" THE love-affair of Enid Challenger and Edward Malone is not of the slightest interest to the reader, for the simple reason that it is not of the slightest interest to the writer. The unseen, unnoticed lure of the unborn babe is common to all youthful humanity. We deal in this chronicle with matters which are less common and of higher interest. It is only mentioned in order to explain those terms of frank and intimate comradeship which the narrative discloses. If the human race has obviously improved in anything —in Anglo-Celtic countries, at least —it is that the prim affectations and sly deceits of the past are lessened, and that young men and women can meet in an equality of clean and honest comradeship. "
