Geography has an equally close relation to history stories. For these grades geography and history cover the same geographical regions. Instead of being totally isolated from each other they should be purposely laid out on parallel lines with interlacing topics. North America and the Atlantic ocean are the field of action in both cases. These maritime explorers opened up the geography of this hemisphere at its most interesting stage. No part of the Atlantic ocean or of its North American coasts was overlooked by the navigators. The climate, vegetation and people upon its islands and coasts were curious objects to European adventurers. The first pioneers surveyed the eastern coast and the adjacent interior of a new continent, with its bays, rivers, forests, and mountains. The stories themselves are not intelligible without full geographical explanations, and the personal interest in the narratives throws a peculiar charm upon the geography.

The Mississippi valley is a great field for both history and geography. It is one of the striking physical features of North America and the best of stories find their setting in this environment. Not a great river of this region but is the scene of one of the stories. The lakes and streams were the natural highways of the explorers and settlers. The mountains obstructed their way, presenting obstacles but not limits to their enterprise. The great forests housed their game, concealed their enemies, and had to be cut down to make space for their homes and cornfields. The prairies farther west were a camping ground for them as well as for the deer and buffalo. There are no important physical features of the great valley that are not touched more or less in detail by the stories. It is the work of the geography of this year to enlarge and complete the pictures suggested by the stories, to multiply details, to compare and arrange and to associate with these the facts of our present political and commercial geography.

The relation between history and geography is so intimate that it requires some pedagogical skill to determine which of the two should take the lead. But we have already adjudged the history to be by far the more important of the two. Its subject-matter is of greater intrinsic interest to children, and as it already stands in the commanding center of the school course, we are disposed to bring the geography lessons into close dependence upon it.

In these grades natural science or nature study form a necessary complement to the circle of historical and geographical topics treated. Many interesting natural-science subjects, suggested by history and geography, can not be dealt with satisfactorily in those studies; for example, the tobacco plant, the cactus, the deer, the hot springs, the squirrel, the mariner's compass. Natural science studies begin naturally with the home neighborhood, with its plants, trees, animals, rocks, inventions, and products. But having surveyed and learned many of these things at home in his earlier years, the child is prepared, when geography and history begin, to extend his natural-science information to the larger geographical regions.

The history stories and geography suggest a large number of natural-science topics, so that there is abundant choice of materials while remaining in close connection with those studies. The vegetable and animal life and products of the sea, suggested by the voyages, are fishes, dolphins, whales, sea-birds, shells. Other topics are the construction of ships, the mariner's compass, and astronomy. The stories of the land pioneers open up a still richer field of natural science study for the common schools. Among animals are the beaver, otter, squirrel, coon, bear, fox, wildcat, deer, buffalo, domestic animals, wild turkeys, ducks, pigeons, eagle, hawk, wild bees, cat-fish, sword-fish, turtle, alligator, and many more. Among native products and fruits are mentioned corn, pumpkins, beans, huckleberries, grapes, strawberries, cranberries, tobacco, pawpaw, mulberry, haw, plum, apple, and persimmon. Of trees are oak, hickory, walnut, cypress, pine, birch, beech, and others. Tools, instruments, and inventions are mentioned, with their uses, as guns, Indian weapons, compass, thermometer, barometer, boats, carpenter's tools; also, the uses of iron, lead, leather, and many of the simple arts and economies of life, such as weaving, tempering of metals, tanning, and cooking. The natural wonders of the country, such as falls, caves, hot-springs, canons, salt licks, plains, interior deserts, and salt lakes, kinds of rocks, soils, forests and other vegetation, the phenomena of the weather and differences in climate, are referred to. All these and other topics from the broad realm of nature are suggested, any of which may serve as the starting point for a series of science lessons.

How far the natural science lessons can heed the suggestions of history and geography and still follow out and develop important science principles, is one of the great problems for solution. It would seem that the large number of natural-science topics touched upon by the history, when increased by the variety of home objects in nature and by still others called up by the geography work of these years, would give sufficient variety to the natural science work of the same period. By omitting some of these topics and enlarging upon others, developing the notions of classes and principles so far as is desirable, the natural-science lessons may be made sufficiently scientific without losing the close relation to the central subject-matter for the year. There is no doubt but the science-lessons will add greatly to many topics suggested by the stories and will bring the whole realm of nature into close relation to history and geography.

The subjects thus far discussed, that may be brought into close relation to the central stories, are oral and written language, reading and literature, geography, and the natural sciences. The connection between these branches are numerous and strong at every step. Drawing has a very intimate and important relation to the objects described in history, natural science, arithmetic, and geography; while the songs learned should express in those poetic and rhythmic forms which appeal so strongly to the feelings, many of the noblest ideas suggested by travel, scenery, history, and the experiences of home life.

Arithmetic, finally, seems to stand like an odd sheep among the studies. It is certainly the least social of the common school branches. While avoiding all forced connection between arithmetic and other studies, we shall find some points where the relations are simple and clear. Children in the first grade should see numbers in the leaves, flowers, trees, and animals they study. At the beginning of the first grade this would be a good informal way of beginning numbers. The value of objects in first and second grade number is so great that it is only a question as to how far the objects suggested by other lessons may be used.

But we are speaking of concentration in the fourth and fifth grades. In the stories and in geography we deal with journeys up great rivers, with the height of mountains, with the extent of valleys and lakes, with regular forts, mounds, and enclosures, with companies and bodies of men, with railroads, cities, and agricultural products, and with many other topics which suggest excellent practical problems in arithmetic for these grades. All such careful arithmetical computations add clearness and definiteness to historical and geographical ideas. The natural sciences have been so little systematically taught in our common schools, that we are scarcely able to realize what connection may be made between them and arithmetic. We know that in the advanced study and applications of some of the natural sciences, mathematics is an essential part.

A brief retrospect will make it appear that the history stories, natural sciences, and geography, with the more formal studies, such as reading, language, and arithmetic, may be brought into a close organic harmony. Each of them depends upon and throws light upon the other; and while the connections are natural, not forced, there is a concentration upon the central historical and literary matter that makes moral character the highest aim of teaching.
