WALKING tours are popularly supposed to be feasible chiefly for those to whom this method of travel is incidental to their occupation-timber cruisers, landlookers, prospectors, game wardens and trappers of the North-men who daily match themselves against the forces of Nature. To the average city man rarely does it occur that by substituting walking, our most natural means of locomotion-even if carried no farther than the daily to and from business trip-for the rapid transportation perfected in our modern industrial life he can attain better business efficiency and an increased physical and mental well being.
