Dr. John A. Warder says : " In this prairie country one of the very best trees for street planting is the green ash. The size is just right, the growth when young is rapid, the form is easily controlled by judicious trimming, and the foliage is very neat and of a healthy green, which is nearly the same on both sides of the leaves. Then, too, the trees may be had at reasonable rates from any nurseryman. Whole blocks, or indeed whole streets, might well be planted continuously with the green ash, and produce a good effect.
