APPENDIX 



Note on the Stone-Axes. — Two of these polished stone-axes from a 

 collection made in Vanua Levu were selected for sections. One is light- 

 green and smooth. The other has a very different appearance, being 

 blackish and rather rough, its smooth surface having been apparently 

 lost by lying in a stream-course or in wet ground for a long period. Both, 

 however, are made of the same type of basaltic rock, the specific gravity 

 in one case being 2-93, in the other 2-97. It is an aphanitic basalt with 

 scanty olivine containing little or no residual glass and referred to genus 

 40 of the olivine-basalts. It is by no means a common type of basalt 

 in Vanua Levu, and I cannot refer it to any particular locality on account 

 of the peculiarities it presents when contrasted with rocks of the same 

 genus. The olivine is very scanty and small, and in one of the specimens 

 is represented only by pseudomorphs. The felspar-lathes vary usually 

 from '05 to '2 mm. in length, and the augite granules which are very 

 abundant are '01 or *o2 mm. in diameter. There is an occasional small 

 phenocryst of augite. The rock shows little or no alteration and cannot 

 be characterised as a greenstone. The greenish hue of one axe is due 

 to weathering ; but its extension into the internal black portion of the 

 tool is not appreciable. 



Note on the ascent of the tide up the Ndreketi River. — On July 20th 

 and 2 1 st, 1899, by observing the surface density it was ascertained that 

 at high-water the sea-water reached Navundi a mile or two below 

 Mbatiri. At low-tide it reached about half-way between Kanathangi 

 and Navundi. The moon was in her quarters. 



Note on the " talasinga " districts. — This subject will be discussed in 

 the second volume.
