. It is currently considered by many to be the fifth largest tree in the world. Wendell Flint, in his book "To Find The Biggest Tree", Sequoia Natural History Association (2002) stated that the Lincoln Tree has a volume of 44471 cubic feet (1,259.3 m³). However, White and Pusateri, in "Sequoia and Kings Canyon National Parks", Stanford University Press (1949) indicated that the volume of the Lincoln Tree based on measurements made in the 1930's is 51000 cubic feet (1,444.2 m³), which would make the Lincoln Tree the second largest tree in the world, after the General Sherman Tree. Wendell Flint was somewhat critical of the earlier measurements and he stated that he thought that it was appropriate to exclude a portion of the irregular base of the tree from his volume calculations, which in addition to some extrapolation differences from the earlier measurements, explains the smaller volume of 44471 cubic feet (1,259.3 m³) that he obtained compared to the earlier figure. Although he chose to exclude it, Flint stated that the excluded portion of the base could just as easily be included in the calculations, presumably leading to the alternative volume of 51000 cubic feet (1,444.2 m³) The Lincoln Tree has a maximum base diameter of 36.4 feet.
