EVERY month this period is devoted to matters concerning the Girl Guide Movement-a Movement which has steadily gathered new strength and new influence since the moment of its foundation. This evening Dame Katharine Furse , Assistant Chief Commissioner of the Guides, will talk on a topic which lies at the very root of the whole Scout and Guide Movement, whose twin foundation may be said without exaggeration to be intelligent use of the eyes and fresh air. And a talk on such a subject comes at a highly appropriate time, for all Girl Guides are now full of excitement at the prospect of their summer camps. Many hints the Assistant Chief Commissioner will be able to give to Guides which will help them to find new joys during their ' hikes.'
