In a very interesting article on the Geology of Bermuda, published in this Magazine for September and October, 1911 (pp. 385–95 and 433–42, Pls. XVIII–XXIII), the late Rev. R. Ashington Bullen states, on p. 390, that Admiral's Cave at Spanish Point is in the Walsingham Formation. This statement is evidently due to a slip in map-reading, Admiralty Cove being the boat harbour of Admiralty House near Spanish Point, whereas the Admiral's Cave, whencethe Pœcilozonites nelsoni in the British Museum were derived, is the “cave near the calabash-tree” mentioned on p. 439. This cave owes its name to the visit of Admiral Milne, and the base of his stalagmite is still in evidence, bearing his tool marks. It is one of the largest and most remarkable of the many caves between Bailey's Bay and Tuckerstown.
