At the time I was planning to send this the other day, my computer came up with some sort of error message, so I am not sure whether it actually went or not. Sorry if it is just a repetition. In the discussion of mine records, someone mentioned mine surface plans. In my 1950 student report on Cadley Hill and Bretby collieries, south Derbyshire, now lodged with theDerbyshire County Record Office in Matlock (DRO Accession Number D 5444) I included plans of the surface buildings, railway sidings etc at both pits, drawn in the original to a scale of 60 feet to the inch. The Record Office has produced a printed version "A Report on Cadley Hill and Bretby Collieries Summer 1950 by A>A>C> Brewis, ISBN 0 901761 78 8, but in doing so they have omitted "because of technical difficulties" what I think of as two key drawings, namely (1) a general plan of the Swadlincote area showing railway lines and colliery locations, below which there is a geological cross-section of the area showing the principal coal seams, and (2) the surface layout plan of Cadley Hill colliery. (The similarly drawn surface plan of Bretby is included but, as this report is on A4 and the orgiginal was drawn on foolscap, the copy in the printed report is at a reduced size). I have queried the omission of what I think are two key illustrations and at one stage (almost a year ago) the archivist, Dr Margaret O'Sullivan, did say they were having another go at reproducing the drawings and she hoped to produce a second edition of the printed version which would include them, but I have heard nothing more and I guess nothing has happened. (If any persons on the list live near Matlock, it might help if someone could ask what is going on, and stire things up???). The surface plan of Cadley Hill ( I am sure there must be others on file, on which I based my drawings, so I cannot claim that my original is the only such record) might be of particular interest to historians as the mine site was, I understand, subsequently reworked as an opencast so all vestiges of what was there will have disappeared. One of the buildings was the engine house which held a winder whose drum had three sections of different diameters, as it had originally served (simultaneously!) three shafts of different depths. I believe this winder eventually went to Chatterley Whitfield, but I have no idea what its eventual fate might have been. Tony Brewis
