thus we were permitted to see the various forms through which it passed, from that of a submarine volcano, with its dashing boiling stream, to that of a volcanic island ejecting its heated stones, mud, cinders, &c. This volcano forms one of the linear series of volcanoes which run in a direct line from the Culibras to Fonualei, bearing N. by E. ¼ E. and S. by W. ¼ W. magnetic. There are no less than six volcanoes in this belt, including the recent one, and all in the Friendly Islands Group, viz.: Sandfly Rock, Tofua, Kao, Wesley Rock, Late, and Fonualei. This is the order in which they stand from the recent volcano. Of these Kao is the highest, and is 5,000 feet in height, but has not been active for many years; its crater is on the N.E. side, and the shape of the island is that of a large cone. The next in height is that of Tofua, a large razor-back island, with the crater on the N.E. side. This is 2,800 feet in height, and has been slightly in action only a few months ago. The next is Late, 1,790 feet, and is still in action. Then comes Fonualei, which in some parts is about 600 feet, but has not been active for more than thirty years. The last volcano is that of Wesley Rock, which sprang up as a submarine volcano in the year 1858, and was discovered by the John Wesley; it is now about 400 feet, and occasionally very active. It is somewhat singular, and perhaps worthy of notice, that the mouth of all the craters of these volcanoes has an easterly aspect. But whether the present volcano has burst out on a part of the Culibras reef we are not prepared at present to say, the Culibras reef being marked on our chart more to the S.W. And a circumstance of considerable interest in connection with the Culibras reef is that it has fallen and risen several times during the last few years: at times a long reef being distinctly visible above the water, and at other times not a trace of it to be found; such is the statement of authorities who went with the express purpose of ascertaining and locating its position; and on one occasion, after the lapse of a year or so, the reef was found to have shifted a distance of no less than three miles. The position of the present volcano is N.N.W. from Nukualofa, 48 miles; from Huga Tonga, N.N.W. ¼ W., 14 miles; from Huga Haapai, N. by W. ¾ W., 15 miles; and its latitude and longitude, from bearings taken on board the Sandfly while abreast of the volcano, are: Latitude, 20° 21' S.; longitude, 175° 23' W. Since writing the above account, Captain Lane, of the Maile, who visited the volcano thirty-two hours after we left it, states that in his opinion the volcanic action is dying out, that the upheavals are becoming in a marked manner less in height, that the largest he saw was only about 5,000 feet high, and that the island did not appear much more than a mile in length; but others of his ship's crew give two and a-half to three and a-half
