The Clay is well shewn in several places between Stroud and 
Miserdine, more particularly about Stancombe Ash. 
Again under the guidance of Mr. G. F. Puayne I visited Uley 
Bury, where, at a height of 760 feet, we found a considerable 
layer of Clay, with a good many N.D. pebbles in it, and in 
other parts of the hill, where there was less clay, as usual, there 
were but few pebbles. We went on to the Ridge, and in a field of | 
Great Oolite, near Symonds Hall Farm, on the opposite side of 
the road to the Tumulus, I found N. D. pebbles, and Mr. PLayne 
picked up a lump of Clay which was lying on the surface of 
the ground, and on examination we discovered two small Quartz 
pebbles in it. The pebbles and clay were of the same character 
as those which occur in the fissures of the Oolite quarries in 
various parts of the Cotteswold range. The clay I submitted to 
Professor Cuurcu, who wrote to me: “It is quite clear the 
clay has nothing in common with the so-called of the Forest 
Marble. It contains as much Silica as is present in China 
Clay, while the amount of Carbonate of Lime is quite insig- 
nificant when compared with that of the true Oolite Clays, 
which varies from 35 to 70 per cent. 100 parts of your Clay, 
taken in a perfectly dry state, gave 69°58 per cent. of Silica.” 
Within the last week I have found the same Clay on Painswick 
Hill, which, on analysis, was found to contain 68-2 per cent. of 
Silica. 
Accompanied by Mr. Brtiows I visited Cleeve Cloud, the 
highest point of the range, 1093 feet, which being table land, 
led me to hope we should meet with some evidence of the 
existence of Boulder-clay and N.D. pebbles. The Clay seems 
to have been prevented from resting on the plateau itself, by 
powerful water action; while it was protected from this action 
on the slopes, by its greater depth from the surface. This 
would account for the fact that it is usually thicker on the 
slopes than on the level land above. 
Within ten feet of the highest point, in a field which was 
being ploughed and had a good covering of clay upon it, Mr. 
Betiows picked up a veritable N.D. pebble. We took home 
two pieces of Clay from different parts of the field, which
