Instructive, above all things practical, this book is based upon experience, whose aim is to show boys how to do accurately all manner of out-of-door things within their powers. Beginning with the backyard, detailed information is given for such contrivances as pet shelters, windmills, aërial toys; going farther afield the interest centers in coasters, skees, kites, fishing tackle, etc.; then come boat building and boat management; while the fourth part of the book is devoted to camps and camping, tree-huts, brush-houses, etc.
