Nicknames derived from the mining industry -
Dai Six Months (lost part of an ear in an accident),
Blackdamp (named after the deadly creeping gas found underground)
Sprag (named after the sprag of wood used to slow up the coal drams when on a downward slope) and so on.
These nicknames are a wonderful record of life in the pits and should be preserved.
John W of Treowen, Newbridge
