The north floor at Marrowloom smelled of warm tin and the thin syrup that keeps a thinking-stone from ticking itself hot. Ember Flint had the mop out because a banker had set his ledger on rack fourteen and the rack had sweated through the cloth. Blue tape circled the handles. The tape meant the stones were still adding sums for three shops in Las Pegasus and a weather desk that had paid through the thaw. A mare from the pledge desk read the tape as if it were a price.
By the time the syrup was wiped, the tape had company. Gold stickers, curling at the corners, named each rack as security for a note Marrowloom wanted out of Las Pegasus: four million bits, secured by the stones, the housings, and what the cover sheet called the uninterrupted right to the work inside. The stickers went over the tape. The customers stayed on the books. Nopony unlocked a rack.
Marrowloom rents the stones by the month to offices that need more sums than a clerk can finish. Keel & Bright cuts them, and ships a sharper stone whenever the old one starts to look paid for. The firm has been taking delivery faster than it takes receipts. On Tuesday its treasurer, Sable Quinn, told three pledge desks that idle capacity in the north hall could carry the note. The hall was not idle. Her memo used the word once, in the subject line, and did not use it again.
Luna Starlight's report reached the Friendship desk before the stickers dried. Report 441, "On Offering What Is Already in Use," runs six pages and thanks Marrowloom for turning a private rack into a lesson in shared weight. The last sentence is the one the pamphlet office prints in the margins of other ponies' forms. A friend who pledges the tool she is still holding teaches the room that trust can be counted twice. The report names the note. It names no renter. It does not name Ember Flint, who had already filled the line the form keeps for the pony using the stone if that pony is different.
Silver Hoof keeps the pledge book for the three houses in the deal. He stood under rack fourteen with his cuffs clear of the syrup. "A stone that thinks is as good as pasture, if it thinks at the rate in the schedule," he said. An aide wrote pasture in the margin and crossed it out, since pasture is not replaced when a quarry publishes a spring cut. He initialed the schedule anyway. It lists twelve thousand stones. Eleven thousand carry rental marks through winter. The last thousand are the cut Keel & Bright stamped prior on a sheet that reached the loading door while the bankers were still on the stairs.
The scrap card pinned above the mop sink prices a prior stone at a third of the pledge. The note insures the racks at the new-cut price and borrows against the old one. The gap, about six hundred thousand bits, appears in Report 441 as a generosity difference. On the card it appears as a date.
Ember waited until an aide needed the form she had signed. Somepony had drawn a hoop around her second line and written see lesson. She left the hoop. "They counted every rack with blue tape," she said. "Blue tape means a customer has the work until the thaw. I said it twice. They took the count and left the tape."
A runner from the weather desk came for a stone that now wore a gold sticker and a friendship-office seal, the wax used on lesson packets, pressed over the latch. Ember spent the better part of an hour worrying it loose with a butter knife so he could take the work he had paid for. The wax went into the envelope marked questions. Quinn, on her way to read the report a second time, told him the delay was "a kindness with a rate" and that his sums were "helping a larger trust." He took the receipt. He left the report on the sink.
Keel & Bright's spring cut sat two streets over in crates stenciled with the same rack numbers and one extra mark. The note uses the numbers without the mark. Quinn told the desks the new stones would "deepen the lesson" once they were uncrated. The pledged stones would stay where they were, still rented, still listed on page six as unencumbered.
At dusk Ember peeled the gold stickers off the racks the morning customers would collect. She put them in the questions envelope, under the wax. Inside the hoop she wrote the second line again, in pencil. The blue tape stayed. The stones went on adding somepony else's weather.
