"There are possibilities," he urges, "in a German protectorate over the Jews as well as over Islam. Smaller national units than the 14 1-3 million Jews have been able to do Germany vital injury or service, and, while the Jews have no national state, their dispersion over the whole world, their high standard of culture, and their peculiar abilities lend them a weight that is worth more in the balance than many larger national masses which occupy a compact area of their own."

Other Powers than Germany may take these possibilities to heart.

Here, then, are peoples risen from the past to do what the Turks cannot and the Germans will not in Western Asia. There is much to be done—reform of justice, to obtain legal release from the Capitulations; reform in the assessment and collection of the agricultural tithes, which have been denounced for a century by every student of Ottoman administration; agrarian reform, to save peasant proprietorship, which in Syria, at any rate, is seriously in danger; genuine development of economic resources; unsectarian and non-nationalistic advancement of education. But the Jews, Syrians, and Armenians are equal to their task, and, with the aid of the foreign nations on whom they can count, they will certainly accomplish it. The future of Palestine, Syria, and Armenia is thus assured; but there are other countries—once as fertile, prosperous, and populous as they—which have lost not only their wealth but their inhabitants under the Ottoman domination. These countries have not the life left in them to reclaim themselves, and must look abroad for reconstruction.

If you cross the Euphrates by the bridge that carries the Bagdad Railway, you enter a vast landscape of steppes as virgin to the eye as any prairie across the Mississippi. Only the tells (mounds) with which it is studded witness to the density of its ancient population—for Northern Mesopotamia was once so populous and full of riches that Rome and the rulers of Iran fought seven centuries for its possession, till the Arabs conquered it from both.

The railway has now reached Nisibin, the Roman frontier fortress heroically defended and ceded in bitterness of heart, and runs past Dara, which the Persians never took. Westward lies Urfa—named Edessa by Alexander's men after their Macedonian city of running waters[49]; later the seat of a Christian Syriac culture whose missionaries were heard in China and Travancore; still famous, under Arab dominion, for its Veronica and 300 churches; and restored for a moment to Christendom as the capital of a Crusader principality, till the Mongols trampled it into oblivion and the Osmanlis made it a name for butchery.

From Urfa to Nisibin there can be fields again. The climate has not changed, and wherever the Bedawi pitches his tents and scratches the ground there is proof of the old fertility. Only anarchy has banished cultivation; for, since the Ottoman pretension was established over the land, it has been the battleground of brigand tribes—Kurds from the hills and Arabs from the desert, skirmishing or herding their flocks, making or breaking alliance, but always robbing any tiller of the land of the fruits of his labour.

"If once," Dr. Rohrbach prophesies, "the peasant population were sure of its life and property, it would joyfully expand, push out into the desert, and bring new land under the plough; in a few years the villages would spring up, not by dozens, but by hundreds."

At present cultivation is confined to the Armenian foot-hills—an uncertain arc of green from Aleppo to Mosul. But the railway strikes boldly into the deserted middle of the land, giving the arc a chord, and when Turco-German strategic interests no longer debar it from being linked up, through Aleppo, with a Syrian port, it will be the really valuable section of the Bagdad system. The railway is the only capital enterprise that Northern Mesopotamia requires, for there is rain sufficient for the crops without artificial irrigation. Reservoirs of population are the need. The Kurds who come for winter pasture may be induced to stay—already they have been settling down in the western districts, and have gained a reputation for industry; the Bedawin, more fickle husbandmen, may settle southward along the Euphrates, and in time there will be a surplus of peasantry from Armenia and Syria. These will add field to field, but unless some stronger stream of immigration is led into the land, it will take many generations to recover its ancient prosperity; for in the ninth century A.D. Northern Mesopotamia paid Harun-al-Rashid as great a revenue as Egypt, and its cotton commanded the market of the world[50].

Southern Mesopotamia—the Irak of the Arabs and Babylonia of the Greeks—lies desolate like the North, but is a contrast to it in every other respect. Its aspect is towards the Persian Gulf, and Rohrbach grudgingly admits[51] that down the Tigris to Basra, and not upstream to Alexandretta, is the natural channel for its trade. It gets nothing from the Mediterranean, neither trade nor rain, and every drop of water for cultivation must be led out of the rivers; but the rivers in their natural state are worse than the drought. Their discharge is extremely variable—about eight times as great in April as in October; they are always silting up their beds and scooping out others; and when there are no men to interfere they leave half the country a desert and make the other half a swamp. Yet the soil, when justly watered, is one of the richest in the world; for Irak is an immense alluvial delta, more than five hundred miles from end to end, which the Tigris and Euphrates have deposited in what was originally the head of the Persian Gulf. The Arabs call it the Sawâd or Black Land, and it is a striking change from the bare ledges of Arabia and Iran which enclose its flanks, and from the Northern steppe-land which it suddenly replaces—at Samarra, if you are descending the Tigris, and on the Euphrates at Hit. The steppe cannot compare with the Sawâd in fertility, but the Sawâd does not so readily yield up its wealth. To become something better than a wilderness of dust and slime it needs engineering on the grand scale and a mighty population—immense forces working for immense returns. In a strangely different environment it anticipated our modern rhythm of life by four thousand years, and then went back to desolation five centuries before Industrialism (which may repeople it) began.

The Sawâd was first reclaimed by men who had already a mastery of metals, a system of writing, and a mature religion—less civilised men would never have attempted the task. These Sumerians, in the fourth millennium B.C., lived on tells heaped up above flood-level, each tell a city-state with its separate government and gods, for centralisation was the one thing needful to the country which the Sumerians did not achieve. The centralisers were Semites from the Arabian plateau. Sargon of Akkad and Naram Sin ruled the whole Sawâd as early as 2500 B.C.; Hammurabi, in 1900, already ruled it from Babylon; and the capital has never shifted more than sixty miles since then. Babylon on the Euphrates and Bagdad on the Tigris are the alternative points from which the Sawâd can be controlled. Just above them the first irrigation canals branch off from the rivers, and between them the rivers approach within thirty-five miles of each other. It is the point of vantage for government and engineering.
