PACIFIC OCEAN. 203 



as it lies so near Atiu, it has been unavoidably coloured red.— 

 Rarotonga : Mr. Williams informs me that this is a lofty 

 basaltic island, with an attached reef; coloured red. — There are 

 three other islands, Rourouti, Roxburgh, and Hull, of which I 

 have not been able to obtain any account, and have left them 

 uncoloured. Hull Island, in the French chart, is written with 

 small letters as being low. — Mangaia : height about 300 feet ; 

 'the surrounding reef joins the shore ' (Williams's Narrative, 

 p. 18) ; coloured red. — Rimetara : Mr. Williams informs me 

 that the reef is rather close to the shore ; but, from informa- 

 tion given me by Mr. Ellis, the reef does not appear to be 

 quite so closely attached to it as in the foregoing cases : the 

 island is about 300 feet high (Naut. Mag. 1839, p. 738) ; 

 coloured red. — Rurutu : Mr. Williams and Mr. Ellis inform 

 me that this island has an attached reef; coloured red. It is 

 described by Cook under the name of Oheteroa : he says it is 

 not surrounded like the neighbouring islands, by a reef; but he 

 must mean a distant reef. — Toubouai : in Cook's chart (Second 

 Voyage, vol. ii. p. 2) the reef is laid down in a part at the dis- 

 tance of one mile, and in another part at the distance of two 

 miles from the shore ; Mr. Ellis (Polynes. Ees. vol. iii. p. 381) 

 says the low land round the base of the island is very extensive ; 

 and this gentleman informs me that the water within the 

 reef appears deep ; coloured blue. — Raivaivai, or Vivitao : 

 Mr. Williams informs me that the reef is here distant from 

 the shore ; Mr. Ellis, however, says that this is certainly 

 not the case on one side of the island ; and he believes that 

 the water within the reef is not deep ; hence I have left it 

 uncoloured. — Lancaster Eeef, described in Naut. Mag. 1833 

 (p. 693), as an extensive crescent-formed coral-reef, has not 

 been coloured. — Rapa, or Oparree : from the accounts given 

 of it by Ellis and Vancouver, there does not appear to be 

 any reef — /. de Bass is an adjoining island, of which I can- 

 not find any account. — Kemin Island : Krusenstern seems hardly 

 to know its position, and gives no further particulars.
