occurred in clusters — lying upon it, followed by the base of the main mass of 
Lower Limestone. A few years ago the section showed the Sandy Scissum- 
Beds immediately underlying the lowermost Limestone bed, and provided a 
considerable number of an unnamed Terebratulae. The Sdssum-Beds are now 
quite hidden. Attention was called to the circumstance that the Pisolite 
beds, which were such a marked feature at Leckhampton and Crickley, had 
not been found at Painswick Hill, and that in all probability the Pea-Grit 
series never extended much farther west, although Mr. Richardson had dis- 
covered that it had a considerable easterly extension. It was also pointed 
out that the Cephalopoda Beds, which were so extensively developed to the 
southward, were not completely represented here, although the uppermost 
beds of the series in a very attenuated form were to be found at Haresfield 
Beacon. Attention was also drawn to the local faulting, which was a feature 
of nearly all the hill slopes, and it was suggested that these were caused by 
the accumulation of water in what is now the Severn Valley, and that this 
was in all probability caused by the diversion of the Severn from its original 
course. Whether that course was northward into the Dee, as some authorities 
think, or eastward to the Thames system, it is practically certain that this 
accumulation caused a considerable lake to form, the shores of which must 
for a long period have remained at about the 150 feet contour line, and 
resulted in the accumulation of the extensive gravel beds at that horizon. 
The date of the commencement of the formation of the lake is uncertain, but 
it must have had a considerable extent in Pleistocene times, and the barrier 
at Sharpness was in all probability breached during or shortly after that time. 
The Geological Map showed that just where the breach occurred and where 
the Severn now flows there is a complex of faults, which was consequently 
a weak spot, and one where a breach would be most likely to occur, and 
having once started might be expected to proceed very rapidly. 
A move was then made to the Camp, which was crossed under somewhat 
uncomfortable conditions, and the party proceeded towards Cranham. Before 
Cranham was reached, however, it became clear that the proposed walk down 
the valley would occupy more time than was at disposal, and the party 
proceeded by the shortest route to Painswick. 
Tea having been disposed of, the following Candidate was balloted for and 
elected : — 
Miss G. I. Fyffe, Trullwell, Box, Minchinhampton, proposed by E. W. 
Fyffe, seconded by W. A. Lucy. 
BOURTON-ON-THE-WATER MEETING. 
September 4TH, 1920. 
The fourth Field Meeting of the year 1920 was held at Bourton-on-the- 
VVater district on September 4th. 
Members met at Bourton-on-the-Water under the direction of the Rev. 
H. J. Riddelsdell, and proceeded to Bourton Bridge, and thence along the valley
