resembles much in size and appearance the common Shell- 

 bark ; but the nuts are double the size, the shell much thicker 

 and yellowish, while that of the latter is white. It is but 

 little known, except west of the AUeghanies. The Mocker- 

 nut hickory, (C. tomentosa,) is so called from the deceptive 

 appearance of the nuts, which are generally of large size, but 

 contain only a very small kernel. The leaves are composed 

 of but four pair of sessile leaflets, with an odd one at the end. 

 The trunk of the old trees is very rugged, and the wood is 

 one of the best for fuel. 



The Bitternut hickory, (C amara,) sometimes called the 

 White hickory, grows 60 feet high in New- Jersey. The 

 husk which covers the nut of this species, has four winged 

 appendages on its upper half, and never hardens like the 

 other sorts, but becomes soft and decays. The shell is thin, 

 but the kernel is so bitter, that even the squirrels refuse to 

 eat it. The Water Bitternut, (C. aquatica,) is a very inferi- 

 or sort, growing in the swamps and rice fields of the south- 

 ern states. The leaflets are serrated, and resemble in shape 

 the leaves of the peach tree. Both the fruit and timber are 

 much inferior to those of all the other hickories. 



The Mountain Ash Tree. Pyrus* 

 Mit. Ord. Rosaceae. Lin. Sijst. Icosandria, Di-Pentagynia. 



The European Mountain ash {Pyrus aucuparia,) is an 

 elegant tree of the second size, with an erect stem, smooth 

 bark, and round head. The leaves are pinnated, four or five 

 inches in length, and slightly resemble those of the ash. The 

 snow-white flowers are produced in large flat clusters, in 

 the month of May, which are thickly scattered over the 

 outer surface of the tree, and give it a lively appearance. 

 These are succeeded by numerous bunches of berries, which
