Excerpts of the President's News Conference
There is very little that is new, as I understand it, in the arbitration treaty that was recently signed with France. I regard all treaties of that kind as of importance, as signifying the peaceful intent of the countries involved and the declaration made in the solemn method of a treaty of the desire to adjust all differences by negotiation, conciliation and arbitration. In a way, they provide a method before controversies arise by which controversies may be adjusted.
