are very small, and extremely hard. 
Description, §c. The pig-nut hickory is a lofty tree, 70 ft. or 80 ft. high, 
with a trunk from 3 ft. to 4ft. in diameter. In winter, when stripped of its 
leaves, it is easily known by the shoots of the preceding summer, which are 
1273 
brown, less than half the size of those of C. alba and C. tomentésa, and ter- 
minated by small oval buds. C. porcina has scaly buds, which are more than 
lin. in length before they unfold. The inner scales, which are large and 
reddish, do not fall off till the leaves are 5in. or Gin. long. The leaves 
generally consist of three pairs 
of leaflets, and an odd one. 
The leaflets are 4in. or 5in. 
long, acuminated, serrated, 
nearly sessile, and glabrous on 
both sides. On vigorous trees 
which grow in shady exposures 
the petiole is of a violet colour. 
The catkins are about 2 in. 
long, smooth, flexible, and pen- 
dulous. The female flowers 
are greenish, and situated at 
the extremity of the shoots: 
the fruit which succeeds them 
is frequently produced in pairs. 
The husk is thin, of a beautiful 
green ; and, whenripe, it opens 
through half its length for the 
passage of the nut, which is 
small, smooth, and very hard, 
on account of the thickness 
of the shell. The kernel is 
sweet, but meagre, and difficult to extract, from the firmness of the partition. 
These nuts, in America, are never carried to market, but serve for food for 
swine, racoons, and numerous squirrels which people the forests. (Miche. 
N. Amer, Syl.,i. p. 169.) This tree is found in the middle, western, and 
southern states, on the borders of swamps, and in places which are wet, 
without being marshy. It has been observed, that the mocker-nut is always
