Gravel, Sand, and Red clays, to a depth of 76 feet, disposed in 

 layers, resting immediately upon the upper beds of the Lower Lias 

 Shale. The following is the order of the beds downwards, viz. : 



Vegetable soil, about 



Loamy Sand and Pebbles 



Fine Loamys and, passing into coarse 



Gravel and Clay 



Eed Clay, with boulders of Marlstone 



Loose shingly Gravel 



Red Clay, with boulders of Marlstone 

 Lower Lias shale, more than 



"The Sands and Gravel are limited to about 170 yards on 

 either side of the tunnel, and have an anti-clinal arrangement, 

 the beds dipping irregularly north and south, in one instance 

 the Gravel dips 15° to the west. 



"In the Sand and Gravel beds there were found but very few 

 Shells, which were principally GryjjJicea and a few Belemnites, 

 but in the lowest Gravel bed the Fossils were more numerous, 

 consisting mostly of Belemnites, Gryphcea, Serpulce, and all 

 having the appearance of being much water- worn. 



"The beds of Red Clay are non-fossiliferous, but contain large 

 detached blocks of Marlstone, of a bluish colour and of uneven 

 fracture, and with the edges considerably rounded by attrition. 



" At the south of the tunnel, in the Red Clay, large 

 Marlstone boulders were embedded, very much rounded by 

 attrition, similar to those above mentioned; they were from 

 one cwt. to three tons weight each."
