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
