some interesting sections of Inferior Oolite resting on light-blue 
Upper Lias Clays, and a highly fossiliferous exposure of 
Marlstone and Lower Lias, leaving their description for some 
future occasion, and glancing at the Conglomerate cutting at 
Chileompton halt before the remarkable section about to be 
described. Immediately to the left of a stone bridge which carries 
the road called Broadway Lane from Radstock to Old Down, and 
opposite a house recently burnt down, called Lynch House, is a 
cutting about forty feet in depth through beds of a most varied 
colour. Though the attention of the members was first called to 
this pretty section by Mr. Mc Murtrie during one of the autumn 
excursions in 1873, the weather was so wet at the time that a 
cursory glance only could be given. The section, however, 
appeared to me of sufficient importance to be photographed ; this 
was shortly afterwards done, and the result is before you this 
evening. It required, however, several subsequent visits to clearly 
define the proper sequence of the beds, owing to the disturbance 
which had taken place since they were originally deposited. 
You will observe that these beds are not in their original 7.¢. 
horizontal position, but have been squeezed up into the form of 
an inverted cone, and constitute what is called a synclinal fold. 
To account for this we must call in the aid of faults and a 
considerable amount of lateral pressure. You will see on one side 
of the section (No. 13) a shoulder of Conglomerate appearing ; on 
the other side, to the east of the bridge, the same formation occurs. 
Now this palseozoic water beach is a much older formation than the 
beds which rest against it. So that in the first place one of those 
minor faults which abound in this our coal-field must have 
occurred dropping those upper beds down and sinking them 
below their proper horizon; then a subsequent squeeze 
between the two older and more solid formations in either side 
caused them to be broken up and dislocated in the way seen. 
Whatever may have been the case with similar beds in other 
places it is evident that these were not deposited in a trough form.
