A happy effect of the present stress is found in the growing _rapprochement_ between the missions of a given national group, and to a less extent between those of different nations. This is due to the necessity for coöperation in order to make a reduced force serve for the needs of an increasing work. In a few cases already a desire to economize resources has led to readjustment of fields; in others to a temporary filling of vacant places by missionaries of a different denomination or nationality. The home constituencies are thus being taught the beautiful lesson of the trenches as related to true brotherhood and essential Christianity. Perhaps one of the best discussions of this war as affecting the international and interconfessional relationships of missions is that of Dr. J. Schmidlin, a Roman Catholic professor of theology in the University of Münster, found in _The Constructive Quarterly_ for December, 1915, from which we quote two sentences: "Thus that which has served to separate missionaries who were comrades in belief and confession--national solidarity and love of country--has also united and reconciled children of the same country who were separated in their belief. Surmounting all barriers of dogma and church polity, men have learned to love and cherish one another, yes, even to recognize that in spite of all that separates us there is much also that binds us together." Turning now from the effect of the war upon missions, a few paragraphs may be devoted to considering post-bellum reconstruction in mission lands. The Germans, even more than the Allies, are diligently studying the many problems and possibilities of changes necessitated by the readjustments that must surely come. The economic waste of the past four years is almost inconceivably great; and to restore this waste puts upon every nation an amount of production vastly greater than any known in the past. Raw material, freedom of the seas that the manufacturing countries may buy from every land and carry back for sale and distribution the manufactured products, a new enlistment of labor in countries where climate and primitive living make work irksome and unnecessary, an uplift in desires and ideals that new markets may be created, increasing intelligence and friendliness so that coöperation may be willing and profitable--these are some of the essentials of progress after the war.
