On the 18th of July the captain of the Sicilian ship discovered that an island had arisen out of the sea at the spot whence the appearances before described had proceeded. It had already attained a height of nearly twelve feet, and had in its centre a crater, which vomited forth immense jets of steam, along with ashes, cinders, stones, &c. The water which boiled in this crater was reddish, and the cinders, which covered the sea all round the island, were of a chocolate colour. The island subsequently attained a height of upwards of 90 feet at its highest point, and a circumference of about three-quarters of a mile. A channel of communication was also opened between the sea and the interior of the crater, which had a diameter of about 650 feet. The vapours and other matters thrown up from the mouth of the volcano formed a luminous column upwards of 200 feet in height. On the 29th of September it was visited by the French gentleman who gave it the name of Julia, and it then presented the appearance which we have sketched. He landed with a party and proceeded to examine the crater, in which he found a circular basin filled with reddish water, almost boiling hot, and fresh. This basin was nearly 200 feet in diameter. There rose from the water bubbles of gas, which made it appear as if it were boiling. The water was not quite at the boiling point, however, yet the bubbles of gas were sufficiently hot to burn the fingers. [Illustration: Crater of Julia, or Graham's Island.] These bubbles rose from a great depth, and each, on bursting, which it did with a feeble report, threw out sand and cinders. At a short distance from the crater there rose sulphurous vapours, which deposited sulphur and salt. The loose dust and ashes forming the soil of the island were hot, and walking on them was difficult. The foregoing woodcut will give you an idea of the appearance which the crater presented to those visitors. In the following month of October nothing remained of this wonderful island but a hillock of sand and cinders; and at the end of six months it had quite vanished. Soundings taken a few years ago show ten feet of water over the spot, so that, although the island has disappeared, there is still a shoal left behind. This temporary volcano is best known in England under the name of Graham's Island; so called after an English naval officer of that name, who was the first to set foot on it, and who planted upon it the English flag, so claiming it for his sovereign. The Sicilians allege this to be the reason why it disappeared so soon--that it was in a hurry to escape from under the English yoke.
