Similar phenomena have been taking place during the past year, 1866, in the Bay of Santorin, situated in the island of that name, which lies to the northward of Crete. There are several islands in the bay, all apparently of volcanic origin, and one of them was thrown up about three centuries before the beginning of the Christian era. Last year their number was increased by a series of eruptions similar in their attendant circumstances to those which accompanied the upheaval of Julia. The first warnings were given on the 30th of January 1866, by low underground rumblings, and slight movements of the ground at the south end of New Kammeni, one of the formerly upheaved islands in the bay. Next day these phenomena increased in violence, and quantities of gas bubbled up from the sea. On the 1st of February, reddish flames ascended from the water, and on the 2nd there rose, out of the harbour of Voulcano, an island, which was christened "George." The volcanic agitation was prolonged during February and March--the upheaval of other two islands being the result. Whether these additional islands will continue permanently above water remains to be seen. CHAPTER VI.

On referring to the woodcut of this volcano at page 11, you will observe in what a sharp point the cone terminates, and how slender is the column of vapour at its summit. The crater at the top is comparatively small--its greatest diameter being 300, and its smallest 200 feet, while its depth is only about 100 feet. From this crater there has been no eruption since 1706, when the finest harbour in the island was destroyed. But from the side of the peak there rises a supplementary mountain named Chahorra, on the top of which there is also a crater, whence there was an eruption in 1798. So great was its violence, that masses of rock were thrown to a height of upwards of 3000 feet. In the neighbouring island of Palma there is a volcanic crater named the Great Caldera, whose depth is said to be upwards of 5000 feet.
