THE EUCALYPTUS GLOBULUS.

Many trees were planted in the most unhealthy spots ; and their 
value was so soon recognized by the peasants, that they would 
steal the leaves for the purpose of making decoctions, and called 
the Eucalyptus Varbre a la fievre. Now single trees and plan- 
tations are found near Seville, between Seville and G-ranada, at 
Granada and Malaga, also near Lisbon. Nice, Monaco, Hy&res, 
Cannes can now boast of their Eucalyptus plantations, especially 
in private gardens, where they are highly ornamental ; and the 
Eoman Campagna, that hotbed of fever, might without doubt be 
considerably modified if planting were undertaken on an ex- 
tensive scale. Hitherto in Italy little lias been done, though 
Garibaldi and other leading men have greatly interested them- 
selves in the subject. The Trappist monks in the Campagna, 
however, have sanified their immediate district by extensive 
Eucalyptus plantations, which they proudly show to visitors, 
stating that formerly they were constantly being stricken down 
by malaria, whilst now it is almost unknown. Again, a little 
railway station in the Var, near Cannes, was at one time so 
terribly unhealthy, in consequence of miasma, that the station- 
master had to be changed every two years. Eucalyptus trees 
have been planted in considerable quantities round the station, 
and now it is no longer necessary to make these frequent changes. 
It is proposed to try Eucalyptus plantations in Cyprus, and we 
trust the scheme may be carried out. 
Among ourselves efforts to naturalize the Eucalyptus out of 
doors have almost always failed ; and the curious must visit the 
glass houses at Kew to familiarize themselves with this famous 
tree. The cold English winters and springs kill the saplings 
even in sheltered situations, so that we may hardly hope to see 
Eomney Marsh or other aguish tracts metamorphosed after the 
manner of Algerian plains. The Eucalyptus requires as mild 
a climate as the orange, its zone having now been pretty accu- 
rately defined by botanists. 
It is hardly necessary to remind the reader of the sanitary 
effect of trees or the unwholesomeness of treeless wastes. All 
who have travelled will recall many instances in point — Madrid, 
for example, which, in consequence of its arid environment, 
possesses one of the unhealthiest climates in Europe. Again, 
in Corsica the same physical conditions have been brought 
about by human interposition, the once fertile plains of Niolo 
now being completely denuded of trees, to the great detriment 
of its inhabitants ; whereas in the sixteenth century the whole 
country was covered with woods and forests. 
In Italy the destruction of forests in many places has been 
followed by the scirocco. Professor Ansted cites in one of his 
works the example of a pine forest near Eavenna. The forest 
was cut down, and the hot wind immediately appeared ; it was
