This tree grows to the height of eighty or ninety feet, with a circumference of from six to eight feet, and preserves its thickness from forty to fifty feet. It is found in rich bottom-lands. Rock chestnut oak is one of the varieties of this tree; its wood is so heavy as to sink in water. Swamp white oak is another variety of this tree. It is very marked, and is found farther north than the chestnut oak, and its wood is of much better quality.
