We know that certain plants vary exceedingly in regard to their product 

 when grown in different districts, e.g., champagne grapes and lavender, and 

 we have much to learn in regard to variation in the timber of the same 

 species of tree when grown in different districts. 



For instance, Eucalyptus obliqua, to which I referred at the beginning of 

 this article, yields a product which is deservedly esteemed in parts of 

 Tasmania, but I have known the same timber condemned as being of verj 

 little value in a certain district of New South Wales. 



I have known high words and sharp controversy to arise between officials 

 of two Australian States in the discussion of the merits of a certain timber. 

 Perhaps both were right, but they were certainly arguing about the same 

 tree growing in a district which promoted its best development and one 

 which certainly did not. We must, therefore, get away from .the idea that a 

 species as we know it is always very goodi or very bad. Both Jones and 

 Brown may be right. The rose that we have imported from England at 

 great cost because experts speak so highly of it may, in our garden, turn 

 out a very disappointing thing. 



I have touched lightly and very imperfectly on a subject which is 

 obviously of very considerable importance to the Australian forester, many 

 of whose data he will have to find out himself, for he certainly will .not 

 obtain them from books.
