IMPROVEMENT FELLINaS. 491 



this varied work, while clearing the forest of all unsound, un- 

 healthy, deteriorating or harmful stuff, the main thing to aim at is 

 to get the ground covered with sound, valuable and growing 

 material as quickly as the circumstances in each case will allow. 

 Moreover, in mixed forest, a proper distribution of the component 

 species should not be lost sight of.
