18 FOBEST CULTUBE AND 



future naturalization of tlie Eucalyptus Mueller is the 

 savant who justly calculated the future of the tree, 

 traced it in its itineracy, and predicted its destiny. 

 Ramel is the enthusiastic amateur who has thrown 

 body and mind into the mission of propagating it. 

 Both have faith ; but one is a prophet, the other an 

 apostle, and, in the noble confraternity of services, 

 public gratitude will not separate the names that are 

 bound together by friendship." "The Eucalyptus 

 globulus, known as the Blue Gum, was introduced 

 into Algeria in 1854, while its name and properties 

 were unknown. It is now being planted by hundreds 

 of thousands, in groves, in avenues, in groups, in iso- 

 lated stalks, in every section of three provinces." A 

 colonist and ardent planter, M. Trottier, regarded this 

 tree as possessing a forest substance capable one day 

 of enriching the colony, and he took for the motto of 

 one of his writings the following : " The wood of the 

 Eucalyptus will be the great product of Algeria." 

 Carrying his confidence still further, he saw the des- 

 ert retreating before this colonized tree, and, specu- 

 lating upon the incontestible fact that the forest created 

 humidity and changed the hygrometrical regime of 

 a country, and remembering, besides, the subterrane- 

 ous sheets of water beneath the arid surface of this 

 region, he boldly named another pamphlet "2%e 

 Wooded Desert and Colonies," thus conceiving the idea 

 that the great Sahaea Desebt could be reclaimed 

 by planting this tree. He estimated the profits from 

 planting the Eucalyptus in the colonies of Algeria to 

 be from one thousand stalks, in five years, to yield 

 a gross revenue of $240, and $10,650 in twenty-six 

 years. He based the estimate on the annual growth.
