10 LEDBURY DISTRICT. 



no sign of mctamorphism, or alteration by heat, within a few yards 

 of the trap bosses. The May HiU beds appear to have been deposited 

 on the trap floor of the old sea bed after it had become cold and 

 consolidated. Eastnor Park, the demesne of Earl Somers, falls 

 within the district of Ledbury, and there are few finer fields for the 

 geologist. 



The oldest known specimen of the Ptcrygotus, a Silurian lobster, 

 was found in the May Hill sandstone, at the base of the Obelisk 

 lull, by Mr. John Burrow, of Malvern. The devclopemcnt of 

 Upper Silurian rocks between the Obelisk hill and Ledbury is 

 very fine, and should be followed out by Netherton, and Awkeridge 

 Earms, to Chance's Pitch, and thence to Colwell by Wellington 

 Heath, where the Old Eed rocks may be seen flanldng the hills of 

 Hope End and the Frith Wood. The railway tunnel at Ledbury, on 

 the western side, enters in lower Ludlow rock. A little distance 

 within the tunnel there is a fault, and the Aymestry limestone is cut 

 through. The Wcnlock shale and limestone are then traversed, 

 being nearly in a horizontal position. The Lower Ludlow beds 

 again come in, followed by Aymestry rock. Upper Ludlow shales, 

 Downton sandstone, and, at the west end of the tunnel, by red and 

 mottled marls, grey shales and grits, purple shales and sandstones, 

 with grey grits containing abundance of a little fossil fish termed 

 Auchenaspis, and which constitute a passage into the Old Eed 

 sandstone proper, which sets in before we reach the Ledbury Station. 

 AVall HUls Camp near Ledbury, consists of Old Eed rocks, with a 

 crystalline cornstone, and bands of red and grey sandstone. At the 

 base of this hill is a thin band of impure grit, and cornstone, con- 

 taining many fish spines and scales. Henry Brooks, of Ledbury, a 

 working geologist, furnished me with many specimens. Cradley, 

 Castle Frome, Canon Frome, Munsley, and Pixley, are all situate on 

 the Lower Old Eed. At Cradley there is a valley drift deposit on 

 the line of the brook, *but considerably higher than the present water 

 shed. Lias shells were detected in this valley drift by the Eev. 

 E. P. Hill, some years since. The drift was evidently formed 

 in a valley where the waters opened out into the Severn straits. 

 Near Ledbury the valley drifts have furnished fossil bones, and 

 mammoth's teeth, as also at Clincher's Mill gravel pits, near 

 Eastnor. Bosbury, Coddington, and Mathon, arc all situated on the
