If Archer is a little overcautious in taking human life in _The Green Goddess_, the law of averages still prevails, for Eugene O'Neill has made up the deficit in _Diff'rent_ by rounding off his little play with a double hanging. This tragedy, described on the hoardings as "a daring study of a sex-starved woman," has much of O'Neill's characteristic skill in stage idiom, but it is much less convincing than the same author's _The Emperor Jones_. Indeed _Diff'rent_ is essentially a reflection of the other play, in which O'Neill states again in other terms his theory that man is invariably overthrown by the very factor in life which he seeks to escape. Emma of _Diff'rent_, like the Emperor Jones, completes a great circle in her frantic efforts to escape and, after refusing a young man, because of a single fall from grace, comes thirty years after to be an eager and unhappy spinster who throws herself at the head of a young rascal. With the growth of realism in the drama, criticism has become increasingly difficult, since the playwright's apt answer to disbelief on the part of the critics is to give dates, names, addresses and telephone numbers. "Let the captious be sure they know their Emmas as well as I do before they tell me how she would act," says O'Neill menacingly to all who would question the profound truth of his "daring study of a sex-starved woman." Of course, the question is just how well does O'Neill know his Emmas, but this is to take dramatic criticism into a realm too personal for comfort. Seemingly, O'Neill and the other daring students of sex-starvation are well informed. Into the mind of the woman of forty-five they enter as easily as if it were guarded by nothing more than swinging doors. Or perhaps it would be better to describe it as a lodge room, for not all may enter, but only those who know the ritual. This is annoying to the uninitiated, but we can only bide our time and our protest until some one of the young men takes the next step and gives us a complete and inside story of the psychology of maternity.
