Preface ix 



subsequent decrease in the woodland area throughout Britain, 

 we have lagged far behind continental countries with regard 

 to the improvement of our knowledge of Forestry. With the 

 present shrinkage in the agricultural and pastural value of land, 

 however, there certainly is now scope for applying a knowledge 

 of economic and purely financial Forestry, i. e. Sylviculture, to 

 considerable tracts that are now lying waste and unproductive.
