Total chlorophyll was photometrically determined for bark samples taken from the four cardinal compass points of 20 American beech trees (Fagus grandifolia). Chlorophyll concentration was equal or in excess of published values for trembling aspen (Populus tremuloides) and varied with bark aspect. Bark from the S of the trees contained the greatest total chlorophyll; bark from the N of the trees, the least; and intermediate amounts were contained in bark from the E and W
