The writer has realized for some little time that the value of the relatively large number of articles on the scientific phases of archery would be increased if they could be unified and reviewed in language deliberately non-technical. In preparing the present article, he has had in mind the average archer as he knows him from numerous personal contacts—a splendidly intelligent, enthusiastic devotee of the bow, who has followed other courses than science and engineering in his life's work. His interest in archery is great. It is the writer's greatest hope that this presentation will give the above-pictured average archer a fairly clear idea of "what it's all about," and enable him to find his way without difficulty through those of the original papers that may interest him.
