“That depends upon the species,” replied Cecil. “One of the giant trees in the Sequoia National Park was undermined by a creek a short time ago and fell. That, as you know, was a Redwood. They made a cross section of that tree seventy feet above the base and it measured eleven feet in diameter. The tree was 280 feet tall and had a base diameter of twenty-one feet. The annual rings showed it to be 1,932 years old. Of course those trees are the oldest living things in the world.
