The existence of an outlying tract of Chalk in the parish of Widworthy, near Honiton, has been known for many years, but no description of it has ever been published, although it is the most westerly inland tract of Chalk in England: the only more westerly patches being those on the coast. It was known to Dr. Fitton, who mentions the occurrence of a particular stone called grizzle by the quarrymen ‘in a large pit or quarry at the bottom of the Chalk, near Sutton and Widworthy,’ remarking also that ‘it contains green particles, and does not burn to lime.’ The outlier of Chalk is marked on De la Beche's geological map published by the Geological Survey in 1845. In 1874 the district was re-surveyed by Mr. Ussher for a new edition of the Survey map, but he found that the quarry referred to was disused and overgrown. My object in visiting the locality last year was to ascertain whether the succession of beds was similar to that on the coast, in which case the Chalk would be Middle Chalk (Turonian), and the Lower Chalk would be represented by quartziferous limestone and calcareous sandstone; or whether it included anything like the more ordinary kind of Lower Chalk, such as occurs at Membury and Chard.
