N tlie Quarterly Journal of the Geological Society for 1891 
-L p. 545, the late Edward Wilson remarks : — " Although 
the Rhsetic rocks have a wide horizontal distribution in the 
neighbourhood of Bristol, it is but seldom that they are exposed 
at the surface. In the absence of natural inland sections, 
and of quarries on the horizon of a thin series of rocks which 
yield no minerals of commercial value, we have generally 
to trust to new railway cuttings or other artificial excava- 
tions for affording us opportunities for their examination. 
appears desirable while it is in a fresh state. In a very 
short time the new cutting, which, like the old one, is 
sloped at so high an angle as to be almost inaccessible, will 
become obscured by rain wash and vegetation, and thus be no 
longer available for detailed examination." 
The foregoing quotation so accurately represents the state 
of the Rhsetic rocks in this neighbourhood that it is worth 
reproduction. All the sections previously described in this 
district are now built upon, grown over, or otherwise 
inaccessible. A detailed description of a new local section 
may therefore be of interest. Some fields near Bedland 
Oreen have been lately laid out for building purposes under 
A redescription of the Pylle Hill section, therefore,
