of Shipston-on-Stour, to form almost a complete Geological 

 series of English rocks from amiong tlie rounded fragments which 

 often occur in boulders of very considerable size." He makes a 

 similar remark of the country west of Market Harborough. 



The source, however, of many of the rounded Brown Quartzite 

 Pebbles, appears to be from the Conglomerate beds of the l^Tew 

 Red, and the White Quartz is from the Lickey and the Wrekin. 

 The carboniferous Limestone is probably from Derbyshire, 

 also the Coal-measure Sandstones. Some of the Syenite from 

 Charnwood, and the coarse Granite resembles that found in 

 Cumberland and Scotland. 



The great quantity of Quartzose Sand, occurring at nearly 

 all elevations, is clearly derived from the New Eed, and on 

 reference to the maps of the Geological Survey of England, 

 it will be seen how much that formation, even now, surrounds 

 and forms part of the district we have under investigation, and 

 how enormously it must have been denuded. 



My impression is that the N.D. Pebbles, which are now found 

 on the upper part of the Cotteswolds, are probably of the same 

 age as those which cap in such abundance the higher ground 

 of the Lickey.^ 



The evidence of Water Action. There are no boulders on 

 the high grounds of the Cotteswolds where the N.D. Drift 

 Pebbles are first found, and as I have before remarked, in 

 fields where there is hardly any Soil there are few, if any. 

 Pebbles, indicating a considerable amount of water action ; 

 and in a conversation I had with Mr. Thomas Brown, of 

 Barton, Cirencester, one of the oldest Geologists of our hills, 

 he told me he had observed the same characteristic in his own 

 neighbourhood. 



After the upheaval of the land which left the higher plateau 

 of the Cotteswolds dry, and down to the level I have indicated 

 of the coming in of the Flints, some great transporting agent 

 seems to have prevailed, bringing with it, from a considerable 



* Wten at the latter, a few days since, I found Cornulites serpularius from the 

 Wenlock beds.
