Chapter the First
Of the Great Problem
067° 30' 00″ WFor three centuries the seas swallowed ships not for want of brave hearts, but for want of an answer. A vessel could measure latitude by the noon sun — but longitude, that elusive east-west truth, eluded the finest astronomers of every court.
Galileo proposed Jovian moons. Newton suggested lunar distances. The Spanish Crown offered ducats; the Dutch, florins; the British Parliament, in MDCCXIV, offered twenty thousand pounds to whomever could solve it within half a degree.
longitude.quest is a society for those who still hear the echo of that wager. We hide answers along meridians. You walk to find them.
Chapter the Second
The Form of an Expedition
022° 30' 00″ Wi. The Ledger
Each fortnight a single longitude is published — a slim corridor of land and ocean running pole to pole. Within it, a clue is buried.
ii. The Chase
Solve the cipher by reading the field. Photograph the stone, the bridge, the bench, the tree. Send it sealed with the timestamp.
iii. The Reward
Your name is engraved upon a small brass disc. Your initials are inked into the master chart kept at the Society's reading-room.
iv. The Honour
We do not race. We do not rank by speed. The chart honours the careful eye and the patient foot.
Chapter the Third
Of Instruments and Implements
022° 30' 00″ E- Marine Chronometer. A faithful watch carried to sea. Compare its time to the local noon, and the difference is your longitude. We furnish a digital one, but a real H4 we will gladly admire from afar.
- Sextant. For the angle between sun and horizon. Useful in the field, ornamental everywhere else.
- Field Book. Cotton-paper, sewn binding, oilcloth cover. Issued to every member at the third successful chase.
- Pencil. A real one. Wood. Graphite. We are firm on this.
- Patience. The most precise instrument we know.

A Covenant of Coordinates
135° 00' 00″ EWe are not a company. We are not an application. We are a small society of correspondents who believe a place is best understood by walking to it.
If this finds you on a quiet evening with a map unfolded on the table — write to us. The next meridian is published at the new moon.
