This fact has been demonstrated by Mr. Liversige,
professor in the University of Sydney, Australia. Among us also, although
everybody was convinced by the statements of the press that the locality
of the Tre Fontaine, near Rome, had been freed from malaria by means of
the eucalyptus, people were disagreeably surprised by an outbreak of very
grave fever occurring throughout the whole of this colony in 1882, a year
in which all the rest of the Roman Campagna enjoyed an exceptional
salubrity. If, alongside of these hygienic uncertainties, we place the
agricultural uncertainties, we must conclude that it is necessary to
contend strongly against this fanatical prejudice in favor of the
eucalyptus tree. These plants are, in fact, very capricious in their
growth. In full vegetation during the winter in our climate, they are
often killed instantly by a sharp winter frost, by damp cold, by the
frosts of spring, or by other causes which the botanists have not yet been
able to determine. At other times, if the winters are very mild, these
plants grow too rapidly in height, and then are broken short off by
moderately strong winds. It should further be mentioned that these
plantations are sometimes very expensive.
