Cyril will no doubt dwell in his talk on that difference between the Triassic Coast, where Budleigh Salterton is situated, and the Jurassic Coast which makes up much of Dorset's shoreline.
It's a difference which has been staring us in the face for centuries of course. Just after I'd posted my promotional piece for the Museum I spotted via a Google news alert the mention of a 19th century versifier's view which Cyril might like to quote for his talk.
This is a certain R.H.D. Barham, son of the author of The Ingoldsby Legends, who retired to live in Dawlish and died there in 1886.
In his poem The Monk of Haldon he contrasts East Devon's Triassic Coast, looking "like anchovy paste spread upon toast" with the way in which the Jurassic Coast of "neighbouring Dorset gleams white as a ghost."
