JALUIT. 281 



reaches of large rounded boulders of beach rock or coral conglomerate; 

 the summit of the steep beach is covered with low vegetation ; behind it 

 rise a few cocoanut trees, forming a slender line on the narrow land 

 rim of the atoll. 



The land rim of the southeastern part of Jaluit is certainly narrower 

 than that of any of the many atolls which we have seen thus far. The 

 outer reef platform itself is also narrow, judging from the position of the 

 line of breakers as we saw it when steaming north along the east coast 

 of Jaluit from the southern point. On the eastern land rim, north of the 

 south point of Jaluit, there are comparatively few cocoanut trees and 

 Pandanus, and here and there only a few large hardwood trees, standing 

 out in the narrow belt of low vegetation which surmounts the summit 

 of the high shingle beach edging the eastern face of Jaluit (PI. 161, fig. 1). 

 Considerable driftwood is also seen on the beach, consisting of logs of 

 Pandanus, of cocoanut trees, and of different kinds of hardwood. 



The coarse shingle beach of the east face becomes gradually higher as we 

 go north. The upper part of the beach resembles a stone wall (PI. 165, fig. 1) ; 

 it is steep, and consists entirely of coarse slabs of beach rock. The top of 

 the beach is exceedingly narrow, so much so that it looks like a dam ; it also 

 slopes abruptly towards the lagoon side. Steaming along the eastern coast 

 of the atoll, we could see over the eastern land lim and distinguish the 

 shoals and islands and islets, not only in the lagoon, but also across on 

 the western face of the atoll. 



As we approach the southeast entrance into Jaluit, the reef flat of the 

 northern extremity of Jaluit Island becomes somewhat wider (Pis. 164; 

 167, fig. 2), as well as the land rim which is club-shaped (PI. 228, fig. 2), 

 and forms the southern spit of the entrance into Jaluit. On the northern 

 side of the entrance, which is not more than two cable lengths wide, 

 stretches Eniibor, a low island (Pis. 161, fig. 4; 164, fig. 1), flanked like 

 the island of Jaluit with beach rock and conglomerate ledges and shingle 

 beaches; it is covered with a scanty growth of cocoanut trees and with a 

 luxuriant growth of bushes. In the southei'u extension of Eniibor lies a 

 wide spit formed by three low islands, thrown up on the northern side of 

 the entrance to the lagoon (Pis. 161, fig. 4 ; 228, fig. 2). After passing
