THE Le Play Society's well-known “Discovery” chart has been revised and enlarged and its subject-matter has been put into pocket-book form with blank leaves for maps and notes. In this form it is published under the title “Exploration” at 4d., postage Id. It directs attention to some hundreds of possible fields of local exploration grouped under the major headings: geology, rivers and water-supply, weather and climate, vegetation and open spaces, agriculture, zoology, archaeology, history, communications, occupations, folk-lore, place-names, modern and changing conditions, camping and rambling. It is calculated to stimulate youthful zest for exploration and arouse and develop scientific curiosity. An ethical aim is provided by the following passage, appearing on the front page, reminiscent of the teaching of Patrick Geddes and Victor Branford: “If you learn to know your own place well, and in so doing learn to love it more, it will help you to understand and appreciate other places, and to sympathise with their problems”. It should prove serviceable to scoutmasters and girl-guides as well as to others engaged in the teaching of local history, local geography and civics and in training for citizenship.
