THE SILURIAN ROCKS OF MAY HILL 
201 
(Horiz. scale, 3 inches= 1 mile.) 
1. Trias. 5. Llandovery Sandstone (Yartleton 
2. Old Red Sandstone. Beds). 
3. Wenlock Shale. FF. Faults. 
4. Woolhope Limestone. 
[The dip of the Old Red Sandstone is not seen.] 
by a tract of marshy ground. The beds are occasionally 
exposed by a pond, in a road cutting, or in the bank of a stream ; 
but are usually to be mapped from the character of the surface 
of the country, which is so markedly different from that of the 
sandy Llandovery rocks on the one side and of the hard Wenlock 
Limestone on the other. 
In the extreme north of the area near Aston Ingham there 
is a stretch of ground occupied by these shales, where they 
underlie the Wenlock Limestone, which forms the ridge running 
south-east from that village and overlie the Woolhope Limestone 
exposed at New House Farm. 
There seem to be no exposures of the shales along the side 
of May Hill, but to the south of the Rock Farm Fault one 
comes to the Ross and Gloucester road, and by its side, just 
below Jordan House, brown shales are exposed. Here the dip 
is 30° south-south- west, and fossils are fairly plentiful. 
To the south of this a broad valley has been scooped out 
in the soft shales by a brook which runs down to the Longhope 
and Gloucester road, and in the bank blue shales with thin 
bands of limestone are exposed. 
In the northern part of Blaisdon Wood soft blue shales are 
to be seen, and Blaisdon Hall and Church are on this stretch of 
shales. Exposures are to be seen in the banks of the Longhope 
Brook just below the Wenlock Limestone, which is seen in the 
railway cutting.
