The Calibration Room
Every pole in this building has a plate. The plate carries the marks and the numbers. The brass column only holds it up.
At the foot of every plate is what it measures, the range it covers and what each mark is worth. When those change, somebody comes with a ladder and changes the plate.
It takes a couple of minutes, and afterwards every mark on the column means something else. So in this wing the plates change in front of you, and the one that came off stays in the room, where you can see how big it was.
One more rule, because this wing is about time. Every figure on a pole here is in dollars of its own year. The lens from the last room stands beside each pole and restates the older reading when its index reaches that far, and says so when it does not.
THE LEDGERRead the plate before the pole.
The caretaker“They’re heavier than they look.”
What this room showsThe numbers on a ruler are printed on a part that unbolts; when the plate changes, the ruler means something else, so it should change where you can see it.
