A Query concerning the Origin of Atolls

Abstract

HAVING recently visited and studied in some detail the coral mass of the Bermuda Islands, I have been impressed by one thing more than by anything else, namely, the fact so long known that the islands owe their present elevation almost exclusively to the action of the wind. The hills, which often rise to a height of 200–250 feet above the sea, from near their base to their summit, are made of blown coral sand, now consolidated into a more or less compact rock.
