WORGRET HILL AND WAREHAM WATER SUPPLY. 163 



grains of a highly crystalline quartz : the larger fragments are 

 dull or fatty and range up to in. There is also a considerable 

 amount of dark coloured siliceous fragments, such as go under 

 the general term of " lydite." The remaining beds of the 

 Second Sand-series call for no special remark, being in general 

 character typical representatives of the Bagshot Sands of the 

 district. These are the beds which outcrop on the south-west 

 slope of Worgret Hill (see Fig. 5), but any attempt to correlate 

 them with their equivalents in the borehole section would not be 

 likely to meet with much success. They are stated to be wet 

 sands throughout the borehole, but do not appear to have yielded 

 any notable amount of additional water to the supply. 



The Pipe-clay Series (D. of the general section). As this 

 group is only known from boring, the arrangement of the 

 details is somewhat arbitrary since the several clays were much 

 mixed. There can, however, be little doubt that series D 

 represents the Pipeclay Beds of the northern and southern out- 

 crops, though inferior to the clays of the southern outcrop in 

 quality. Much the same varieties of clay as we find in the 

 Creech district came up from the borehole, and there was no 

 difficulty in recognising the greyish-white pipeclays alternating 

 with the inferior or variegated varieties known in the workings 

 as " two-ball" clay. There are, however, some differences, and 

 on the whole the samples of these clays do not seem to have 

 attracted the notice of the clay-merchants. The last 24 feet of 

 the borehole were gone through rather quickly, and no 

 particulars are given beyond the fact that the borehole terminated 

 in grey pipeclay at a depth of 215 feet from the surface, or 114 

 feet below O. D. 



At this juncture of affairs the Wareham Town Council 

 requested me to draw up a report (October-November, 1905) on 

 the geological position as revealed by the boring rod, and on the 

 possibility of a further supply of water either from the Tertiary 

 Beds or from the Chalk. At the risk of some slight repetition I 

 reproduce this report with the accompanying tabular column 

 (Fig- 4).
