Hickory nuts, sweet and bitter.
Hickory-Nuts
In gathering hickory-nuts you must be able to distinguish between the edible variety and others that are fair on the outside but bitter within. There are nine varieties of hickory-nut trees, and in general appearance they are alike. All have compound leaves and the leaflets are larger and fewer to the stem than the walnut, usually numbering from five to eleven. The nuts grow in small clusters as a rule, often in pairs, and the outer husk separates when ripe into four pieces, allowing the nut to drop out clean and dry. The full-grown tree is of good size and is found almost everywhere in the United States.
Shellbark. Shagbark
The shellbark or shagbark hickory-nut is one of the best. The flavor, as every one knows, is sweet and pleasant. It is the bark of the tree that gives it the name of shagbark, for it separates into long, ragged strips several inches wide which generally hold to the trunk at the middle and give it an unkempt, shaggy appearance.
Mockernut
The mockernut is the hickory-nut with a dark, brownish-colored shell, hard and thick and not easily cracked. It is called the mockernut because while the nut is large, usually larger than the shellbark, the kernel is very small and difficult to take out of the thick shell.
