ELEVA riONS IN PACIFIC CORAL REGIONS. 293 



Coral has been reported to occur on the western peninsula 

 of Maui^ in some places eight hundred feet above the sea ; but 

 according to C. F. Winslow, the supposed coral does not effer- 

 vesce with acids, and therefore is not calcareous. 



There are large masses of coral rock, according to Mr, 

 Andrews, along the shores of Maui, from two to tvelve feet 

 above high water. From his descriptions, this rock appears to 

 be the reef-rock, like the raised reef of Oahu, and is probably 

 proof of an elevation of at least twelve feet. 



On page 277, it is suggested that the westernmost coral 

 islands of the Hawaian range, Ocean and Brooks's Islands, may 

 have undergone a small subsidence. Should the broken wall 

 of emerged rock turn out, on examination, to be coral reef- 

 rock, instead of the beach sand-rock, the facts would prove 

 an elevation of a few feet, instead of a subsidence. The 

 islands differ from Dean's, in having no long range of wooded 

 land on the windward side. 



/. Feejee Islands. — The proofs of an elevation of four to 

 six feet about the larger Feejee Islands, Viti Lebu and Vanua 

 Lebu, and also Ovalau, are given in the author's report on 

 this group. How far this rise affected other parts of the group 

 he was unable definitely to determine ; but as the extensive 

 barrier reefs in the eastern part of the group rarely support a 

 green islet, they rather indicate a subsidence in those parts 

 than an elevation. 



J. Islands north of the Feejees. — Home Island, WalHs, EUice, 

 Depeyster, and four islands on the track toward the Kingsmills, 

 were passed by the sloop of war Peacock of the Wilkes Ex- 

 pedition ; but from the vessel no evidences of elevation could 

 be distinguished. The first two are high islands, with barriers, 

 and the others are low coral. S. J. VVhitnell. Esq., has recently 

 stated that at Ellice Island (or Funafuti), " on the windward 

 side of the largest island of the atoll, there is a small lagoon 

 (dry at low water), shut in from the sea by a wall twenty feet 

 high, consisting of large masses of coral ; " and he regards this 

 as evidence of some elevation. Moreover, on the reef, which is 

 a narrow ledge, " compact masses of coral rock were observed
