BULLETIN NO. 62. 



trees sprout badly and are rather short lived. It is easily propa- 

 gated from seed, suckers or cuttings, though the first is by far 

 the best method of propagation. It likes best a deep, rich, 

 sandy soil, where its growth is wonderfully vigorous; in such a 

 soil, an immense number can be planted on a small area of 

 ground. 



The wood is greenish brown on the outside, but the sap 

 wood is yellow. The timber !js strong, heavy, very durable, 

 and reaches a large size; weight per cubie foot, 46 pounds.

 its flowers, while borne the

 than the other species. Its 

 branches spread out and form 

 a fine, broad, dome-like head;

 the Black Locust, it has none 

 of the dead, scragly and un- 

 sightly limbs, always to be 

 found on that tree. It suck- 

 ers but little, and is seldom 

 a nuisance in that respect. 

 The branches of this tree are 

 thickly armed with strong,

Honey Locust is not so rapid a grower as the Black Locust, but 

 eventually becomes a larger tree and lives longer; its wood is
