FOLIO · IIOf the Nature of the Boo
In the year now passing, the Order at Fathom Station has set down forty-seven entries against the wall of the pressure hull, each one the record of a small, untraceable haunting that drifted through copper, fibre, or cellular silicon and was caught, briefly, by the hydrophone at three thousand eight hundred metres. We do not call them ghosts. The brothers who pre-dated us called them boo — the soft acoustic of a thing leaving a place it had no permission to occupy. The codex you read tonight is a transcript, illuminated by candle, of that listening.
The boo is not a being. It is the trace a being leaves when its signal outlasts its vessel. A payphone receiver, set down in 1987 in a town now flooded, will sometimes carry the half-second of a voice that was paid for and never spoken. A router, decommissioned and shelved in a copper-mountain, will issue, six years later, a single LED pulse against no electrical demand. We catalogue these. We do not interpret them. The interpretation is the candle's work.
Three classes are recognised: Vox, the voice-class, audible only to the wire that carried it; Umbra, the shadow-class, visible only as a brief failure of expected light; and Signum, the signal-class, registering only as anomalous packets at four in the morning. A single haunting may belong to one class, two, or — rarely — to all three. The reader is asked to consult the figure above.
FOLIO · IIIThe Catalogue
CATALOGVE · I
Echolalia consumeris
A common haunting of domestic routers more than seven years in service. The Echolalia repeats fragments of packets long since acknowledged — never the payload, only the handshake. Heard most clearly between three and four hours before dawn, on the quiet side of the equinox.
CATALOGVE · II
Vox aenea silentum
A receiver of brass and bakelite, weighed in the hand, carries the half-breath of a coin paid in 1987. Held to the ear, it offers nothing; held to the candle, it offers a pause that is almost a vowel. Belongs to the Vox class. Liturgical use: confession of debts unspoken.
CATALOGVE · III
Umbra cathodica
In the unlit corner of a back room, an unplugged cathode tube will, on the third night after the new moon, hold for one tenth of a second a green afterglow of a face it once carried. The face is never recognisable. It is, however, always smiling.
CATALOGVE · IV
Signum nocturnum maris
The dial of a ham-radio, untuned and grounded, will at irregular intervals settle of its own weight onto a frequency long since vacated. The brothers record these with a stylus-and-wax. The frequencies are never the same twice.
CATALOGVE · V
Lux fibrae aberrans
A splice case, opened at the seafloor for routine inspection, will sometimes release a small flare of light along its severed strand — light that left a transmitter in 2003 and arrived, late, in the present hour. We weep when we record this one. We do not know why.
CATALOGVE · VI
Hydrophona profundissima
The instrument from which this codex is transcribed. Lowered to three thousand eight hundred metres, sealed in titanium and prayer, it hears what cannot be heard above. On clear nights it reports only a silence too patient to be empty. On poor nights, the candle gutters in answer.
FOLIO · IVThe Live Hydrophone
WHAT THE HYDROPHONE HEARS TONIGHT
FOLIO · VColophon
This codex was set down at the Order of Fathom Station, a research monastery moored at three thousand eight hundred metres beneath the waters of the North Atlantic, in the present year. The candle by which it was illuminated was poured by hand at the chandlery of Bressay & Sons, of Lerwick, from beeswax pressed in the western isles. The wick is of plaited cotton, twice-dipped, and burns at the rate of one fathom per night.
Transmitted from the seafloor under the time-stamp . Set in EB Garamond, after Granjon. Rubrications by hand, in cinnabar. The reader is thanked for their patience; the night is long, and the boo is small, and we are still listening.
