 extended much further than most farmers are aware of. 

 To attempt making such soils produce, without che-

Soils not calcareous, containing much inert vegetable 

 matter or peat, have a tendency to produce wild sorel, a 

 plant considered in general as an indication of the want 

 of fertility in the soil. This is certainly corredt, if the fer- 

 tility of the soil is only to be estimated by the use or 

 value at market of the crop, but not as it respedls vege- 

 tation itself ; for a soil of the above description often pro- 

 -rduces a most plentiful crop of sorel. In this case, as it 

 applies to the further improvement of the land, the growth 

 of sorel should as much as possible be encouraged, 

 even by sowing the seed for this especial purpose. The 

 vegetation of this plant is no doubt promoted in
