134 ME. S. S. BUCKMAX ON THE BAJOCIAN [Feb. IpOT, 



The Harford Sands show that the Freestone with * Pecten 'perso- 

 natus ' cannot be the Upper Freestone where it immediately underlies 

 the Upper Trigonia-grit : it is evidently Notgrove Freestone. 



Another mile on the Old Campden Koad is Seven Wells. This 

 locality takes its name from the fact that the Snowshill Clay throws 

 out water copiously here. The following details may be noted : — 



Section YII. — Seven Wells. 



Snowshill IX. The fruit-trees near the farm mark the line 



Clay. of Snowshill Clay. Perhaps as much as 



20 feet of it. 

 Tilestone IXa. Below that is some stone, perhaps more or 



equivalent (?) less mixed with clay. 



Harford X. These are exposed in the field some 25 feet 



Sands. lower. 



Just south of Broadway Tower, which is about 1 mile north of 

 Seven "Wells, distinctive evidence of Snowshill Clay and Harford 

 Sands abounds. It would be quite easy to map them around here. 

 Besides exposures, the ploughed fields, the furze, the thorns, the 

 oak-trees show the limits of one or the other, as the case may be. 

 There must be a very considerable thickness of these two deposits^ 

 And in a roadside exposure I found stone, evidently higher than 

 the Snowshill Clay, which was in all likelihood Lower Trigonm-gnt. 

 Moreover, there is very likely Notgrove Freestone about here, for 

 H. B. Woodward speaks of Freestone with Pecten personatus as 

 occurring near the Fish Inn, Broadway.^ Certainly he puts it below 

 ' Oolite-Marl ? ' ; but what Oolite-Marl is like in this neighbourhood 

 is shown by the quarry near Chipping Campden, 1^ miles from 

 Seven Wells on the Old Campden Eoad (see Appendix I, p. 150). 

 Just before that exposure is a quarry showing tipper Trigonia-grit 

 resting on freestone with Trigonia signnta, which brings it into 

 line with the Snowshill exposure. The latter is really the key to 

 the whole. 



Section VIII. — Hear Campden Hill Farm. (South of Old 

 Campden E-oad.) 



Ft, 



Upper Trigonia- I. Somewhat rubbly, yellowish crystalline stone, 



grit. with Bki/nckonella subtetrahedra, Eh. ham- 



penensis, Zeilleria Waltoni, Terehratula glo- 



hata, Acanthothyris spinosa 2^ 



(Parting conspicuous. Top planed oflP, pitted, 

 covered with oysters, but not bored. An in- 

 constant band of stone above, with oysters, is 

 bored.) 



Notgrove Free- V. Whitish crystalline stone {Trigonia signata). 



stone. Eroadstone 7 



Note. — Denudation prior to the deposition of the Upper Trigonia-grit was , 

 very irregular. Some of the stone is greatly pitted and bored by a large 

 species of Lithodomus. There is a similar quarry near the Lodge on the left 

 of the bye-road leading to Northwick Hill Farm.
