428 AUSTRALIAN NATIVE PLANTS. 
In consequence, the botanical synonyms are very numerous, 
and this being so, the non-botanist must not be upbraided for his 
formidable list of vernacular names. These names have been 
given at some length in the following pages, as a practical know- 
ledge of Eucalyptus timbers cannot be dissociated from them, and 
surely no other genus has ever been honoured by such a number. 
The author believes that it will be found that some of the vernacu- 
lar names given have been assigned to wrong species by some 
observers, but he offers the notes as a contribution towards the 
compilation of a glossary of Eucalypt names. He would be grateful 
for corrections and criticisms. 
Mr. Bauerlen informs the author of his belief that species of 
Eucalyptus can be unerringly determined by means of the leaf- 
galls. He made the observation at first very diffidently, but 
subsequent experience seems to bear out his view to some extent. 
The author is aware that the late Mr. W. Sharp Macleay long ago 
used to favour a somewhat similar idea. In the Technological 
Museum the variety of Eucalyptus galls is great. The subject is 
interesting, but much more evidence requires to be collected 
before an authoritative opinion can be pronounced. 
Mr. Henry Deane informs the author that in the Cooma 
district, New South Wales, Eucalyptus timber which assumes a 
white or hoary appearance on the outside, is considered to be 
durable. 
Wherever he could, the author has quoted the opinions of 
unbiassed people outside the colonies. The opinions of Mr. Laslett, 
late Timber Inspector to the Admiralty, are, on the whole, not 
favourable to Eucalyptus timbers. But much of the ‘ shake” 
noticed in the large logs, and to which all timber of this kind 
seems liable, appears to be preventable wholly, or in part, by 
proper seasoning, careful felling, so that the trees do not come 
down with a crash, and rejection of trees of the largest size. 
The experiments of Mr. Allen Ransome on samples of timber 
sent to the Colonial and Indian Exhibition of 1886 are more 
favourable, but it is a pity that the samples at his disposal were so 
few and so small, and, consequently, his reports so brief.
