188 MODERN FOREST ECONOMY. 



of this may be as distinct, though not more so perhaps, 

 as the economy of a nation may be distinct from the 

 economy of the household. It may be considered that in 

 the one case, and in tfoe other alike, what relates to the 

 whole relates to all its constituent parts ; and it may be 

 alleged that sylviculture comprises arboriculture. I am 

 not disposed to question or deny the allegation ; I content 

 myself with remarking that arboriculture does not as a 

 consequence comprise sylviculture, and it is sylviculture, or 

 the culture ol woods, comprising as this does the culture 

 of the trees of the aggregate of which the woods consist, 

 which is here brought under consideration. 



The sylviculture of the Continent is practised with 

 different objects immediate!}*- in view ; and with variations 

 in these it presents different phases. It is practiced most 

 extensively in connection with the management of exist- 

 ing forests. Information in regard to what is done in this 

 way may be obtained by English students from a treatise 

 entitled Elements of Sylviculture, by the late G. Bagneris, 

 Inspector of Forests, and Professor at the Forest School of 

 Nancy, which has been translated from the French by 

 Messrs Fernandez and Smythies, of the Indian Forest 

 Service. 



But besides being carried on with a view to maintain- 

 ing and increasing the produce of existing forests, sylvi- 

 cultural operations have also been carried on, and that 

 upon an extensive scale, and with success, to counteract 

 evils which have followed the destruction of forests. 

 Sylviculture has been employed thus successfully to pre- 

 vent desolations occasioned by torrents and inundations. 

 Details are given in a volume which I have published 

 entitled fteboisement in France ; or Records of the Re-plant- 

 ing of the Alps, the Cevennes, and the Pyrenees, with Trees, 

 Herbage, and Bush, with a view to arresting and preventing 

 the destructive consequences of torrents. 



It has been employed to arrest and utilise sand-drifts.
