How Trees differ from each other. 129 



141. Roots are divided also into different 

 kinds, according to their length of life ; into 

 annual, or those which live but one year ; bi- 

 en'ni-al, those which live but two years ; and 

 per-en 'ni-al, those which live several years, 



142. To which of these divisions does a 

 morning-glory belong ? A rose bush ? A 

 pear tree ? A currant bush ? A fern ? 

 Beets ? A cotton plant ? Grasses ? Indian 

 corn ? Carjots ? Butter-cups ? 



Some trees, like the oak, cedar, pine and 

 olive, live for centuries. 



143. Trees differ also in their 

 stems or trunks; some grow up 

 for a short distance from the 



ground and then Hyacinth, 

 branch out in every direction, 

 like the apple tree ; while 

 others grow up almost in a 

 straight line, ten times as high 

 as any apple tree ; such are the 

 mammoth trees of California, 

 the eucalyptus* trees of Aus- 

 tralia, and the cocoanut trees 

 of Africa and Asia. 



The trees just named are remark- 

 able for the great distance between 

 the ground and their lower branches. 

 The cocoanut and other palms have 

 all their leaves at the top.
