PHYSICAL MAP OP AUSTRALIA 



The very small area in Australia having an elevation of more than two thousand feet 

 is clearly shown. Perhaps more striking even than this is the fact that, except for a very 

 tiny area lying back of the coast in the southeast corner, there are no elevations exceeding 

 four thousand feet. 



and that geologic history is a common 

 subject of study in schools ; but I some- 

 times wonder why the kangaroo and emu 

 occupy the commonwealth coat of arms to 

 the exclusion of the gums and the wattle, 

 about which the finer sentiments of Aus- 

 tralia center. 



Australia's national trpl 



Australia is the home of the wonderful 

 eucalyptus, a tree about which a fair-sized 

 library of books and pamphlets has been 

 written, without exhausting the subject. 

 For geological ages the eucalypts have 

 remained undisturbed in this "biological 

 backwater," and, spreading over the con- 

 tinent, have adapted themselves to many 



varieties of soil and climate and elevation. 

 About 300 species have already been dis- 

 covered in the small part of the continent 

 explored by botanists. 



It is a hopeless task for the tourist to 

 gain an acquaintance with this national 

 tree. As we passed through woods and 

 open spaces, seeing trees of widely differ- 

 ent aspect — different in form and method 

 of branching, different in color and kind 

 of bark, different in shape and size and 

 color of leaf, some oozing gum, others 

 clean and dry — it was disconcerting to be 

 quietly told by our botanist-guide that this 

 surprising array of trees "includes only 

 varieties of the genus eucalyptus." It is 

 as if the traveler in New England were
