earth and make the soil fertile. In this way trees prevent 

 droughts. 



Trees, too, make homes for birds. Birds destroy the insects 

 that injure the crops, so trees really increase our crops by sheltering 

 birds. 



Trees, by their strong roots, hold together soil and mold, and 

 thus they are useful in preventing landslides. 



But, useful though they are, trees are often thoughtlessly cut 

 down. Forest fires destroy many valuable trees. 



Our government has taken measures to preserve trees. Every 

 encouragement is given to plant them. The children in our public 

 schools have a day set apart for planting trees. We place them 

 around our schools and in our parks. 



Strict regulations are also made to control forest fires and 

 prevent their spreading. Laws are passed to prevent the cutting of 

 trees on public lands. By such means we hope to preserve our 

 young trees. 



Boys and girls should do all they can to help our government 



in saving our trees.
