The process of educating public opinion in their favor was slow, for it is difficult to make men see that the children of a modern city have different needs from the country or village children of a generation ago.

Men remember their own boyhood, and scoff at the idea of organized and supervised play in a made playground.

Women have no memories of the old swimming-hole.

They simply see the conditions before them, and they instinctively know what must be done to meet them.

The process of educating the others is slow, but this year in Philadelphia sixty public schoolyards were opened for public playgrounds, and the city appropriated five thousand dollars towards their maintenance.
