accumulate population in unhealthy places. The towns were just market towns, as clean and simple as ordinary villages. Therefore the population slowly increased; the scale of living was brought down very low; and a congestion of numbers was generally felt. They could not emigrate overseas; for the Sudan was even worse country than Arabia, and the few tribes which did venture across were compelled to modify their manner of life and their Semitic culture profoundly, in order to exist. They could not move northward along the hills; for these were barred by the holy town of Mecca and its port Jidda: an alien belt, continually reinforced by strangers from India and Java and Bokhara and Africa, very strong in vitality, violently hostile to the Semitic consciousness, and maintained despite economics and geography and climate by the artificial factor of a world-religion. The congestion of Yemen, therefore, becoming extreme, found its only relief in the east, by forcing the weaker aggregations of its border down and down the slopes of the hills along the Widian, the half-waste district of the great water-bearing valleys of Bisha, Dawasir, Ranya and Taraba, which ran out towards the deserts of Nejd. These weaker clans had continually to exchange good springs and fertile palms for poorer springs and scantier palms, till at last they reached an area where a proper agricultural life became impossible. They then began to eke out their precarious husbandry by breeding sheep and camels, and in time came to depend more and more on these herds for their living.
Finally, under a last impulse from the straining population behind them, the border people (now almost wholly pastoral), were flung out of the furthest crazy oasis into the untrodden wilderness as nomads. This process, to be watched to-day with individual families and tribes to whose marches an exact name and date might be put, must have been going on since the first day of full settlement of Yemen. The Widian below Mecca and Taif are crowded with the memories and place-names of half a hundred tribes which have gone from there, and may be found to-day in Nejd, in Jebel Sham-mar, in the Hamad, even on the frontiers of Syria and Mesopotamia. There was the source of migration, the factory of nomads, the springing of the gulf-stream of desert wanderers.
For the people of the desert were as little static as the people of the hills. The economic life of the desert was based on the supply of camels, which were best bred on the rigorous upland pastures with their strong nutritive thorns. By this industry the Bedouins lived; and it in turn moulded their life, apportioned the tribal areas, and kept the clans revolving through their rote of spring, summer and winter pasturages, as the herds cropped the scanty growths of each in turn. The camel markets in Syria, Mesopotamia, and Egypt determined the population which the deserts could support, and regulated strictly their standard of living. So the desert likewise overpeopled itself upon occasion; and then there were heavings and thrustings of the crowded tribes as they elbowed themselves by natural courses towards the light. They might not go south towards the inhospitable sand or sea. They could not turn west; for there the steep hills of Hejaz were thickly lined by mountain peoples taking full advantage of their defensiveness. Sometimes they went towards the central oases of Aridh and Kasim, and, if the tribes looking for new homes were strong and vigorous, might succeed in occupying parts of them. If, however, the desert had not this strength, its peoples were pushed gradually north, up between Medina of the Hejaz and Kasim of Nejd, till they found themselves at the fork of two roads. They could strike eastward, by Wadi Rumh or Jebel Sham-mar, to follow eventually the Batn to Shamiya, where they would become riverine Arabs of the Lower Euphrates; or they could climb, by slow degrees, the ladder of western oases--Henakiya, Kheibar, Teima, Jauf, and the Sirhan--till fate saw them nearing Jebel Druse, in Syria, or watering their herds about Tadmor of the northern desert, on their way to Aleppo or Assyria.
Nor then did the pressure cease: the inexorable trend northward continued. The tribes found themselves driven to the very edge of cultivation in Syria or Mesopotamia. Opportunity and their bellies persuaded them of the advantages of possessing goats, and then of possessing sheep; and lastly they began to sow, if only a little barley for their animals. They were now no longer Bedouin, and began to suffer like the villagers from the ravages of the nomads behind. Insensibly, they made common cause with the peasants already on the soil, and found out that they, too, were peasantry. So we see clans, born in the highlands of Yemen, thrust by stronger clans into the desert, where, unwillingly, they became nomad to keep themselves alive. We see them wandering, every year moving a little further north or a little further east as chance has sent them down one or other of the well-roads of the wilderness, till finally this pressure drives them from the desert again into the sown, with the like unwillingness of their first shrinking experiment in nomad life. This was the circulation which kept vigour in the Semitic body. There were few, if indeed there was a single northern Semite, whose ancestors had not at some dark age passed through the desert. The mark of nomadism, that most deep and biting social discipline, was on each of them in his degree.
Chapter III
If tribesman and townsman in Arabic-speaking Asia were not different races, but just men in different social and economic stages, a family resemblance might be expected in the working of their minds, and so it was only reasonable that common elements should appear in the product of all these peoples. In the very outset, at the first meeting with them, was found a universal clearness or hardness of belief, almost mathematical in its limitation, and repellent in its unsympathetic form. Semites had no half-tones in their register of vision. They were a people of primary colours, or rather of black and white, who saw the world always in contour. They were a dogmatic people, despising doubt, our modern crown of thorns. They did not understand our metaphysical difficulties, our introspective questionings. They knew only truth and untruth, belief and unbelief, without our hesitating retinue of finer shades.
This people was black and white, not only in vision, but by inmost furnishing: black and white not merely in clarity, but in apposition. Their thoughts were at ease only in extremes. They inhabited superlatives by choice. Sometimes inconsistents seemed to possess them at once in joint sway; but they never compromised: they pursued the logic of several incompatible opinions to absurd ends, without perceiving the incongruity. With cool head and tranquil judgement, imperturbably unconscious of the flight, they oscillated from asymptote to asymptote.*
They were a limited, narrow-minded people, whose inert intellects lay fallow in incurious resignation. Their imaginations were vivid, but not creative. There was so little Arab art in Asia that they could almost be said to have had no art, though their classes were liberal patrons, and had encouraged whatever talents in architecture, or ceramics, or other handicraft their neighbours and helots displayed. Nor did they handle great industries: they had no organizations of mind or body. They invented no systems of philosophy, no complex mythologies. They steered their course between the idols of the tribe and of the cave. The least morbid of peoples, they had accepted the gift of life unquestioningly, as axiomatic. To them it was a thing inevitable, entailed on man, a usufruct, beyond control. Suicide was a thing impossible, and death no grief.
They were a people of spasms, of upheavals, of ideas, the race of the individual genius. Their movements were the more shocking by contrast with the quietude of every day, their great men greater by contrast with the humanity of their mob. Their convictions were by instinct, their activities intuitional. Their largest manufacture was of creeds: almost they were monopolists of revealed religions. Three of these efforts had endured among them: two of the three had also borne export (in modified forms) to non-Semitic peoples. Christianity, translated into the diverse spirits of Greek and Latin and Teutonic tongues, had conquered Europe and America. Islam in various transformations was subjecting Africa and parts of Asia. These were Semitic successes. Their failures they kept to themselves. The fringes of their deserts were strewn with broken faiths.
It was significant that this wrack of fallen religions lay about the meeting of the desert and the sown. It pointed to the generation of all these creeds. They were assertions, not arguments; so they required a prophet to set them forth. The Arabs said there had been forty thousand prophets: we had record of at least some hundreds. None of them had been of the wilderness; but their lives were after
