which cross it more or less at right angles; but throughout 

 the rest of its extent it presents a V^old scarp to the east. On 

 my former expedition I did not obtain a good view of this 

 range, and my information led me to believe that the country 

 lying to the west consisted of a high plateau; but, as shown 

 below, this idea is incorrect. Running, as it does, almost meri- 

 dionally, it cuts directly across the courses of a number of 

 important east and west branches of tlie Rewa River, chief 

 among which are the Waimanu, Waidina, and Wainivalau, in 

 order from south to north. These emerge from the range through 

 a magnificent series of water-gaps, which are well seen on a clear 

 day from the high-level soapstone hills about Nausori. The chief 

 peaks in the range are Namaku and Wainiwaqa, respectively 

 south and north of the Waidina, Medrau sucu basaga (the Fijian 

 equivalent for "The Paps," by which name this pair of hills is 

 known to the British residents), Kororaqiqi,"^ Ucikavukavu"!" and 

 Namolaca, respectively south and north of the Wainivalau, 

 Nariko and Nacau south and north of the Wailase. Nabukelevu, 

 the "Great Yam Mound, "(spelt Buki Leva before) forms a narrow 

 spur extending for two or three miles to the east of the main 

 range. 



The true structure of the range, suggested by these water-gaps, 

 is not seen to advantage until viewed from the summit of one of 

 the mountains twelve or fifteen miles to the west. From a point 

 such as Uvuuvunidavui, the range is seen to be simpl}^ a wall of 

 rock some 2000 feet in height, and not more than three or four 

 miles in thickness at the base. Lying to the west of its central 

 and northern sections is an extensive plain which will be described 

 in detail later. On close examination the range is found to be 

 built almost entirely of verj^ coarse andesitic agglomerate. The 

 boulders in it are generally of hypersthene andesite, with a base 

 varying from glassy to pilotaxitic; Sometimes hypersthene
