Deene to Collyweston. 



As between Northampton and Kettering the road passes over the 

 Great Oolite Limestone and subjacent beds, varied by the occurrence 

 and recurrence of hill and dale, so between Deene and Collyweston, 

 passing through the villages of Bulwick and Duddington, the road, 

 with a like variation, traverses the Lincolnshire Limestone for a 

 distance of seven miles. No peculiarity worthy of notice occurs on this 

 line ; and I will, therefore, diverge, at Fineshade, for the sake of 

 noticing a rather remarkable section at Wakerley, one mile to the 

 west, and quarries, notable for the fossils they have yielded, at 

 Morcot, two miles beyond. 



Wakerley. 



The section at Wakerley exposes a series of beds in the Lincoln- 

 shire Limestone, having an aggregate thickness of about 30 feet ; 

 the whole of which, from the top to the bottom, are exceedingly 

 (some coarsely) oolitic ; and several exhibit false-bedding. Five or 

 six courses of the lower part of the section are like the " Rag " at 

 Weldon, and full of imperfectly preserved shells. I obtained from 

 the " Rag " beds, Pseudodiadema depressa, Ag., and a fine spine of 

 Gidaris Foivleri, Wright*.

8. " Eag " bed (like the " Bag " at Weldon), full of shells, 



chiefly minute, imperfectly preserved — in four to six 



courses, some very false-bedded 6 to 8 



Between the nearly adjoining villages of Wakerley and Barrow- 

 den, flows, over the Upper Lias, the river Welland ; which, through- 

 out almost the whole of the southern boundary of Rutland, serves 

 as the line of demarcation between that county and Northampton- 

 shire. 



* Mr. Judd, I believe, has obtained a large number of characteristic Inferior- 

 Oolite fossils from this quarry.
