I 64 WORGRET HILL AND WAREHAM WATER SUPPLY. 

 REPORT TO THE TOWN COUNCIL OF WAREHAM. 



" The position of Worgret Hill is towards the centre of the 

 syncline or trough of Wareham, so it is probable that the 

 Bagshot Beds may attain considerable thickness at this spot. 

 The mouth of the Well is situated almost on the 100 feet 

 contour, and the sea-level line would thus lie towards the base 

 of the Higher Bagshot Clay series (B. of the tabular column). 



" The actual surface is formed by Q feet of Plateau-gravel, a 

 Pleistocene formation which occupies much of the elevated flat 

 between the North and South Rivers, and which has its easterly 

 termination at Worgret. This Plateau-gravel rests upon the 

 Higher Bagshot Sand series (A. of the tabular column) at the 

 Well, but a few hundred yards towards the S.W. it is seen resting 

 on the Higher Bagshot Clay series (B. of the tabular column). 

 From this circumstance it may be inferred that there is a 

 considerable dip of the Bagshot Beds in a north-easterly 

 direction probably about three degrees. Hence the natural 

 discharge of water from this Higher Bagshot Sand series is 

 towards the North river, and in this direction springs are thrown 

 out where series A (sands) rests upon series B. (clays). (See 

 Fig. 2 for confirmation.) This also represents the uppermost 

 water-line of the well section about 50 feet below the mouth. 

 The outcrop of this Higher Bagshot Sand series is so limited 

 that there could only be a moderate supply. 



"The Second Bagshot Sand Series (C. of the tabular column) 

 represents the chief water-bearing strata, and the upper part of 

 this series is pretty tightly packed by more than 50 feet of the 

 overlying Bagshot Clay (B.). Assuming the same dip of 

 3 towards the north-east to prevail, this sandy series should 

 hold a large supply of water from the region lying to the south- 

 west. It is from the upper part of this series that the actual 

 supply of water in the Well is obtained. There appears to be no 

 apprehension as regards the quantity of water. Yet no amount 

 of rest from pumping seems to have much effect in causing a 

 diminution of the fine sediment. I can onlv sav that further
