Vol. 62.] HIGHEST SILUEIAN EOCKS OF THE LUDLOW DISTEICT. 209 



Two feet above road-level the Platyschisma-Bed (E b), which is 

 here ' bony/ may be noted ( = Downton Bone-Bed) ; and at the com- 

 mencement of the river-path, on the eastern side of the road, the basal 

 members of the Temeside Shales (F) may be observed : they are 

 obviously disturbed by the proximity of the fault, and plunge down 

 steeply towards it. 



The basal Temeside Shales (F a), consisting of rubbly shales asso- 

 ciated with greenish micaceous grits and containing Lingula cornea, 

 are also well-exposed along the road running southward from the 

 bridge, and again on the top of the hill to the west of it, along the 

 track leading to Burrington Hays. Farther south-west along this 

 same track, the Downton Bone-Bed and the Ludlow Bone-Bed too 

 are seen once more. 



(b) North-east of Downton Castle. 



Another confirmatory section is also to be found along a road 

 which leaves the main road to run north-west and south-east, along 

 a gul]y between Downton-Castle garden and the Brakes Wood. 



In the main road close to the Downton-Castle lodge the Chonetes- 

 Beds (D) are well seen, dipping at 8° S. 10° E. ; while close below 

 the main road, where the side-road makes a big bend, the Spirifera- 

 elevata Beds (D b) are exposed. A few yards farther east the Downton- 

 Castle Sandstones (E) come on, and have been extensively quarried 

 on both sides of the gully. The most interesting exposure is that seen 

 on the south side, where an excellent junction between the Downton- 

 Castle Sandstones and the Temeside Shales may be studied. At 

 the northern end of this quarry, about 20 feet of Downton-Castle 

 Sandstones may be seen, the upper 11 feet being the thinly- 

 bedded micaceous sandstones (E e), while the lowest beds seen are 

 the carbonaceous sandstones (E d). A deeply-weathered band 

 6 feet from the top may represent the Fish-Bed, but it is not clearly 

 defined. The highest members of the thinly-bedded sandstones 

 acquire a greenish tint and mealy texture, and pass gradually up 

 into the rubbly shales (F a), 15 feet of which are exposed at the 

 southern end of the quarry. The section is then obscured for some 

 little distance, but at the corner where the road bends more to the 

 south-west, the olive shales with the Temeside Bone-Bed (3 inches 

 thick) may be observed ; while, in a small quarry east of the School- 

 house, the Old Red Sandstones are seen. 



(iv) The Downton-Castle Inlier. 



In this inlier there is a practically-complete succession of the 

 highest Silurian rocks, from the Chonetes-Beds of the Upper Ludlow 

 Group into the Old Red Sandstone. 



Upper Ludlow Group. — The lowest members seen are the 

 Chonetes-J$eds (Da). These are exposed on the southern bank of the 

 Teme north-east of Forge Bridge, where they dip south-eastward at a 

 low angle, forming the lowest portion of a steep cliff some 60 feet in
