DECIDUOUS TREES. 355 



good portrait of the finest hickory of this species we know of in this 

 country, growing on the farm of Sylvanus Purdy, Esq., in Rye, N. Y., 

 near the village of Mamaroneck. It is about eighty feet high, ninety 

 feet across the spread of its branches, and has borne fourteen 

 bushels of shelled nuts in one season ! The upright growth on the 

 left is a part of the tree which has taken a new upright direction. 



THE THICK-SHELLED-NUT HICKORY. C. sulcata and C. tomen- 

 tcsa maxima. This is the tree which bears the large oblong nut of 

 commerce, and the thickness of its shell suggests the name. Its 

 bark is somewhat scaly, but in thicker and narrower sections than 

 that of the shell-bark hickory, and not so easy to detach from the 

 tree ; it is also much rougher on young trees. The leaves are the 

 largest of any of the hickories. Each leaf is composed of from 

 seven to nine leaflets. The nuts are squarish-oblong, from one and 

 a quarter to two inches in length, with thick yellowish-white shells, 

 but fine flavored. As an ornamental tree it has the same charac- 

 teristics as the preceding. Nuttall and Michaux describe what is 

 popularly known as the thick-shelled hickory in two species, both 

 of which we give in connection with the popular name for both. 



THE PIG-NUT HICKORY. C. porcina. This species is distin- 

 guished by its smaller leaves and fruit ; the latter not being 

 marketable, though good food for hogs, who crunch and eat the 

 shell and meat together. Its bark when quite young is smooth, 

 and then resembles the shell-bark hickory ; but about the age when 

 the latter begins to show its laminate character, the former breaks 

 into fine hard shallow furrows, and is not at all disposed to laminate. 

 Its branches are rather more numerous and straighter than the 

 other hickories ; but with age its foliage breaks into the same 

 forms, and is as fine as any of the others. Its leaves are usually 

 formed of seven leaflets, smaller and slenderer than the preceding 

 species. The foliage is also rather lighter colored, and the aspect 

 of the tree when young is less robust. It grows most naturally in 

 moist ground, and there becomes a lofty tree. 



THE BITTER-NUT HICKORY, AND THE WATER BITTER-NUT HICK- 

 ORY, C. amara and C. aquatica, are similar to the foregoing, the
