Review of the work of W. J. McGee on ground‐water levels

W J McGee was a scientist of broad‐interests, large vision, and unbounded enthusiasm for science and its application to human welfare. He was one of the earliest champions of the conservation of our natural resources. He rose from humble origin, by rigorous self‐discipline, to outstanding national leadership. He was absorbed by zeal for service to mankind. His life had a heroic quality, as is well portrayed in the sympathetic and interesting memoir by F. H. Knowlton (Geol. Soc Amer. Bull., v. 24, pp. 18–29, 1913).
