 lous; teeth of the calijx unarmed; legumes smooth. The Locust Tree grows 

 native in Pennsylvania and the more southern and western States, and is 

 abundantly naturalized in New England. In the durability, hardness and 

 lightness of its timber, and the beauty of its foliage and flowers, it is exceeded 

 by few trees of the American forest. West of the Alleganies it sometimes 

 attains the hight of 80 feet, with a diameter of 3 or 4. In N. England it sel- 

 dom exceeds half the above dimensions. The pinnate leaves have a beautiful 

 symmetry of form, each composed of 8 — 12 pairs of leaflets, with one at the 

 end. These are oval, thin, nearly sessile, and very smooth. Flowers in nu- 

 merous, pendulous clusters, diffusing an agreeable fragrance. These are suc- 

 ceeded by a narrow, flat pod, with 5 or small brown seeds. When young,
