As adults then, in every similar case, are under the necessity of drawing materials from their general knowledge, for the purpose of compounding all such unknown objects, it must be much more difficult for a child to do this, not only because of his want of ability, but his want of materials. The remedy therefore in this case is, to explain and describe the objects that are to be grouped, before the pupil be called upon to do so. And when the object has not been seen by the child, and cannot be exhibited by a picture, or otherwise, the teacher must exert his ingenuity in enabling him to form an idea of the thing that is unknown, by a combination of parts of objects which are. Thus a tiger may be described as resembling a large cat; a wolf, a fox, or even a lion, as resembling certain kinds of dogs; a howdah as a smaller sofa, and a palanquin, as a light crib. In all these cases, it is worthy of notice, that a mere difference of size never creates confusion;—simply because, by a natural law in optics, such differences are of constant occurrence in the experience both of children and adults. A water neut will convey a sufficiently correct idea of a crocodile; and the picture of an elephant, only one inch square, will create no difficulty, if the correct height be given. When these rules have been attended to, it will be found, that this principle in Nature has been successfully imitated; and the pupil, by the previous process of individuation, will be perfectly prepared for the delightful task of grouping the objects which he now knows. When he comes to these objects in the narrative, he conceives the idea of them accurately, and he groups them without effort. There is no hesitation, and no confusion in his ideas. The painting formed upon the mind is correct; the whole picture is united into one connected scene, and is permanently imprinted on the memory for future use.

Another circumstance connected with this principle of grouping in children, we found to be, that when, at any time a greater number of objects were presented to the mind than it was able to reiterate and group, it silently dropt the surplus, and grouped those only which came within the reach of its powers; but if in any instance an attempt was made to force the child to receive and reiterate the ideas of objects beyond a certain point, the mind got confused, and its powers weakened.—The imitation of Nature in this point is also of great importance in education, particularly in teaching and exercising children in reading. To perceive this more clearly, it will be necessary to make a few remarks on the nature of the art of reading.

Reading is nothing more than a mechanical invention, imitative of the act of hearing; as writing is a mechanical mode of indicating sounds, and thus becomes a substitute for the art of speaking, and conveying ideas. But there is this material difference between reading and hearing, that in hearing the person giving attention is in a great measure passive, and may, or may not attend as he pleases. He may receive part of what is said, and, as prompted by Nature, he may silently drop all that he cannot easily reiterate. But in the act of reading, the person has both the active and the passive operations to perform. His mind, while he reads, must be actively engaged in decyphering the words of his book, and the ideas are, or should be, by this act, forced upon the observation of the mind at the same time. As long, therefore, as the child is required to read nothing except that which he understands, and to read no more, and no faster, than his mind can without distraction receive and reiterate the ideas which he reads, the act of grouping will be performed with ease, and with evident delight, and the powers of the mind will be healthfully and extensively exercised and strengthened:—But if this simple principle of Nature be violated, the exercise becomes irritating to the child, and most pernicious in its consequences. The neglect of this application of the principle is so common in education, that it usually escapes observation; but on this very account it demands from us here a more thorough investigation.

We say then, that this principle is violated when a child is required to read that which it does not, and perhaps cannot understand; and also when he is required to read more, or to read faster, than he is able to reiterate the ideas in his own mind. On each of these cases we shall say a few words, for the purpose of warning and directing the teacher in applying this important principle in education.

Let us then suppose a child set to read a section which he does not, and which there is every probability he cannot understand, and then let us carefully mark the consequences. The child in such a case reads the words in his book, which ought to convey to his mind the ideas which the words contain. This is the sole purpose of either hearing or reading. But this is not accomplished. The words are read, and the ideas are not perceived; but the child is required to read on. He does so; and of course when the first part of the subject or sentence has been beyond his reach, the second, which most probably hangs upon it, must be much more so. In this therefore he also fails; but he is still required to read on. Here is a practice begun, which at once defeats the very intention of reading, and allows the child's mind to roam upon any thing or every thing, while the eye is mechanically engaged with his book. The habit is soon formed. The child reads; but his attention is gone. He does not, and at length he cannot, understand by reading. This habit, as we formerly explained, when it is once formed, it requires great efforts on the part of the child to overcome. Most people when they are actively engaged in life, do at last overcome it; while thousands, who have nominally been taught to read, never can surmount the difficulties it involves. Many on this account, and for want of practising an art which they cannot profitably use, lose the art altogether.

But again, let us suppose a child set to read that which he may understand, but which he is required to read more rapidly than allows him to perceive and to reiterate the ideas while reading, and let us mark what are the necessary consequences in such a case. The child is called on to read a sentence, and he does so. He understands it too. But the art of reading is not yet familiar, and he has to bend part of his attention to the decyphering of the words, as well as to the perception and reiteration of the ideas. This requires more time in a child to whom reading is not yet familiar, than to a child more advanced. But give him a little time, and the matter is accomplished the ideas have been received, and they will be reiterated, grouped, and committed to the keeping of the memory,—and then they will form part of his knowledge. But if this time be not given,—if the child, while engaged in collecting the ideas from the words of one sentence, be urged forward to the reading of another, the mental confusion formerly described instantly takes place. More ideas are forced upon the mind than it can reiterate; no group can be formed, because the elements of which it ought to be composed, have not yet been perceived; the imagination gets bewildered;—the mind is unnaturally burdened;—its faculties are overstretched;—the child is discouraged and irritated; the powers of his mind fatigued and weakened; and the whole object of the teacher is at once defeated, and rendered worse than useless.—In every case, therefore, when the child is called on to read, sufficient time should be given;—the teacher taking care that the main design of reading, that of collecting and grouping ideas, be always accomplished; and that the pupil reads no more at one time than he can thoroughly understand and retain.

There is yet another circumstance connected with this process of grouping, which ought not to be overlooked. It refers to the order in which the objects to be grouped by the child are presented to his notice. A child under the guidance of Nature, receives and retains its impressions of objects in a natural and simple order. When it witnesses a scene, the group of objects, or actions formed and pictured on the mind by the imagination, is exactly as they were seen, the one circumstance following the other in natural and regular order. In telling a story therefore to a child, and more especially in composing lessons for them to read, this part of Nature's plan should be carefully studied and acted upon. The elements of which the several groupings are composed, or the circumstances in the narrative to be related, should be presented in the order in which the eye would catch them in Nature, or the order in which they occurred, that there may be no unnecessary retrogression of the mind, no confounding of ideas, no fear of losing the links that connect and bind together the minor groupings of the story. In the history of Cain and Abel, for example, the child is not to be required to paint upon his imagination, a deadly struggle between two persons of whom as yet he knows nothing; and then, retiring backwards in the story, be made acquainted with the circumstances connected with their several offerings to God; and last of all, their parentage, their occupations, and their characters. The minds of the young and inexperienced would be perplexed and bewildered by such a plan of proceeding; and the irregularity would most probably be the cause of their losing the whole story. The opposite of this plan is no doubt frequently adopted in works of fiction prepared for adults, and for the sake of effect; but every one must see that it is unnecessary in simple history, and is not at all adapted for the instruction of the young. When Nature's method is adopted, the child collects and groups the incidents as he proceeds, and paints, without effort, the whole living and moving scene on his imagination, as if he himself had stood by, and been an eye-witness of the original events.

The ascertained benefits of these modes of imitating Nature, are literally innumerable; and it is happily within the power of every parent or teacher, in a single hour, to test them for himself. We shall merely advert to one or two instances which occurred in the recorded experiments, where their effects, in combination with the other principles, were conspicuous.

In the experiment upon the prisoners in the County Jail of Edinburgh, the acquisition of their knowledge of Old Testament History, instead of being a burden, was to them a source of unmingled gratification. There were painted upon their minds the leading incidents in the history of the patriarchs, not only in groups, but their judgments being ripened, they were able to perceive them in regular connection. These pictures, then so pleasantly impressed on their imaginations, are likely to remain with them through the whole of their lives. The Report says, that "they were examined on their knowledge of the Book of Genesis," and "gave a distinct account of its prominent facts from Adam down to the settlement in Goshen, and shewed by their answers that these circumstances were understood by them in their proper nature and bearings."

By the same means, but in less time, and to a greater extent, the same object was attained with the children in Aberdeen, who, though chosen from the schools specially on account of their want of knowledge, were, by only a few hours teaching, enabled, besides many other subjects of knowledge, to receive and retain on their minds the great leading circumstances that occurred from "the death of Moses downwards, to that of the revolt of the ten tribes in the reign of Rehoboam."
