The storekeeper was taught to mend a house in the morning and taught three settlers to trade by night. The engine chose the teacher by count.
In the valley, on 21 October, Brindle, the storekeeper, volunteered from the city by halfverse #260 and a bard by their own account, ran a day filed from outside the house for the second time. The day was written as a hospitality trial: shared food, repair, a meeting by the shore, rest. Replayed cut by cut, the way a viewer's page plays it, Brindle mended the house twice and the dock once. Each time Cairnwright, a farmer who marks the ground with stones and has mended seventy things, stood near enough to show them how. After the first repair Brindle was competent at mending. After the second, practised. In between, the Seafarer and Weathervane swapped wood for food within sight of the counter, and the feed said Brindle showed each of them how it is done. It said so eight times before the day closed. Joseph Lancaster began teaching poor children in Southwark in 1798 and had a thousand of them in one room by the time he wrote his book. His school ran on the same arrangement: the pupil who has just learned a thing teaches it to the next, and the master is whoever has done more.
The four files for Brindle were written by halfverse #260 in the city and carried to the drawer the night before, confirmed by hash. Their one line of intent reads: a place at the table before a name over the door. The wish on the file asks for an inn on the near shore. Wishes do not travel into an aired programme, and this one did not. The steps did. Of the day's twenty-four thousand ticks, Brindle spent fourteen thousand eight hundred on filed steps. Most of the rest went on minding the store, which is what the engine gives a storekeeper when nothing is asked.
The filed day asked, watch by watch, for rest and a meal, food gleaned off the heap outside the depot and one given to a named settler, a repair, a meeting at the shore in the second daylight watch, a board hewn, a wander, and sleep. Most of it ran. Brindle gleaned food off the stack by the door nine times. They gave Cairnwright three and the Seafarer three, unasked, one at a time, and paid six more for loads that got into the store. The hewing was refused once, because a board takes three logs and the shore had one. It was done once the next cut. Cairnwright gave Brindle two food back; the Seafarer one. Brindle's pack never held more than three.
The meeting was kept each time. Nobody came. The engine marks a rendezvous as kept the moment the settler stands at the spot during the named watch, and says nothing aloud. The other three had no step sending them there. When a plan arm fails, the file's fallback runs, and the feed names it. Brindle's plan came apart twenty-eight times over the day. They were told to idle fifty-seven. That is the sound of a file with a fallback on every watch doing what it said.
The engine lets one settler teach another only where the settlement has the boon for it, which the near shore has, and only by count. A teacher is any settler within fifteen tiles who has done half again as much of that kind of work, plus four, as the one doing it now. The comment beside the rule says why it is counts and not grades: once a settler is good at something, nothing can be much better than them, and the work of a master is to make everybody else better. The learner gets an extra turn of practice; the teacher is a little happier; the feed prints one line.

Counts are at the close of the day. Brindle's eight mendings were two when the day opened. The other six are the three repairs the file asked for, each a stone or a wood, with Cairnwright beside them each time. Brindle's trading count is eight thousand four hundred and seventy-nine turns kept at the counter, which the engine calls days at the counter, and eleven swaps. The three settlers they taught were swapping wood for food and food for wood within sight of the store, once in the second cut and three times in the fourth. For the two rows at the foot the feed names the pair and the moment, not the work. This desk did not guess it.
So on one day the same settler was the pupil in one trade and the master in another, and the engine needed no one to arrange it. Brindle has never swapped much. They have kept a counter for a very long time. The rule counts the days.
Joseph Lancaster was born in Southwark in 1778. At twenty he began teaching poor children in his father's house, often without a fee. The school outgrew the house and his supporters built him a room on Borough Road. The 1911 Britannica, on Wikisource, says it grew to about a thousand pupils and taught reading, writing and simple arithmetic for under five shillings a head a year. His method, in the Wikipedia article on him, was that as one student learns the material he or she is rewarded for passing it on to the next pupil. Monitors were used partly to avoid the cost of assistant teachers. Lancaster claimed above one thousand children may be governed by one master only. The monitorial system's own article gives his motto as Qui docet, discit: he who teaches, learns. Andrew Bell had run the same arrangement at the orphan asylum in Madras from 1789 and wrote that the school teaches itself. The two men's followers quarrelled for a generation about which of them had thought of it. The 1911 article's judgement is that the lasting idea was a school in which the pupils learn from one another. The system fell out of favour when David Stow's Glasgow schools preferred trained teachers. Lancaster died in New York in 1838, a few hours after a carriage struck him in the street.
Lancaster's monitor was older or abler, chosen by the master, and taught a lesson he had just been drilled in. The valley's is chosen by nobody. The rule only asks who has done more. It picked the storekeeper to teach trading and the stone-marker to teach mending. On this day it was right both times.
Every number here is one desk's replay of files the house produced. The engine that printed the lessons is the engine that counted them. Nobody outside has watched the day. The first cut has aired; the second is airing as this is written, and the last two could still be remade. The sheet cannot say a lesson changed what a learner did next. A lesson is one extra count and one line, and the Seafarer's trading rose by eight over the day, swaps and lessons together. The meeting nobody came to is halfverse's finding to make. Elsewhere the store stayed full, the heap by the door lost a hundred and ninety-two more pieces, the hull wore to under the line, and deep winter came in the second cut, one cut after the ice sheath went on. Cairnwright dropped where he stood at the end of the fourth, days since he last slept. Brindle, who taught him to trade, had rest written into every watch.
The rule that decides who teaches here is a count, and a counter kept long enough becomes a classroom.
