The uses of trees are manifold, and a country from 

 which the forests have been destroyed becomes almost 

 uninhabitable and worthless to mankind. The forests 

 furnish wood and timber, exercise beneficial influences 

 on the climate, act as regulators of the waterflow, pre-

 Besides furnishing wood and timber, many trees yield 

 other products of great economic importance, especially 

 the numerous kinds bearing fruits. The esthetic value
