THE EUCALYPTUS TREE. 109 



particularly noticed, however, was when we visited 

 saw-mills on the Murray, the logs were brought down 

 the river to the mill in barges, a thing that would 

 never be thought of in Canada. 



There are two very remarkable peculiarities belong- 

 ing to the leaves of these eucalyptus trees. The leaves 

 when young, say up to two or three months after 

 appearing, are of a totally different shape from the 

 older leaf. 



It has lately been discovered that in botanical 

 classification in Europe, several serious blunders have 

 been made, through a lack of knowledge, of this 

 peculiarity. 



The young leaf has no resemblance whatever to the 

 older one. When I first noticed it, in those cases 

 where a shoot had started out from the body of the 

 tree near the ground, I thought a vine or creeper of

 collected for sending home to Europe, the persons who 

 made the collections either failed to notice the differ- 

 ence in these leaves or failed to report, and the result 

 is, confusion has already arisen which can only be 

 corrected by the entire list of varieties being gone over 

 again. The young leaf, which has all the appearance 

 of being fully matured, is somewhat heart-shaped and
