Riehl’s books are not dedicated merely to the argumentative maintenance of this or of any other position; they are intended chiefly as a contribution to that knowledge of the German people on the importance of which he insists. He is less occupied with urging his own conclusions than with impressing on his readers the facts which have led him to those conclusions. In the volume entitled “Land und Leute,” which, though published last, is properly an introduction to the volume entitled “Die Bürgerliche Gesellschaft,” he considers the German people in their physical geographical relations; he compares the natural divisions of the race, as determined by land and climate, and social traditions, with the artificial divisions which are based on diplomacy; and he traces the genesis and influences of what we may call the ecclesiastical geography of Germany—its partition between Catholicism and Protestantism. He shows that the ordinary antithesis of North and South Germany represents no real ethnographical distinction, and that the natural divisions of Germany, founded on its physical geography are threefold—namely, the low plains, the middle mountain region, and the high mountain region, or Lower, Middle, and Upper Germany; and on this primary natural division all the other broad ethnographical distinctions of Germany will be found to rest. The plains of North or Lower Germany include all the seaboard the nation possesses; and this, together with the fact that they are traversed to the depth of 600 miles by navigable rivers, makes them the natural seat of a trading race. Quite different is the geographical character of Middle Germany. While the northern plains are marked off into great divisions, by such rivers as the Lower Rhine, the Weser, and the Oder, running almost in parallel lines, this central region is cut up like a mosaic by the capricious lines of valleys and rivers. Here is the region in which you find those famous roofs from which the rain-water runs toward two different seas, and the mountain-tops from which you may look into eight or ten German states. The abundance of water-power and the presence of extensive coal-mines allow of a very diversified industrial development in Middle Germany. In Upper Germany, or the high mountain region, we find the same symmetry in the lines of the rivers as in the north; almost all the great Alpine streams flow parallel with the Danube. But the majority of these rivers are neither navigable nor available for industrial objects, and instead of serving for communication they shut off one great tract from another. The slow development, the simple peasant life of many districts is here determined by the mountain and the river. In the south-east, however, industrial activity spreads through Bohemia toward Austria, and forms a sort of balance to the industrial districts of the Lower Rhine. Of course, the boundaries of these three regions cannot be very strictly defined; but an
