initiative, there was created a Joint Information Board on Minerals and Min- 

 eral Derivatives, on which were represented more than thirty boards and 

 bureaus. 



Problems of the domestic petroleum supply for war purposes received par- 

 ticular attention. Careful estimates of the country's oil resources were made 

 by oil and gas geologists. At the same time exploration by drill was carefully 

 followed and every effort made to extend assistance. The search for undis- 

 covered pools was pushed vigorously. Thus, with the cooperation of the Ad- 

 ministration of Indian Affairs, it was possible, in Oklahoma, by examinations 

 and publication before leasing, to cause drilling to be concentrated in places 

 where conditions were most favorable for large production. 



In short, the Survey has supplied necessary information ; it has carried on 

 investigations of various sorts to obtain specially needed information ; it has 

 given technical advice to the Government in the capacity of consulting geolo- 

 gist, and it has supplied personnel to other organizations.

MILITARY CONTRIBUTION OF CIVILIAN ENGINEERS 

 BY GEORGE OTIS SMITH 



i Abstract) 



The original distinction between military and civil engineers has gradually 

 lost its force. Growth in civil engineering has resulted, and thus have arisen 

 a variety of engineers in the civil service of the Government. 



Cooperation of the United States Geological Survey with the Army in mili- 

 tary mapping. Memorandum suggesting a reserve corps of engineers. Legis- 

 lation of 1916. Utilization of civilian organizations in engineering work and 

 commissioning of engineer officers for military service overseas.

PRESENTATION OP GEOLOGIC INFORMATION FOR ENGINEERING PURPOSES 

 BY THOMAS WAYLAND VAUGHAN ^ 



(Abstract) 



The author first made a summary statement regarding requests for certain 

 kinds of information on cantonments addressed by Army and Navy officials to 

 the United States Geological Survey. These requests were classified under 

 four topics, as follows: (1) Selection of sites, (2) nature of foundations, (3) 

 material for highway construction, (4) water supply. 



The services a geologist may render in the selection of sites was illustrated 

 by three instances. In the account of the selection of one site, that for the 

 artillery range and cantonment, named Camp Bragg, near Fayetteville, North 

 Carolina, particular emphasis was laid on the value of knowledge of the general 

 features of the country, because by such knowledge efforts will not be wasted 

 on searches within areas in which there are only unsuitable tracts, but will be 

 restricted to areas in which conditions are favorable for the project in mind. 

 Mention was made of information furnished on the foundation for a radio
