One of the exercises which assists in attaining the end here in view, we have already alluded to, as being successfully employed by Nature for the purpose,--that is, the child's play. Any amusement which requires thought or attention, is well calculated to answer this purpose,--and if the child can be induced and trained to speak and play at the same time, his thinking powers being occupied by the external use of his toys, the end of the teacher will in so far be gained. Questions put to a child at that time, and answers given by him while he continues to exercise his mind upon his amusements, will prepare the way, and greatly assist in giving him the power of exercising it upon ideas, without the help of these external and tangible objects. The principle in both cases is the same, although in the one it is not carried out to the same extent as it is in the other. And here we cannot help remarking, how extensive and important a field the working of this principle opens up to the ingenious toy-man. If a game, or games, can be invented, where the child must have his attention occupied with one object, while he is obliged to answer questions, or to make observations, or to detail facts, or in any other way to employ his speaking powers extemporaneously, (not repeating words by rote,) the person who does so will greatly edify the young, and benefit the public. Another method by which the principle may be called into exercise, is to tell a short story, or simple anecdote, and then to require the child to rehearse it again. In doing this, the mind of the child is employed in communing with the memory, while he is engaged in detailing to the teacher or monitor, the special circumstances in their order. Upon the principles of individuation and grouping, too, (the two most important principles, be it observed, which Nature employs with young children,) we can perceive, that it will be much easier for the child, and at least equally powerful in producing the effect, if the teacher or parent shall confine himself to one or two stories or anecdotes at a time, till, by repeated attempts, the child can in its own words, and in its own way, readily and fluently detail the whole of the circumstances to the parent or teacher, whenever required.
