The first and lower is 374 feet above the sea, contains some 

 arenaceous marl, some thin layers of Clay, many Flints, (some 

 quite fresh in fracture), Millstone Grit, granular white Quartz, 

 Quartzose Pebbles, and hard Chalk ; and the second, and 

 higher pit is of very large size, differs greatly in character, 

 although forming a sequence, and rests upon the upper beds 

 of the lower pit, containing many pieces of lower hard White 

 Chalk, also some Eed, (both, perhaps, from Lincolnshire), 

 large angular cretaceous Tlints in great abundance, (many of 

 quite fi-esh fracture). Granite from Cumberland or Scotland, 

 fine grained Trap, with glassy felspar. Millstone Grit, from the 

 Coal measures, White Quartz and Quartzose Pebbles, Moimtain 

 Limestone, some new Red Sandstone, White Lias, (very 

 deceptive, resembling Chalk,) Gryphaea cymbia, and incurva, 

 Amm: angulatus, semicostatus, Rhynchonellse, and Belemnites, 

 with one small fragment of Oolite.* 



Gravel of like character is found in great abundance in the 

 surrounding locality, extending to Long Compton ; but after 

 leaving that village, and ascending the hill by road, I failed to 

 find any. 



Returning to the Mickleton Tunnel, a good section of which 

 will be found in Mr. Gavet's paper in the Quarterly Journal 

 of the Geological Society for 1853 — as the sides of the cutting 

 and spoil are now much covered with grass I think it better 

 to give an extract from his paper : — 



" The surface of the ground at the summit of the tunnel is 

 490 feet above the sea, it is on a level with the Marlstone of the 

 hills on the east and west, and is composed of loamy siUcious 



* It was, doubtless, from this pit that Dr. Buckland, in his paper on " Valleys 

 of Denudation and Beds of Diluvial Gravel in Warwickshire, Oxon, and 

 Middlesex," mentions having " found Pebbles of a hard red species of Chalk, 

 which occurs not unfrequently in the Wolds of Yorkshire and Lincolnshire, 

 but is never met with in the Chalk of the south or sovith-east of England. The 

 nearest possible point, therefore, to which these Pebbles of Red Chalk can be 

 referred, is the neighbourhood of Spilsby, in Lincolnshire. With these Pebbles 

 of a Eed Chalk, are others of a hard and compact White Chalk, such as 

 accompanies the Red Chalk in the two last-mentioned counties, and which 

 occurs also at Eidlington, in Rutlandshire."
