THIS is the first of a series of four talks in the nature of helpful suggestions for week-end holidays—two of which are to be given by Mr. Simpson, and two by Mr. A. B. B. Valentine. We are all becoming more and more additted to the ' week-end habit,' aided thereto both by the facilities offered these days for quick travel and by the increasing distaste in most of us for a week-end under urban conditions. Mr. Simpson's talks will deal more particularly with week-ends given over to walking-not only within near distances of London, but also in parts of the country further afield.
