Pickering's Peak (Koroba), flows east by south, and 

 joins the main river at na Tua-tua-coka. The Siga 

 Toka is perhaps the longest river in Fiji ; but its 

 course lies at the bottom of a deep valley, which 

 narrows in some places to a perfect gorge or chasm, 

 at the top of whieh, and almost within a stone-cast 

 of its channel, some other rivers (notably the Wai 

 ni Mala, &c.,), have their sources. 



The Ba river is formed of two branches, one of 

 which rises in the mountains behind Raki-Raki and 

 flows for some distance in a south-westerly direction, 

 then turns and flows in a north-westerly direction to 

 the sea. The other branch rises on the top of the 

 gorge overlooking Nadrau on the Siga Toka, flows 

 first to north-west, then turns suddenly to north-east, 

 and joins the main stream about 25 miles from its 

 mouth. 



The Wai Delice rises in a ridge of mountains which 

 stretches along the coast with diminishing elevation, 

 from Namena to Viti Levu bay. The course of the 

 river, at first is in a southerly direction, then taking 

 a turn to the eastward, it reaches the sea near Verata 

 point. The Nadi river, which is of second or third rate 

 importance and size, rises between the right or main 

 branch of the Siga Toka and the left branch of the 

 Ba river, and flows westward into llaurau bay. On 

 its left it receives several small rivulets from the 

 northern slope of Koroba mountain.

 and rims almost due north through the centre of the 

 island to the Nananu islands at its most northerly 

 point. The most important slopes are towards the 

 south-easl and south-west, only one river of any size
