140 A RESEARCH ON THE EUCALYPTS OF TASMANIA 



The economics of one at least of Tasmania's Eucalypts 

 are world-wide, those of E. globulus, and probably there 

 has been more literature published in connection with this 

 species than any other belonging to the whole genus. 



In the United States of America it is more cultivated 

 than any other, thousands of acres being planted with it 

 as a source of timber-supply ; but its essential oil has made 

 its name better known than its wood. 



However, this research now shows that Tasmania pos- 

 sesses other trees yielding oil of equal therapeutic value, 

 and what is of quite as much importance, posses several 

 other trees yielding phellandrene oils, now so extensively 

 used in mineral separation.

 lows, on a cortical classification : —
