ties, as well as the development of forest communal life and the 

 production of materials for the maintenance of industry. 



Transportation has been an important problem in our forest areas. 

 Forests naturally lie in rather remote and inaccessible regions or even 

 in the wilderness. The desire to make these areas accessible for rec- 

 reation, hunting, and fishing, the restoration of health, and the enjoy- 

 ment of the scenery under the most attractive and healthful condi- 

 tions, has induced the construction and improvement of transporta-

tion by highway, rail, or water. These same facilities also make pos- 

 sible the easier removal of the products of the forest. The materials 

 may be timber, minerals, sheep for wool or mutton, cattle for beef 

 and other meat products, furs and other by-products of game animals, 

 resin for the manufacture of naval stores, as well as many other com- 

 modities. The principle of sustained yield management * of our for- 

 ests has therefore been greatly broadened beyond the primary objec- 

 tive of timber production of materials for shelter and construction. 



Forestry has to do with trees individually and collectively. More 

 than one thousand species of trees are recognized in the United States.
