ests of pine. America has forests of yellow pine and white pine, 

 and Canada has forests of red pine. 



Every part of the pine tree is of value. The tall timber is use- 

 ful for shipbuilding. The sap gives tar, resin, and turpentine. 

 The leaves are pressed for their aromatic perfume. The inner 

 bark is used in some countries for food. Pine wool is sometimes 

 made from the leaves. In many countries the seeds are eaten for 

 dessert. 



The sap is obtained by cutting the trees, but if the same trees 

 are cut three years in succession, they will die. It is wrong to 

 destroy these valuable trees. So the turpentine makers move 

 their camps at the end of each year, and give the trees a chance 

 to recover their growth. 



We should protect our trees and never willfully destroy them.
