We have supposed one child going forward on the soft ground, while the other is slowly following him. When the foot of the first sinks, the other instantly stands still; and a spectator can perceive, better perhaps than the child himself, that something like the following mental process takes place on the occasion. The child thinks with himself, "Tom's foot has sunk; if I go forward, I also will sink; I will therefore stand still, or cross at another place." This is an exact parallel to thousands of similar instances which come under the notice of parents and others every day; and is a process quite familiar to adults who have paid any attention to the operation of their own minds when similarly circumstanced. When it is analysed, we find it to consist, as shewn in a former chapter, of three distinct parts, not one of which can be left out if the effect is to be produced. There is always, at the commencement of such an operation, the knowledge of some fact; "Tom's foot has sunk." There is, secondly, an inference or lesson drawn from this knowledge, "If I go forward, I also will sink." And there is, thirdly, the practical application of that lesson, or inference, to the child's present circumstances: "I will stand still, or cross at another place."

It is this process, or one in every point similar, that takes place in the mind, either of the young or the old, whenever they apply the facts gleaned by observation or experience for the guidance of their conduct. Now what we are at present in search of, is an exercise applicable to reading, as well as to observation;—to the school, as well as to the play ground or the parlour;—and to knowledge whose use may not be required at the instant, as well as that to which we are driven by necessity.

The desideratum here desired is to be found by the teacher in the method, now very extensively known, of drawing lessons from useful truths, and then applying them to the future probable circumstances of the pupils. For example, when a child reads, or is told that Jacob was punished by God for cheating his brother and telling a lie, the great object of the parent or teacher is to render these truths practical,—which the question, "What does that teach you?" never fails to do. The child, as soon as he knows the design of his teacher in communicating practical truths, and is asked the above question, will tell him, that he ought never to cheat his neighbour, or tell a lie. The application of these lessons, when thus established as a rule of duty founded on Scripture, is as extensive as the circumstances in which they may be required are various;—and the teacher has only to suppose such a case, and to ask his pupil, if he were placed in these circumstances, what he should do. The dullest of his children will at once perceive the duty, and the source from which he derives confidence in performing it.

There is no difficulty, as we have seen, in drawing and applying practical lessons in cases of urgency, where experience and the common sense of the individual prompt him to it;—and this attempt to imitate Nature in less urgent cases, and especially in hearing, or in the more artificial operation of reading, has been found in experience to be completely successful. We shall endeavour to point this out by a few familiar examples.

Let us for this purpose suppose, that one of the boys formerly mentioned is accompanied by his teacher, instead of his companion, and is approaching the soft ground which lies between them and the house. Before they arrive at the spot, his teacher tells him, that the marsh before them is so soft that even a child's foot would sink if he attempted to tread upon it. The boy might hear, and perfectly understand the truth, and yet he might not at the time think of the use to which it ought to be put. But if the teacher shall immediately add, "What does that teach you?"—his attention would instantly be called, not so much to the truth itself, as to the uses which ought to be made of it, and his answer in such a plain case would be ready, "We must not cross there, but seek a road to the house by some other way." Now here the fact was verbally communicated; and although the object was in sight, and the use of the fact might in some measure have been anticipated so as to suggest the answer, yet a little consideration will shew, that a similar effect would have been produced by the question, had the parties been in the house, or had the truth been derived from reading, and not from the oral communication of the teacher.

It is the want of something like this in the acquisition of truth by books, which renders that kind of knowledge in general of so little practical benefit. The truths and facts learned while attending school, are too often received as mere abstractions, without reference to their uses, or to the personal application of those uses to the circumstances of the child or his companions. Events daily occur in which the pupil's knowledge might be of important service;—but the benefits to be derived from it not having been taught, and the method of applying the facts which he has acquired by reading not having been explained,—the knowledge and its uses are seldom seen together, and the practical benefit of the teaching is accordingly lost. This at once accounts for the very remarkable circumstance, that children, and not unfrequently adults also, derive far more benefit from the scanty knowledge which they have gleaned by observation and experience, than from the many thousands of highly useful facts which have again and again been pressed upon their notice by reading and study. In almost every case Nature prompts us, as we have seen, to turn to our own benefit the knowledge which she has imparted; but as the mode of teaching reading, which is the artificial method of acquiring information, often overlooks the use we are to make of it, we remain satisfied with the knowledge itself, and do not think of its application. To illustrate this fact in some measure, let us suppose a basket of filberts set down for the use of a company of boys, and that one of them tries to crack the shells with his front teeth. He fails. But he sees his companions put the nuts farther back in the mouth, and succeed. Does he lose his share, by continuing to misapply the lever-power provided for him by Nature?—No indeed. He, by a single observation, at once draws and applies the lesson;—he immediately cracks his nuts as readily as his companions, and he continues to do so all his lifetime after. But the same boy may have, that very forenoon, been reading a treatise on the power of the lever, and might read it again and again without considering himself at all interested in the matter, or thinking it probable that he ever would. His reading, without the application we are here recommending, would never have led him to perceive the slightest similarity between the fulcrum of the lever, and the insertion of his jaw; or any connection between the lesson of the school, and the employment of the parlour:—But that would.

This is but one of a thousand examples that might be given, of the evils arising from the non-application of knowledge in reading, and which are applicable, not to children merely, but also to adults. The drawing and applying of lessons, the exercise which we are here recommending, has been found a valuable remedy for this defect in ordinary reading. The object of the teacher by its use, is to accomplish in the pupil by reading, what we have shewn Nature so frequently does by observation;—that is, to train the child to apply for his own use, or the use of others, those truths which he acquires from his book, in the same way that he does those which he derives from experience. To illustrate this, we shall instance a few cases of every day occurrence, in which the question, "What does this teach you?" when supplemented to the fact communicated, will almost invariably answer the purpose desired, whether the truth from which the lesson is to be drawn, has been received by observation, by oral instruction, or by reading.

When an observing well-disposed child sees a school-fellow praised and rewarded for being obliging and kind to the aged or the poor, there is formed in the mind of that child, more or less distinctly, a resolution to follow the example on the first opportunity. Here is the fact and the lesson, with the application in prospect. This whole feeling may be faint and evanescent, but it is real; and it only wants the cultivating hand of the teacher to arrest it, and to render it permanent. Accordingly, if on the child hearing the praise given to his companion for being kind and obliging to the poor, he had at the time been asked, "What does that teach you?" the lesson suggested by Nature would instantly have assumed a tangible form; and in communicating the answer to the teacher, both the truth and the lesson would have been brought more distinctly before the mind, and the reply, "I should be kind and obliging to the poor," would tend to fix the duty on the memory, and would be a good preparation for putting it in practice when the next occasion should occur.

Again, if another thoughtful and well disposed child sees a companion severely punished for telling a lie, the question, "What does that teach me?" is in some shape or degree formed in his mind, and his resolution, however faint, is taken to avoid that sin in future. This, it is obvious, is nothing more than a practical answer to the above question, forced upon the child by the directness of the circumstances, but which would not have so readily made its appearance, or produced its effect, in cases of a less obtrusive kind, or in one of more remote application; and every person must see, that the beneficial effects desired would have been more definite, more effectual, and much more permanent, had this faint indication of Nature's intention been followed up by orally asking the question at the child, and requiring him audibly to return an answer.

Let us once more suppose a child in the act of reading the history of Cain and Abel, in the manner in which it is commonly read by the young, and that the child thoroughly understands all the circumstances. He may be deeply interested in the story, while the uses to be made of it may not be very clearly perceived. But if, after reading any one of the moral circumstances, such as "Cain hated his brother," or after having it announced to him by the teacher, he was asked, "What does that teach you?" the practical use of the truth would at once be forced upon his mind, and he would now very readily answer, "It teaches me that I should not hate my brother." In this case also, it is quite obvious, that without such a question having been proposed, and the answer to it given, the practical uses of the truth recorded might have been altogether overlooked; and even although they had not, still the question and its answer will always have the effect of making them stand out much more prominently before the mind, and will enable the memory to hold them more tenaciously, and bring them forth more readily for practice, than if such an operation had been neglected. Hence the great importance of training the young by this exercise early to perceive the uses of every kind of knowledge, particularly Scriptural knowledge; because the habit formed in youth, will continue to render every useful truth of practical benefit during life.
