works seem to have accompanied the planting of Eucalyp- 

 tus in the cases where the best authenticated sanitary im- 

 provement occurred. M. Lambert, an Algerian forest offi- 

 cer, states that in the Forest of St. Ferdinand he had a 

 station so unhealthy that it was uninhabitable. After the 

 growth of a plantation of Eucalyptus set out at that point 

 the fevers disappeared and an agent, already suffering from 

 malaria moved to this station, entirely recovered. 



Besides these M. Carlotti cites the great improvement 

 at the Maison-Carree in Algiers and in the Commune of 

 Columb in the Republic of Columbia in South America v 

 due to extensive Eucalyptus planting. 



M. Gimbert, in a communication to the Academy of 

 Sciences, takes strong ground in favor of the sanitary value 

 of Eucalyptus plantations. Amongst the places cited by 

 him to establish his point are the environs of Constantine 

 Algiers, the Cape of Good Hope Colony, and in the French 

 Departement du Var. 



In No. 1 68 of our Consular Reports, obtained at my 

 request, there are a number of valuable reports on this 

 question. 



All of these many experiments of Eucalyptus planting 

 for health improvement, are favorably spoken of except 

 in the report of Prof. Tommasi-Crudeli. This distin- 

 guished scientific man does not think that Eucalyptus 

 planting will entirely prevent malaria. He examined the 

 locations in Italy where benefits from this source were 

 claimed, and shows that malaria has recurred in some of 

 them, and that drainage works had been carried out in these 

 places as well as Eucalyptus tree planting. A contro- 

 versy has sprung up on this question, especially as to the 



ects of Eucalyptus planting at Tre Fontane in the
