MULAKU. 121 



to the north of Kureli Faro, they appear like a series of great parallel 

 furrows thrown up near the outer edge of the rim. Similar ledges of 

 boulders and lines of shingle extend from Kureli to Kolufuri, the southern- 

 most point of Mulaku. 



Fine patches of corals grow on the inner rim flats, and on the sea slope 

 of the outer faces corals must also grow in great abundance, judging 

 from their extension eastward over the outer rim Mats and from the mass of 

 coral boulders and coral shingle thrown up as dikes on the sea faces of the 

 faros along the whole western face of Mulaku. The outer edge of the reef 

 flats are discolored by the dark patches of growing corals stretching to the 

 eastward across the outer rims of the faros. 



Kureli Island is on the extremity of the southern faro of the west face of 

 Mulaku, set back a short distance from the western edge of the rim reef flat, 

 flanked by a belt of rough, angular coral boulders forming a low wall of 

 pitted, honeycombed, and undercut masses passing towards the inner face, 

 first into coarse coral shingle and then into coral sand on the east face. 

 The southern face of Kureli Faro (PI. 65, fig. 2) is edged by a similar wall 

 best seen off the west face of the island itself, indicating a former higher 

 level of Kureli. 



We also examined the northern half of the west face of Mulaku ; it is 

 bounded by a number of small faros of irregular outline, separated by deep 

 passes. The faces of the passes are usually indicated by heaps of shingle 

 or small boulders or accumulations of sand. Along the sea faces of the 

 faros, shingle or sand jetties project to the eastward. 



North of Tuvaru there are no islets on the faros of the west face except 

 on the northern faro, near the northwest horn of Mulaku, where rises a 

 small island flanked by a coral sand beach and covered with low vege- 

 tation. Neither this island nor the small wooded island we saw on a sand 

 bank to the eastward are indicated on the charts of 1836 ; they have both 

 been formed since that date. The southern extension of the northwestern 

 horn of Mulaku is a narrow reef flat, the western edge of which is crowded 

 with flourishing patches of corals. The western face of the faro to the 

 south is also edged with coral patches.
