Talus to the base of quarry ..... 



This quarry has a long face from west to east, the beds as a rule rising 

 towards the east. The top bed (No. 1) is in the upper level at the west end 

 and No. 2 vertically below it in another level. From this spot the beds, rising, 

 form a continuous face, the upper part of which is No. 3. The beds below 

 the junction bed (No. 4) are of a different character, more massive, and though 

 shelly they are not rubbly. These are taken to represent beds on the horizon 

 of the Forest Marble, and not of the Cornbrash. I cannot make the beds 

 below the rubble correspond in thickness with those recorded by H. B. Woodward, 

 but, as the face is long and the basal rubble thick, this probably represents 

 the characteristic variation of Forest Marble. The fact that a very large series 

 of fossils was here obtained by Rev. H. H. Wood, seems to be due to all the 

 beds having been taken as Cornbrash. Amongst his collection are found numerous 

 Gasteropods not known elsewhere, which have not been here included as Cornbrash 

 fossils for this reason. 



6. Stourton Caundle to Wincanton. — There are two quarries between 

 Bishop's and Stourton Caundle with Cornbrash confined to the top layers, 

 and more massive beds below ; they require caution therefore in collecting. 

 There were also recorded a quarry at Stalbridge Weston and others along the 

 ridge that runs via Templecombe to Wincanton. But I could neither find them 

 nor hear of them, and conclude they were temporary exposures or even railway 

 cuttings. The road sections at Wincanton are peculiar, and their character as 

 Cornbrash I was unable with certainty to recognise. 



7. Feome District. — The neighbourhood of Frome shows the Cornbrash perhaps 

 reduced to its minimum ; it scarcely makes a feature below the flat surface of 

 the Oxford Clay. There is seldom more than three or four feet of it, and when 

 the rubble of which it is made is extracted, the openings are again closed. 

 Such may be spoken of as " shallow openings." There is seldom a chance 

 of including any Forest Marble fossils with theirs, for the openings seldom sink 

 so far. One such has been made on the north-west of Berkeley. At Road the 

 sides of the two roads leading down from the village to the river show a 

 thicker mass of very loose rubble, but the quarry on the west side of the river, 

 about half a mile north of the village, is in " blue shelly limestone " and is 

 not, therefore, free from doubt. Chatley, whence some of Sowerby's fossils
