34 HISTORY OF COLCHESTER CORPORATION WATER WORKS.
miles back from the coast in order to sink a well into the chalk
without the risk of getting an excess of chlorine, and who must of
necessity rely upon gravel beds in their neighbourhood from
which to obtain a supply. Within the last few years I have
carried out several such schemes. Only a few years ago, in
conjunction with the late Sir Frederick Bramwell.. F.R.S., Mr.
Whitaker, F.R.S., and Dr. Thresh, M.D., D.Sc., I surveyed a
large part of the county not far from this town, in order to find a
water-supply for Clacton free from chlorine, and among the
sites selected was an admirable gravel bed at Great Bentley.
Other counsels then prevailed, the gravel bed was abandoned,
and a well sunk on the site, to the Chalk. This turned out a
failure, as one might have expected, and the gravel bed has
since been utilised as the only means of supply.
