ORNAMENTAL TREES, ETC. 381 



16. {LocusT. Robina pseud-acacia. 



A tall, beautiful tree, of very rapid growth, with pinnate leaves ; 

 the flowers are produced in racemes; they are white, and have a 

 sweet, fragrant odor. This tree, so valuable for its timber, is liable 

 to the destructive attacks of a worm. In some of the calcareous 

 soils of New Jersey, and where the locust is never annoyed by the 

 borer, no tree is found to be so profitable to raise for timber as this. 

 In that climate, the tree grows very tall and exceedingly rapid. And 

 many hundred trees will grow on an acre, and the timber command* 

 a very high price. A tree of the easiest culture, either from seeds ot 

 division of roots. 



17. {HONEY LOCUST, or THREE-THORNED ACACIA. Gleditschia 



triacanthos. 



A tree of rapid growth, which attains a stately size. The foliage 

 is beautiful ; the leaves are pinnate ; they close at night ; the seed 

 pods are a foot or more in length. The tree is armed with triple or 

 branching thorns, sometimes a foot long, of formidable appearance. 

 A hedge, properly trained, would soon be impassable to man or 

 beast. The stems should be allowed to rise six feet in height, when 

 they must be checked in their advancement to force out lateral 

 shoots. 



18. {{MAGNOLIA, BLUE FLOWERING. M. acuminata. 



This tree is very hardy. It rises erect and in beautiful form to a 

 great height in a congenial climate. The leaves are handsome j the 

 ilowers are of a blue color. 



19. {SCARLET MAPLE. Acer rubrum. 



A large tree, of a very handsome form ; the leaves are cordate,

 April ; they are of a rich crimson hue. The leaves in autumn 

 change to beautiful deep crimson. 



20. {SUGAR MAPLE. Acer saccharinum. 



A beautiful tree, of medium height ; the leaves are large, three 

 or five-lobed ; from its sap sugar is produced , a tree of utility. 



21. *{{WHITE PINE. Pinus strobus, or Weymouth Pine. 



A beautiful evergreen tree, which has been termed the Palm tree 

 of the north. It rises, with a straight trunk, to an enormous height. 

 Mention is made, in Cox's Travels, of a tree at the mouth of the Co- 

 lumbia River forty-six feet in circumference, one hundred and fifty 

 feet to the lowest branches, and three hundred feet high, there 

 called by the traders Roi des Pins. The leaves are very delicate 

 and beautiful ; the timber extremely valuable. 



22. *Pmus LAMB ERTI ANA. 



A splendid genus of the Pine, discovered by Douglas in the north 

 of California. One specimen seen measured two hundred and fifteen 

 feet in height, and fifty-seven in circumference. The cones measure 

 sixteen inches in length. 



Pinus Douglasi, Pinus grandis, and Pinus monteola, are de- 

 scribed as immense and beautiful trees, found growing on the North- 

 west coast of America. 



23. ELASTIC PINE. 



A new and remarkable variety of pine, found growing in the
