Wick Trimming

Definition and Scope

Wick Trimming is the regulated reduction of a burning or dormant lamp wick to a length, profile, and carbon load permitted at that stage of the wick's service life. It is distinguished from wick dressing (the cosmetic combing of fibres), wick feeding (advancement through the aperture), and wick replacement, which is a matter for the Wickwright and not for the trimmer. The distinction is not ornamental: under the First Edict of Lamps, only trimming may be performed without a fibre licence, and a trimmer who feeds a wick has, in the eyes of the Guild of Lamplighters and Wick-Trimmers, replaced it.

Trimming is performed by Wick Trimmers, a licensed custodianship whose ranks include, since Year 644, the adherents of the Free-Wick Collective. The measurements governing every cut are set out in the Standard Wick-Length Tables, of which the physical master copies are held at the Wickery by the Keeper of the Wick.

The Cut and Its Authorities

A trim is defined by three quantities: the residual length above the aperture collar, the angle of the cut, and the carbon burden removed. The Tables specify all three by stage, from Aperture I (newly drawn wick) to Aperture V (a wick whose service is concluded but which has not yet been formally retired). A trim that removes carbon without shortening is recorded as a sweep and is logged separately, a distinction that has caused no fewer than eleven disputes over the counting of trims per annum.

Authority to trim is layered. The Guild issues the licence; the Keeper of the Wick issues the Aperture I token without which no trim-apprentice may make a first cut; and the Concordant Law governs appeals. The Third Concordance, Annex 4, fixes the permitted deviation at half a grain by weight or one stroke of the blade, whichever is the lesser, and adds the familiar caution:

"No trimmer shall trim by eye alone, nor by the eye of another, nor by the memory of either."

— Third Concordance, Annex 4

The Department of Ambient Physiology and the Office of Ledger Salt share the duty of trimming the wick-niches on Floor 909, an arrangement that has never been popular with either office and is renewed each year without discussion.

Floor 909 and the Winter of the Long Stub

The most cited incident in trimming history occurred on Floor 909 in the winter of Year 812, when a relief trimmer, unfamiliar with the niche schedule, trimmed forty-one wicks to Aperture IV specifications while the floor was still registered at Aperture III. The errors were not detected for nine days, by which time the wicks had drawn down at a rate the Tables do not anticipate. The Office of Ledger Salt's account records that "the floor was found to be burning at the length appropriate to a floor two stages further along its life, and no one could say when this had begun."

The subsequent inquiry produced the so-called Stub Ruling, which requires that any trimmer working a floor not on their customary schedule must first read the niche register aloud in the presence of a second officer. The rule is still in force. It is also, by common admission, never observed on floors above 1,400, where the registers are kept in a room with no lamp.

Wick Fibre and the Licence Question

Because trimming does not touch Wick Fibre as such, it falls outside the procurement monopoly granted to the Lampwrights' Guild by the First Edict. This is the settled reading, but it has been unsettled twice. In Year 703 the Guild of the Guttering Flame argued that a trim which exposes fresh fibre constitutes a taking, and therefore a procurement, and therefore a breach. The argument failed before the Department of Jurisprudential Anomalies on the ground that a trimmer removes and never acquires — a finding the Department itself later described, in a Chrono-Forensic Audit of Year 1,104, as "an artefact of the sequence in which the question was asked."

The Philumological Controversy turned in part on the same question, and readers are directed there for the fibre-theoretical consequences, which are considerable and largely unresolved.

The Free-Wick Position

The Free-Wick Collective, founded by Ambrose Wick in Year 644, holds that trimming is a devotional act rather than a licensed one, and that a wick trimmed in good faith is correctly trimmed whatever the Tables say. The Collective does not dispute the measurements; it disputes their authority to bind. Its adherents trim without tokens and record their cuts in private ledgers, several of which have been seized and none of which have been successfully read, as the ledgers are kept in a shorthand that resembles, but is not, the Guild's.

The Guild of Luminary-Menders has declined to take a position. A Lumen Tender of the third grade, asked in Year 1,190 whether the Menders regarded Free-Wick trims as valid, replied that the question was "above my wick" and referred the matter upward. The referral has not returned.

Record-Keeping

Every trim is entered in a floor ledger with the time, the aperture stage, the residual length, and the trimmer's mark. The logs of wick trimming are transmitted in detail to the Office of Visual Resonance, which has received them continuously since Year 588 and has never, in the surviving correspondence, requested them to stop. Ledgers are retained for two hundred years, or until the floor is renumbered, whichever comes first. Floors renumbered within the retention period keep their ledgers under the old number, and the cross-index of renumbered floors is maintained by the Wickery.

The Forty-Seventh Concordance requires that a trimmer's blade be wiped after each cut. It does not say with what. Practice varies by floor, and the variance is not recorded anywhere.
