Work for a child must possess some variety within itself. A child does not have to know the reasons for sowing or reaping to have his interest aroused. He will readily undertake very simple actions which have an immediate end or which permit him to use some special effort. He will for example, gladly pluck weeds from paths or furrows, sweep up dried leaves or carry away an old branch. In a word, to have a field of activity and occasion for new experiences bring satisfaction to the animating spirit which prompts a child to make its way in the world.
