THE KNOLL REGION OF CLITHEROE, BOWLAND AND CRAVEN. 
A NOTE BY (the LATE) ARTHUR VAUGHAN, M.A., D.SC, F.G.S. 
(Read June 24th, 1915). 
Part of this region, to wit, Slaidburn in Rowland, was the venue 
of the Yorkshire Geological Society in Easter, 1915, and, by the kind 
invitation of the President and the courtesy of the Society, I was 
fortunate to participate in the visit. This excursion was directed 
by the President, Mr. R. H. Tiddeman, with the purpose of examining 
the Carboniferous Rocks which he had surveyed some forty years 
previously. The result went to confirm the impression that I had 
obtained, on former visits to other parts of the Knoll Region, that 
geologists were insufficiently acquainted with the information that 
had already been acquired, both with regard to the sequence and 
correlation of the rocks, and with regard to the important and broad 
conclusions which had been deduced from the mapping. I need, 
therefore, scarcely apologise for the publication of this brief summary 
which in so far as it concerns Mr. Tiddeman's work, has been mainly 
extracted from the Report of the International Geological Congress
