I'm reading the book *The Map that Changed the World* by Simon Winchester and therein is mentioned the book *Natural History of the Earth* (by John Woodward in 1695) "which revealed his fascination for 'speluncae, grottoes and wells' and his unshakable belief that 'the circumstances of these things in remote countries were very much the same as those of ours here'."
I would not be surprised if a few of you either have read this 300-year old book by Woodward or perhaps have it in your library. In 1695 there was speculation about cavers, caves and pits elsewhere in the world. Terry Plemons
