fire, a new and vigorous vegetation will be ob- 

 served shooting above the soil. Ecobuage 

 can also be accomplished, by removing the 

 uppermost layer of soil containing the organic 

 matters, and forming therewith a kind of fur- 

 nace to which set fire. As the flame makes 

 its way through this mass of earth, roots, 

 turfs, &c., add green turf to close the issues 

 which are formed. Thus may be obtained a 

 slow combustion, which enables a thorough 

 absorption, by the carbonated earthy envelope, 

 of all the gases disengaged during the opera- 

 tion. 



The object of this process (Ecobuage,) is to 

 set at liberty, by a slow decomposition, the 

 principles contained in the vegetable matters, 

 and thus render them available to the soil- 

 In this way we can hasten the circulation of 

 the elements of the plants and present them 

 in a state for immediate assimilation ; whilst 

 the same plants, when left to spontaneous pu- 

 trefaction, decompose but slowly and partially, 

 and produce results inappreciable to any one 

 crop.
