The committee in charge of exhibits was erected in recent years for the obvious purpose. Committee reports were preserved for 1938 and 1939 when Stephen Thomas was Secretary and H. T. Green acting Secretary. A few of the papers relate to museum groups, while many of them refer to the display of minerals under the supervision of S. G. Gordon, 1935-46. Finally various papers are assembled with the inclusive dates of 1868-1940 which carry the names of W. S. W. Ruschenberger, E. J. Nolan, and Wharton Huber.
