and possibly cinchona, and coffee also ; so, lucrative 
fibres, dye-plants of easy growth and simple prepara- 
tion, as instanced by grass-cloth, or madder ; or medi- 
cinal plants, such as senna, and various herbs, or, per- 
haps, even the Erythroxylon coca, a plant of almost 
fabulous properties. Or should the settler prefer, be- 
yond raising the simple requirements for his rural 
life, to devote his attention solely to the gain which 
the surrounding timber treasuries are certain to offer, 
he will find ample scope for his energy and industry. 
The Eucalypts, as now proved by extensive and accu- 
rate experiments, will yield him tar in. abundance ; 
they will furnish fibres, even those of Stringy-bark as 
one of the cheapest and most extensively available 
paper material. By a few simple appliances he may 
secure, simultaneously with the tar, also wood-vine- 
gar and wood-spirit; and these again might locally be 
at once converted into dye materials and varnishes. 
He might obtain potash from woods, and volatile oils 
from the leaves of Eucalypts in almost any quantity, 
by artless processes and with scarcely any cost. He 
might gather the gum-resins and barks for either 
medicinal or tanning purposes, or he might effect a 
trade in Fern-trees ; he might shake the Eucalyptus 
grains out of their capsules, and might secure locally 
other mercantile substances far too numerous to be 
enumerated here. Whoever may choose these ranges 
asa permanent home, and may direct thoughtfully his 
attention to the future, will recognize that the mere 
scattering of the acorns of the Cork-tree or the seeds of 
the Red Cedar over cleared and yet sheltered ground, 
or the planting of the vine and olive, will yield to his 
descendants sources of great riches.
