The Eucalypts are now grown in America, especially in the South- 
western United States, more extensively than any other exotic forest 
tree. During the past forty years they have been planted here and in 
other parts of the world for ornament, for sanitary improvement, for 
shade, for wind-breaks, for fuel, for oil, and for timber; and incident-. 
ally they have been useful in many other ways. In fact, they have 
probably served more esthetic and utilitarian purposes than any other 
forest trees that have been planted on this continent. 
These trees have been studied and extolled alike by botanists, gar- 
deners, and foresters. They are worthy of all the attention that has 
been given them and deserve to be still better known.” The late Baron 
Ferdinand von Mueller, Government botanist of Victoria, Australia, 
the most renowned student of the great Australian genus Eucalyptus, 
prophesied jn his scholarly Eucalyptographia that ‘*‘The Eucalypts 
are destined to play a prominent part for all times to come in the 
silvan culture of vast tracts of the globe; and for hard-wood supplies, 
for sanitary measures, and for beneficent climatic changes all countries 
within the warmer zones will with appreciative extensiveness have to 
rely on our Eucalypts during an as yet uncountable period.” All who 
have lived where Eucalypts grow can realize fully the force of the 
prophecy and the great value of the genus to mankind, both present 
and prospective. 
In the following pages it EKucalypts are viewed mainly from the 
standpoint of their usefulness, only incidentally being treated as orna- 
mentals. No attempt is fade) to present an exhaustive botanical trea- 
tise of the Eucalypts. The botanical features introduced are intended 
to be subservient to the interests and purposes of the forester. 
Only the large arboreal species are discussed—that is, species attain- 
ing a height of over 40 to 50 feet and a diameter of over 1 foot. Many 
of the species consisting of smaller trees are very interesting to the 
botanist and gardener, but they are of comparatively little interest to 
the forester. 
This publication is not a general treatise on the genus Eucalyptus,
