V. " Account of a new Volcanic Island in the Pacific Ocean." 

 By Wilfred Rowell, H.B.M. Consul in Samoa. In a 

 letter to the Hydrographer of the Admiralty. Received 

 January 17, 1886. 



Hydrographic Department, Admiralty, S.W., 

 Sir, 16th January, 1886. 



I have the hononr to forward to yon a photograph and a copy of 

 a letter received from H.M. Consnl at Samoa, relating to a volcanic 

 island recently formed by a submarine volcano* in the vicinity of the 

 Friendly Gronp in the Pacific Ocean, which I think may be of interest 

 to the Royal Society. 



I also forward a chart of the locality showing the position of the 

 new island. 



It is unfortunate that, as the hydrographical knowledge of the 

 vicinity is very imperfect, no information exists as to the depths from 

 which this island has pushed its way.

H.B.M. Consulate, Samoa, 

 Sir, November 21st, 1885. 



I have the honour to report that whilst on a passage from the 

 "Friendly" Islands to the "Navigators" Islands, on board the steam 

 ship " Janet Nicoll," we observed a newly-risen volcanic island. I was 

 informed in "Tongatabu" that the eruption was first remarked from 

 that island (a distance of over 40 miles) on Tuesday, 13th of October. 

 We passed it on Sunday, the 8th of November, at a distance of about 

 H miles. 



The following will be the approximate position by compass bear- 

 ings :— 



Peak of "Kao" Island over centre of "Tefoa" Island, north by 

 east. 



West end of " Honga Tonga" Island, south by east. 

 Centre of crater from ship west 1^ miles. 



The island appeared to be about two miles in length north by west 

 and south by east, of about 200 feet in height, having a reef on the
