Celestial tree in New York and Philadelphia

In New York and Philadelphia, the Ailantus is more generally known by the name of the Celestial tree, and is much planted in the streets and public squares. For such situations it is admirably adapted, as it will insinuate its strong roots into the most meagre and barren soil, where few other trees will grow, and soon produce an abundance of foliage and fine shade. It appears also to be perfectly free from insects; and the leaves, instead of dropping slowly, and for a long time, fall off almost immediately when frost commences.
