 This boring appears to have subsequently reached a depth of 1655 

 feet from the surface without meeting any change of ground.

 There have been also borings, of which details are not forthcoming, 

 at the undermentioned localities : — 



Near Kingshill Spinney, one mile and a half south-west of Market Bosworth, 

 ending at a depth of about 672 feet, probably in Waterstones. 



At Bosworth Wharf, one mile west of Market Bosworth. 



At Cowpasture, three-quarters of a mile north-east of Market Bosworth, said to 

 have entered Cambrian or Lower Silurian rocks at 400 feet. 



Near Gabriel Pool, £ of a mile N.N.W. of Newbold Vernon, to a depth of 266 feet. 



Newbold Heath, half a mile W.S. W. of the Landridge boring mentioned above, in 

 which Coal-measures were said to have been proved at a depth of 400 feet. 



There can be little doubt therefore that, as pointed out by Mr. 

 Harrison, 4 the Trias rests directly upon rocks older than the Coal- 

 measures over a large part of the area. Whether or no the Coal- 

 measures were ever deposited continuously over the area remains 

 an open question. It is certain that the Silurian rocks had suffered
