NAMHO conference summary
Friday evening
Mark Horton, the animated Professor from Bristol Uni well-known to Time Team fans, gave an energetic overview of the place of Bristol in the story of industrial Britain. He seriously ran out of time, which was a great shame, not because of the by then cold fish and chips which I hadn't ordered anyway, but because I would have loved to hear what else he had to say on the subject. The room was packed with delegates standing at the back. The popularity of Professor Horton needs to be set against the fact that there were no field trips on Friday evening.
Saturday morning
With all of the intellectually challenged delegates safely out of the way exploring muddy holes, the remainder of us had a nice air-conditioned hall to ourselves. Much of Saturday was devoted to really local subjects which I much appreciated as I knew very little of the area's mining history.
Dr. Nick Chidlaw set the scene with a good overview of the geology of the Bristol coalfield which set later presentations into an understandable context.
Dave Hardwick followed this up with a summary of the mining that has happened in the area over the centuries - coal, celestine, stone, iron and lead.
Steve Grudgings' talk described the story of the last deep mine in South Gloucestershire - Frog Lane Colliery which closed in 1950. This was illustrated with some really excellent contemporary photos both above and below ground.
Neil Macmillen then demonstrated his research into the fullers' earth extraction industry in the Bath area. This was of particular interest to me since I was brought up next to the much larger opencast operations for fullers' earth in Surrey, and although I had always been aware that the clay was dug in the Bath area, I knew little about it. The nature of the processing plants shown brought back some memories of places I explored when young in the woods and fields at home. Seeing photos of fullers' earth mines was great, as there were no significant working underground operations in Surrey, not in my time anyway.
Saturday afternoon
Steve Grudgings again. Steve described how the Coalpit Heath mineworkings were drained, with details of the Newcomen engines and adits that were driven. There are significant remains in the form of old engine houses and foundations. Because much of the coal field was abandoned a long time ago, before the age of "land restoration", mine remains were left to quietly moulder and decay, and often there are more things to be found today that you would find in a more recently abandoned coal mining area.
Trevor Thompson is an expert in the planning, engineering and construction of the Severn Tunnel, and went into much detail on the problems encountered while the tunnel was dug, and how they were overcome. The dramatic effect of the opening of the tunnel was that overnight cheap coal from Wales was available in locations formerly served by the local mines which inevitably went into decline and closed.
Penny Fernando has been part of a team investigating early coal mining sites in the Forest of Dean. She described three sites where, with the use of LIDAR surveys, early mine-workings surface remains have been surveyed. The presentation showed how the patterns of craters can be matched against the seam outcrops, and also demonstrated that a different mining technique other than "bell pits" was used in the centre of the Bromley Hill area, which much resembled a pattern of shafts I have seen in 19th century limestone workings in East Sussex.
Peter Claughton rounded off the day with a talk that emphasised the importance of NAMHO's Research Framework for the Archaeology of the Extractive Industries. He emphasised how important it is that valuable research done by volunteers, or by others, which has been quietly placed on a shelf and hidden from wider view is brought to light. Planning and conservation work by the likes of English Heritage can only be done taking into account what is known to them through Historic Environment Records, and if our work is not part of that then we should not be surprised if out favourite mine sites disappear under a new supermarket.
Saturday evening
All the field trippies returned to join the conference die-hards for a really good dinner. The food was plentiful, tasty, and extremely well presented. Nobody was left wanting, and beer was laid on to help wash it down. A hat was passed round for a tip for the catering staff, but we then discovered that as local authority employees they were not allowed to accept gratuities. A decision was reached and well over £100 will be on its way to Macmillan Cancer Relief.
Sunday morning
Derek Hawkins knows a lot about Bath stone. A well-illustrated presentation showed us the methods of working which developed over the centuries, and the modern extraction tools that are still used. Derek worked for a while in a working quarry, and latterly has worked in the MoD sites at Corsham. He had a good number of really good photos of the defence sites while they were still fully equipped.
Dave Hardwick then explained a little-known extractive industry - for celestine in the Yate area. Strontium sulphate deposits were considered of such value that the expansion of Yate was only possible as each field targetted for development was cleared of this rare mineral. Celestine is no longer dug in the area.
Alan Gray took us on a virtual surface tour of the Redcliffe area before showing us what lies beneath in the old sand caves. A fascinating site which I have been to in the past but must return to some time.
Dr Lynn Willies demonstrated the fascinating recording work that took place in the Combe Down quarries at Bath before they were filled up with concrete. What a shame that it takes the necessary destruction of a historic site to get such an excellent piece of recording done.
Dave Hardwick again! Mine historians will know about the work of J.C. Burrow in Cornwall, recording underground scenes there in the 1890s. They may not be so aware of a similar set of photos taken in the Bristol Coalfield which have been tracked down and collated. About 50 plates have been found, of equal quality to the Cornish photos, and Dave also related the story of how the photos were taken, and the work done to track them down again.
Sunday afternoon
Steve Tofts is a member of CHERT a group that is investigating the history of lead-mining and processing at Charterhouse in the Mendip Hills. Steve presented a case for the dams in Velvet Bottom to be Roman in origin, although as he freely admitted, this is a controversial line of thought and yet to be proven. What is clear from the talk is that lead-working on the Mendip Hills is a very poorly researched subject, with a few notable exceptions.
Alan Gray took the stage for a second time. This talk was about ochre-mining on and around the Mendip Hills. I was surprised to learn the extent of the industry and how recently it stopped. Alan is publishing a book on the subject in the near future.
Geoff Fitton has been involved in the study of copper mining in the Quantock Hills. Geoff told us the history of the copper mines at Dodington, and what remains to be seen today.
The Clifton Railway was a four-tracked funicular railway that ran mostly in a tunnel close to the Clifton Bridge. Maggie Shapland presented the history of the railway along with details of work done there in recent years to preserve what remains.
This was a well-organised event and much appreciated by those who attended.
