PREFACE. 



The list of trees submitted is imperfect, and the following 

 explanation shows how and why it is so. 



All the illustrations are based upon the illustrations con- 

 tained in my Forest Flora of New South Wales, which is 

 still in progress, and sixty parts (ten parts to a volume), 

 dealing with individual trees,* and Containing a number of 

 Appendices treating of general forestry subjects, have now 

 appeared. 



Only a selection has been made, and if a further edition 

 be called for, additional trees will be dealt with. In its 

 incomplete state it is believed that it will form a handy 

 volume, showing' the state of our knowledge of certain trees 

 in New South Wales, and perusal of it may lead to additions 

 by forest officers and others. 



Much of the information concerning abundance and 

 distribution of individual species can only be amplified when 

 a forest survey is undertaken. 



In January, 1906, I published in the Agricultural Gazette 

 of New South Wales a. list of 521 trees indigenous to New 

 South Wales, and additional ones have been discovered 

 since then. So that the subject, in this richly-endowed 

 State, is a sufficiently vast one. Some of the trees are, 

 however, not of sufficient economic importance to be dealt 

 with in this Handbook; on the other hand, there is a for- 

 midable array of exotic trees either introduced into New 

 South Wales or considered desirable for experiment. 



J.H.M. 



*Xhe complete list (contained in Parts 1-60), as also the New South 

 Wales species dealt with in Parts 1-30 of my " Critical Revision of the 

 Genus Eucalyptus," will be foiind at p. 15.
