94 PROCEEDINGS OF THE GEOLOGICAL SOCIETY. [June 17, 



the oolitic limestone (d) is frequently quarried; and below it, especially 

 on the southern slope of Rowlston Scar, coal has been obtained 

 within the memory of man only a few feet below the oolite. 



About Carlton, Coxwold, Newborough Park, and Owlton, the lime- 

 stone is frequently exposed and dug in quarries ; and here also coal 

 has been found below it. At Newborough Park it was about 

 50 feet below the oolite, which is dug and burnt to lime. 



Brandsby. — Proceeding southward from the country of Thirsk 

 to the parallel of Easingwold, in the Howardian Hills, about 

 Brandsby and Gilling, we find the remains of old coal-works, ranges 

 of limestone, and quarries of roadstone, presenting on the whole the 

 following section : — 



Sandy series, yellowish -> ft. in. 



Roadstone, 2 or 3, or 4 or 5 feet; laminated sandy glance-lime- } 



stone, often full of shells, often in broad flat nodules, lying ^ 50

At no point further to the south-eastward has the coal-seam been 

 found worthy of opening, — it has indeed scarcely been traced ; but the 

 oolitic limestone, a few yards or fathoms below which it lies, conti- 

 nues distinct, and is quarried almost in a connected line, by Col- 

 ton, Dawby, and Terrington, to Bulmer and Crambe. The road- 

 stone is found above it distinctly only a short distance, and can 

 scarcely be identified beyond Terrington and Wiganthorpe. At 

 Welburn, Bulmer, and Crambe, white cement-stones occur below the 

 Oolite, as near Thirsk ; and below these are oolitic ironstone and 

 ferruginous sands, corresponding to the Dogger-series of Thirsk and 

 the coast ; but the strong white gritstones and most of the shales 

 which lie between the Oolite and the Lias about Brandsby, Kilburn, 

 and Boltby are almost absent from the banks of the Derwent. 



Crossing the Derwent, we trace in like manner the Oolite by
