eruptions, preceded by volcanic action. In 1490, at the Ox Mountains,
Sligo, one occurred by which one hundred persons and numbers of cattle
were destroyed; and a volcanic eruption in May, 1788, on the hill of
Knocklade, Antrim, poured a stream of lava sixty yards wide for
thirty-nine hours, and destroyed the village of Ballyowen and all the
inhabitants, save a man and his wife and two children. ("Amer. Cyclop.,"

While we find Lisbon and Ireland, east of Atlantis, subjected to these
great earthquake shocks, the West India Islands, west of the same
centre, have been repeatedly visited in a similar manner. In 1692
Jamaica suffered from a violent earthquake. The earth opened, and great
quantities of water were cast out; many people were swallowed up in
these rents; the earth caught some of them by the middle and squeezed
them to death; the heads of others only appeared above-ground. A tract
of land near the town of Port Royal, about a thousand acres in extent,
sunk down in less than one minute, and the sea immediately rolled in.

The Azore Islands are undoubtedly the peaks of the mountains of
Atlantis. They are even yet the centre of great volcanic activity. They
have suffered severely from eruptions and earthquakes. In 1808 a volcano
rose suddenly in San Jorge to the height of 3500 feet, and burnt for six
days, desolating the entire island. In 1811 a volcano rose from the sea,
near San Miguel, creating an island 300 feet high, which was named
Sambrina, but which soon sunk beneath the sea. Similar volcanic
eruptions occurred in the Azores in 1691 and 1720.

Along a great line, a mighty fracture in the surface of the globe,
stretching north and south through the Atlantic, we find a continuous
series of active or extinct volcanoes. In Iceland we have Oerafa, Hecla,
