In the Calaveras grove there are four trees over 300 feet in height, the tallest of which as measured by the Geological Survey is 325 feet.

The very largest that I have yet met in the course of my explorations is a majestic old fire-scarred monument in the Kings River forest.

It is thirty-five feet and eight inches in diameter inside the bark, four feet above the ground.

It is burned half through, and I spent a day in clearing away the charred surface with a sharp ax and counting the annual wood-rings with the aid of a pocket lens.

I succeeded in laying bare a section all the way from the outside to the heart and counted a little over four thousand rings, showing that this tree was in its prime about twenty-seven feet in diameter at the beginning of the Christian era.
