"The Frontier" is that old idea of the conflict between the old and the new, between fathers and sons, between the intense convictions of yesterday and to-morrow. The form which Le Blanc recreates it is that of the conflict between devotion to country and devotion to that latest ideal, world-wide Peace. The father is a rugged old French patriot who fought in the war with Germany, whose heart is still bitter, and whose hate flames quickly at the thought of Alsace and Lorraine. The son is a professor of history whose studies have taught him how vain are bloodshed and violence.
