several varieties being grown, and planted in suitable ground, 
they may be cut down in 10 to 12 years. 
As propagation is made by seeds, the varieties grown 
here are remarkably exempt from the ravages of the insects 
inimical to the growth of the Eucalyptus. 
The trunk of the Eucalyptus varies much in its manner 
of growth, sometimes it is straight as the mast of a 
vessel and at others contorted and twisted. In nearly all 
varieties the trunk tapers gradually from below upwards, 
rendering it suitable for use ‘as masts, high posts, etc. 
The bark, too, varies greatly, even in the same tree, 
changing its aspect with its age. 
The colour of the trunk of the Eucalyptus varies from 
white to dark brown or gray, and its grain from fine, 
straight and regular to the most interwoven texture. Gener- 
ally it is not easily cut. 
The timber is put to innumerable uses for all kinds of 
civil and naval construction as well as for many industrial 
purposes, and it is rare that the quality of wood is inferior. 
All varieties of Eucalyptus have perennial foliage which 
is of advantage to the horticultural value of the plant. The 
foliage and shape of the tree vary greatly, now dense and 
affording cool shade, now sparse and suitable for situations 
where plenty of sunlight is necessary. 
The uses of the Eucalyptus are much more numerous 
and of varying kind than those of any other kind of tree. 
Rapid in growth it serves for the planting of groves 
and woods and for ornamentation of park, estate or garden. 
The surrounding air is purified, it supplies bees with 
nectar, it beautifies the landscape, its wood is abundantly 
serviceable, as fuel its heating power is superior to coke, 
it has valuable medicinal properties, its hark may be used 
for tanning, etc., etc. 
The oil dictitied from the leaves and young shoots of 
the Eucalyptus is used in the manufacture of soap, and for 
medicines, yielding a return to the producer of 1.6 to 
1.8 per cent.
