"The Book of Sports: Containing Out-door Sports, Amusements and Recreations, Including Gymnastics, Gardening & Carpentering" by William Martin has the goal to induce and to teach boys and girls to spend their hours out of school in a way that they are able to gain innocent enjoyment while they also promote their own health and bodily strength. It has rules, descriptions, and ideas for outdoor activities that allow children the chance to keep themselves entertained in the fresh air.
