lit- extension oi the wheal areas in the Wyalong district is rapidly 

 encroaching on the " Mallee," and much oi Ll has already been destroyed, the 

 hind being utilised for agricultural purposes, and i1 seems that it portions oi this 

 natural vegetation, where the "Blue Mallee" grows mosl abundantly, are no1 

 conserved for the purpose oi oil distillation, in a few years little material 

 oi E. polybractea will be procurable in the immediate neighbourhood oi

In Kangaroo Island the ' Mallee " E. cneorifolia is utilised for oil 

 production to a considerable extent, and in a paper published in 1912 by 

 Mr. H. J. Wiadrowski, an oil distiller on the island, it was shown thai 

 /:'. cneorifolia had, without any attention 01 cultivation, given a nett return of 

 £3 per acre, and with a little effort t<> improve the leaf, it would be mere 

 profitable to conserve the "Mallee" for oil, than to work the land for grain, as 

 tlie nett profits per acre would then he greater than from a 20-bushel crop oi 

 wheat at 3s. 6d. per bushel. This estimate was made at the time when 

 Eucalyptus oil was very much cheaper than it is to-day. 



(b) FROM CULTIVATED MATERIAL. 



The illustrations given previously show how readily the oil-producing 

 species renew then foliage, so thai providing the necessary areas arc conserved 

 for the purpose oi Eucalyptus oil production, abundant mate'rial for the 

 preparation oi certain classes oi oils should be assured.
