About two miles further, Mr Moore directed attention to a 
remarkable land-slip which occurred in 1844, carrying forward 
three acres of ground—with forty oak trees upon it—a distance 
of 200 yards. 
In Perton Lane, the cutting through the Aymestry Lime- 
stone beds of the Upper Ludlow was examined. In places 
the beds are nodular, and when the nodules are broken open 
there is generally found in the centre of each, either the fossil 
Lingula Lewissi or Atrypa reticularis, which forms the nucleus 
of the nodule. 
Through the kindness of Lady Emily Foley, the members 
were permitted to go by her private drive to St. Ethelbert’s 
Camp, on the summit of Backbury Hill, where, according to 
tradition, Ethelbert, King of the Hast Angles, went to “ Offa 
the Terrible,” King of Mercia, at Sutton Wells, and while 
there, courting Offa’s daughter, he was murdered A.D. 792. 
Mr Piper pointed out that the Camp was doubly entrenched 
on the North side, and was more oblong than circular in shape, 
with an area of about four acres, and the highest point was 
767 feet above the sea. Standing upon what is called Adam’s 
Rock, Mr Piper—with the aid of some beautifully executed 
diagrams—gave a very clear explanation of the Woolhope 
Dome, and referred to the works of Sir Roderick Murchison 
and Mr Symonds on the subject. He especially called atten- 
tion to the enormous denudation which must have taken place 
in removing and carrying away the central dome. 
So much has been written upon Woolhope in all the best 
text books, and it is so classical a spot in Silurian Geology, 
that I do not think it necessary to enter into details. I would, 
however, remark that the Trap Rock at Bartestree may be 
found to have an important bearing in determining the time 
when the beds were uplifted from the horizontal position in 
which they were deposited. 
Thence through some narrow lanes to Mordiford, where 
Mr Piper gave the following history of the village :— 
“ At the Norman invasion the Manor was held by Almit— 
a free Saxon—by lease from Ethelstan, Bishop of
