 apparent, that even in 1792 the governor of the 

 Department of Basses- Alpes reported : " The clear-

Yet, in spite of these early warnings, which were 

 supported by theoretical discussions of such sound 

 reasoners as Boussingault, Becquerel, and others,

 had been destroyed by fire and excessive grazing, 

 in consequence of which the mountain streams, 

 turned into torrents, had laid waste about 8,000,000
