“ We must learn that some trees, like oak, sugar maple, dogwood, ash, cherry, walnut, beech, and elm are very hard and that most of the evergreens are soft, such as spruce, pine, arbor vitae, as well as the poplars and birches. It is easy to remember that lignum vitae is one of the hardest woods and arbor vitae one of the softest. Some woods, like cedar, chestnut, white birch, ash, and white oak, are easy to split, and wild cherry, sugar maple, hemlock, and sycamore are all but unsplitable. ”
