42 EUCALYPTS CULTIVATED IN THE UNITED STATES. 
he receives many inquiries concerning the merits of certain species for 
bee pasture. Ina subsequent portion of this publication will be found 
a list of the species useful for this purpose. In planting trees for 
forest cover, wind-breaks, shade, timber, or fuel it would be well. 
wherever the bee industry is important, to select varieties recognized 
as flower producers. Several species valuable for the purposes men- 
tioned above—notably the Sugar Gum (4ucalyptus corynocalyz), the 
Red Gum (£. rostrata), the Red Iron bark (£. stderorylon), E. hemz- 
phloia, and £. polyanthema—are profuse bloomers and are thronged 
with bees during the blooming season, which with some species is 
quite protracted. 
AS IMPROVERS OF CLIMATE. 
The Eucalypts have the reputation of benefiting the climate of those 
regions where they have been planted. Evidence upon this subject 
is so conflicting, however, that the truth is ascertained with difficulty. 
Whatever the fact may be, the belief is quite general, especially in 
southern Europe, that the effect of Eucalypts upon the climate is 
distinctly sanatory. 
The plantation of Eucalypts at Tres Fontane, in the Roman Cam- 
pagna, is the instance most generally cited by those who contend for 
the beneficial influence of these trees on theclimate. In fact, the general 
planting of Eucalypts throughout southern Europe seems to have been 
given a decided impetus by reports of the resultsat Tres Fontane. On 
this point Charles Belmont Davis, American consul at Florence in 
1894, writes in Consular Reports No. 168 as follows: 
It is this latter quality [the property of distributing a balsamic atmosphere] which 
has brought the Eucalyptus into such prominence in Italy, and has been the cause 
not only of the planting of thousands of trees by private individuals and public cor- 
porations, but of its receiving the indorsement of the Italian Government as well. 
He adds: 
Whether the plant does absolutely contain such a healthful quality as many 
attribute to it has always been and still is a question in the minds of many who 
have given the subject intelligent thought and systematic experiment. That the 
planting of these trees has met in some districts with a degree of success in allaying 
the ravages of malaria there would seem to be little doubt. 
In the consular report mentioned aboye Wilbur B. Hall, American 
consul at Nice, writes: 
The Eucalyptus seems destined to revolutionize silviculture in the countries men- 
tioned [France, Algeria, Italy, Spain, Corsica, Portugal, and Cape Colony], not only on 
account of the many remarkable properties of the tree, its resin, its wood, and its 
rapid growth, but also its great power of absorbing enormous quantities of water 
from wet and swampy lands, drying them and rendering them fit for cultivation, as 
well as its tendency to thus eliminate malarial conditions from the lands whence it 
oTOWS.
