having a north- westerly course, viz., the Ba river. 

 The slopes on the south-east side of the main water- 

 shed are well wooded, and receive the south -cast trade 

 wind directly from the ocean. On them the clouds 

 of vapour brought by this wind, break, and pour out 

 ram like a deluge. The country on the N."W. side of 

 the watershed is denuded of trees, excepting a few 

 small patches of forest on the summits of some of the 

 mountains and on the steep rocky sides of a few 

 ravines. The ascending land and mountains on the 

 S.E. side of the watershed are the chief cause of the 

 descending slopes and hills on the N.W. side getting 

 little rain, during the time (6 or 7 months each year) 

 that the S.E. winds prevail in the group. Also, the 

 generally unwooded state of the country on the N.W. 

 side' largely contributes to the same effect. On the 

 other hand, when north-westerly winds predominate the 

 N.W. side is the wettest, at least its high-lying lands 

 and its best wooded parts are so. 



Voma, in the vicinity of Namosi, is supposed to be 

 the highest mountain in these islands ; but there arc 

 several lofty peaks in the ranges near Nadrau that 

 challenge its supremacy. To give a description of the 

 mountain ranges in Viti Levu would be an almost 

 impossible task, they are so numerous, and they divide 

 and subdivide, and connect in a manner that seems to 

 be perfect confusion. The watershed just described, 

 will give an indication of how the land lies in a 

 general way. There is, however, a singular feature 

 connected with this main watershed, which deserves 

 notice. The Siga Toka flows for a long distance in a 

 deep valley, cut down as it were, through the centre 

 of the watershed, and dividing the eastern from the 

 western slope. At Nadrau this valley contracts into 

 a gorge about 800 feet in depth, and so narrow and
