and at 100 yards coal, broken, was found, but dipping headlong to the west, in a 

 similar manner to the sinking at Wigmore. The place was abandoned, and some 

 more trials have been made, but not successfully ; but still we are of Opinion that 

 the coal will be found under Upper and Lower Penn, Tettenhall, Codsall, Hilton, 

 and at depths varying to 800 yards, running away to join the Cannock Chase and 

 Hednesford Coalfields in the same manner that the coal wiU probably be found to 

 run from SandweU and Hamstead right away under Birmingham, &c., and join- 

 ing the Warwickshire Coalfield, where the Thick Coal, as in the Cannock district, 

 is divided into many seams. 



Practical geology has akeady achieved many triumphs, and we venture to 

 think the finding of the Thick Coal at SandweU and Hamstead is not among the 

 least of them, so far as the Midlands are concerned, and we may look upon the 

 future of this district in the mining world as assured, and especially when coal is 

 found, as above mentioned, on the west side of the old coalfield. 



FRIDAY, SEPTEMBER 3. 



The following Report and Papers were read : — 



1. Foiirteenth Report on the Erratic Blocks of England, Wales, and 

 Ireland. — See Reports, p. 223. 



2. On the Glacial Phenomena of the Midland District. 

 By Dr. H. W. Ceossket, F.G.S.—See Reports, p. 224. 



3. On the Glacial Erratics of Leicestershire and Warwickshire. 

 By the Rev. W. Tuckwell. 



As evidence of a south-western dispersion from Charnwood ; — in Stockton, a 

 village midway between Leamington and Rugby, a mass of boulder clay containing 

 abundance of Mount Sorrel granite, of so-called gneiss from Charnwood Forest, 

 large decomposed ' pockets ' of red sandstone, blocks of grey sandstone highly 

 glaciated, Bunter pebbles, flints, carboniferous limestone, lias rock of a difierent 

 texture from that native to the district ; also lying loose in the village street, re- 

 cently enclosed and inscribed, a fine boulder from Mount Sorrel, glaciated, of nearly 

 two tons weight were referred to. 



Mount Sorrel and the unmistakable character of its hornblendic granite were 

 described. 



The author noted extraordinary profusion of Mount Sorrel erratics as far as 

 Leicester ; at Rothley, Thurcaston, Anstey. ' Stone ' or ' Ston ' is a suffix of 

 nearly all the villages along the line. 



A notice was given of a special stone, the largest found in Leicestershire, near 

 Humberston, estimated at twenty tons, partly embedded in boulder clay which is 

 filled with Bunter pebbles and rolled slate from Charnwood. Its enclosure and 

 preservation were suggested. 



Attention was called to the reappearance of Charnwood stones from Leicester 

 to Coventry, from Coventry to Stockton, completing the evidence of a south-west 

 stream from the Charnwood elevation throughout the two counties. 



4. The Fossiliferous Bunter Pehhles contained in the Drift at Moseley, &-c. 



By A. T. Evans. 



The pebbles contained in the drift are chiefly composed of quartzite, intermixed 

 with fragments of silurian limestone, carboniferous chert, carboniferous sandstone, 

 and Llandovery flags ; also a few fragments of flint, granite, basalt, quartz, con-
