The "Peppermint" species, in the majoritj ol cases, product' phellandrene 

 oils together with piperitone, or cineol-phellandrene oils, and occasionally 

 cineol oils without phellandrene. They grow most abundantly on the mountain 

 ranges, and in country that probably will not be required for agricultural 

 purposes, so that beyond the work needed for concentration in these areas, no 

 further cultivation, with these species, need be considered. 



With the perfumery oil-producing species, and to a lesser extent those 

 yielding the richer cineol oils, the case is different, and it seems to us that the 

 time is approaching when it will be necessary for certain species to be cultivated 

 lor their oils, if the increasing demands for these products is to be mel 

 in a satisfactory manner. Unfortunately the idea of systematically cultivating 

 Australian plants for the production of their economics appears to have little 

 interest for the average Australian, the tendency being rather towards the 

 destruction of the native vegetation. The eventual shortage of supplies seems 

 to have little influence, and this is evidenced in several directions. 



So far little has been done in Australia in the direction of cultivation, and 

 ronsequently accurate data in this connection, particularly with the oil- 

 producing species, are limited. 



EUCALYPTUS MACARTHURI. 



Some evidence, however, is available, as a few acres were planted in 



September, 1911, at Emerald, Victoria, by Messrs. J. Bosisto & Co., with the 



eraniol and geranyl-acetate producing species, E. Macarthuri. The result from 



this effort was quite satisfactory, so much so, that recently a considerably 



extended area has been planted with the same species in the same locality.

Fmerald, Victoria. 



An illustration of this first plantation of E. Macarthuri is here given 

 (Plate xcixT, as being of interest in this connection. The still for the production 



of the oil is seen in the foreground.
