sandy flat is at least two miles in width and is covered with nuTnerous 

 patches of corals and beach rock. 



The strength of the waves on the two sides of the lagoon can easily be 

 measured by the condition of the 

 islands on the opposite land rims. 

 Judging from the mass of material 

 found on the reef flats of the western 

 face of the lagoon, it is evident that 

 this material must be supplied from 

 the wearing of the reef flat on the 

 inner part of the lagoon. There are 

 not enough corals thrown up from the 

 sea face of the western side of the 

 atoll to supply the material even for 

 such a narrow land rim as exists on 

 that side of Jaluit, yet this is the source to which many writers on coral 

 reefs would look for the material to form the lee land rim.

Ailinglap (Odia or Elmore) is a triangular atoll (PI. 226, fig. 5). Its 

 eastern face is twenty-five miles in length, its western about the same, 

 and the northern nearly thirty miles in length. The principal islands 

 are on the land rim of the western face, and on the eastern face, where, 

 however, the land rim is much broken, there being numerous passages for 

 boats of considerable size through the gaps between the islands (PI. 226, 

 fig. 5). On the northern face are a large number of sand bars and islets 

 and two passages for larger vessels. The principal entrance is through 

 the southern passage north of the island of Enliebing (Pis. 168, fig. 1 ; 

 226, fig. 5). On the lagoon side of the passages we could see the same 

 sand bars and spits and flats which characterize the passes of Jaluit. This 

 lagoon is said to be from twenty to twenty-five fathoms in depth ; its
