" The English first experimented with sanitary plantations in 

 the Cape Colony. In two or three years they have changed the 

 climatic conditions and the aspect of the unhealthy regions of 

 this possession. Some years afterwards the Algerians planted 

 Eucalyptus in our part of Africa. The following are some of the 

 results obtained : — 



" At Pondouk, 32 kilometres from Algiers, says M. Trottier, I 

 possessed a property, the house of which was situated near the 

 river Hamyze, which by its emanations gave ague every year to 

 the farmers and their servants. In the spring of the year 1867 I 

 planted on this farm 13,000 Eucalyptus Globulus. In July, 1867, 

 the season at which the fevers begin to rage, the farmers enjoyed 

 a complete immunity. The trees, however, were scarcely 2 or 

 3 metres in height. From that time the resident population has 

 been exempt from fevers." 



'*The farm of Ben-Machydlin in the neighbourhood of Con- 

 stantino was, some years since, noted for its insalubrity. It was 

 covered with marshes in winter and summer. To-day all this has 

 disappeared. 14,000 plants of Eucalyptus have in five years 

 completely dried the soil. They constantly exhale into the 

 atmosphere aromatic vapours ; the farmers no longer have fever ; 

 their children are the picture of health and vigour. The factory 

 at Gue de Constantine was surrounded by a marsh, the pestilential 

 emanations of which rendered the use of the establishment 

 impossible during summer. The idea occurred to M. Saulieve of 

 sowing in these marshes a great quantity of Eucalyptus. In 

 three years five hectares of boggy land were converted into a 

 magnificent park. The water had been literally drunk up by the 

 trees, and the workmen no longer had fever. 



"The same hygienic revolution occurred in consequence of 

 extensive plantations of Eucalyptus Globulus on the farm of 

 La Maison-Carree, situated in the same neighbourhood, and in 

 which the inhabitants frequently succumbed to ague. These 

 great and rapid successes are recorded in a Report drawn up by 

 an Agricultural Jury, and are consequently by no means the result 

 of individual prepossession. Residents in Cuba, upon whose 

 statements we can rely, have assured us that in the unhealthy 

 districts of the island in which they have been planting Eucalyptus 

 tor some years, malarious diseases have disappeared. 



"According to Ramel, Australia is salubrious where Eucalyptus 

 prospers, pestilential in places where the tree does not exist.
