The principal islands of the archipelago are called St. David, Somerset, Hamilton, and St. George.  The latter has a free port, and the town of the same name is also the capital of the group.

The largest of these isles is not more than seventeen miles long and five wide.  Leaving out the medium-sized ones, there remains but an agglomeration of islets and reefs scattered over an area of twelve square leagues.

Although the climate of Bermuda is very healthy, very salubrious, the isles are nevertheless frightfully beaten by the heavy winter tempests of the Atlantic, and their approach by navigators presents certain difficulties.

What the archipelago especially lacks are rivers and rios.  However, as abundant rains fall frequently, this drawback is got over by the inhabitants, who treasure up the heaven-sent water for household and agricultural purposes.  This has necessitated the construction of vast cisterns which the downfalls keep filled.  These works of engineering skill justly merit the admiration they receive and do honor to the genius of man.

It was in connection with the setting up of these cisterns that I made the trip, as well as out of curiosity to inspect the fine works.

I obtained from the company of which I was the engineer in New Jersey a vacation of several weeks, and embarked at New York for the Bermudas.

While I was staying on Hamilton Island, in the vast port of Southampton, an event occurred of great interest to geologists.

One day a whole flotilla of fishers, men, women and children, entered Southampton Harbor.  For fifty years these families had lived on the east coast of Back Cup, where they had erected log-cabins and houses of stone.  Their position for carrying on their industry was an exceptionally favorable one, for the waters teem with fish all the year round, and in March and April whales abound.

Nothing had hitherto occurred to disturb their tranquil existence.  They were quite contented with their rough lot, which was rendered less onerous by the facility of communication with Hamilton and St. George.  Their solid barks took cargoes of fish there, which they exchanged for the necessities of life.

Why had they thus abandoned the islet with the intention, as it pretty soon appeared, of never returning to it?  The reason turned out to be that they no longer considered themselves in safety there.

A couple of months previously they had been at first surprised, then alarmed, by several distinct detonations that appeared to have taken place in the interior of the mountain.  At the same time smoke and flames issued from the summit—­or the bottom of the reversed cup, if you like.  Now no one had ever suspected that the islet was of volcanic origin, or that there was a crater at the top, no one having been able to climb its sides.  Now, however, there could be no possible doubt that the mountain was an ancient volcano that had suddenly become active again and threatened the village with destruction.
