LOCUST-TREE. The locust-tree of North America is Robinia pseudacaeia. The wood is greenish yellow, with a slight tinge of red in the pores, it is used like oak. Locust is much esteemed for tree-nails for ships, and for posts, stakes, pales, etc, as it is very tough and durable; it works similarly to ash, and is very good for turning.

" It grows most abundantly in the Southern States; but it is pretty generally diffused throughout the whole country. It sometimes exceeds four feet in diameter and seventy feet in height. The locust is one of the very few trees planted by the Americans."

"According to Mr. Browne, there are no less than 140 species of forest trees indigenous to the United States which exceed thirty feet in height In France there are about thirty, and in Great Britain nearly the same number." - Stevenson's, Civil Engineering of North America, p. 183.

* The locust-tree of the West Indies and Guiana is Hymenea Courbaril, (Semiri,) a tree from 60 to 80 feet in height, and 5 or 6 feet in diameter: the colour of the wood of West Indian locust-tree is light reddish-brown, with darker veins, and the mean size 36 inches. The wood in its native country is used for mill rollers and cogs of wheels. Another tree called Honey Locust, Gleditschia triacanthus, of which the wood splits with great ease, is coarse grained, and but little used.
