AN HISTORIC MOMENT IN MOTION PICTURES
D. W. Griffith, setting his natural stage for a "long shot" in his epoch-making photoplay, "Birth of a Nation." The director is in consultation with Civil War veterans to insure the accuracy of the battle scene he is about to film. The long shot was invented by Griffith and first used in this picture.
