36 ON THE EUCALYPTUS NEAR ROME.. 



Of the general question and the inquiries of Dr. Balestra 

 and others I hope to speak after some time. At present I 

 shall content myself with a few recommendations. 



The conclusion to which I come is^ that enough is known 

 to prove that great henefit may be expected from the cul- 

 tivation of the Eucalyptus globulus and^ perhaps more es- 

 pecially^ the E. aniygdalina, with others. 



The best plan would probably be to begin by surrounding 

 with trees any house to be inhabited in a district subject 

 to malaria. 



The benefit seems to arise in the second year^ as soon as 

 the plants give out a great deal of odour. 



The experiment near Rome is very small and somewhat 

 mixed, but is nevertheless enough to give great hope to those 

 who have an opportunity to try the same in the Campagna 

 and elsewhere. 



The experiments made in other countries seem to indicate 

 a certainty of benefit. 



The value of wood being great near Rome, theEucalyptus 

 promises a substance much wanted ; and there is therefore 



a double reason for growing it.

The growth is unusually rapid — so much so that even 

 in five years the wood is much larger than that usually 

 employed for burning in Rome. The expense of the crop 

 is therefore small ; and Rome is thus promised both a sup- 

 ply of health, of warmth, and of power by the outlay of little 

 money with little labour. Apparently Rome need never 

 envy us our coals ; for her coals thus got will last for ever. 



I have made no new discovery in relation to this subject, 

 but have only put together a few of the more striking points, 

 that my Roman friends may be induced to stimulate action 

 in those who are more directly concerned, and not leave 

 neglected such a promising source of comfort and of national 

 wealth ; for not only is this great source of power to be
