abound on these hills ; it had two entrances, one on the north- 
west side, the other on the south-east, with a deep ditch and two 
outer ramparts, strengthened especially at the north-west entrance, 
the weakest point. The Roman road to Sarum passes it on the 
north, and doubtless this camp, like others of the same character, 
had once been occupied by the Romans, though he believed 
evidence of Roman occupation had not as yet appeared. Exca- 
vations alone could settle the point. Having stated that 
Black Down, away to the north-west, was the highest point of 
the range, being 1,067 feet, whereas this hill was only 979 feet 
above the sea level, he drew attention to the extensive view, 
embracing the Paleozoic ridge of the Quantocks on the south- 
west, the Oolitic plateau of Lansdown on the north-east, and 
the Greensand heights of Stourton on the south-east, whilst in 
the middle ground appeared the Liassie Tor of Glaston and the 
knoll of Brent, The Secretary then called on Mr. MceMurttrie to 
describe the geological features of the neighbourhood. Maps 
and diagrams were spread out on the valium, and the chief 
peculiarities of the strata explained. The members were stand- 
ing, he said, on the axis of the Mendip hills, on a ridge of 
Old Red Sandstone, and though they were unable to see any 
quarry section of these beds, yet the ground was covered with 
blocks of Old Red sufficient to indicate the nature of the rocks 
below. The Mountain Limestone dipped away north and south 
from this ridge, and upon their upturned edges the Secondary 
beds, ranging from the New Red Sandstone, through the Lias 
and Oolites, were deposited horizontally. As to the question of 
the cause of the disturbance which formed this anticlinal ridge, 
he pointed out on the diagram a great mass of igneous rock, 
which in his opinion (though he knew Mr. Winwood differed 
from him on this point) burst up through the centre and caused 
the disruption and tumbling about of the beds. A vast amount 
of denudation had taken place, sufficient to carry away many 
thousands of feet of superincumbent strata. Evidence of this
