almost at will, and introduce new factors as fancy suggests. The imagination makes what it will of chairs, blocks, leaves, chips, if they serve the purpose of carrying activity forward.
From a very early age, however, there is no distinction of exclusive periods of play activity and work activity, but only one of emphasis. There are definite results which even young children desire, and try to bring to pass. Their eager interest in sharing the occupations of others, if nothing else, accomplishes this. Children want to "help"; they are anxious to engage in the pursuits of adults which effect external changes: setting the table, washing dishes, helping care for animals, etc. In their plays, they like to construct their own toys and appliances. With increasing maturity, activity which does not give back results of tangible and visible achievement loses its interest. Play then changes to fooling and if habitually indulged in is demoralizing. Observable results are necessary to enable persons to get a sense and a measure of their own powers. When make-believe is recognized to be make-believe, the device of making objects in fancy alone is too easy to stimulate intense action. One has only to observe the countenance of children really playing to note that their attitude is one of serious absorption; this attitude cannot be maintained when things cease to afford adequate stimulation.
When fairly remote results of a definite character are foreseen and enlist persistent effort for their accomplishment, play passes into work. Like play, it signifies purposeful activity and differs not in that activity is subordinated to an external result, but in the fact that a longer course of activity is occasioned by the idea of a result. The demand for continuous attention is greater, and more intelligence must be shown in selecting and shaping means. To extend this account would be to repeat what has been said under the caption of aim, interest, and thinking. It is pertinent, however, to inquire why
