Abstract

"A tree that has lived several thousand years, if it can tell its story, may well bear historical evidence of climate changes. There is great variation in the diameters of the annual rings. On a cross section of a Sequoia gigantea there are places where a hundred or more rings may be found within the compass of an inch, and other places where the annual ring is an eighth or even a quarter of an inch in diameter. What has caused this difference?"
