LIKIEB. 309 



The island of Rongerik to the south of Emegua consists of large masses 

 of flat beach rock, thrown up like a shingle beach, and partly overwhelmed 

 by sand dunes blown over from the flats on the lagoon side. Usually the 

 islands of Rongelab are covered with sand at the two extremities, and it is 

 only in the centre that beach rock slabs and coral conglomerate crop out. 

 The small islands on the west face of Likieb are narrow, and have a scanty 

 capping of low scrub. The little island of Bokelan has a few trees on it ; 

 at its extremities are high sand beaches ; beach rock conglomerate crops 

 out only over the central part of the western face, having been over- 

 whelmed at the extremities of the island by the sand blown over from 

 the lagoon side. 



The northwest face of Kapenor (PL 174, fig. 1) is flanked by a steep 

 sand beach, from twelve to fourteen feet in height, capped by a rich 

 belt of low vegetation. An occasional boulder of beach rock conglomerate 

 crops out on the base of the beach at the level of about three-quarters tide. 

 Sand from the lagoon side has overwhelmed, to a certain extent, the reef 

 platform. From the west point of Kapenor extends a high black shingle 

 beach ; it crops out again on the flat of the lagoon side ; the beach 

 rock conglomerate also crops out on the reef flat. The two extremities 

 of the island of Kapenor and the islands and islets to the north are 

 covered with sand, blown over from the lagoon flats ; the central part of 

 Kapenor, immediately above the base of the beach, is covered in part by 

 shingle, in part by sand, the beach rock cropping out only irregularly. The 

 little islands of Rongerik, Rongelab, and Bokelan all have high sand beaches ; 

 sand tongues have been driven, from the beaches of the lagoon face, into 

 the belt of vegetation directly across the island. Scattered among the 

 stretches of beach rock conglomerate are masses of coral thrown up from 

 the reef flat. On the east side of Kapenor a bight has been formed on 

 the miniature horn of the northern flat of the island. This bight is 

 separated from the lagoon and the sea exactly as is the northwestern 

 horn of Likieb ; it is gradually filling by the formation of bars on the reef 

 flat connecting the weather and the lee sides. In this case the flat only 

 extends from the weather side of the lagoon to the lee face of the western 

 rim, but the process is the .same. From Kapenor a reef flat extends to the
