24 FOREST-TREES OF THE UNITED STATES. 
United States. This is more limited in range than the preceding. In 
Pennsylvania, New York, and New England, it probably attains its 
greatest perfection. It is a smaller tree than the Black Walnut. It is 
also found in the Western States. The wood is of a light-brown color, 
fine-grained, and easily worked. Although less valuable than the Black 
Walnut, the wood is well adapted to many uses. The nuts are not as 
highly esteemed as those of the Black Walnut. 
No. 254. Juglans Californica, S. W.—California Walnut.—California. 
The California Walnut attains, in favorable situations, a height of 50 to 
75 feet, and a diameter of 2 to 3 feet. It does not seem to be abun- 
dant, and we know nothing respecting the value of its wood. It has 
recently been distinguished as a different species from the walnut of 
Arizona and New Mexico. 
No. 255. Juglans rupestris, Eng.—Small Black Walnut.—Texas and 
Arizona. 
No. 256. Carya oliveformis, Nutt.—Pecan-nut.—Mississippi Valley. 
This tree grows in the valley of the Mississippi and its tributaries, on 
the Arkansas, the Missouri, the Illinois, the Wabash, and the Ohio, for 
some two hundred miles above its mouth. The wood is coarse-grained, 
heavy, and compact. It is a beautiful tree, with a straight and well- 
shaped trunk. The nut is well known in the markets, and is thought by 
some to be superior in flavor to any other nut known. 
No. 257, Carya alba, Nutt.—Shell-bark Hickory.—Eastern United 
States, Thisspecies becomes a lofty tree, 80 feet high, with a diameter 
sometimes of 2 feet. Itis oneofthe most valuable of the hickories for 
timber and for fuel. It furnishes most of the hickory-nuts of commerce. 
They are pleasant-flavored and highly esteemed. On large trees, the 
bark shells off in long narrow plates, whence the common name of the 
tree. The wood is heavy, elastic, and strong, and for handles of axes 
and agricultural implements, and many other uses, it is unequaled. 
There is little difference in the quality and value of many of the different 
species of hickory.

to be inferior to the preceding species, and the nuts are thin-shelled 
bitter, and worthless. 
No. 261. Carya porcina, Nutt.—Pig-nut Hickory.—Eastern United 
States. A large tree, with small pear-shaped fruit, the nuts bitterish 
and unpalatable. The wood is tough and valuable.

United States. 
No. 263. Carya myristiceformis, Michx.—Nutmeg Hickory.—Southern 
States. This species grows in swamps in the Southern States. The

A species growing in Swamps in the Southern States, with astringent,
