The Burragorang Valley and The Peaks, or Yerranderie 

 Silver Mines, are conveniently reached from Camden, the 

 distance to the latter being about 42 miles westerly, while 

 the former is about halfway. Mount Werong is on the sum- 

 mit of the Great Dividing Range, some 70 miles by road 

 westerly from Camden ; so that the area discussed in this 

 paper comprises an ascending section, commencing about 20 

 miles from the coast, at an elevation of 230 feet, and gradu- 

 ally rising along the southern portion of the Blue Mountains, 

 until finally reaching an altitude of 4000 feet above sea-level. 

 Such an area affords some striking examples of the effect of 

 climate upon plant-life. In the eastern portion, coastal forms 

 are noticed, but many of these are gradually left behind as 

 the ascent is made, and cooler regions are reached, their 

 places being taken by types better adapted to withstand the 

 more rigid climatic conditions, and whose homes are on the 

 highest parts of Eastern Australia or in Tasmania. The road 

 followed is full of interest from a geological and physiographic 

 point of view, one of the finest examples of denudation in 

 the State being met with, in the deep valley of the Wollon- 

 dilly River, which has entrenched itself to a depth of over 

 1700 feet. As the vegetation is so often regulated by the 

 geological formation, the following outline is furnished of
