THE AVONIAN OF THE AVON GORGE 
121 
III. THE SECTION ON THE LEIGH WOODS SIDE. 
Seeing that the sequence on the right bank of the Avon has 
been so fully dealt with, it will be unnecessary to give a detailed 
account of that on the left bank. The descriptive account which 
follows consists, therefore, of a series of short notes explanatory 
only of the most striking facts, and especially of those which 
cannot be so satisfactorily observed on the Clifton side of the 
river. 
We may conveniently start from Clifton Bridge Station and, 
before entering on the riverside traverse, it will be advisable to 
visit the quarry on Rownham Hill. 
If the hill be ascended as far as the fork in the road, the left- 
hand branch must be taken and the quarry then lies a short 
distance farther along, on the right hand side of the road. (If 
Clifton Bridge Station is reached from the Suspension Bridge, the 
quarry should be examined on the way down.) 
‘ Rownham Quarry ’ lies in the upper part of the Dibuno- 
phyllum-Zone. (D2), and in the repetition of the Carboniferous 
Series, south of the Great Fault. The lowest beds exposed in 
the quarry are massive limestones poor in fossils ; these beds 
are worked for road metal. Resting upon these massive beds 
is a thick bed of rubbly limestone which contains numerous 
patches of clay, and it is from these patches that the finest 
specimens of D2 corals have been obtained.

which have been collected from Rownham Quarry ; —
