222 APPENDIX. 



visited by Lutke, is described and figured by Mr. Bennett 

 (United Service Journal, Jan. 1832) as an atoll. All the 

 before-mentioned islands have been coloured blue. It must, 

 however, be stated that between Nalan and Pouynipete, the 

 three McAskill Islands rise to a height of from 40 to 100 feet, 

 and consist, according to Dana (Corals and Coral Islands, 

 p. 306), of coral-rock; whether they are encircled or fringed by 

 coral-reefs does not seem to be known. 



"Western part of the Caroline Archipelago. — Fais 

 Island is 90 feet high, and is surrounded, as I have been in- 

 formed by Admiral Lutke, by a narrow reef of living coral, 

 of which the broadest part, as represented in the charts, is 

 only 150 yards ; coloured red. — Philip Island, I believe, is 

 low ; but Hunter, in his Historical Journal, gives no clear 

 account of it ; uncoloured. Elivi: from the manner in which 

 the islets on the reefs are engraved in the Atlas of the Astro- 

 labels Voyage, I should have thought they were above the 

 ordinary height ; but Admiral Lutke assures me that this is 

 not the case: they form a regular atoll; coloured blue. Gouap 

 (Eap of Chamisso) is a high island with a reef (see Chart in 

 Voyage of Astrolabe) in most parts more than a mile distant 

 from the shore, and two miles in one part. Captain D'Urville 

 thinks that there would be anchorage (Hydrog. Descript. 

 Astrolabe Voyage, p. 436) for ships within the reef, if a 

 passage could be found ; coloured pale blue. — Goulou, from 

 the chart in the Astrolabe's atlas, appears to be an atoll : 

 D'Urville (Hydrog. Descript. p. 437) speaks of low islets on 

 the reef; coloured dark blue. 



Pelew Islands. — Krusenstern speaks of some of the islands 

 being mountainous ; the reefs are distant from the shore, and 

 there are spaces within them, not opposite to any valley, from 

 10 to 15 fathoms deep. According to a MS. chart of the 

 group by Lieut. Elmer in the Admiralty, there is a large space 

 within the reef with deepish water : although the high land 

 does not hold a central position with respect to the reefs, as is
