that in the second year the homesteads would with care be 
habitable, and in five years there would be a rich crop of 
wood off the plantation, whilst the ground cultivated for 
other purposes would be richer of course, because it would 
be receiving that attention which for a long time it never 
has had. The trial in this point of view ceases to be a specu= 
lation; it is a fine opening for producing wealth and comfort. 
Even if the malaria were not removed the gain from the 
wood would be great. 
It is said that the tree will not grow if the temperature 
falls below 4° C, or about 25° — 26° Fahr. One specimen had 
lost the top leaves by frost ; but the great fact remains that 
they lasted the five years required. There are many varieties 
of the tree, and some grow in Australia at the height of 
4,000 feet, but I cannot learn if these produce as much wood 
or oil as the globulus ; if they do, they promise to be valuable 
in this country. The eucalyptus viminalis was said to be 
the best for drying up swamps, and it had the appearance of 
a willow ; but it was by no means so full of oil to all appear- 
ance or so fragrant as the eucalyptus globulus. The 
eucalyptus coccifera never suffered at all from the frost at 
Tre Fontane, but it had not been long tried ; still the attempt 
was made in its tenderest years. 
M. Bosisto says that the Eucalyptus Amygdalina grows 
350 feet on high undulating forest land, but not above 100 
miles from the coast. This may be the best species for 
Italy. M. Carlotti seems to recommend the Globulus ; 
M. Bosisto’s remarks seem to favour the amygdalina. 
The conclusion arrived at was that the frost of the Cam- 
pagna would not hurt to any great extent any species of 
the tree tried there, and the principal specimen especially. 
Nearer the Sabine hills it was said not to grow so well, but 
there is abundant low land where it is required. 
The value claimed for the eucalyptus is intelligible if we 
consider it as continually giving out a medical agent. So
