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.
