About 44; miles south-south-east, the Harford cuttings show some 

 5 feet of a freestone characterized by small Ostrece, overlying the 

 Harford Sands. I presume this is the same bed in an attenuated 

 condition, and without any distinct deposits of Snowshill Clay. So 

 that on the Banbury & Cheltenham Eailway at Harford the deposits 

 are : — 



Lower Trigonia-gr\t. 



Freestone (equivalent of the Tilestone). 



Harford Sands. 



But on the south-east, at Cleeve Hill the deposits are : — 



Lower Trig onia- grit. 

 Snowshill Clay. 

 Harford Sands. 



And farther away, at Leckhampton Hill, there is Lower Trigonia- 

 grit, only a trace of Snowshill Clay, and no true Harford Sands. 



If the position of the Tilestone above the Harford Sands be 

 correct, it was quite to be anticipated that it would not be found 

 to extend to Leckhampton Hill. It might have been expected, 

 however, at Cleeve Hill, though in an attenuated form, as at Harford. 

 But there is every reason to suppose that this Tilestone, in what 

 may be called a recognizable thickness, is a particularly local 

 deposit, only fully developed in that district of the North Cottes- 

 wolds which borders the Buggilde Street. 



The recognition of the Tilestone as above the Harford Sands, and 

 distinct from the Upper Freestone, is an interesting point; and it 

 would be desirable to have more information on the matter. The 

 sequence of these deposits certainly requires to be worked out in 

 more detail. The position of the beds shown in Section IX re- 

 quires to be better established. 



I measured with a level some exposures at Sudeley Hill, with the 

 following result : — 



Ft. 



From Notgrove Freestone to Harford Sands 45 



From Harford Sands to Oolite-Marl with Tere- 

 bratula fimbria 25 



From the 45 feet may be deducted 20 feet for ragstones (see 

 Section I b, p. 131), and so the results would be : — 



Ft. 



(1) Ragstones {Gryph<sa-, T. Buckmani-, and Lower 



Tril^owia-grits as in Section I b) about 20 



(2) Snowshill Clay, Tilestone or its equivalent, and 



Harford Sands 25 



(3) Upper Freestone, and perhaps some Oolite-Marl... 25
