of a dyke of volcanic trap rock (greenstone) haWng been forced, as seen in a quarry 

 at Loose Hill, about a quarter of a mile south of Bartestree Chapel, through a 

 fissure in the Old Eed ; whilst at Hagley Dome, about a quarter of a mile further 

 north, and a hundred yards west of Hagley House, the upper Silurian formation 

 is found protruding through the Old Red Sandstone. (For geological section of 

 this district see article "The Silurian Rocks of Hagley Park," on page 167 of 

 Woolhope Club Transactions for 1870 ; also " Geology of the Woolhoise District," 

 by Rev. Robert Dixon, page 170, et. seq. for 1867.) 



The facts (1.) of the directions of the trap dyke at Bartestree and the faulted 

 edge at Shucknall being both from W.S.W. to E.N.E. : (2.) of the parallelism of 

 this break with the fault at Mordiford : and (3.) that aline drawn through Gorsley 

 Common through Haugh Wood and Old Sufton would — if prolonged two miles 

 N.W. — pass through Bartestree Dyke and Hagley Dome, lead to the supposition 

 that they all occurred under the same exciting causes : it may be simultaneously. 



Our party quitted the carriages a short distance beyond the sixth milestone 

 from Hereford, at an altitude of 234 feet above sea level, and, walking up Pertou 

 Lane a distance of a few hundred yards, were joined by the Rev. Wm. H. 

 Lambert, Mr. Lambert, Rev. A. G. Jones, and Dr. Wood ; and later on by Mr. 

 H. Wilson, President of the Malvern Field Club. On arriving at Perton (Juarry, 

 opposite Perton Farm, we espied our President (who had driven from Ledbury), 

 hammer in hand, busily engaged in search of fossils in tliis disused quarry, which, 

 he informed us, was of the Upper Ludlow formation, and the very outer-most part 

 of the Woolhope upheaval, and here in the top beds of Upper Ludlow shales 

 might be found Pterygotus Banksii, Eurypterus Brodici, and other rare fossils, 

 while the inferior beds would yield abundance of Chonetci lata, with an occasional 

 Homalonotus delphmo-cephalus, Thcca, &c. After spending some time here, the 

 most noteworthj' fossils unearthed were, perhaps, a good s]>ecimen of the bivalve 

 Orthonota impressa, with its hinge distinctly marked, which was found by Mr. W. 

 H. Harrison, and some very well marked examples of the typical fossil, Chonetci 

 lata, and the pretty little Lingida named Symondsii, after the Rev. W. S. 

 Symonds. Quitting these strata of Downton Sandstone and Upper Ludlow, and 

 ascending the hUl by the same lane, we found ourselves in a cutting through what 

 our President termed the Middle Ludlow, or Aymestrey limestone, where half-an- 

 hour was occupied in trying to break the very hard nodules which were here found 

 in great quantities, of a size from a pigeon's egg to that of a barnacle, and of 

 which nearly every one contained a nut-brown Liiu/ula Leioisii, or other character- 

 istic fossil, sometimes found in a very well-preserved condition. This Linyula is 

 much larger than the Lingula Symondsii, and is the typical fossil of the formation. 

 Euomphalus carinatus, Spirifer plicalellus, Atrypa reticularis, Meristella tumida, 

 and Rhynchonella Wilsoni, with several Terebratula, were also found. Still further 

 ascending a hundred yards, we observed and visited a fine quarry on the right- 

 hand side, distant only a few score yards from the lane, of Aymestrey limestone, 

 which forms a wall around the greater part of the Woolhoiw Valley, extending 

 from the rock whereon we stood, away above Tarrington and Putley, and by 

 Marcle Hill right down to Oldbury Camp.
