Feb 5-1924. Tuesday, Tuesm. Today at 11.40 A.M. gave my first lecture to about 20 Mining Engineers. Had to do with Inorganic and Organic Matter. The young men were much interested and I had their attention to the end. One man said to me "It is evident that I shall learn much from your course of strict Geology."
