Species of pines. In 

 the United States there 

 are about thirty-six 

 species of pines grow- 

 ing wild. The white 

 pine formerly grew 

 abundantly in parts of 

 the Northern states 

 from Maine to Minne- 

 sota and in southern 

 Canada. It furnished 



a vast amount of good lumber, but the supply is now 

 nearly exhausted, so that white pine of good grade 

 brings a high price. Southern yellow pine has taken 

 its place for many uses. It is a 'harder and heavier 

 wood than white pine, and contains more resin, but it 

 is likely to split along the annual rings when it is nailed. 

 Test the cleavability of a piece of yellow pine by 

 driving a nail through it near the end. 



In California, the sugar pine grows 200 feet tall and 

 produces cones that may be 18 inches or more in length.
