<A colleague was looking at an 1849 copy of OS 1:10560 Lancashire sheet 71 today and noticed the words 'Defaced' printed in two places close to Princes Colliery.> Tim, I woke up one of my ancient colleagues who is a former OS surveyor and he says that 'Defaced' is/was a mereing term used by the OS which means that the part or all of an item originally surveyed to mark a boundary has since been removed.

There are several other collieries in the area (Brandwoods and Closes) and a number of Old Coal Pits, but nowhere else does 'Defaced' appear. Does anyone know whether the words refer to the pit or are simply some OS code - for example a defaced Bench Mark? Tim Colman Nottingham
