Harvard University has not received a more splendid tribute for its spirit and its labor in the great war than the message from the law students of the University of Buenos Aires published in this morning's CRIMSON. It was not so long ago that we Americans felt it would be difficult for South America and the United States ever to come into close harmony. National and temperamental differences seemed so strong that a unity of purpose on the Western Hemisphere was looked upon as a distant dream. Such differences, however, melt away when a question of duty to do the right clearly presents itself. As a poet has said, border, breed or birth are small matters in such a contingency. It is a glorious thing to know that through the awful destruction and havoc which this war is effecting we are at least coming to know, to understand, and to appreciate our brothers of the South and that they are seeing us in another light than that of rank materialists. No shallow sentiment or diplomatic sophistry prompted this letter from the law students of Buenos Aires. It was the expression of opinion of a class of men who think and whose thought is all the more to be trusted because of their study. Such a sincere statement will be of great help to us all in a time when even the most thoroughly convinced has his moments of doubt.
