THE aEOLOGY OF TYTHERINGTON AND GROVESEND. 6 



Limestone Shales. Towards Grloucester it rises along the 

 Old B-ed Sandstone, which, flanked by Triassic beds, over- 

 looks at first the stream-cut valley, and then the low-lying 

 country which stretches by Thornbury to the Severn. The 

 view from this road, before it dips on to the Trias, near 

 Buckover, is superb. 



The road from Grovesend to Tytherington rises over Old 

 Eed Sandstone, and then, after dipping into Lower Lime- 

 stone Shales, passes across the Mountain Limestone to Stow 

 Hill, when it drops steeply into the Triassic inlet on which 

 Tytherington is situated. 



2. The Raihcaij Section between Tytherington and 



Grovesend.. 



I have to thank the Rev. H. H. Winwood, M.A., F.G-.S.-, 

 of Bath, for introducing this section to my notice. We 

 visited the section together several times, and once in 

 company with Mr. W. L. Meredith, C.E., F.G.S. These two 

 gentlemen are publishing, in the Proceedings of the Cottes- 

 wold Field Club, a section, prepared by Mr. Meredith, and 

 descriptive notes supplied by Mr. Winwood. The section 

 published herewith is based on Mr. Meredith's,* the hori- 

 zontal scale being reduced to one-fourth, while the vertical 

 scale remains the same. My reading of the section differs 

 somewhat from that given by Mr. Winwood, but I have to 

 thank him for having, with great courtesy, sent me proofs 

 of his Cotteswold paper, in which he recorded some of the 

 measurements we made together. 



The section, — nearly one mile and a half in length,— runs 

 between the points A and B on the map which accompanies 



* By the kind permission of these gentlemen, and of the President 

 and Secretary of the Cotteswold Field Club.
