Note 197 — Chapter XIII
Reading edition
From Willingham a field road will take us, if desired, to Belsar's Hill,[197] which, besides its historical associations, is rich in the pretty crystals of selenite or gypsum. And though, as has been said, the track is now all but disused, it is still possible to follow the Conqueror's causeway to the Ouse and get ferried over to Aldreth.
