But what have been the effects of this war upon the home base of missions? The financial drafts made by the governments and voluntary organizations of warring nations upon their peoples and the increased cost of everything have affected the treasuries of some of the smaller societies unfavorably. For the most part, however, the mission boards have not only met their expenses but in many cases receipts have been larger than ever before. The contributions thus given have called attention to missions as being both worthy and indispensable elements in the world situation, and hence necessitating their support. Perhaps this is felt most generally among friends of British missions. Man power causes the societies greater difficulty. Practically the entire German force has been sent from India, or else interned, and to fill their places has made new demands upon other nationalities. The depleted ranks of French societies have not been filled. Great Britain needs all her men for the trenches and has been sorely pressed in trying to supply the foreign fields with the workers absolutely required. Even the United States, since her entry into the war, is experiencing difficulty in keeping missionary candidates from going to the front in Europe instead of re-enforcing the thin Asiatic and African battle lines. Hope for improvement in this recruiting is slight, since the call to arms has laid strongest hold upon college and university men. Thus in 1915, out of 52,000 students in German universities, 41,000 were under arms; in France all students except those physically unfit were called out; in Great Britain and Ireland about 50 per cent of the male students were in the army or navy, in Canada 40 per cent, and in Australia 30 per cent.[11] In the United States volunteering and the draft have emptied the colleges and universities of practically all the choicest men of twenty-one and upward. If this continues long, an interim must ensue before another college generation furnishes a sufficient number of missionary candidates. Yet it may be expected that the present devotion to a cause that ends so commonly in death or lifelong crippling will end forever the old excuse urged against missionary enlistment, that the service is a hard one and often fatal, in certain unhealthful countries. Men will join the colors of the Prince of Peace and of Life even more willingly than they now march under the banners of destruction and death in the hope of establishing once more justice, righteousness and lasting freedom in the earth.
