ANDREWS: LIMESTONES OF THE FIJI ISLANDS. 5 
PREFACE. 
Letter FROM Proressor T. W. EpGewortH Davin oF THE UNIVER- 
sity OF SyDNEY, New SourH Watgs, DATED Marca 15, 1899. 
Mr. E. C. Anprews, B. A., is forwarding to you by this mail for your 
information his notes, maps, sections, and photographs relating to the 
geology of the raised reefs of Fiji, with some additional notes on Tonga. 
This information he gained by personal examination of all the islands 
referred to in his report, and he and Mr. B. Sawyer, B. E. (also of Sydney 
University), who accompanied him, spared no pains in attempting to 
carry out your instructions as fully as possible. 
With the funds placed by you at his disposal, Mr. Andrews was en- 
abled to hire a cutter and a Fiji crew, and by this means he managed to 
visit most of the islands of the Lau Group and also explored Vatu Leile, 
part of Viti Levu, Taviuni, Totoya, ete. 
His method of work after landing on an island was to explore the cliff 
faces and inland terraces, measuring altitudes and distances with an 
aneroid and Abney’s level, by pacing and taking angles with a prismatic 
compass, and systematically collecting specimens by blasting and 
quarrying. 
This cliff exploration was done at first by means of a strong wooden 
box lowered over the cliffs by a rope. This method was discarded for 
the simpler one of scaling the cliffs, after the manner of the Fiji natives, 
by means of the long rope-like roots of the banyan-tree, which depended 
in some cases for over one hundred feet in length over the cliffs. 
After the sections of the cliffs had been obtained and systematic col- 
lections of specimens made, the higher slopes and inland terraces of the 
islands were explored, it frequently being necessary to cut tracks through 
the dense undergrowth for a considerable distance, in order to admit of 
the ground being traversed. 
Mr. Andrews’ short report and notes and sections speak for them- 
selves, but at the same time I should like to say a few words about 
his general conclusions. 
He finds the following formations represented in Fiji, the older being 
mentioned first : —
