SCIENTIFIC PLAY FOR CHILDREN (PDF)
This article outlines rules for playing tag, based upon rules adopted by the International Playtime Committee on Juvenile Sports. It took me a minute to realize that this article is not serious, but is an example of turn-of-the-last-century humor. Here are some of the rules:
I. — Tag is a game in which three or more players try to touch each other, not for money, but for fun, and with their hands.
II. — It may be played by any child over two and under ninety who is strong in wind and limb, and who has the time to devote to it.
III. — The player who is appointed by lot to touch the others is called “IT.” He should be able to stand on his feet and run if he is to be at all expert in the game.
It goes on to explain Rule XI, which describes the end of the game as “when all the players are out of breath.” Rule XII admonishes against playing in a parlor full of Chippendale furniture. And Rule XIII explains that there are no winners in tag, only a loser.
