ELEVATIONS IN PACIFIC CORAL REGIONS. 291 



Penrhyn's Isla/id, near 9° S. and 157' W., has a length 

 of nine miles, and an extensive lagoon with a boat entrance 

 into it. According to Captain Ringgold of the Wilkes Ex- 

 pedition, it has a height of fifty feet, which, if correct, would 

 indicate an elevation of full thirty-five feet. The north-west 

 side is, throughout, a cocoanut grove. 



Flint's Island, in 11° 26' S., and 151° 48' W., is only a 

 mile and a half long, but is thickly wooded, according to 

 Captain Ringgold, which is unusual for so small an island 



Staver's Island^ in 10° 5' S., and 152° 22^' W., is only 

 half a mile across, and yet is well wooded. Both of these 

 islands were passed by Captain Ringgold, but he does not 

 state the height. — (Wilkes's Narr., iv. 277.) 



Baker's Island, 0° 13' N., 176° 22' W., is one mile long 

 and two-thirds of a mile wide. The greatest height, according 

 to J. D. Hague, is twenty-two feet, " showing some evidences 

 of elevation." (See further, p. 247.) It has probably been 

 elevated at least six feet. 



Howlands Island, 0° 51' N., and 176° 32' W., is about 

 forty miles north of Baker's. It is about one and half 

 miles long, and half a mile wide. The highest point, ac- 

 cording to Hague, is ten or twelve feet above high-tide level ; 

 which is evidence of but little if any elevation. It is a guano 

 island, like Baker's. 



McKeafis Island, of the Phoenix Group (like Phoenix, En- 

 derbury, and Birnie's), in 3° 35' S., 174° 17' W., is a low 

 island, according to Hague, circular in form, one-quarter of a 

 mile in diameter, but less elevated than Jarvis's Island. It has 

 a lagoon depression, in which there is a gypsum and guano 

 deposit ; at high tides the guano is sometimes two feet under 

 water. Phoenix's Island, near McKean's, 3° 40' S., 170° 52' 

 W., is less than half a mile in diameter, and the border is only 

 eight or ten feet high ; so that there is no evidence in the 

 height of an elevation. It is also a guano island. 



Enderbury's, in 3° 8' S., 174° 14' W., is eighteen feet high. 

 It has probably experienced some elevation. But the height 

 of the tides is such in the seas as to give the beach and drift
