ELEVATIONS IN PACIFIC CORAL REGIONS. 295 



De Haven, who was engaged in the survey of the reef. We 

 were told, also, that Kuria and Nononti were similar in having 

 the reef elevated, though to a less extent. It would hence 

 appear that the elevations in the group increase to the north- 

 ward. 



Alarakei, to the north of Apaiang, is wooded throughout. 

 We sailed around it without landing, and can only say that it 

 has probably been uplifted like the islands south. Makw, the 

 northernmost island, presented in the distant view no certain 

 evidence of elevation. 



The elevation of the Kingsmills accounts for the long con- 

 tinuity of the wooded lines of land, an unusual fact, considering 

 the size of the islands. The amount of fresh water obtained 

 from springs is also uncommon (p. 241). 



/. The Marshall diud Carolme Islands. — The facts in reference 

 to the islands of these groups are not yet fully known. The 

 very small amount of wooded land on the Pescadores inclines 

 us to suspect rather a subsidence than an elevation ; and the 

 same fact might be gathered, with regard to some of the islands 

 south, from the charts of Kotzebue and Kruesenstern. But 

 McAskill's, as stated on page 261, is an elevated coral island, 

 having a height of 100 feet. 



;;/. Ladroties. — The seventeen islands which constitute this 

 group may all have undergone elevations within a recent period, 

 but owing to the absence of cora! from the northern, we have 

 evidence only with regard to the more southern. 



Guam, according to Quoy and Gaymard, has coral rock 

 upon its hills more than six hundred feet (one hundred toises) 

 above the sea. 



Rota, the next island north, afforded these authors similar 

 facts, indicating the same amount of elevation. 



n. Pelews and neighbouring Islands. — The island Feis, three 

 hundred miles south-west of Guam, is stated by Darwin, on the 

 authority of Lutke, to be of coral, and ninety feet high. 

 Mackenzie Island, seventy-five miles south of Feis, is a low 

 atoll, as ascertained by the Expedition. No evidences of ele- 

 vation are known to occur at the Pelews.
