CHAPTER II 



THE FOREST FAMILIES 



Trees are as queer in picking out places to 

 live and in their habits of growth as are the 

 peoples of the various races which inhabit the 

 world. Some trees do best in the icy northland. 

 They become weak and die when brought to warm 

 climates. Others that are accustomed to tropical 

 weather fail to make further growth when ex- 

 posed to extreme cold. The appearance of Jack 

 Frost means death to most of the trees that come 

 from near the equator. Even on the opposite 

 slopes of the same mountain the types of trees are 

 often very different. Trees that do well on the 

 north side require plenty of moisture and cool 

 weather. Those that prosper on south exposures 

 are equipped to resist late and early frosts as well 

 as very hot sunshine. The moisture needs of 

 different trees are as remarkable as their likes 

 and dislikes for warmth and cold. Some trees 

 attain large size in a swampy country. Trees of 

 the same kind will become stunted in sections 



where dry weather persists.
