SOME HERTFORDSHIRE WELL-SECTIONS. 
By W. Whitaker, B.A., F.G.S., Assoc. Inst. C.E. 
Bead at Watford, 19 th February , 1885. 
Since the publication of the Geological Survey Memoirs that 
refer to Hertfordshire, many accounts of wells in the county have 
come into my hands, and I think that such of thege as have a 
geological interest may he acceptable to the Society, including one 
which has been published elsewhere, but with the description of 
which I cannot altogether agree. 
Forty-one Hertfordshire wells have been noticed in vol. iv. of 
the Geological Survey Memoirs (pp. 447-456), and sixteen others 
in the Memoir on Sheet 47 (pp. 82, 83), whilst our members have 
recorded a few in the Society’s ‘ Transactions.’ * 
I take the double opportunity of thanking the various engineers 
and well-sinkers who have given the details that have enabled me 
to make this record of local facts, and of asking for others. 
Of the well-sections now noticed two are of special interest, 
namely the deep borings which reach the older rocks at Cheshunt 
and at Ware, as to the latter of which further information is needed, 
with regard to the Cretaceous beds.
