II. Maneuvering. (Infantry, artillery, and tanks.) 



Physical character of surface formation, including seasonal varia- 

 tions; river crossings; interpretation of maps. 



III. Water resources. 



Distribution of springs; underground water; volumes of streams 

 with seasonal fluctuations. 



IV. Transportation. 



Road metal; railroad ballast; depth to hard rock; stability of 

 slopes; river crossings. 



V. Construction. 



Material for concrete ; building stone ; stability of slopes ; character 

 of foundations. 



VI. Mineral resources. 



Mineral fuels in theatre of operations ; location of centers of enemy 

 mining industry; mineral resources of enemy. 



VII. Earth telegraphy and listening-in devices. 

 Determination of localities of favorable geologic conditions. 



VIII. Camps, cantonments, aero fields. Munition and engineer 

 dumps. 



Drainage and character of soil and subsoil, as well as water supply. 



IX. Areas of possible artificial inundation. 

 In part based on geology. 



As in all other fields of applied geology the first essential for its mili- 

 tary use is a geologic map. A geologic map once made with necessary 

 structural sections and tables of sequence can be interpreted for the 

 various military uses above referred to. Should warfare continue to 

 develop on the scale and with the scientific refinement witnessed by 

 the last five years, geologic maps will in time be considered almost 

 as essential to offensive and defensive operations as are topographic 

 maps. 



It is evident that the use of geology must be considered a part of the 

 preparations for war. Such preparation will take account of the follow- 

 ing propositions : 



1. The general principles of geology and their application to war 

 must be made a part of military education. 



2. Peace-time preparation should include the collection and coordi- 

 nation of geologic data relating to all possible theatres of operation. 



3. A staff of geologic engineer reserve officers should be organized. 

 It should be selected from experienced professional geologists and should 

 receive a special peace-time training necessary to develop its full useful- 

 ness when called into active service.
