these may be seen near Levuka, between Vagadaca 

 and Dribi. In exposed sections, it was noticed that 

 the long stones were lying lengthwise, never perpen- 

 dicular or across one another. These imbedded stones 

 are of volcanic origin, basalt or trap. To look at the 

 rock en masse, where it lias been exposed to the 

 weather, and then at the loose disintegrated stones 

 sand, &c, on the beach, or in the bed of a river, one is 

 struck with the similarity of their appearance. This 

 agglomerate is very largely represented throughout 

 the whole of Fiji. The mountains of Ovalau (2,200 

 feet in height), are composed of it. On the north- 

 western side of Vanua Levu it forms large cliffs 

 and mountain ridges. In several of these cliffs, seams, 

 or layers of coralline limestone, 6 or 7 feet in thick- 

 ness, were seen at a few feet above sea-level. In 

 the bed of a stream at Habi, veins of a trap-like rock 

 were noticed lying between strata of agglomerate ; 

 but a doubt exists as to whether these veins are trap, 

 or limestone altered by heat. 



At the south-west side of Rabi there is a cliff of 

 sandstone which rises to a height of 20 feet above 

 the sea, and there is a similar cliff on the opposite 

 shore of Kioa island, about 7 miles distant. There is 

 also another on an island at the anchorage or roadstead 

 of Loma-Loma, but possibly it is of coralline origin. 

 The northern part of the island of Loma-Loma is com- 

 posed of coral limestone, and the southern part, near 

 the town, of agglomerate and basaltic rocks. Some, if 

 not all the islands in this part of the group, are com- 

 posed of limestone, basaltic, and agglomerate rocks. 

 On the south coast of Vanua Levu, between Savu-savu 

 and Waikava, " Fawn Harbour," the beach and adja- 

 cent islands are composed of upheaved coral limestone.
