EUCALYPTUS TREES. 87 
and to reduce all these inquiries to a sound basis by 
assigning to any species that position in the phyto- 
logic system by which it can be recognized by any one 
in any part of the globe. When the wants of phy- 
toglaphy are satisfied we have to call to aid chemistry, 
therapy, geology, culture, microscoptic investigation, 
pictorial art, and other branches of knowledge, to 
illustrate the respective value of the species, and the 
degree of its importance to any particular community. 
But in the discussions of one evening we can do no 
more than to touch succinctly only on a few of those 
vegetable objects most promising to our own colony 
for introduction, or most accessible among those indig- 
enous here; we may glance on them, also, with a 
view of learning how their elucidation might practi- 
cally be pursued, and the knowledge thus gained be 
diffused. To aid in the latter aim the phytologic sec- 
tion in the Industrial Museum is to be established ; 
of the requirements of this section I shall say a few 
passing words. 
The products and educts of the vegetable world are 
immense ; any display of them in the order of sci- 
ence, as intended for this museum, must carry with 
it a permanency of impressive instruction which any 
other modes of teaching, sure to be more ephemerous, 
fail to convey. But these efforts at diffusing knowl- 
edge should be seconded by means not inadequate to 
a great object, and should be worthy of the dignity 
and name of this rising country. Who would not 
like to see the best woods of every country stored up 
here in instructive samples—nearly a thousand kinds 
alone to choose from, as far as our continent is con- 
cerned ? Who would not wish to have here at hand
