assured. Thus forestry aims to do for timber land just what 

 scientific agriculture aims to do for farm land. 



By reckless and wasteful lumbering the United States 

 has lost very much of one of its most valuable resources. 

 Governmental action was necessary to prevent the coming 

 of a lumber famine, and, even as it is, the price of timber is 

 many times what it would have been if the forest resources 

 of the United States had been scientifically managed. 



Foresters are concerned not only with the management of 

 forests now existing; they are also concerned with the 

 reforestation of lands from which the timber has been cut 

 or burned. Forest fires have caused losses of milHons of 

 dollars annually, and the forest service of the government 

 fights and seeks to prevent these fires. It has also replanted 

 with new trees many thousands of acres which have been 

 cleared by fire or ax. 



C. Forestry outside of Forests. — Forestry is not restricted 

 to forests. The term is also applied to the scientific culture 

 of trees which do not grow in forests. Many cities employ 

 foresters whose business is the planting and care of trees in 

 parks and along streets. This is a division of the subject 

 which directly concerns even more people than does forestry 

 proper, for nearly every one is constantly interested in the 

 presence and health of trees on lawns and along sidewalks, 

 while they may visit forests but rarely. 



Ignorance of how to set out trees often causes unnecessary 

 loss. Trees should be set out only in early spring or in the 

 fall; fall planting is preferable. The holes should be con- 

 siderably larger than the root mass. After the roots have 

 been placed naturally, the holes should be gradually filled 

 with pulverized soil, gently tamped. The young trees
