WORGRET HILL AND WAREHAM WATER SUPPLY. 173 



must regard the Bagshot outcrops on the south-west slope of 

 Worgret Hill as, in the main, representing the Second or Lower 

 Sand (C), which measures 62 ft. 6in. in the well and borehole 

 section. Decidedly it appears to be much thicker on the 

 outcrop than in the well and borehole section, whilst on the 

 other hand the Higher Bagshot Clay- series (B) is, on this outcrop, 

 less than a third of its thickness in the well-section. All this 

 looks as though the sands were thickening at the expense of the 

 clays in this direction, and thus the Higher Clay-series (B) may 

 be a more or less lenticular body thinning out in a south-easterly 

 direction. The only other place where I have noted a clay out- 

 crop hereabouts is in the railway-cutting on the south side of 

 Worgret Bridge (see Plan, Fig. i). This seems to be an 

 attenuated representative of the Higher Clay-series in an easterly 

 direction, and may possibly hold up water towards the base of 

 the Higher Sands (A) if people at the top of the hill would only 

 sink deep enough. There can be very little doubt, however, 

 that, when the Worgret railway-cutting was made, the supply of 

 water from the Higher Sands in the immediate locality was 

 seriously impaired ; the drying up of the old wells at Worgret 

 Farm was a proof of this. 



When we try to interpret the results attained at Worgret Hill 

 by means of the numerous boreholes, great and small, it is 

 more than ever a matter of regret that the principal borehole was 

 not completed to the Chalk. We should then have been in 

 possession of a most excellent basis for comparison, and might 

 have been able more effectually to correlate the strata in the 

 central section with the outcrops towards the south-west. The 

 distance from this hill to the nearest Chalk outcrop in the Wool 

 district is about 3^ miles. Whilst allowing for rolls in the strata, 

 the general inclination between the two points is probably a 

 little east of north-east, as the result of the northerly dip due to 

 the syncline in conjunction with the prevailing easterly dip of 

 the basin of East Stoke. 



Omitting the Lower Tertiaries and confining ourselves to the 

 Bagshots in this traverse, we find (i) a thick sandy series well
