vol. xx. (3) THE SILURIAN ROCKS OF MAY HILL

of the hill above the old road, and in the wall which runs up 
the shoulder of the hill just to the south of Yartleton Farm. 
No other types of rock are seen in these walls. 
In the southern area, which covers Huntley Hill, there 
are more exposures to be seen in these beds. The dips, 
which are shown in the map, suggest faults through the 
Llandovery beds, but the scanty number of the exposures 
renders it difficult to place them on a map with any degree of 
certainty. 
On the south slope of Bright’s Hill, above the Ross road, 
there are old quarries showing the coarse Huntley Hill beds, 
and on the south side of Huntley Hill above the Longhope road 
are several workings showing yellow and red coarse sandstones, 
at times passing into a conglomerate. 
The latter type of rock is seen in the slopes above Broom 
Hill Wood, where the included pebbles run up to inches in 
length, are fairly well rolled, and consist of quartz and felsites. 
The coarse sandstone is also seen on Nottswood Hill. Wherever 
they are seen on these two last hills the Llandovery beds are 
dipping to the west-south- west. 
( b ) The Yartleton Beds. 
Overlying the coarse sandstones, which form the Huntley 
Hill beds, along the whole of the western slopes of the May 
Hill range of hills, come the Yartleton beds, which are frequently 
exposed. They are also seen elsewhere, having been shifted by 
faults. They must be about 470 feet thick. In the main they 
are fine yellow sandstones which are moderately fissile, but they 
become somewhat shaly below and contain calcareous layers 
in their upper part. 
The lowest beds seen are exposed in the old road about 
300 yards above Yartleton Farm. Here are layers of very fine 
yellow sandstone and brown shale, which have so far yielded 
no fossils. 
Above these (stratigraphically) comes a yellow fossiliferous 
sandstone containing a few layers of limestone near its summit. 
This can be studied both in a quarry close to Old Oaks Farm 
to the north-west of May Hill, where it dips 40° west below 
Woolhope Limestone, which is exposed in the road close by,
