62 FOREST CULTURE AND 
Similar substances from various melaleucas might be 
added. Originally, an opinion was entertained that 
all the eucalyptus oils have great resemblance to each 
other; such, however, proved not to be the case when 
it came to accurate experimental tests. Thus, for 
instance, the oil which in such rich percentage is 
obtained from Eucalyptus amygdalina, though excel- 
lent for diluting the most delicate essential oils, is of 
far less value as a solvent for resins in the fabrication 
of select varnishes. For this latter purpose the oil 
of one of the dwarf Eucalypts forming the Mallee 
Scrub, a species to which I gave, on account of its 
abundance of oil, the name ‘‘Eucalyptus oleosa”’ 
nearly a quarter of a century ago, proved far the best. 
It is this Mallee oil which now is coming into exten- 
sive adaptations for dissolving amber, Kauri resin, 
and various kinds of copal. Mr. Bosisto’s researches 
are recorded in the volume of the Royal Society of 
Victoria for 1863; Mr. Osborne’s in the Jurors’ 
Reports of the Exhibition of 1862. For alluding so 
far to this oil distillation I have a special object in 
view. I wish to see it adopted near and far as a col- 
lateral forest industry, now that the way for the ready 
sale of this product is so far paved. The patentee is 
willing to license any person to adopt his process, and 
he is also ready to purchase the oil at a price which 
will prove remunerative to the producer. If it is now 
considered how inexhaustible a material for this oil 
industry is everywhere accessible in our ranges, how 
readily it is obtainable, particularly at saw-mills and 
at splitters’ establishments, and how easily the pro- 
cess of the distillation can be performed, it would be 
really surprising should these facilities not be seized
