The spare safety tether was thirty feet of triple-braided flax webbing, an inch and a half wide, soaked in boiled pine tar to resist the acid cooled water of the lower vaults.
Len had spliced the line himself on the Tram depot platform three days ago. He sat beside Bram Ash on an overturned ration barrel under the sputtering copper lanterns. He had learned the splice from his father during his fourteenth winter. Using a narrowed horn marlinspike to open the three laid strands. He tucked each strand over one and under two against the lay. He hammered the throat flat on an iron anvil plate before seizing the neck with waxed harness twine. In the Tern Road postal network, an honest splice was not an aesthetic flourish.
