Dr. T 在给一把椅子换腿。
Dr. T was replacing a chair leg.
食堂已经关了两盏灯，剩下一盏放在地上。他跪在灯边，膝下垫着折起的外衣，把新削出的木楔敲进裂口。白天装过木夹的那只衣兜还破着，线头垂在地上。
Two dining-hall lamps were off; the last stood on the floor. Kneeling beside it on his folded coat, he hammered a freshly cut wedge into a crack. The pocket that had held pegs remained torn, loose thread trailing on the floor.
Clay 进门时，他没抬头。
He did not look up when Clay entered.
“记录我看了。”
“I read the records.”
Clay 将带来的文件放到桌上。鸭嘴兽先生跟在后面，把同一份留在学校的编号核对过，才坐下。
Clay placed his documents on the table. Mr. Platypus followed and checked their numbers against the matching school copy before sitting.
“还有今晚的人手。”Clay 说。
“And tonight’s staffing,” Clay said.
“我也看了。”
“That too.”
Dr. T 将椅子翻过来，按了按靠背。它仍有一点摇晃。他又翻回去，继续垫那条短腿。
Dr. T turned the chair upright and pressed its back. It still wobbled. He inverted it again and continued packing the short leg.
Clay 等着。
Clay waited.
以前他们一起工作，Dr. T 不想回答的时候，总会先去修一个能够修好的东西。椅子、水壶、坏掉的门栓。那些小物件有明确的坏法，可以给他们争取几分钟，不必立即碰更大的问题。
When they worked together, Dr. T always repaired something repairable before answering a difficult question: chair, kettle, broken latch. Small objects had definite failures and bought a few minutes before larger problems.
“低街被删了。”Dr. T 说。
“You dropped the low street,” Dr. T said.
“是。”
“Yes.”
“你们也开始决定哪儿不要了。”
“You’re deciding what to abandon too.”
“我们只敢先接住这几处。低街的人已经上来了，东西还在。”
“These are the places we dare try to hold first. The low-street residents have come up. Their things remain.”
Dr. T 扶着椅背站起身。他膝盖僵了一下，手停在桌边，很久才松开。
Dr. T rose against the chair back. His knee stiffened, leaving his hand braced on the table for a long moment.
“等新镜开了，别处再掉，你会不会也说，只差一点，再多给我一个晚上？”
“When the new lenses open and somewhere else falls away, will you say you’re almost there and ask for one more night?”
Clay 看着他。
Clay watched him.
“可能会想这么说。”
“I might want to.”
“那与我有什么区别？”
“How does that differ from me?”
“所以不该再让一个人决定。”
“That’s why one person shouldn’t decide anymore.”
Dr. T 没有被这句话说服。他走到墙边，揭开主塔今晚的记录，让 Clay 看下去。
Unpersuaded, Dr. T uncovered that night’s tower record on the wall for Clay to read.
染坊已经停了大半天，旧灯仍在向更高的幅度偏。西段被切掉，负担短暂降过一次，随后又升起来。图上用红铅笔标着明早的潮位，线还没走到那里，笔尖的位置却已经接近纸边。
The dye works had been stopped for most of the day, yet the old light’s deviation grew. Cutting off the west briefly reduced the load; then it rose again. Red pencil marked the morning tide. The trace had not reached it, but the needle was already close to the paper’s edge.
“你也看见了。”Clay 说。
“You see it too,” Clay said.
Dr. T 点头。
Dr. T nodded.
“我可以再退两区。”
“I could retreat another two sectors.”
“退到哪里？”
“To where?”
“主塔和学校。”
“Tower and school.”
“多久？”
“For how long?”
他没有回答。
No answer.
走廊里传来一阵小孩咳嗽，有人端着水匆匆过去。几个人都停下，等那声音离开。
A child coughed in the corridor. Someone hurried past carrying water. They all paused until the sound moved away.
Dr. T 将修好的椅子推到桌边。Clay 坐上去，椅子很稳。这个小小的成功让他比刚进来时更难过。
Dr. T pushed the repaired chair to the table. Clay sat. It was steady. That little success saddened him more than when he arrived.
“我不是要你保证新办法一定成。”他说，“你已经知道旧办法不能保证他们过完明天。”
“I’m not asking you to guarantee the new method,” he said. “You know the old one can’t guarantee they survive tomorrow.”
“新办法把风险分给了所有人。”
“The new method distributes risk to everyone.”
“是。有些人没选它，也要受影响。”
“Yes. Even people who didn’t choose it.”
Clay 把贝娜留下的记录放到最上面。反对、缺口、未证实的部分，都在那里。他没有说大家已经一起作了一个毫无亏欠的决定。船还靠不了，人也不能简单地走出小镇，所谓选择本来就被他们过去做过的事挤得很窄。
Clay placed Bena’s record on top: objections, gaps, unproven claims intact. He did not say they had collectively made an innocent decision. The ferry could not dock; people could not simply walk out. Their past actions had already narrowed choice severely.
“他们至少应该知道你准备退哪两区。”他接着说，“如果你要继续旧办法，也把那张图带出去。”
“They should at least know which two sectors you mean to retreat from,” he added. “If you continue the old method, take that diagram outside too.”
Dr. T 看向图旁挤在一起的床位数。
Dr. T looked at the crowded bed counts beside it.
鸭嘴兽先生将另外一个纸袋放到桌上，解开绕了三圈的细绳。里面不是新的名单，是七年来经他手的续期副本，按时间排列，最上面几张已经发黄。
Mr. Platypus put another envelope on the table and unwound three turns of cord. It held no new roster, only seven years of renewals he had handled, chronologically arranged, the first pages yellowed.
“这个也出去。”他说。
“This goes outside too,” he said.
Dr. T 翻了两页，停在一处自己的签字上。
Dr. T turned two pages and stopped at his signature.
“当时学校底下已经空了。”
“The ground beneath the school was already gone then.”
“原始记录写着。”鸭嘴兽先生说。
“The original record says so,” Mr. Platypus replied.
“如果不做，孩子们——”
“If we hadn’t acted, the children—”
“那天救了人，也写着。”
“It says people were saved that day too.”
Dr. T 的手指停住。
Dr. T’s fingers stopped.
“不用先抹掉那天，才追问后面七年。”
“We don’t have to erase that day to question the next seven years.”
屋里只剩灯芯轻微的嗡声。
Only the lamp’s faint hum remained.
Clay 看向茶水间里那座小镇模型。几天前，Dr. T 曾给他们指过模型里的路。如今西侧的几块小木片被移开了，留下原先固定它们的浅色胶痕。模型上的空缺整齐，现实里的却充满没来得及拿走的东西。
Clay looked toward the town model in the tea room. Days ago, Dr. T had pointed out its roads. Now several western wooden pieces had been removed, leaving pale glue marks. The model’s gaps were tidy; the real gaps were full of things nobody had managed to carry out.
“我记得刚有那条街的时候。”Dr. T 说。
“I remember when that street first existed,” Dr. T said.
Clay 转回头。
Clay turned back.
“你嫌我把码头画得太好，工人根本没地方放碎木料。我说等建起来再留，你把一堆刨花直接倒在桌上。”
“You said I’d drawn the harbor too beautifully. Workers had nowhere for scrap wood. I said we’d leave space once it was built. You dumped shavings on the table.”
Clay 记得。那天他们争到很晚，后来有人从模型上拿掉一间漂亮得没有用途的亭子，给真正的码头留出了空地。
Clay remembered. They argued late. Eventually someone removed a beautiful, useless pavilion from the model, clearing space for a real harbor.
“现在我还会记得那条街。”Dr. T 说，“但可能不知道你为什么在旁边。”
“I’ll still remember the street,” Dr. T said. “Perhaps not why you were beside it.”
Clay 没想到他会先说这一部分。
Clay had not expected him to mention that first.
Dr. T 摘下眼镜。他的眼圈发红，眼镜架在手里转了半圈，又停住。
Dr. T removed his spectacles. His eyes were red. The frame turned halfway in his hands, then stopped.
“我曾经以为，只要一直修着，就能慢一点失去。”
“I thought if I kept repairing, loss would come more slowly.”
“有些地方确实慢了一点。”Clay 说。
“In some places it did,” Clay said.
“可你们还是都走到这里了。”
“Yet you all ended up here.”
“我们得从这里往下走。”
“We have to go on from here.”
门外有人敲门，送来西灯最新的读数。Dr. T 接过纸，拿起笔，习惯性要写恢复某段。笔尖刚碰纸，他又停住。
A knock brought the latest western-light reading. Dr. T took it and automatically raised his pen to order a section restored. As the tip touched paper, he stopped.
那一段已经没有人住。
Nobody lived there anymore.
他把纸递给值班长，要求保持封闭，随后叫他把旁路操作柄拿来。
He returned the sheet to the supervisor, ordered the section kept closed, then requested the bypass handle.
Clay 没有立即起身。他等到那根裹着旧布的铜柄真正放在桌上，才慢慢将手从膝上松开。
Clay did not immediately rise. Only when the brass handle, wrapped in old cloth, lay on the table did his hands slowly release his knees.
Dr. T 从内袋里取出钥匙，放到旁边。
Dr. T took the key from his inner pocket and laid it beside the handle.
“钥匙给谁？”值班长问。
“Who keeps the key?” the supervisor asked.
“今晚由你和学校那边共同记。”Dr. T 看向鸭嘴兽先生，“以后再定新的保管办法。不能又落在谁一个人的口袋里。”
“Tonight you and the school record its custody together.” Dr. T looked at Mr. Platypus. “Set a new arrangement afterward. It mustn’t end up in one person’s pocket again.”
“仓房的镜？”Clay 问。
“The stored lenses?” Clay asked.
“取出来。两面都能用。一面边上有裂，不放迎风处。”
“Bring them out. Both work. One has a cracked edge. Keep it out of the wind.”
他说完，走向旁路门。没有让 Clay 跟着自己作什么承诺，也没有问明天会不会有人原谅他。
He went to the bypass door without demanding a promise from Clay or asking whether anyone would forgive him tomorrow.
门开时，锁芯涩得发响。
The stiff lock rasped as it opened.
里面比 Clay 记得的热。铜管顺着墙向上，地面一层细灰，角落放着接替镜的空架。岚拒绝的那套装置仍在那里，姓名栏空着，没有因她拒绝就被悄悄填上其他人的名字。
Inside was hotter than Clay remembered. Copper pipes climbed the wall. Fine dust covered the floor. In a corner stood the empty replacement-lens frame. The apparatus Lan had refused remained, its name field blank. Nobody had quietly entered someone else after her refusal.
Dr. T 将空架上通往主灯的短连杆卸下来，交给值班长收好。
Dr. T removed its short linkage to the main light and gave it to the supervisor.
“这条明天不接。”
“This stays disconnected tomorrow.”
他带 Clay 看真正要用的止位。横轴前半程让厚铁帘下降，最后一小段带动旧参照脱开。两者之间有一道可以停住的凹槽，不能将检查和退出混作一个动作。
He showed Clay the actual stop. The first part of the shaft’s travel lowered the thick iron curtain. The final short section disengaged the old reference. Between them was a holding notch. Inspection and release must not become one action.
Clay 把手放到柄上，试位置，没有转动。
Clay put his hand on the handle to test his position, without turning it.
Dr. T 指出哪儿最重，哪里会被旧油卡住，又将主灯里刻着 C-17 的参照框指给他看。Clay 从旧衣带出的薄铜片只是随身检修标记，编号与框上相同。他把标记收回纸袋，核过真正要退出的那一处，Dr. T 才将身体让开。
Dr. T indicated the heaviest point, where old oil might bind, and the C-17 reference frame inside the main lamp. The thin copper plate from Clay’s coat was only a portable maintenance tag with the same number. Clay returned it to its envelope and verified the actual point to release. Only then did Dr. T step aside.
随后他们到下层检视窗。值班长在旁边复述，确认清泥必须等旧帘下到临时挡位，隔住通往槽底的侧光，再由下方小口刮除。操作工具有长度限制，手不能伸进帘下。若帘不落底，全部人保持新镜关闭，止位不越。
They went below to the inspection window. The supervisor repeated the sequence: clearing sludge required the old curtain at its temporary stop and side light to the groove blocked, then scraping through the lower opening. Tools had a length limit; no hand could enter beneath the curtain. If it failed to seat, all new lenses stayed closed and the final stop remained uncrossed.
这些话并不使 Clay 心安，却让他知道明天惊慌时应该抓住什么。
The instructions did not soothe Clay, but gave him something to grasp during tomorrow’s fear.
午夜后，主塔仓房的门也开了。
After midnight, the tower storeroom opened too.
工人抬镜，奥伦借来车，缝纫机的主人拿她存下的布条包住裂边。她不愿看光孔，就坐在油灯旁给每一块遮帘缝上方便握住的宽带。贝娜嫌带子太软，亲手试了一下，随后把自己的意见收回去。
Workers carried lenses, Oren borrowed a cart, and the sewing-machine owner padded the cracked edge with saved cloth. Unwilling to observe, she sat by an oil lamp stitching broad grip straps onto every shutter curtain. Bena complained the straps looked too soft, tested one herself, then withdrew the criticism.
伊沃的图摊在地面箱上。有人照着把长线接好，将多余的圈收起，免得天亮时绊住要撤的人。他坐着检查，每碰到需要爬高的位置就让别人去，困得闭眼片刻，又被自己的笔掉到地上惊醒。
Ivo’s drawing lay on the ground-level box. Others connected long wires and gathered spare coils so nobody withdrawing at dawn would trip. He checked from his seat and sent others to high places. Briefly closing his exhausted eyes, he woke when his pen fell.
Clay 给他捡起来，放到没受伤的那边。
Clay retrieved it and laid it on his uninjured side.
他没有再说一句坚持一下。
He did not ask him to hold on a little longer.
凌晨两点，各处按顺序报出准备完成。新镜仍全部遮着，普通灯照明，镇子还在旧光里。Dr. T 在主塔的准备纸上签了名，紧接着写明他此前继续使用旧参照、没有告知到人的事实，交给鸭嘴兽先生一并保存。
At two in the morning, each station reported ready in order. Every new lens remained shuttered. Ordinary lamps provided illumination; the town still lived in the old light. Dr. T signed the preparation sheet, then recorded his prior continued use of the old reference and failure to notify the people involved. Mr. Platypus took both into custody.
“你明天可能不记得为什么要写。”档案员提醒他。
“Tomorrow you may not remember why you wrote it,” the archivist reminded him.
“字还认得。”Dr. T 说。
“I’ll still read the words,” Dr. T said.
Clay 下楼时，看见那把修好的椅子被搬到走廊，咳嗽的孩子坐在上面，脚踩不到地。他母亲端着一只杯子，慢慢吹凉。
Descending, Clay saw the repaired chair in the corridor. The coughing child sat on it, feet above the floor, while his mother slowly cooled a cup.
旁路门已经开了。
The bypass door was open.
屋里的人仍需要有人给他们一口一口地喂水。
The people inside still needed water fed to them sip by sip.
