The accompanying note has been prepared as a result of the published papers on “mountain-building” in the Bulletin of this Society for 1923, and it may be considered as a natural continuation of the discussions in that symposium. Much assistance also has been derived from a consideration of the recent papers by R. A. Daly,2 H. A. Brouwer,3 F. B. Taylor,4 W. Bowie,5 and W. D. Lambert.6
