Sooner or later all European authors of note visit America, then return home and wax literary about what they have seen. Mr. Lennox Robinson is no exception and the dramatic fruits of his trip to these shores is being presented this week by the Harvard Dramatic Club in Brattle Hall in a play called "Ever the Twain."

There are two major faults in this drama. First, the story concerns what happens to a number of visiting lecturers in this country, a hackneyed theme that has been handled more effectively by Rachael Crothers. Second, Mr. Robinson forgets that in a satire the first duty of an author is to be consistently and persistently satiric. When he remembers this simple fact "Ever the Twain" is an amusing play, and, fortunately, these moments come with sufficient frequency to prevent it from becoming boring; but in the stretches in between the high spots it is pretty dull stuff.

The production, on the whole, is a very good one, and most of the faults are due to inherent flaws in the play and incompetent direction, which increased rather than alleviated them. Two things, however, stand out. One is the uniform excellence of the sets; the other is the acting of Lois Hall, who literally steals the show and turns in an impressive performance in a difficult part. Louise Graham is very good indeed, Richard Sullivan beams his way through none too convincingly, and Elisabeth Morison apparently cherishes a delusion that she is in the Moscow Art Theatre. The rest of the cast was undistinguished but adequate.

Another performance of "Ever the Twain" will be given this evening at the same time at Brattle Hall, where tickets may be obtained.
