As the latter tree will grow well in 1 

 places where the Green Ash is planted it 

 is to be recommended instead of the in-

 along the streams and in the 

 low lands. West of this 

 line it is planted abundantly, 

 and it thrives in nearly all 

 parts of the State where 

 sufficient water is available.

This is another of the quickly grown 

 native trees against which there is a good

 that it is not as valuable a tree as some in
