Abstract
The evidences of recent submergence of Bermuda are from four sources: (1) topog-raphy, (2) submerged limestone caverns, (3) buried cedars and peat bogs, and (4) existing marshes. The most convincing proof of postglacial submergence is found in the marshes on the island. The Hamilton marsh, 97.7 feet deep, gives evidence of a postglacial rise in sea-level of at least this amount. A test boring was made in this marsh to a depth of 42 feet. Five layers of woody peat were encountered, which are best interpreted as representing periods of relative stability of sea-level. They therefore show that the change was periodic and not gradual. They also offer an unusual means of determining the rate of peat accumulation and the length of postglacial time. It may be possible to correlate with their aid recent changes in level in other parts of the world.
