Discussion 



Dr. A. W. Gbabau : I would suggest that the workers in experimental geology 

 get out a syllabus or small text-book setting forth the present status of the 

 subject and giving methods of procedure to carry on simple experiments such 

 as require only simple apparatus ; also to suggest lines along which investiga- 

 tions can be carried on. The mass of detail accumulated ought to be digested 

 and summarized, so that the busy geologist can master it without too much 

 expenditure of time and energy.
