not obtained the desired comparison. Had it moved further away again? They had not been measuring the distance of a new homeward journey. They had stopped while checking whether a land reference could be seen together.
After a silence Miran said she still wanted to know when she could go home. Sera knew. Even success today would not have given a return date. She did not evade that. Miran nodded and finished her meal first.
Nume arrived later. Work had run late. Could they eat together now? The remaining time was free. Sera did not begin the day's observation again from the first sentence. Nume first asked whether they could eat quietly.
For a while they softened bread in their food. Sera noticed it was not flattened.
“Straight from the dining room,” Nume said. “My bag never got its chance.”
This time she laughed. The day need not close between two observing points. Warm food still reached her mouth.
Returning to the lighthouse, she chose the presently open dry path. Darkness hid the groove. Its invisibility did not erase today's object. There had also been a real person at the second position. Seeing the same thing next time would require changed conditions.
Both clear stones stayed in their chests, the blue clay bell without a clapper. There had been no new sailing. Twenty residents remained at Roan; eight departures and seven limited round trips were unchanged. Today's stopped comparison belonged in neither sailing count.
At night she folded her private note. Had she written the old easy phrase TWO PEOPLE SAW IT, she would have erased it. Instead: NOT YET ABLE TO DISTINGUISH WHETHER WE SAW THE SAME PLACE. Even the paper with no line between its points told her what to do first tomorrow.
