THE EXHAUSTION OF SOILS. 



Sir, — In your October issue, p. 4d2, ' K N".,' in his criticism on 

 Mr. Paterson's views on pruning, says,—' If, on the other hand, the 

 covert of unmixed Oak be very open, the soil is liable to be exhausted 

 by heavy annual crops of grass, brackens, and other weeds.' Now 

 if grasses, &c., which may grow and decay on the same soil year after 

 year for many years, exhaust the soil, how great must be the 

 exhaustion where, along with the production of this grass, the soil 

 produces, say, 100 tons of saleable timber per acre. As ' >L N.' is 

 not singular in the opinion he thus expresses, perhaps he or some of 

 those who hold the same views, will be so kind as to tell us how they 

 became aware of this exhaustion.
