Growing Forest Trees in Western Nebraska 



17 



The purpose for which the trees are being planted and the 

 location should determine which of these species should be 

 planted. There is a popular belief that the Cottonwood, Caro- 

 lina Poplar, Norway Poplar, and other similar trees will not 

 live long on the table-land. This opinion is probably correct. Tt 

 is also reported that the Carolina Poplar is more subject to in- 

 jury by borers than the Cottonwood. It is the writer's opinion 

 that neither tree will be injured by borers where the conditions 

 permit of a vigorous growth. It is noticeable that when a tree 

 has become weakened by insufficient moisture or from any other 

 cause, its enemies combine to hasten its death. It may be 

 advisable to plant some of these trees on the table-land on ac- 

 count of their rapid growth, with a view of replacing them later 

 by slower growing .md hardier trees.
