Note 85b — Chapter VII · GEOLOGICAL NOTES.
Reading edition
We may further add that it is at the junction of the Northampton sand with the underlying lias, that we find numerous springs in other parts of the county; as at Navanby, Waddington, Lincoln, Blyborough, Kirton, and several other places. The Government “Geological Survey Memoir” for the country around Lincoln (p. 208) agrees in saying that the Woodhall water comes from the “inferior oolite” which comprises the Northampton sands.
