ACTIVITIES OF MEMBERS DURING WORLD WAR 27 



GEOLOGISTS. 



Two geologist nienihers were engaged in V. M. C. A. work for 

 the Army, one in France, one in America. Three were on the staff 

 of the U. S. Geological Survey and were detailed to the War De- 

 partment for topographic mapping, while two men prepared data on 

 oil and gas production, as well as doing map work. Three members 

 prepared bulletins on as many of the training camps. Another was 

 Assistant Director of the U. S. Bureau of Mines for the period of 

 the war. Iowa clays were examined by geologists of the State Col- 

 lege to find substitutes for imported fire clays. Several geologists 

 served as instructors in the S. A. T. C. at difTerent schools and aided 

 in various ways in the preparation of soldiers and civilians alike for 

 their part in winning the war. 



CHEMISTS. 

 Several chemists were able by their technical training to render 

 distinct service in specialized work, as for instance the treatment of 

 underwear to render it vermin proof, the preparation of chemicals 

 needed in warfare, the inspection of ordnance, the analysis of 

 water for the Camp Dodge supply. Others were of service in 

 directing the four-minute men and in similar patriotic service. 



BIOLOGISTS. 



Several of the biologists of the Academy were directly engaged 

 in furthering increased food production in various ways — in fighting 

 injurious insects and plants, in doing specialized laboratory work, 

 in stimulating the raising of special crops. One member was in 

 Red Cross work in England, another by his studies produced a poison 

 gas detector and a number were engaged in S. A. T. C. instruction 

 in various capacities. In addition a number were in the army. 



BOTANISTS. 



During the war an active campaign was carried on looking to- 

 ward the extermination of the barberry. The U. S. Government 

 detailed several members of the Academy for this work in Iowa. 

 Also work was done trying to eliminate the loss of crops by the 

 destruction of weeds. Some members of the Academy were engaged 

 in trying to save and utilize wood and fuel and some work was done 

 in connection with the utilizing of walnut and other timber for 

 gunstocks and aeroplanes. 



Other members were actively engaged in assisting by their techni- 

 cal knowledge the increase of food production so necessary during 

 and after the war. One member, whose intimate acquaintance with 

 the foreign-born element of our population gave him ready access
