A series of experiments in which true-prairie grasses were clipped at frequent intervals afforded excellent materials for a study of the effects of such treatment upon the food reserves. Two species of Andropogon, at present the most important dominants of true prairie, were employed. A series of quadrats on a north-facing slope in the Blemont prairie in Lincoln, Nebraska, in which little bluestem Andropogon scoparius, grew in about 70 of big bluestem, A. furcatus, were obtained about a mile distant from virgin lowland prairie near the flood plain of salt creek.
