14 -EUCALYPTS CULTIVATED IN THE UNITED STATES. 
species suitable to a great variety of semitropic situations; and there 
are undoubtedly greater future possibilities along this line. Each 
year one or more additional promising species finds its way from Aus- 
tralia to our continent, the usefulness of the genus being thus continu- 
ally extended to newregions. As Americans become better acquainted 
with the Eucalypts in their native home the possibilities for the useful- 
ness of these trees upon our continent will be increased. 
THE EUCALYPTS AS EXOTICS. 
INTRODUCTION OVER THE GLOBE. 
From Australia the Eucalypts have been carried to many parts of 
the earth having a similar climate. The dissemination began on an 
extensive scale about the middle of the past century, largely through 
the labors of Baron von Mueller in Australia and of M. Ramel in 
Australia and in Europe. To be sure, small plantings had been made 
in Europe and in Africa earlier in the century, but we are indebted to 
these men for an adequate appreciation of the reai merits of the genus. 
Prof. J. E. Planchon, one of the students and disseminators of Euca- 
lypts in France, says of these men in his paper upon the Lucalyptus 
globulus,“ that their memory should be associated with the name 
Eucalyptus *‘ wherever this tree thrives as a source of public wealth 
and salubrity;” and then adds: 
In the history of the future naturalization of the Eucalyptus, Mueller is the savant 
who justly calculated the future of the tree, traced it in its [prospective] itineracy, 
and predicted its destiny. Ramel is the enthusiastic amateur who has thrown body 
and mind into the mission of propagating it. Both have faith, but one is a prophet, 
the other an apostle; and, in the noble confraternity of services, public gratitude 
will not separate the names that are bound together by iriendship. 
Others took up the good work in various parts of the world, and, 
during the quarter of a century that followed, the genus became 
widely distributed. It is said that more trees of this genus have 
been planted away from its original habitat than of all other forest 
trees combined. As an indication of how extensively they were being 
planted a quarter of a century ago, the following statement from a 
seed catalogue published in Sidney in 1875 is of interest: 
To give our friends some idea of the demand: We haye sold nearly half a ton of 
seed during the past year. One pound weight should produce many thousand plants. 
The present generation is reaping the benefit of the extensive plant- 
ing of that period. 
The Eucalypts are now grown successfully in southern Europe, in 
northern and in southern Africa, in southern Asia, in parts of South 
America, and in the Southern part of North America. Thus, a por-
