Lesson-time over, the children resort to their tame animals, to their weaving-machines, their wind-mills and dams; to their gardens, kites and ships; to swimming, rowing, foot-ball, marbles, leap-frog, base-ball and cricket. In the practice of these games, skill, dexterity and knowledge are acquired of which the pupils appreciate the utility, and enjoy not only for present, but for anticipated future use.

Natural History, to be taught in school and made a reality, by following the guide given us by nature in the amusements to which children resort of their own accord, should be a prominent subject of instruction and training in the school. Cultivating the faculties of observation and of analysis, it should be among the earliest subjects of instruction, and, at the same time, of amusement.

But they ought not to be taught from books; nature and the teacher are the only books to be employed until considerable progress has been made by the pupils. It is so easy to procure the things themselves for the study of botany; an abundant supply of wild flowers can be so readily obtained, sufficient to enable each child to be supplied with specimens for examination and dissection. The interest of the children in their study can be so easily awakened and sustained by the judicious teacher, the difficulties of the supposed hard words of scientific names disappear so readily, that the real difficulty is to understand how so obvious a subject of instruction is either wholly banished from the schools, or sought to be taught only from books, without any reference to living nature.

The variety and multiplicity of insect life affords ample opportunity for the study of that branch of natural history—and entomology would be found not less beautiful and interesting than botany; the delightful excursions in which teachers and pupils would join for the gathering of objects of natural history would at the same time serve to strengthen the bond of affection which should exist between them. The nature of his own body and the functions of his various organs will soon interest the pupil, and along with instruction therein he would learn the qualities of the different kinds of animal and vegetable substances in use for food, their relative value and importance in building up his body; he would learn to compare the food now in use with that which was employed by our ancestors, and what has given rise to the adoption of the new and abandonment of the old; the methods of cookery best adapted to each kind of food, and what kinds of food are suitable for particular ages and states of health; what material, vegetable or animal, is most suitable for clothing, separately or in combination. He would learn to compare our present style of clothing with that adopted in past ages; he would learn the history of the changes which have been adopted, and while feeling desirous of retaining such as have been wisely adopted, might learn from past experience to desire to return to some good habits as to clothing which have been abandoned.

The tight-fitting garments in which we unhealthily clothe our bodies, a fashion for which we are indebted to the use of armor in times when the chief occupation of man was mutual slaughter, and the great object of desire to secure protection against hostile weapons, might some time come to be discarded for the more healthful practices of the ancient Asiatics and Romans, if a general knowledge of the unhealthfulness of our present practices should come to prevail.

The necessity and meaning of light and cleanliness, the indifference of the human body to all natural changes of temperature, when strengthened and maintained in health by wholesome food and efficient bathing, might lead to the taking of effective measures to restore the old Roman bath to general use.

As regards shelter, why a building on the ground is generally to be preferred to a cave or shelter in the ground—what materials are best adapted for roofs, what for walls, floors, windows, why we use stone or brick in one part of the country and wood in another; what sizes, shapes, means of warmth and ventilation, for privacy and social enjoyment, should be adopted, and as regards furniture and utensils, what are most suitable for the several parts of a dwelling; what should guide our selection of material, fabrics, shape, size and pattern; how to establish a communication from one part of a building to another; how water and light are to be had most readily. All these things should form the subject of school study and inquiry.

The means of locomotion, how streets, roads and paths should be laid out and maintained; the construction and use of carriages, cars, wagons, tramways, railroads, ships, steamers, propelling power; where bridges should be built, and how; viaducts and embankments to cross valleys, cuttings and tunnels to penetrate hills and mountains; these, too, simply at first, and afterwards in more elaborate detail, should form subjects of school instruction, the rules determining the selection of each and the methods of their construction not being preached in lectures, ex Cathedra, but evolved by a patient questioning of nature, by experiment and the Socratic method of inquiry. Exercise of the limbs under the direction of a skilled instructor, so that all the muscles of the body may be duly trained, and a healthy body built up to support a healthy mind. The kinds of recreation to be selected, whether bull-baiting, cock-fighting, rat-catching or prize-fighting, should be preferred to games of skill and strength, to the drama, literature, works of art, public walks, gardens, and museums; the comparative influence of all these upon the health, strength, courage, activity, humanity, refinement and happiness of society; how people may be led to prefer such as tend to general well-being to those which have a tendency to brutalize and debase. All these also should be dwelt upon in the school.

How stores of food, of clothing, of fuel and of the materials for building may be collected and preserved; how present labor may be made to supply future wants, and the thought of future enjoyment be made to sweeten the present toil. How the means of instruction and of amusement may be secured. How all engaged in supplying one need of society co-operate with all who are engaged in supplying its other needs. What form of government is best, and how it may be best administered. How upright judges may be secured, justice administered, and society protected against internal and external foes. These and all the other subjects enumerated would, if handled by a true teacher, be found most attractive to children.

The names given to the subjects at which we have glanced are: Natural History, the Mathematical and Physical Sciences in all their branches, Vegetable and Animal Physiology, the Political and Social Sciences; which should be presented in the order in which the attention and desire to learn could be aroused.
