A chainman calls a reading and a surveyor has about as long as the next sight takes to arrive to write it down correctly. Eight columns fix where each number goes before the sight is called: back sight, intermediate sight, fore sight, rise, fall, reduced level, distance, remarks. Nobody stops to rule a table in the field.

Ninety-six pages carry that table. Behind it sit thirty-three pages of squared paper at 5.0 millimetres, thirty-four rows to the page, for the sketch of the run and the arithmetic that checks it.

The page does not check the reduction for you. It only gives the columns enough room, in the same order every time, so a mistake shows up as a number in the wrong place rather than a number nobody can find.

What is inside

Levels: 96pp; Eight columns in a fixed order: back sight, intermediate sight, fore sight, rise, fall, reduced level, distance, remarks.
Sketch: 33pp; Squared paper at 5.0 mm for the run sketch and the check arithmetic.

In every book

The same six pages open every book: your details, who to call, the signs to point at when you have no shared language, and the map. They sit at the front because the moment you need them is not the moment to be flicking through.

This book belongs to: One page for your name and number, so a book that goes missing can come back.
My details: Blood group, allergies, who to call. Written once, carried everywhere.
Emergency numbers: Forty countries, taken from Wikidata property P2852 (CC0), agreed across two sources, every row carrying its QID. Numbers change and a book does not — verify locally on arrival.
Point at this: A pictogram grid captioned in English above and Indonesian below, for when there is no shared language.
World map: Natural Earth 110m, public domain, equirectangular, with UTC hour meridians computed from the projection rather than from a timezone database. For orientation and for pointing at, not a navigation chart.
Conversion tables: Computed from definitions — 25.4 mm to the inch — and not copied from anywhere, so every row can be checked by anyone holding the book.
Pen test leaf: The last page, printed for it on purpose. Every notebook is used this way; printing it deliberately is cheaper than losing the last leaf to it by accident.

The film

Page by page

A vertical film, 52 seconds: the cover, the ruling page, then 5 reference pages. Synthesised ambient bed, no dialogue — captions in three languages.

A vertical film from our own bench — this page contacts nobody's server to play it, and downloads nothing until you press play.

What is inside this book?

Five pages from the Level Book shown as cards: cover, divider, an eight-column reduction table page, a squared notes page, and a conversion table page. — Five pages from the print file: the cover, a section divider, a table page with its eight columns, a squared page at 5.0 millimetres, and the conversion table. The columns are the reason to buy this rather than rule an ordinary notebook by hand in the field.
