On the extension of the Northern Drift and Boulder Clay over the. 
Cotteswold Range. Read at the Annual Meeting of the Cotteswold 
Club, at Gloucester, April, 1878. By W. C. Lucy, F.G.S. 
In the paper which I read at the meeting of the Cotteswold 
Club in April, 1869, on “ The Gravels of the Severn, Avon, and 
Evenlode, and their Extension over the Cotteswold Hills,” I referred 
to, and gave an analysis of a peculiar Clay found in the 
fissures of some of the Oolite quarries, in which small quartz 
pebbles were found, and stated that I was not aware of the 
existence of Boulders or Boulder-clay on the high ground of 
the Cotteswolds, unless on further investigation this Clay 
should be found to belong to that period. (Vol. V. page 3.) 
During the time I was carrying on my researches upon the 
Drifts, I noticed, as recorded, (Vol. V. page 109) that on the 
high ground of the Cotteswolds, where there was hardly any 
soil, the N. D. pebbles were rarely found, and that Mr. Brown, 
of Cirencester, had observed the same thing, (Cotteswold Club, 
vol. V. page 116) and that I had not found N. D. pebbles at a 
higher elevation than about 750 feet. I could not however 
understand how that could be the measure of the submergence, 
and I determined to make further investigation. 
In a subsequent communication to the Club in March, 1873, 
“On the Submerged Forest at Holly Hazle,” I mentioned that 
continued observations had brought to my knowledge the 
presence of Boulder-clay over the Cotteswolds, which I hoped 
soon to shew; and in fulfilment of my promise I now proceed 
to lay before the Club the information I have acquired on the 
subject.
