33 DR. R. ANGUS SMITH ON 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 speculation ; 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° Fahr. One specimen 

 had lost the top leaves by frost ; but the great fact remaias 

 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 E. globulus ; if they do, they pro- 

 mise to be valuable in this country. The Eucalyptus vi- 

 minalis was said to be the best for drying up swamps ; and 

 it had the appeaiance of a willow ; but it was by no means 

 so full of oil, to all appearance, or so fragrant as the Euca- 

 lyptus 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 E. globulus ; 

 M. Bosisto^s remarks seems to favour the E. 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
