THE GREEN ASH.
F. Pennsylvanica, Variety lanceolata, Sarg.
The green ash has narrower, shorter leaves than the parent species and usually more sharply saw-toothed margins. Instead of having pale linings, the leaflets are bright green on both surfaces. This is the ash tree of the almost treeless prairies from Dakota southward, where it not only lives, but flourishes as well as in its native habitat, the rich soil of stream banks farther east. Its range crosses the Rocky
Mountains and reaches the slopes of the Wasatch Moun tains in Utah. East of the Alleghanies the tree is little known. It is in the West that it is the dominant ash. It is one of the few important agencies which have turned the "Great American Desert" into a land of shady roads and comfortable, protected homesteads.
