218 APPENDIX. 



the latter lias represented one continuous reef 90 miles 

 long, parallel to the shore, and in places as much as 10 miles 

 from it ; coloured pale blue. A little distance northward, we 

 have the Laughlan Islands, the reefs round which are engraved 

 in the Atlas of the Voyage of the Astrolabe, in the same man- 

 ner as round the encircled islands of the Caroline Archipelago : 

 the reef is, in parts, a mile and a half from the shore, to which 

 it does not appear to be attached ; coloured blue. At some 

 little distance from the extremity of the Louisiade lies Wells 

 Eeef, described in Gr. Hamilton's Voyage in H.M.S. Pandora 

 (p. 100) : it is said, ' We found we had got embayed in a 

 double reef, which will soon be an island.' As this statement 

 is only intelligible on the supposition of the reef being crescent 

 or horse-shoe formed, like so many other submerged annular 

 reefs, I have ventured to colour it blue. 



Saloman Archipelago. — The chart in Krusenstern's Atlas 

 shows that these islands are not encircled ; and as coral appears, 

 from the works of Surville, Bougainville, and Labillardiere, to 

 grow on their shores, this circumstance, as in the case of the 

 New Hebrides, is a presumption that they are fringed. I 

 cannot find out anything from Dentrecasteaux's Voyage, re- 

 garding the southern islands of the group, so have left them 

 uncoloured. — Malayta Island, in a rough MS. chart in the Ad- 

 miralty, has its northern shore fringed. — Tsabel Island : theN.E. 

 part of this island, as shown in the same chart, is also fringed : 

 Mendana (Burney, vol. i. p. 280), speaking of an islet adjoin- 

 ing the northern coast, says it is surrounded by reefs : the 

 shores, also, of Port Praslin appear regularly fringed. Choiseul 

 Island : parts of the shores are fringed by coral-reefs, in Bou- 

 gainville's chart of Choiseul Bay. — Bougainville Island : accord- 

 ing to Dentrecasteaux, the western shore abounds with coral- 

 reefs, and the smaller islands are said to be attached to the 

 larger ones by reefs ; all the above-mentioned islands have been 

 coloured red. — Bouha Islands : Captain Duperrey has kindly 

 informed me in a letter, that he passed close round the northern
