Led on by such discrepancies, perhaps, he will want next to set his world of man in movement. He will thereupon perceive a circulation, so to speak, amongst the various peoples, suggestive of interrelations of a new type. Now so long as he is dealing in descriptions of a detached kind, concerning not merely the physical environment, but likewise the social adjustments more immediately corresponding thereto, he will be working at the geographical level. Directly it comes, however, to a generalized description or historical explanation, as when he seeks to show that here rather than there a civilization is likely to arise, geographical considerations proper will not suffice. Distribution is merely one aspect of evolution. Yet that it is a very important aspect will now be shown by a hasty survey of the world according to geographical regions.
Let us begin with Europe, so as to proceed gradually from the more known to the less known. Lecky has spoken of "the European epoch of the human mind." What is the geographical and physical theatre of that epoch? We may distinguish—I borrow the suggestion from Professor Myres—three stages in its development. Firstly, there was the river-phase; next, the Mediterranean phase; lastly, the present-day Atlantic phase. Thus, to begin with, the valleys of the Nile and Euphrates were each the home of civilizations both magnificent and enduring. They did not spring up spontaneously, however. If the rivers helped man, man also helped the rivers by inventing systems of irrigation. Next, from Minoan days right on to the end of the Middle Ages, the Mediterranean basin was the focus of all the higher life in the world, if we put out of sight the civilizations of India and China, together with the lesser cultures of Peru and Mexico. I will consider this second phase especially, because it is particularly instructive from the geographical standpoint. Finally, since the time of the discovery of America, the sea-trade, first called into existence as a civilizing agent by Mediterranean conditions, has shifted its base to the Atlantic coast, and especially to that land of natural harbours, the British Isles. We must give up thinking in terms of an Eastern and Western Hemisphere. The true distinction, as applicable to modern times, is between a land-hemisphere, with the Atlantic coast of Europe as its centre, and a sea-hemisphere, roughly coinciding with the Pacific. The Pacific is truly an ocean; but the Atlantic is becoming more of a "herring-pond" every day.
Fixing our eyes, then, on the Mediterranean basin, with its Black Sea extension, it is easy to perceive that we have here a well-defined geographical province, capable of acting as an area of characterization as perhaps no other in the world, once its various peoples had the taste and ingenuity to intermingle freely by way of the sea. The first fact to note is the completeness of the ring-fence that shuts it in. From the Pyrenees right along to Ararat runs the great Alpine fold, like a ridge in a crumpled table-cloth; the Spanish Sierras and the Atlas continue the circle to the south-west; and the rest is desert. Next, the configuration of the coasts makes for intercourse by sea, especially on the northern side with its peninsulas and islands, the remains of a foundered and drowned mountain-country. This same configuration, considered in connection with the flora and fauna that are favoured by the climate, goes far to explain that discontinuity of the political life which encouraged independence whilst it prevented self-sufficiency. The forest-belt, owing to the dry summer, lay towards the snow-line, and below it a scrub-belt, yielding poor hunting, drove men to grow their corn and olives and vines in the least swampy of the lowlands, scattered like mere oases amongst the hills and promontories.
For a long time, then, man along the north coasts must have been oppressed rather than assisted by his environment. It made mass-movements impossible. Great waves of migration from the steppe-land to the northeast, or from the forest-land to the north-west, would thunder on the long mountain barrier, only to trickle across in rivulets and form little pools of humanity here and there. Petty feuds between plain, shore, and mountain, as in ancient Attica, would but accentuate the prevailing division. Contrariwise, on the southern side of the Mediterranean, where there was open, if largely desert, country, there would be room under primitive conditions for a homogeneous race to multiply. It is in North Africa that we must probably place the original hotbed of that Mediterranean race, slight and dark with oval heads and faces, who during the neolithic period colonized the opposite side of the Mediterranean, and threw out a wing along the warm Atlantic coast as far north as Scotland, as well as eastwards to the Upper Danube; whilst by way of south and east they certainly overran Egypt, Arabia, and Somaliland, with probable ramifications still farther in both directions. At last, however, in the eastern Mediterranean was learnt the lesson of the profits attending the sea-going life, and there began the true Mediterranean phase, which is essentially an era of sea-borne commerce. Then was the chance for the northern shore with its peninsular configuration. Carthage on the south shore must be regarded as a bold experiment that did not answer. The moral, then, would seem to be that the Mediterranean basin proved an ideal nursery for seamen; but only as soon as men were brave and clever enough to take to the sea. The geographical factor is at least partly consequence as well as cause.
Now let us proceed farther north into what was for the earlier Mediterranean folk the breeding-ground of barbarous outlanders, forming the chief menace to their circuit of settled civic life. It is necessary to regard northern Europe and northern Asia as forming one geographic province. Asia Minor, together with the Euphrates valley and with Arabia in a lesser degree, belongs to the Mediterranean area. India and China, with the south-eastern corner of Asia that lies between them, form another system that will be considered separately later on.
The Eurasian northland consists naturally, that is to say, where cultivation has not introduced changes, of four belts. First, to the southward, come the mountain ranges passing eastwards into high plateau. Then, north of this line, from the Lower Danube, as far as China, stretches a belt of grassland or steppe-country at a lower level, a belt which during the milder periods of the ice-age and immediately after it must have reached as far as the Atlantic. Then we find, still farther to the north, a forest belt, well developed in the Siberia of to-day. Lastly, on the verge of the Arctic sea stretches the tundra, the frozen soil of which is fertile in little else than the lichen known as reindeer moss, whilst to the west, as, for instance, in our islands, moors and bogs represent this zone of barren lands in a milder form.
The mountain belt is throughout its entire length the home of round-headed peoples, the so-called Alpine race, which is generally supposed to have originally come from the high plateau country of Asia. These round-headed men in western Europe appear where-ever there are hills, throwing out offshoots by way of the highlands of central France into Brittany, and even reaching the British Isles. Here they introduced the use of bronze (an invention possibly acquired by contact with Egyptians in the near East), though without leaving any marked traces of themselves amongst the permanent population. At the other end of Europe they affected Greece by way of a steady though limited infiltration; whilst in Asia Minor they issued forth from their hills as the formidable Hittites, the people, by the way, to whom the Jews are said to owe their characteristic, yet non-Semitic, noses. But are these round-heads all of one race? Professor Ridgeway has put forward a rather paradoxical theory to the effect that, just as the long-faced Boer horse soon evolved in the mountains of Basutoland into a round-headed pony, so it is in a few generations with human mountaineers, irrespective of their breed. This is almost certainly to overrate the effects of environment. At the same time, in the present state of our knowledge, it would be premature either to affirm or deny that in the very long run round-headedness goes with a mountain life.
The grassland next claims our attention. Here is the paradise of the horse, and consequently of the horse-breaker. Hence, therefore, came the charging multitudes of Asiatic marauders who, after many repulses, broke through the Mediterranean cordon, and established themselves as the modern Turks; whilst at the other end of their beat they poured into China, which no great wall could avail to save, and established the Manchu domination. Given the steppe-country and a horse-taming people, we might seek, with the anthropo-geographers of the bolder sort, to deduce the whole way of life, the nomadism, the ample food, including the milk-diet infants need and find so hard to obtain farther south, the communal system, the patriarchal type of authority, the caravan-system that can set the whole horde moving along like a swarm of locusts, and so on. But, as has been already pointed out, the horse had to be tamed first. Palæolithic man in western Europe had horse-meat in abundance. At Solutré, a little north of Lyons, a heap of food-refuse 100 yards long and 10 feet high largely consists of the bones of horses, most of them young and tender. This shows that the old hunters knew how to enjoy the passing hour in their improvident way, like the equally reckless Bushmen, who have left similar Golgothas behind them in South Africa. Yet apparently palæolithic man did not tame the horse. Environment, in fact, can only give the hint; and man may not be ready to take it.
The forest-land of the north affords fair hunting in its way, but it is doubtful if it is fitted to rear a copious brood of men, at any rate so long as stone weapons are alone available wherewith to master the vegetation and effect clearings, whilst burning the brushwood down is precluded by the damp. Where the original home may have been of the so-called Nordic race, the large-limbed fair men of the Teutonic world, remains something of a mystery; though it is now the fashion to place it in the north-east of Europe rather than in Asia, and to suppose it to have been more or less isolated from the rest of the world by formerly existing sheets of water. Where-ever it was, there must have been grassland enough to permit of pastoral habits, modified, perhaps, by some hunting on the one hand, and by some primitive agriculture on the other. The Mediterranean men, coming from North Africa, an excellent country for the horse, may have vied with the Asiatics of the steppes in introducing a varied culture to the north. At any rate, when the Germans of Tacitus emerge into the light of history, they are not mere foresters, but rather woodlanders, men of the glades, with many sides to their life; including an acquaintance with the sea and its ways, surpassing by far that of those early beachcombers whose miserable kitchen-middens are to be found along the coast of Denmark.
Of the tundra it is enough to say that all depends on the reindeer. This animal is the be-all and end-all of Lapp existence. When Nansen, after crossing Greenland, sailed home with his two Lapps, he called their attention to the crowds of people assembled to welcome them at the harbour. "Ah," said the elder and more thoughtful of the pair, "if they were only reindeer!" When domesticated, the reindeer yields milk as well as food, though large numbers are needed to keep the community in comfort. Otherwise hunting and fishing must serve to eke out the larder. Miserable indeed are the tribes or rather remnants of tribes along the Siberian tundra who have no reindeer. On the other hand, if there are plenty of wild reindeer, as amongst the Koryaks and some of the Chukchis, hunting by itself suffices.
