1873.] SHARP — OOLITES OP NORTHAMPTONSHIRE. 233 



"Weekly and Geddington. 



The road from Kettering to Stamford skirts the valley of the 

 Ise upon its north-western escarpment ; which presents, beyond 

 Weekly, the same succession of beds as before, but which in the 

 interval have been somewhat disturbed by a small fault, having a 

 south-west and north-east direction: — 



■ Great Oolite Limestone. 



Upper Estuarine. 



LINCOLNSHIRE LIMESTONE. 



Lower Estuarine, "I -«- ,, , -, 

 -ci • x> j > Northampton Sand. 



Ferruginous Beds, J L 



Upper Lias Clay. 



A little further on, at a short distance south of Geddington, is a 

 quarry in the Lincolnshire Limestone *. The Upper Estuarine Clay 

 is just seen coming in at the top ; below this, is a thickness of 15 feet 

 of Lincolnshire Limestone (the lowest bed but one consisting of the 

 hard Nerincea zone, as at Glendon) ; and at bottom, a reddish sand, 

 representing the Lower Estuarine Series. 



Section at the South Geddington Quarry. 



1. Upper Estuarine Clay (just apparent). 



2. Lincolnshire Limestone — ft. in. 



a. Marly oolite, in thin bands, and much shattered, about ... 6 



b. Soft marly limestone, containing few shells — burnt for lime 3 



c. Hard sub-crystalline bed, blue-hearted, in three or four 

 courses, containing numerous Nerin&a ciwgenda, N. tripli- 

 cata, &c. — the fossils standing out in relief upon the joint 

 surfaces, from the action of water charged with carbonic 



acid 3 



d. Shaly soft bed — "very rotten" — about 3 



3. Reddish sand — Lower Estuarine. 



The village of Geddington is situated upon the Upper Lias Clay 

 of the Ise valley ; and is celebrated for its beautiful Cross, the most 

 elegant of the three crosses which remain of the twelve erected in 

 a.d. 1290, by Edward I., in memory of his Queen, Eleanor of Castile. 

 It was built over a spring of ancient celebrity. Its material is 

 Barnack Rag, and it is nearly as perfect as when erected, never 

 having been restored. 



Just north of Geddington, is Bippen's quarry in the Lincolnshire 

 Limestone. The section is of the same character as that in the 

 quarry south of Geddington ; but the limestone beds have thickened 

 to about 20 feet. 



Fossils found in the two quarries : — 



Hinnites abjectus, Phil. sp. 



Pecten personatus, Goldf. 



Pinna cuneata, Phil. 



Pteroperna pygmsea, Mor. cf Lye. 



Modiola Sowerbyana, dJ Orb. 



Trigonia hemisphairica, Lycett. 



Unicardium impressum, Mor. §■ Lye. 



Natica Leckhamptonensis, Lycett. 

 Nerina?a cingenda, Bronn. 



triplicate, Bronn. 



Pygaster semisulcatus, Phil, ("petri- 

 fied mushrooms " of the pitmen). 

 Pecopteris polypodioides, Lindley.
