 narrow belt awash here and there with a secondary lagoon at the northern 

 spit of this rim. 



The changes at Turadn from the conditions marked on the Admiralty 

 Chart are, as stated by Gardiner, very marked 1 and were also noted by us 

 at the time we passed by Dunikolu and anchored near Embudu, but I 

 cannot agree with Mr. Gardiner that the extensive changes observed there 

 are wholly due to solution. 2 The cyclone by which the island was struck 

 would account for the movement of a great mass of sand such as perhaps 

 formed the northern rim of Turadu in 1836. 



Boats from Turadu. 



To the northeast of Turadu rises Dunikolu, a small island with a low 

 coral sand beach and covered with a scanty vegetation. Near our anchor- 

 age stretched another, smaller faro (Velengeli), a little over a mile in 

 diameter, with an island on its western rim having somewhat the character 

 of an outer island. The wide rim of this faro enclosed a shallow lagoon

The little island of Embudu (Pis. 26, 27) to the north of our anchorage

 be little change within the lagoon.
