In order that the geologists of this country should all be 
properly represented at the next Congress by their national 
committee, it is necessary that they should assist that committee 
as much as possible by communicatin® their views. They are 
earnestly, requested to do so, and in case of their failure they 
will have themselves to blame if their views are overlooked.
