upon, and should under such favorable circumstances 
not a far larger export of this mercantile commodity 
be called forth. Those Eucalypts are the most pro- 
ductive of oil in their foliage which have the largest 
number of pellucid dots in their leaves; this is easily 
ascertained by viewing the leaves by transmitted 
light, when the transparent oil- glands will become 
apparent, even without the use of a magnifying lens, 
Mr. Bosisto is also a purchaser of scented flowers, 
indigenous as well as cultivated, including even the 
wattle flowers, for the extraction of delicate scents, 
under a clever process discovered by himself; and it 
is astonishing what an enormous demand for these 
perfumes exists in European markets. This may be 
a hint to any one living in or near the forests, where 
the extraction of the scent could be locally accom- 
plished from unlimited resources, with little trouble 
- and cost. 
There exists another special industry in its incip- 
ient state among us, which might be regarded as 
essentially Australian, and which also might be wide- 
ly extended: I mean the gathering of seeds of many 
kinds of Eucalyptus, and also of some Acacias and 
Casuarinas, for commercial export. No doubt the col- 
lecting of seeds is effected among the forest-trees of 
any country, and very important branches of industry 
these gatherings are, in very many localities abroad. 
But what gives to our own export trade of forest 
seeds such significance is the fact that we offer thereby 
means of raising woods with far more celerity and 
ease than would be possible through dissemination of 
trees from any other part of the globe, it being under- 
stood that the operations are instituted in climatic
