natives never destroy a teak- tree without planting another in its 

 place, and he expresses a wish that the colonists in Australia 

 would be as careful in respect to one of our ironbarks (E. crebra), 

 which he regards as of equal value. It is rather strange that not 

 long since, I remonstrated with a gentleman for allowing his 

 overseer to ring-bark some of these very trees, for although 

 E. crebra is not the most valuable of the iron-barks, yet it is one of 

 our most durable timbers. But the changes to which I have 

 alluded are not confined to this side of the Dividing Range. Many 

 of the weeds enumerated in the subjoined list ai'e now found at 

 every sheep and cattle station in the interior, whilst it is to be 

 feared that some of the best salt-bushes, as well as the graceful 

 . myall, are doomed to extermination. When sheep feed continually 

 in the same paddocks, they eat down the salt-bushes and prevent 

 the growth of young plants, so that some stations, which formerly 

 had abundance of these plants, are now completely denuded of 

 them. The Myall also suffers from the cattle, for as the old trees 

 die off, the young ones are eaten or trodden down. In many 

 parts, useful grasses and another plants are springing up in the 

 place of those which are disappearing, but I mention the fact, 

 merely in illustration of the changes which are taking place in our 

 Flora. There was a time, when some of the orders now so largely 

 represented on this continent did not exist here, and when the 

 Flora of A ustralia was assimilated to that of Europe. And a day 

 will come most assuredly, when in the necessary process of 

 cultivation and the introduction of foreign species, many plants of 

 what are now deemed Australian types will make way for a new 

 order of tinners.
