EUCALYPTUS TREES. 581 
state garden here? About 50 of these were rendered 
known to science by Melbourne researches. Imagine 
the glory of some of these trees, when—as in the in- 
stance of Eucalyptus miniata—they are loaded with 
trusses of orange-colored blossoms ; or when, asin the 
instance of Eucalyptus pheenicea, a tree of this genus 
produces crimson flowers vieing with the Ratas of 
New Zealand, but shows an infinitely easier growth. 
We should promote the cognizance of the timber, 
not merely from museum specimens, but also as much 
as possible from the living trees. In a young country, 
particularly, our energies should be concentrated on 
instilling information in this way. Buta tree planted 
during the early days of settlement, if thoughtlessly 
sacrificed in a moment, or allowed to perish from in- 
acquaintance with its nature or value, cannot be re- 
stored to its attained size, even if replanted, before 
the end of this century. 
As yet we know but little of most Oaks, as far as 
technology is concerned. We should watch their 
growth in various geologic formations; weshould note 
their adaptability to certain climatic regions. About 
half a hundred kinds have been brought together here 
by myself, but there are 300 kinds in different parts 
of the globe to select from. Quercus Lusitanica has 
shown itself here one of the most eligible for avenues, 
on account of its rapid growth, its protracted verdure, 
and complete umbrageousness.* Our Eucalypts are 
as eagerly tested and watched elsewhere, as we ought 
to ascertain the effect of our clime on introduced tim- 
ber trees. Our Blue Gum-tree will still grow from 
Toulon to Nice; at Cannes the tender branches are 
*A variety of this species yields the nut-galls of commerce.
