198 APPENDIX. 



spoken of, Mr. F. D. Bennett informs me that the reefs, 

 on an average, extend about a quarter of a mile from the 

 beach \ the land is not very steep, and outside the reefs the 

 sea does not become deep very suddenly ; coloured red. — 

 Morotoi, I presume, is fringed : Freycinet speaks of the 

 breakers extending along the shore at a little distance from 

 it. From the chart, I believe it is fringed ; coloured red. — 

 Oahn; Freycinet, in his Hydrog. Memoir, mentions some 

 of the reefs. Mr. F. D. Bennett informs me that the shore 

 is skirted for forty or fifty miles in length. There is even 

 a harbour for ships formed by the reefs, but it is at the 

 mouth of a valley; red. — Atooi, in La Peyrouse's charts, 

 is represented as fringed by a reef, in the same manner as 

 Oahu and Morotoi ; and this, as I have been informed by 

 Mr. Ellis, on part at least of the shore, is of coral-forma- 

 tion : the reef does not leave a deep channel within ; red.— 

 O?ieehow ; Mr. Ellis believes that this island is also fringed 

 by a coral-reef: considering its close proximity to the other 

 islands, I have ventured to colour it red. I have in vain 

 consulted the works of Cook, Vancouver, La Peyrouse, 

 and Lisiansky, for any satisfactory account of the small 

 islands and reefs, which lie scattered in a N.W. line pro- 

 longed from the Sandwich group, and hence have left them 

 uncoloured, with one exception ; for I am indebted to Mr. 

 F. D. Bennett for informing me of an atoll-formed reef, in 

 lat. 28 22', long. 178 30' W., on which the Gledstanes was 

 wrecked in 1837. It is apparently of large size, and 

 extends in a N.W. and S.E. line: very few islets have been 

 formed on it The lagoon seems to be shallow; at least, 

 the deepest part which was surveyed was only three 

 fathoms. Mr. Couthouy {Remarks, p. 38) describes this 

 isld. under the name of Ocean Isld. Considerable doubts 

 should be entertained regarding the nature of a reef of this
