In our schools it is illustrated by the treatment of geography, grammar, and history. In beginning the study of geography in the third or fourth grade it has been customary to outline the whole science in the first primary book. The earth as a whole and its daily and yearly motion, the chief continents and oceans, the general geographical notions, mountain, lake, river, etc., are briefly treated by definition and illustration. Having completed this general framework of geographical knowledge during the first year, the second year, or at least the second book, takes up the same round of topics again and enters into a somewhat fuller treatment of continents, countries, states, and political divisions. The last two years of the common school may be spent upon a large, complete geography; which, with larger, fuller maps and more names, gives also a more detailed account of cities, products, climate, political divisions, and commerce. Finally, physical geography is permitted to spread over much the same ground from a natural-science standpoint, giving many additional and interesting facts and laws concerning zones, volcanoes, ocean-beds and currents, atmospheric phenomena, geologic history, etc. The same earth, the same lands and oceans, furnish the outline in each case, and we travel over the same ground three or four times successively, each time adding new facts to the original nucleus. There is an old proverb that "repetition is the mother of studies," and here we have a systematic plan for repetition, extending through the school course, with the advantage of new and interesting facts to add to the grist each time it is sent through the mill. It is an attractive plan at first sight, but if we appeal to experience, are we not reminded rather that it was dull repetition of names, boundaries, map questions, location of places, etc., and after all not much detailed knowledge was gained even in the higher grades? Again, is it not contrary to reason to begin with definitions and general notions in the lower grades and end up with the interesting and concrete in the higher?

In language lessons and grammar it has been customary to learn the kinds of sentence and the parts of speech in a simple form in the third and fourth grades and in each succeeding year to review these topics, gradually enlarging and expanding the definitions, inflections, and constructions into a fuller etymology and syntax. In United States history we are beginning to adopt a similar plan of repetitions, and the frequent reviews in arithmetic are designed to make good the lack of thoroughness and mastery which should characterize each successive grade of work. The course of religious instruction given in European schools is based upon the same reiteration year by year of essential religious ideas. The whole plan, as illustrated by different studies, is based upon a successive enlargement of a subject in concentric circles with the implied constant repetition and strengthening of leading ideas. A framework of important notions in each branch is kept before the mind year after year, repeated, explained, enlarged, with faith in a constantly increasing depth of meaning. There is no doubt that under good teaching the principle of the concentric circles produces some excellent fruits, a mastery of the subject, and a concentration of ideas within the limits of a single study.

The disciples of Herbart, while admitting the merits of the concentric circles, have subjected the plan to a severe criticism. They say it begins with general and abstract notions and puts off the interesting details to the later years, while any correct method with children will take the interesting particulars first, will collect abundant concrete materials, and by a gradual process of comparison and induction reach the general principles and concepts at the close. It inevitably leads to a dull and mechanical repetition instead of cultivating an interesting comparison of new and old and a thoughtful retrospect. It is a clumsy and distorted application of the principle of apperception, of going from the known to the unknown. Instead of marching forward into new fields of knowledge with a proper basis of supplies in conquered fields, it gleans again and again in fields already harvested. For this reason it destroys a proper interest by hashing up the same old ideas year after year. Finally the concentric circles are not even designed to bring the different school studies into relation to each other. At best they contribute to a more thorough mastery of each study. They leave the separate branches of the course isolated and unconnected, an aggregation of unrelated thought complexes. True concentration should leave them an organic whole of intimate knowledge-relations, conducing to strength and unity of character.

There is a growing conviction among teachers that we need a closer articulation of studies with one another. The expansion of the school course over new fields of knowledge and the multiplication of studies already discussed compels us to seek for a simplification of the course. A hundred years ago, yes, even fifty years ago, it was thought that the extension of our territory and government to the present limits would be impossible. It was plainly stated that one government could never hold together people so widely separated. Mr. Fiske says: (The Critical Period of Am. Hist., p. 60) "Even with all other conditions favorable, it is doubtful if the American Union could have been preserved to the present time without the railroad. Railroads and telegraphs have made our vast country, both for political and for social purposes, more snug and compact than little Switzerland was in the middle ages or New England a century ago." The analogy between the realm of government and of knowledge is not at all complete but it suggests at least the change which is imperatively called for in education. In education as well as in commerce there must be trunk lines of thought which bring the will as monarch of the mind into close communication with all the resources of knowledge and experience. Indeed in the mind of a child or of an adult there is much stronger necessity for centralization than in the government and commerce of a country. The will should be an undisputed monarch of the whole mental life. It is the one center where all lines of communication meet. London is not so perfect a center for the commerce and finance of England as is the conscious ego (smaller than a needle's point) for all its forms of experience.

Besides the central trunk lines of knowledge in history and natural science there are branches of study which are tributary to them, which serve also as connecting chains between more important subjects. Reading, for instance, is largely a relative study. Not only is the art of reading merely a preparation for a better appreciation of history, geography, arithmetic, etc., but even the subject-matter of reading lessons is now made largely tributary to other studies. The supplementary readers consist exclusively of interesting matter bearing upon geography, history, and natural science. It is a fact that reading is becoming more and more a relative study, and selections are regularly made to bear on other school work. Geography especially serves to establish a network of connections between other kinds of knowledge. It is a very important supplement to history. In fact history cannot dispense with its help. Geography lessons are full of natural science, as with plants, animals, rocks, climate, inventions, machines, and races. Indeed there are few if any school studies which should not be brought into close and important relations to geography. Again the more important historical and scientific branches not only receive valuable aid from the tributary studies but they abundantly supply such aid in return. Language lessons should receive all their subject-matter from history and natural science. While the language lessons are working up such rich and interesting materials for purposes of oral and written language, the more important branches are also illustrated and enriched by the new historical and scientific subjects thus incidentally treated.

An examination of these mutual relations and courtesies between studies may discover to us the fact that we are now unconsciously or thoughtlessly duplicating the work of education to a surprising extent. For example, by isolating language lessons and cutting them off from communication with history, geography, and natural science, we make a double or triple series of lessons necessary where a single series would answer the purpose. Moreover, by excluding an interesting subject-matter derived from other studies, the interest and mental life awakened by language lessons are reduced to a minimum. Interest is not only awakened by well selected matter taken from other branches but the relationships themselves between studies, whether of cause and effect as between history and geography, or of resemblance as between the classifications in botany and grammar—the relations themselves are matters of unusual interest to children.

Many teachers have begun to realize in some degree the value of these relations, their effect in enlivening studies, and the better articulation of all kinds of knowledge in the mind. But as yet all attempts among us to properly relate studies are but weak and ineffective approaches toward the solution of the great problem of concentration. The links that now bind studies together in our work are largely accidental and no great stress has been laid upon their value, but if concentration is grappled with in earnest it involves relations at every step. Not only are the principal and tributary branches of knowledge brought into proper conjunction, but there is constant forethought and afterthought to bring each new topic into the company of its kindred, near and remote. The mastery of any topic or subject is not clear and satisfactory till the grappling hooks that bind it to the other kinds of knowledge are securely fastened.

Concentration on a large scale and with consistent thoroughness has been attempted in recent years by the scholars and teachers of the Herbart school. It is based upon moral character as the highest aim, and upon a correlation of studies which attributes a high moral value to historical knowledge and consequently places a series of historical materials in the center of the school course. The ability of the school to affect moral character is not limited to the personal influence of the teacher and to the discipline and daily conduct of the children; but instruction itself, by illustrating and implanting moral ideas, and by closely relating all other kinds of knowledge to the historical series, can powerfully affect moral tendency and strength. If historical matter of the most interesting and valuable kind be selected for the central series, and the natural sciences and formal studies be closely associated with it, there will be harmony and union between the culture elements of the school course.

THE CULTURE EPOCHS.

The problem that confronts us at the outset, when preparing a plan of concentration, is how to select the best historical (moral educative) materials, which are to serve as the central series of the course. The culture epochs (cultur-historische Stufen) are, according to the Herbartians, the key to the situation. (This subject was briefly discussed under Interest.)
