Contrasted location.

Every land contains in close juxtaposition areas of sharply contrasted cultural, economic and political development, due to the influence of diverse natural locations emphasizing lines of ethnic cleavage made perhaps by some great historical struggle. In mountainous countries the conquered people withdraw to the less accessible heights and leave the fertile valleys to the victorious intruders. The two races are thus held apart, and the difference in their respective modes of life forced upon them by contrasted geographic conditions tends still farther for a time to accentuate their diversity. The contrasted location of the dislodged Alpine race, surviving in all the mountains and highlands of western Europe over against the Teutonic victors settled in the plains,[281] has its parallel in many parts of Asia and Africa; it is almost always coupled with a corresponding contrast in mode of life, which is at least in part geographically determined. In Algeria, the Arab conquerors, who form the larger part of the population, are found in the plains where they live the life of nomads in their tents; the Berbers, who were the original inhabitants, driven back into the fastnesses of the Atlas ranges, form now an industrious, sedentary farmer class, living in stone houses, raising stock, and tilling their fields as if they were market gardeners.[282] In the Andean states of South America, the eastern slopes of the Cordilleras, which are densely forested owing to their position in the course of the trade-winds, harbor wild, nomadic tribes of hunting and fishing Indians who differ in stock and culture from the Inca Indians settled in the drier Andean basins.[283] [See map page 101.]

Geographical polarity.

Every geographical region of strongly marked character possesses a certain polarity, by reason of which it attracts certain racial or economic elements of population, and repels others. The predatory tribes of the desert are constantly reinforced by refugee outlaws from the settled agricultural communities along its borders.[284] The mountains which offer a welcome asylum for the persecuted Waldenses have no lure for the money-making Jew, who is therefore rarely found there. The negroes of the United States are more and more congregating in the Gulf States, making the "Black Belt" blacker. The fertile tidewater plains of ante-bellum Virginia and Maryland had a rich, aristocratic white population of slave-holding planters; the mountain backwoods of the Appalachian ranges, whose conditions of soil and relief were ill adapted for slave cultivation, had attracted a poorer democratic farmer class, who tilled their small holdings by their own labor and consequently entertained little sympathy for the social and economic system of the tidewater country. This is the contrast between mountain and plain which is as old as humanity. It presented problems to the legislation of Solon, and caused West Virginia to split off from the mother State during the Civil War.[285]

Each contrasted district has its own polarity; but with this it attracts not one but many of the disruptive forces which are pent up in every people or state. Certain conditions of climate, soil, and tillable area in the Southern States of the Union made slave labor remunerative, while opposite conditions in the North combined eventually to exclude it thence. Slave labor in the South brought with it in turn a whole train of social and economic consequences, notably the repulsion of foreign white immigration and the development of shiftless or wasteful industrial methods, which further sharpened the contrast between the two sections. The same contrast occurs in Italian territory between Sicily and Lombardy. Here location at the two extremities of the peninsula has involved a striking difference in ethnic infusions in the two districts, different historical careers owing to different vicinal grouping, and dissimilar geographic conditions. These effects operating together and attracting other minor elements of divergence, have conspired to emphasize the already strong contrast between northern and southern Italy.

Geographical marks of growth.

In geographical location can be read the signs of growth or decay. There are racial and national areas whose form is indicative of development, expansion, while others show the symptoms of decline. The growing people seize all the geographic advantages within their reach, whether lying inside their boundaries or beyond. In the latter case, they promptly extend their frontiers to include the object of their desire, as the young United States did in the case of the Mississippi River and the Gulf coast. European peoples, like the Russians in Asia, all strive to reach the sea; and when they have got there, they proceed to embrace as big a strip of coast as possible. Therefore the whole colonization movement of western and central Europe was in the earlier periods restricted to coasts, although not to such an excessive degree as that of the Phoenicians and Greeks. Their own maritime location had instructed them as to the value of seaboards, and at the same time made this form of expansion the simplest and easiest.
