EAST NORFOLK GEOLOGY— WELLS AT MUNDESLEY, 
NORTH WALSHAM, AND METTON. 
By Clement Reid, F.R.S. 
Read 24 th September, 1901. 
The last few years have seen the sinking of several wells, which 
throw light on the geology of an obscure part of East Norfolk. 
A short notice of two of these wells has already appeared in the 
‘Summary of Progress,’ of the Geological Survey;* but I have 
now obtained further information, which enables me definitely to 
fix the geological date of the doubtful deposits. 
The first well I have to describe is one sunk at Mundesley, for 
the supply of that growing watering-place. On a good many 
occasions, during past years, I had been asked by the local 
authorities how they could best obtain a good supply of water, and 
had recommended sinking to the chalk ; but the exact depth to 
that rock was still doubtful, a trial-boring made by the Geological 
Survey not having penetrated the crag, though it was sunk to 
twenty -two feet below mean-tide level. t In 1898, after a trial- 
boring which proved chalk at ninety-seven feet, a well was sunk 
by Messrs. Merryweather and Sons, at a spot selected as probably 
sufficiently far from the sea to avoid the influx of sea-water, and 
yet not too far from the village, or at too high a level. The site is 
in the valley, near Frog’s Hall, and is about seventy feet above the 
sea. Samples from the trial-boring were communicated to me by 
the well-sinkers, but were insufficient to throw much light on the
