Other native trees. The average height ol" lull grown trees 

 s about 35 or 40 feet. 



Liquidamhar styracijlua is the only North American 

 species. It grows most-rapidly in moist or even wet situa- 

 tions, though it will accommodate itself to a drier soil.

The three trees which properly come under this head

 a foot or eighteen inches in length, are composed of six or 

 eight pairs of opposite leaflets, terminated by an odd one. 

 They contain a very strong aromatic odor, which is emitted 

 plentifully when they are bruised. The large nut, alwavs 

 borne on the extremity of the young shoots, is round, and 

 covered with a thick husk ; which, instead of separating 

 into pieces, and falling off like those of the hickory, rots 

 away and decays gradually. The kernel of the Black 

 walnut, too well known to need any description here, is 

 highly esteemed, and is even considered by some persons 

 to possess a finer flavor than any other walnut. 



The timber of this tree is very valuable : when well sea-
