Camerton, and Dunkerton, terminating at Combe Down. On 
this was shown the separation of the coal measures by the 
intervention of an immense mass of coal measure sandstone 
known as the Pennant rock. The upper division embraces what 
are locally known as the first or Radstock, and the second or 
Farrington series, which are separated by about 600 feet of 
unproductive strata. The thickness of the Pennant is about 
3,000 feet, and then comes the lower division, which, like the 
upper, has been sub-divided into what is known as the third or 
New Rock, and the fourth or Vobster series ; below this comes 
the millstone grit (commonly called by the miners the farewell 
rock), and then the mountain limestone. The total thickness of 
the carboniferous strata was shown to be 1,210ft. The faults 
met with in the Timsbury Collieries were particularly referred to 
on the section. Some of these were afterwards pointed out 
underground, and examined with interest. 
An inspection of the underground workings was then made, 
the party being joined by the rector, the Rev. L. Rendell, and 
his son, and being under the guidance of Mr, H. S. Smith, the 
manager of the mine. A visit was first made to the great vein, 
the chief of the seams which have made the Timsbury Collieries 
so famed in Bath and the neighbourhood for their high quality 
house coal. The various methods in use of hauling coal under- 
ground, including a steel rope haulage, were inspected, and 
explained by Mr. Smith. Arrived at the coal face, the actual 
work in undercutting and breaking out the coal was viewed with 
great interest, some of the party obtaining for themselves 
mementos in the form of coal broken from the solid. The 
method of working, the form of packing, the gateways, and 
timbering under different circumstances was explained and 
examined with considerable interest. Returning to the shaft the 
party was lowered to the bottom of the pit, a total depth from 
the surface of 350 yards, On the way to the lower pit the party 
inspected the horses and stables, and viewed with interest the
