第一盏回应的灯，是他们自己的。
The first answering light was their own.
Clay 看见薄雾里闪了两下，心跳得很快，手已搭上遮板。岚却按住了他的手腕，让他等。
Clay saw two flashes in the mist. His heart raced, his hand already on the shutter. Lan caught his wrist and made him wait.
光又闪了两下，间隔与他刚才做的一模一样。
Two more flashes came, at precisely his own interval.
“那边有湿玻璃。”她说。
“Wet glass over there,” she said.
值班员移开角落一块防风板，亮点随即消失。谁都没笑。等了几天的回应近得只隔一面栏杆，叫人一时不知道该把眼睛放在哪里。
An attendant shifted a windbreak panel, and the bright point vanished. Nobody laughed. The answer awaited for days had been only a railing away. For a moment, they did not know where to look.
岚将那一行划去，在旁边写“自反”。她没撕掉纸。
Lan crossed out the entry and wrote SELF-REFLECTION beside it. She kept the sheet.
外廊上撑了帆布。天气线从染坊拆下的末端接到这里，另一端仍连着山顶那台不肯挪位的接收机。修线工沿墙把线固定好，最后一段用干布包着，放进倒扣的碗下。Clay 听见报时女声透过杂音断断续续出来，像有人站在一条很长的走廊尽头。
Canvas sheltered the outer corridor. The weather wire’s end had moved here from the dye works; the other end still reached the hilltop receiver that would not be moved. A repairer secured it along the wall, wrapped the final section in dry cloth, and tucked it beneath an overturned bowl. The woman’s time report emerged intermittently through static, like a voice at a long corridor’s end.
西岸棚的独立机芯也被送上来，固定在木盒里。它有自己的走时，不随主塔校正。伊沃在盒盖写了不要拧的字，下面又补一遍：尤其是嫌它慢的人。
The west-shore clockwork had arrived too, secured in a wooden box. It kept its own time without following tower corrections. Ivo had written DO NOT ADJUST on the lid, then added: Especially anyone who thinks it’s slow.
Clay 不禁笑了一下。
Clay smiled.
他将船长的旧图压到灯底下。纸上的两道斜线，现在一条落在暗礁外，一条几乎指进他们身后的山。过去几天镇上的灯仍在尽力照亮每一扇窗，从海上看，却像一个把胳膊缠在一起的人。
He weighted the captain’s old sketch beneath the lamp. Of its two slanting lines, one now fell beyond the reef; the other nearly pointed into the hill behind them. The town lights still tried to illuminate every window, but from the sea resembled someone with tangled arms.
“他会在哪儿？”Clay 问。
“Where will he be?” Clay asked.
“原先等候区的外侧。”岚说，“如果回信收到了。”
“Outside the original waiting area,” Lan said. “If he received the reply.”
“如果没收到？”
“If he didn’t?”
她摇头，示意先看。
She shook her head, signaling him to watch first.
他们用最普通的灯，朝固定方向发送短讯。灯罩放下，提起，再放下。Clay 当年对夜航船做过无数次相似的动作；如今每次停顿，肩膀都忍不住往前倾，仿佛能多借出一点身体，把光送远些。
They sent brief messages in a fixed direction with ordinary lamps: lower the cover, lift, lower again. Clay had made such movements countless times for night vessels. Now he leaned forward at each pause, as if lending a little more of his body could carry the light farther.
岚让他坐着发。
Lan told him to sit.
“你站得越前面，方向越不准。”
“The farther you lean, the worse the direction.”
他拉来一张矮凳，不再用身体挡风。
He fetched a low stool and stopped using his body as a windbreak.
第一轮没有回应。第二轮仍然没有。Miso 趴在他的靴子旁睡着，时不时被遮板声惊醒，睁一只眼，确认没有食物，又闭上。
No reply to the first round. None to the second. Miso slept against his boots, occasionally opening one eye at the shutter’s noise, checking for food, then closing it.
外面过了半小时，镇上的钟却比这边多走了一点。变化不大，放到一页纸上，就像两个人并肩走路时肩膀渐渐错开。
Half an hour passed outside; the town clocks gained a little more against theirs. A small difference, but on paper like two people walking together and slowly slipping out of step.
岚将新的偏差记在十一分钟下面。那个数已经不能再直接拿来用。
Lan wrote the new discrepancy beneath eleven minutes. That number could no longer be used directly.
“明天不听镇钟。”她说。
“Tomorrow we don’t follow the town clock,” she said.
值班员点头，又问：“如果外面报星期三，我们这儿是星期四，写哪一天？”
The attendant nodded, then asked, “If outside says Wednesday and here it’s Thursday, which date do we write?”
岚把两行日期都写出来，在中间画同一根竖线。
Lan wrote both dates and drew one vertical line between them.
“行动用外海报时，加这只机芯走过的时间。镇历保留。别为了把日子改对，先把钟拨乱。”
“For action, outside time plus the elapsed time on this clockwork. Keep the town date too. Don’t scramble the clocks trying to fix the calendar first.”
Clay 想起自己下船时，觉得岛上的人连星期几都弄错了。他没想到那一天的差距会变成一条必须共同走过的窄缝。
Clay remembered disembarking and thinking the islanders could not even get the weekday right. He had not imagined that missing day becoming a narrow gap they must cross together.
风把帆布掀起，太阳终于落到云层下方。不是日落，离日落还远，可云压得低，光只能从很窄的地方钻进来。
Wind lifted the canvas. The sun finally slipped below the cloud, nowhere near sunset, but the low cloud allowed light through only a narrow opening.
礁外有一个白点亮了一下。
A white point flashed beyond the reef.
它没有按他们的间隔闪。停住以后，白点移到了偏左的位置，再闪三下。
It did not follow their intervals. After pausing, it shifted left and flashed three times.
岚站了起来。
Lan stood.
Clay 没有问。他把自己的灯连遮三次，发出一个随手选的数字，又等。
Clay asked nothing. He covered his lamp three times, sent an arbitrarily chosen number, and waited.
远处先报了那个数字，再报另一个。
The distant light returned that number, then another.
不是先前留在光里的某一段动作。有人看见他们了，正在另外作答。
No old action preserved in light. Someone had seen them and was answering afresh.
Clay 想说话，喉咙里却一时没有声音。他低头找笔，发现笔就夹在手指间。
Clay tried to speak, but no sound came. He looked for his pen and found it already between his fingers.
回应来自渡轮。
The reply came from the ferry.
船长已经收到西涌的回信。原先十一名旅客都安全送回外港，船补充了水和食物，四名船员轮班在外侧等候。镇里寄出的几封家信也到了，有人要捎回回答，纸暂时留在船上。
The captain had received their western-swell letter. All eleven passengers had reached the outer harbor safely. The ferry had replenished water and food. Four crew waited outside in shifts. Several family letters had arrived too; replies awaited aboard.
一行行短讯传得很慢。说清原来那些人都已安顿，要比在餐桌旁讲完一件小事费力得多。Clay 却愿意等每一个停顿。
Each line traveled slowly. Explaining that everyone was settled took far more effort than telling a small story over a table. Clay was willing to wait through every pause.
岚将消息抄给值班员，让他派人送去学校，特别指明要告诉穿雨衣的女人和奥伦。她继续接收报时，没有让好消息挤掉要做的事。
Lan copied the news for an attendant to send to school, specifically naming the raincoat woman and Oren. She continued receiving time signals, letting good news displace no necessary work.
船长在外海看到三个不稳定的镇灯。要求他们将新使用的普通灯连续遮住一次长的，免得认错。
The captain could see three unstable town lights. He requested one long closure of their new ordinary lamp to identify it.
Clay 照做。
Clay complied.
外面的白点回了一个清楚的确认。
The white point returned a clear confirmation.
接下来，岚让船长在外侧两个已知航标之间换位置。船不靠近断联边缘，只沿安全水面走。她和 Clay 轮流记光，另一名值班员按机芯记时。天气里的潮汐报告、上午测得的水位和船侧看到的方向，第一次由活着的人在同一刻互相对照。
Next, Lan had the captain move between two known navigation markers outside. The ferry stayed in safe water, away from the disconnected edge. She and Clay alternated recording the light while another attendant timed by the clockwork. Tide reports, that morning’s water measurements, and directions seen aboard were compared at the same moment by living people for the first time.
太阳又被遮住。白点一度消失，岚停笔，等它回来才接着记，没有把缺的那段补成漂亮的线。
Cloud hid the sun again. The white point disappeared briefly. Lan stopped writing and waited for its return, leaving the gap instead of inventing a pleasing line.
他们忙到手指冰凉，终于得到一个比“黎明前后”窄得多的时段。
Their fingers grew cold, but finally they obtained a period much narrower than “around dawn.”
按外海的日期和报时，是次日五点十六分到二十四分之间。两侧方向最接近的部分更短，只能按五分钟准备。真正开始，必须等外面确认两座固定航标与镇灯成线；没有确认，纸上的时刻到了也不动。
By the outside date and time, it lay between 5:16 and 5:24 the next morning. The closest alignment would be shorter still: they must prepare for only five minutes. Actual action required confirmation from outside that the two fixed navigation marks lined up with the town light. Without that confirmation, reaching the written time meant no movement.
Clay 将这句话重复一遍，发给船长。
Clay repeated the condition and sent it to the captain.
外侧回复：懂。人不先上船。先看灯。
The reply came: Understood. No boarding first. Watch the lights first.
他看着最后那几个字，想起第七天前自己踩出警戒横木的那一步。
Clay read the final words, remembering his step beyond the warning bar before this seventh day.
“他比我稳。”他说。
“Steadier than I am,” he said.
“他载着别人。”岚答。
“He carries other people,” Lan answered.
Clay 点头。
Clay nodded.
他们把动作一项一项排出来。先撤出旧东岸和已经封闭的西段，不向它们承诺恢复；新镜先备好，全部遮住。窗口被外侧确认后，旧帘落底，下面的人亲眼报出没有漏缝；旧账由 Clay 的那一路退出。然后分处的人同时对上外侧共同的点，各自保持自己的视角，依次打开新光。
They arranged the actions individually. Clear the old east shore and sealed western section first, promising neither restoration. Prepare the new lenses with every shutter closed. After outside confirms the window, lower the old iron curtain; someone below must visually report no remaining gap. Clay’s branch releases the old debt. Then people at separate stations align to the same external point, retaining their own perspectives, and open the new light in sequence.
哪一处有人退出，就先封那一条，备用者在外面接手，不能命令原来的人继续撑。哪一段进水、认不清，就把那一段留到以后，不能拖全镇回旧方向。外信断了，或者帘没有落底，新镜不开。旧帘退到最后一道止位前还能停；越过止位，旧账开始清算，就不能再将同一个人塞回去重做。
If someone withdraws, seal that branch first; a standby takes over from outside, without ordering the original observer to endure. If a section floods or cannot be identified, leave it for later rather than dragging the town toward the old direction. If outside contact fails or the curtain fails to seat, no new lenses open. Before the final stop, the old curtain’s withdrawal can still halt. Beyond it, settlement begins; they cannot put the same person back and try again.
Clay 在那道止位旁画了一条粗线。
Clay drew a thick line beside that stop.
岚将它看了很久。
Lan studied it.
“这儿需要你自己做。”她说。
“You have to do this part yourself,” she said.
“知道。”
“I know.”
“不是别人替你喊到时候。”
“Not someone calling that it’s time for you.”
“我知道。”
“I know.”
外海又发来询问：需要哪些物资？
Another offshore question arrived: What supplies are needed?
Clay 望向岚。她忽然笑了，笑得有点茫然，像不知道该从哪里开始说。
Clay looked at Lan. She suddenly laughed, a little bewildered, unsure where to begin.
最后他们报了药、面粉、干衣物和能用的绳，随后添上轮椅需要的轴承。船长让他们不要一次报太多，船舱还得给要离开的人留位置。
They finally named medicine, flour, dry clothes, and sound rope, then added wheelchair bearings. The captain told them not to request too much at once. Cabin space was needed for departing residents.
那句话里，离开已经成了一件可以安排重量的事。
In that sentence, leaving had become something whose weight could be planned.
岚把自己的名字写到纸边，写完没有发出去。
Lan wrote her name in the margin but did not transmit it.
“你要捎信吗？”Clay 问。
“Want to send a letter?” Clay asked.
“不知道写给谁。”
“I don’t know whom to write to.”
她拿出那两枚外来的硬币，放在普通灯下。边上的字很细，光一照，显出一些他们都不认识的纹路。
She placed her two foreign coins beneath the ordinary lamp. Fine edge lettering and patterns appeared that neither recognized.
“可以先问外港有没有人认得。”Clay 说。
“We could ask if anyone in the outer harbor knows them,” Clay said.
她看着硬币，片刻后点头。
After studying them, she nodded.
他把形状和能辨认的几处花纹发出去。船长回复，眼下没人认得，愿意带拓样给其他港口问。既没有一句终于找到，也没有一个必须立即决定的承诺。
He transmitted their shape and distinguishable markings. The captain replied that nobody aboard recognized them, but he would take rubbings to ask at other ports. No declaration of discovery, no promise requiring an immediate decision.
岚将硬币收起。
Lan put them away.
“厨房里那个黄色的东西，”她忽然说，“我后来又梦见了。”
“The yellow thing in the kitchen,” she said suddenly. “I dreamed about it again.”
Clay 没追问她有没有因此记起一个完整的家。
Clay did not ask whether it had restored an entire home.
“梦里有人叫我帮忙。我转过身，什么也没有。”
“Someone called me to help. I turned, and there was nothing.”
她用手指搓了搓桌边的纸。
She rubbed the paper beside the table edge.
“我还是想找。”
“I still want to look.”
“嗯。”
“Yes.”
“我明天在外廊。做完这一班，以后也许会上船。”
“I’ll take the outer corridor tomorrow. After that shift, perhaps I’ll board someday.”
“船有位置就好。”
“As long as there’s a place.”
岚看了他一眼，露出一点笑容。这一次不是谁许诺把她送到正确的世界，只是她为自己留了一个还可以继续走的方向。
She glanced at him and smiled faintly. Nobody was promising to deliver her to the correct world. She had simply kept a direction in which she could continue.
薄暮时，伊沃的回纸送到。他根据外侧观测重新画了各处站位，删去一处低洼分支。那里离西段断口太近，明天即使亮了也不能放人。他还写明新网初起需要持续轮换，稳定后只能按实测缩短值守，不可先许诺以后人人都不用来。
At dusk, Ivo’s reply arrived. Using the outside observations, he redrew the stations and removed a low-lying branch too close to the western break. Even if it lit tomorrow, nobody could enter. He also stated that the new network would initially require continuous rotations. Once stable, only measurements could justify shorter watches. Nobody could promise in advance that attendance would someday be unnecessary.
纸角有一行字：这只钟没慢。别再说它慢了。
At the corner he wrote: This clock isn’t slow. Stop saying it is.
Clay 将它钉在木盒上。
Clay pinned it to the wooden box.
Dr. T 派来的值班长读完全部观测，问能不能带走一份。岚给了，要求保留外侧确认、失败条件与尚未证实的部分，不能只拿最像答案的半页。
Dr. T’s supervisor read all the observations and asked for a copy. Lan gave one, insisting it retain outside confirmation, failure conditions, and unproven portions, not merely the half-page resembling an answer.
他们收工前，船上最后发来一个与测量无关的问题。
Before they finished, the ferry sent one last nontechnical question.
带狗的先生还在吗？
Is the gentleman with the dog still there?
Clay 回答在。
Clay answered yes.
零钱还在。
Your change is still here.
他低下头笑了很久，笑到眼睛有点酸。Miso 被脚下的动静吵醒，抬头看他，不明白为什么两手空空也能这样高兴。
He bowed his head and laughed until his eyes stung. Miso woke at the movement, looked up, and failed to understand such happiness with empty hands.
Clay 摸了摸它的脑袋，把最后的回复发出去。
Clay stroked his head and sent the final reply.
那就先替我放好。
Keep it for me a little longer.
