The geologists, under the able guidance of the Rev. T. T. Lewis, who has for 

 many years been known as a distinguished and successful investigator of the 

 Silurian rocks, made their way first to the north -field quarry, an excellent example 

 of the Downton sandstone. The characteristic lingula, with various superficial 

 markings, indicative of early vegetation, were here noticed. From this spot they 

 retraced their steps to Mortimer's Cross, and visited the Cross quarry, where the 

 Upper Ludlow rock is worked. Thence they shaped their course to the quarries 

 near Lucton, and afterwards entered the grounds of Croft Castle. In these 

 grounds, some noble oak trees (Quercus sessiliflora) attracted all eyes, their g^-eat 

 magnitude leaving the " Druidical " oaks at Bromfield, and other celebrated trees, 

 far behind. The trunk of one was found to measure, including some excrescences, 

 not less than 37 feet, and that of another 24.J feet in circumferance. Passing on 

 to Croft quarry, the party there examined the Upper Ludlow rock. A beautiful 

 wooded dell formed in the side of the lofty hill of Croft Ambury, excited much 

 both of admiration and scientific interest. This dell seemed to have originated 

 in a crack in the Upper Ludlow surface rock, which by the action of water was 

 gradually denuded so as to bring to view the Aymestrey rock beneath, leaving 

 precipitous cliffs, considerable in height This lovely ravine is interesting to the 

 tourist on account of the extensive and striking landscape visible from its upper 

 extremity, the view embracing a great part of middle and southern Herefordshire, 

 with the noble old tower of Leominster Church in the middle distance. We 

 described this view at length several years ago, when noticing the picnic of the 

 Herefordshire Literary and Antiquarian Society on this spot, in their excursion 

 to Wigmore, Croft Ambury, &c. 



Crossing the ravine, the geologists traversed the Oaken Copse on their way 

 to a quarry, which presents a prominent and beautiful example of the outcrop of 

 the Aymestrey rock. The rock dips at an angle of 37 degrees, underneath the 

 Upper Ludlow, and in the direction of the Old Red. From this spot they went 

 along the ridge to the Camp of the British monarch, Ambrosius, whose name, in 

 the corrupted form " Ambrey," it still bears. The view from this spot is one of 

 unequalled grandeur and beauty, while to the geologist its prominent points are 

 highly suggestive. To the nc)rthward, passing over the ancient lake of Wigmore, 

 long since converted into fertile meadows, the eye reaches in the extreme distance 

 Longmynd hill — said by some geologists to be formed of the oldest sedimentary 

 rocks in the world ; next, Stiperstones, a huge mass, once Caradoc Sandstone, but 

 by the protrusion of igneous matter, converted into quartz ; the broad summit of 

 the Brown Glee, and the lofty peak of Titterstone, capped with columnar basalt ; 

 whUe in the far east are visible the New Red Sandstone Hills of Worcestershire, 

 and in the south-east, the Syenitic Malverns, and the long line of Oolite called 

 the Cotteswolds. To the south, the eye ranges over the broad vales of Hereford- 

 shire, broken by hills of Old Red, and passes off to the Carboniferous district of 

 South Wales. Westward a sea of hills presents itself, vast billows of Old Red 

 Sandstone, among which the dimly seen Breconshire Vans (ban or van, high), the 

 waU-like Hatteral and its continuations northward, Radnor Forest, the Wimble, 

 and other innumerable summits meet the eye. After spending some time in
