Once again the Vagabond finds a group of special lectures to lure him forth from his cozy construction shack in the Lowell House yard into the cool of the evening air and the aloofness of Harvard Yard. The week's extra-curricular lectures open rather appropriately with "The Wandering Scholars and Mediaeval Latin Songs" by Professor Hilka of the University of Gottingen. Professor Hilka's discussion is scheduled for five o'clock this afternoon in Emerson D.

Tomorrow at four-thirty in Pierce Hall Mr. Stedman S. Hanks will lecture on "The Flying Boat", a topic of interest to all those who are air minded and yet possessed of a sixth sense--the call of the sen. At five o'clock on the same day the first lecture in a series, "The Nature of the Visual Process", will be given by Professor Hecht of Columbia University who will talk on "Visual Acuity" in Building C, of the Medical School, Longwood Avenue, Boston.

Tuesday night at eight in Fogg Museum Professor Garrod of Oxford University will lecture on "Matthew Arnold as Critic": This lecture on the great Victorian may well be of particular interest to those vagabonds who find themselves aware of the literary influences sometimes called the New Humanism.

The calendar for the balance of the week is equally attractive, and the Vagabond will report on it tomorrow morning if Mr. Vallee's new book is not too intriguing.
