CHANGES OF LEVEL. 407 
Beveridge Reef, a hundred miles southeast of Savage, is low coral. 
Samoan Istanps.—No satisfactory evidences of elevation were de- 
tected about these islands. 
ScaTTERED Isianps, north of Samoa. 
These islands are all of coral, and several indicate an elevation of 
one to six feet. On account of the high tides, (4 to 6 feet,) the sea 
may give a height of ten or twelve feet to the land. 
Swain’s, near latitude 11° S., is fifteen to eighteen feet above the 
sea, where highest, and the beach is ten to twelve feet high. Itisa 
small island, with a depression at centre, but no lagoon. The height 
proves an elevation of three to siz feet. 
Fakaafo, ninety miles to the north, is fifteen feet high. The coral 
reef rock is raised in some places three feet above the present level of 
the platform. Elevation at least three feet. 
Nukunono, or Duke of Clarence, near Fakaafo, was seen only from 
shipboard. 
Oatafu, or Duke of York’s, is in some parts fourteen feet high. Ele- 
vation ¢wo or three feet. 
Enderby’s and Birnie’s, still farther north, are twelve feet high. 
Judging from the double slope of the beach on Enderby, this island 
may have undergone an elevation of éwo feet, the height of the upper 
slope; yet we think it doubtful. 
Gardner’s, Hull's, Sydney and Newmarket were visited by the Expe- 
dition, but no satisfactory evidences of elevation on the first three 
were observed. The last is stated by Captain Wilkes to be dventy- 
jive feet in height. 
FEEJEE Istanps.—The proofs of an elevation of four to six feet 
about the larger Feejee Islands, Viti Lebu and Vanua Lebu, and also 
Ovalau, have been given in our report on this group, on page 351. 
How far this rise affected other parts of the group, | have been 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. 
IsLANDS NORTH OF THE I[*EEJEES.—Horne Island, Wallis, Ellice, 
Depeyster, and four islands on the track towards the Kingsmills, were 
passed by the Peacock ; but from the vessel, no evidences of elevation 
could be distinguished. The first two are high islands, with bar- 
riers, and the others are low coral. Rotuma, (177° 15’ E., and 12° 
30’ N.,) is another high island, to the west of Wallis’s. It has 
encircling reefs, but we know nothing as to its changes of level.
