The Black Locust {Rohinia pseudacacia), also called yellow 
locust, is tough, coarse in texture, durable in contact with 
soil, and shrinks a good deal in seasoning ; the yellowish 
sapwood is very narrow, the heartwood is brownish with 
shades of red and green. Used in America for wagon 
hubs, treenails, railway ties, posts, etc., and abroad for 
furniture, it is one of the best woods for insulator pins on 
telegraph posts, but it is getting scarce. 
The Honey Locust (Gleditschia triacanihos) is a somewhat 
similar wood, but so far is not much used, except for 
fencing and fuel. 
Some is known in the trade as brown locust and sofd in 
logs by weight. 
Great numbers of locust trees were planted in England 
many years ago, chiefly owing to the praise given them by 
"William Cobbett. 
Locust also grows in Australia, but must not be con- 
founded with the locust of the tropics {Hymenaa courharil). 
The tree is very subject to damage by a boring insect. 
Weight of wood 42 to 48 lbs. per cubic feet. 
Osage Orange or Bois d'Arc {Madura aurantiaca), a tree 
found in Texas and Louisiana, produces a very hard, heavy 
wood of brown colour which tarns grey on exposure, 
strong, tough and flexible, of coarse texture which shrinks 
a good deal in drying, and is very durable. It is much used 
in the United States for wagon framing and motor wheels, 
and for the latter has been used in Europe ; it is easily 
split, so is unfit for hubs, but it is very suitable for spokes ; 
it is considered to be one of the timbers likely to supply the 
place of black locust for insulator pins on telegraph poles. 
Dogwood {Cornus florid a), or American box, grows both in 
the States and Canada, and attains a height of about
