ASIIBURNIIAM STRATA. 
221 
1. Loam, of an oclireous, or grey colour, with 
thin layers of friable shelly limestone. 
2. Compact blue limestone with bivalves (pro- 
vincially termed grejjs), alternating with shale. 
3. Comj)act blue limestone and shale, alternat- 
ing in layers of from 14 to 20 inches each in thick- 
ness : these are almost destitute of organic remains. 
There are not less than fourteen or fifteen alter- 
nations of the limestone and shale, making a total 
thickness of upwards of 100 feet. The workmen 
informed us, that the beds at Archer’s AVood 
generally dip towards the south, or soutli-west : 
the inclination of the strata, however, from the 
disj)lacement they have suffered, is so variable in 
different localities, as to render it impossible to 
obtain an approach to accuracy. The faults are very 
numerous : one of them is so considerable, that it 
is called the “ Sixty Fathom Fault.” Strata of a 
similar kind are worked in Darvel’s AVood, about 
four miles north-west of Battel ; at Brightling, on 
the estate of John Fuller, of Rose Hill, Esq. ; near 
Burwash ; at AVest Down, AVillingford, and Hurst 
Green.* 
One of the most interesting localities of these beds 
is at Pouncefordy on a farm belonging to the Earl 
of Ashburnham, situated in a deep glen, about a 
mile to the right of the turnpike road, leading from 
Cross-in-hand to Burwash. 
• At Tethani, about a quarter of a mile from Crowhurst Place, near 
Battel, the workmen employed in digging calciferous grit, discovered 
vertebrae, and bones of the extremities of an enormous reptile, in soft 
ferruginous sandstone ; traces of ferns were also observed. Some of 
the bones were preserved through the discrimination of Nathaniel Kell, 
Esq. of Battel, w ho kindly added them to the collection of the author.
