18. Bank House. 



Only about 20 feet of strata can be seen in this cutting. The 

 limestone is light-grey, with but a few traces of fossils. The beds are 

 at first horizontal, and at the northern end dip 5° north-westward. 



19. Heathcote. 



At the southern end, and through a greater portion of the cutting, 

 the beds dip 15° in a south-easterly direction, but at the Buxton end 

 the dip decreases to an angle of 5°. There are several fissures, or 

 pockets, in the limestone, filled with sand and clay. The sand is not 

 a quartzose sand, but is probably derived from a decomposed dolo- 

 mitic limestone. 



The limestones in this cutting are, like those in the Cold-Eaton 

 cutting, divided by way boards of clay. They were not carefully 

 examined for oolitic structure, as I was unable to visit the Heathcote 

 cutting after I had found the oolitic limestones in the Cold-Eaton 

 cutting.
