cheap furniture, woodenware, cooperage and paper pulp. Maple 

 sugar is occasionally made from this species. 



Robinia pseudacacia, Linnaeus. 

 (locust, black locust, yellow locust.) 



A slender tree, with erect brittle branches forming an oblong 

 head, and deeply furrowed dark brown bark. It reaches a height 

 of 80 and a diameter of 4 feet. 



It occurs from Pennsylvania to Georgia along the Appalachian 

 mountains, growing with hickory, black walnut, ash, white oak, 

 and the chestnut ; and reaches its best development on the western 

 slopes of the mountains in West Yirginia. It has been natural- 

 ized in most of the states east of the Rocky mountains.

In this State it occurs on the lower ridges of the mountains, 

 and probably for some distance east of the Blue Ridge. (Fig. 7.) 



Forest trees bear seed only once in three or four years. In the 

 open the production of seed is more frequent and seedlings, which 

 are short-lived in the shade, more common. The locust is readily 

 propagated by root suckers, and trees as large as one foot in 

 diameter sprout from the stump. The growth is rapid in youth; 

 in mature trees much slower. When cut in the forest, it is usually 

 succeeded by oaks and chestnut. Old trees are apt to be hollow 

 at the butt, and frequently in the upper part of the stem, from 

 the entrance of water where the brittle limbs have been broken off.
