the moment, the notorious provincialism and "intramuralism" of our colleges is standing us in good stead. There will be enough confused running to and fro for a time yet, without a few thousand more college boys added to the throng. But from now on it will be an increasing problem for our educational institutions to

convince their students that the things they are now doing are worth while, immediately as well as ultimately. It will be harder and harder to persuade them of the pertinence of the letter of the President of the United States, which we published in the October, 1940, number of the JOURNAL.
