Proceeding north, the next fossil locality of importance is an old 
<]|uarry about a quarter-of-a-mile N.W. of the Tortworth Court Gas 
Works. In the map of Buckland and Conybeare this is marked as 
Barber’s quarry, and in the Sedgwick Museum the following fossils are 
labelled “Barber’s quarry”; — Theda sivinderenana^ Favosites hisingeri, 
Favosites forbesi, “ Monticulipora ” sp., Orthis basalis, Rhynchonella 
wilsoni var. davidsoni. 
Falfield Mill was formerly a rather noted fossil locality, and the 
older collections contain a considerable number of fossils from it, as is 
seen from the following list. At the present time, however, it is very 
difficult to find any fossils
