delicacy of flavor by careful cultivation, as greatly to 
surpass the European walnut, for the table. This result 
will probably be attained by planting the nuts of the finest 
varieties found in our woods, in rich moist soil, kept in 
high cultivation ; as all improved varieties of fruit have 
been produced in this way, and not, as many suppose, by 
cultivating the original species. These remarks also 
apply to the Pecan-nut ; a western sort, which thrives well 
in the middle states, and which produces a nut more 
delicate in flavor than any other of this continent. 
These trees form strong tap-roots, and are, therefore, 
somewhat difficult to transplant ; but they are easily 
reared from the nut ; and, for the reason stated above, this 
method should be adopted in preference to any other, 
except in particular cases. 
The principal species of the hickory are the following : 
The Shellbark hichory ( C . alba), so called on account 
of the roughness of its bark, which is loosened from the 
trunk in long scales or pieces, bending outwards at the 
extremity, and remaining attached by the middle ; this 
akes place, however, only on trees of some size. The 
eaves are composed of two pair of leaflets, with an odd or 
terminal one. The scales which cover the buds of the 
Shellbark in winter, adhere only to the lower half, while 
the upper half of the bud is left uncovered, by which this 
sort is readily distinguished from the other species. The 
hickory nuts of our markets are the product of this tree ; 
they are much esteemed in every part of the Union, and 
are exported in considerable quantities to Europe. Among 
many of the descendants of the original Dutch settlers of
