country, one at an elevation of 50 feet and the other at 

 100 feet above sea-level. The positions of the principal 

 towns and villages, and of such railways and roads as 

 exist, are also indicated, and the north point is shown by 

 means of an arrow. 



We chartered a small steamer by means of which we 

 could explore the navigable rivers, and we were informed 

 that it would be possible to obtain small boats and 

 canoes, when we reached the shallower waters farther 

 inland. Horses, men to act as guides, and porters were 

 also available, we learned, should we need to leave the 

 main waterway, or the neighbourhood of the railways. 



Before starting we provided ourselves with the tools 

 and apparatus necessary for our work, and these included 

 a supply of picks, shovels, and geological hammers for 

 use in collection of specimens of rocks, minerals, and 

 fossils, which we might wish to bring away with us for 

 further investigation, bags for the carriage and storage 

 of these, and paint for the purpose of numbering the 

 specimens. A magnetic compass for the determination 

 of directions, a clinometer to record inclinations and the 

 dip of the strata, an aneroid barometer to record heights, 

 surveying instruments such as a level and a theodolite, 

 and good field-glasses also formed part of our equipment, 

 in case we should visit the wilder and less perfectly 

 surveyed parts of the country. 



Camp equipment, including cooking utensils and a 

 kit of carpenter's and mechanic's tools, had been provided 

 on the steamer, where there was also a microscope and 

 all the apparatus necessary for the preparation of micro- 

 scope slides, in which one of the members of our party 

 was an expert. We had also with us a palaeontologist
