During the year 1919 large areas of the " Mallee Scrub " in the Wyalong 

 district were being rolled and treated in this way, so that eventually abundant 

 supplies of new leaf should be available there for oil distillation, and as the 

 stills are modern in construction and of fair size, the establishment of an 

 extensive Eucalyptus oil industry in the Wyalong district should be assured. 



The chief species of "Mallee" growing in the "Mallee Belt" in the 

 immediate neighbourhood of Wyalong, besides E. polybractea, are E. Behriana, 

 E. oleosa, and E. viridis. The constitution of the oils, as well as the yields, 

 from these Eucalypts, will be found recorded under the respective species in 

 this work.*

The above remarks in reference to E. polybractea and its associated species 

 in New South Wales, are generally applicable to the conditions which obtain 

 in the corresponding ' Mallee Belt ' in Victoria, where the Eucalyptus oil 

 distilling industry is somewhat extensively carried on, and well established. 



* Another plant of common occurrence associated with E. polybractea is the " Broombush," Melaleuca 

 uncinata. The oil of this Melaleuca is, in composition, very similar to that of " Cajuput," so well known in 

 pharmacy, and might well be considered as an Australian " Cajuput."
