Part 24

And the oasis is a forest of sumptuous splendour, wherein grow bananas (absent in Gafsa), together with every other kind of fruit and vegetable, but chiefly date-palms, that give the highest and most constant return. They cultivate seventy different varieties. There are half a million trees paying taxes--the common variety sixty centimes, the delicate amber-tinted and translucent deglat twice as much; some trees produce more than fifty francs a year. But they require incessant care; "palms must eat and drink," say the Arabs; they drink, in the summer months, a hundred cubic metres of water apiece!

The export of these dates has been going on for centuries; in 1068 the geographer Bekri wrote that almost every day a thousand camels, or even more, leave Tozeur loaded with dates, and the trade will become still livelier when they have finished building the railway which is to connect this place with the present terminus Metlaoui. Maybe the Egyptians introduced the tree into these regions: they cultivated dates as early as 3000 B.C. It is perhaps the earliest fruit of which we have clear record, save that old apple of 4004 B.C. which gave some trouble to Adam and Eve.

In olden days they sold negro slaves here for two or three quintals of dates apiece.

The irrigation of these palms is a hair-splitting business. Water-conduits, varying in size from a brook to the merest runlet, cross and recross each other on palm-stem aqueducts at different levels; the properties are served with the precious element according to time. And inasmuch as the labourers have no clocks or watches, they have devised a complicated and apparently frivolous system of marking the hours; the water is cut off from a certain property, for instance, when a certain shadow shall have attained the length of three footsteps of a man, and so forth; the shadow varies according to the seasons, but, in the long run, everybody is satisfied. There is peace now under the palms; the days are over when the lean and hungry desert folk, who cannot climb trees, used to ride hither and, pointing their guns at the terrified cultivators, make them clamber aloft and throw down a month's provision of dates.

Arabs will tell you that there are 194 water springs at Tozeur; they are ready to give you the names of every one of them, and several more; these unite to form what might almost be called a river, which is then artificially divided into three rivulets--divided so neatly, says an old writer, that even some fragment of wood or other object drifting down the current is split up, perforce, into three equal parts, one for each of them; these three, later on, are once more subdivided into seven smaller ones apiece--twenty-one in all; and these, again, into a certain fixed number of almost microscopic brooklets. Allah is all-knowing! To me, wandering for the first time in this region, the irrigation canals seemed to flow from every point of the compass. I teased my spirit with the imaginary task of unperplexing the liquid maze, of drawing a map of this dædal network of intersecting waters.

You can stroll in every direction along shady paths in the oasis and never weary of its beauty. The tiller-folk are a happy people--one can see from their faces that they have few cares; those that are not at work under the trees may be seen splashing about the brooks or wending to market with donkeys that almost disappear under immense loads of green stuff; they will greet you with a smile and a "Bon soir, Moussié!" (It is always bon soir.)

Seven little villages nestle under the palms; here and there, too, you enter unexpectedly upon gem-like patches of waterless, shimmering sand--mock-Saharas, golden and topaz-tinted, set in a ring of laughing greenery; there are kingfishers in arrowy flight or poised, like a flame of blue, over the still pools; overhead, among the branches, a ceaseless cooing of turtle-doves. At this season, a Japanese profusion of white blossoms flutters in the breeze and strews the ground; these peaches, apricots, plums and almonds are giants of their kind, and yet insignificant beside the towering trunks of the palms whose leaves shade them from the sunny rays; the fruit trees, in their turn, protect the humble corn and vegetables growing at their feet.

During the Turkish period these oases were in danger of their lives; the sand invaded them, choking up the waters and gradually entombing the plants. The nomads and their flocks and camels, pasturing at liberty round the cultivated tracts, had destroyed the scrub vegetation which hindered the flying desert sands from penetrating into the groves; they had trampled to powder the soil at these spots, so that every breath of wind raised it heavenwards in a cloud. But the peril is averted now by the system of tabias or sand-dykes introduced some twenty years ago--introduced, I believe, in accordance with the suggestion of Monsieur Baraban, whose book on Tunisia drew attention, among other things, to this deplorable condition of the oases and the threatened loss to the exchequer.

Now, if you look closely at this sand, you will see that it is full of minute crystalline particles, and that, in places where it lies undisturbed, these hard and jagged grains wedge themselves into the softer ones and form a coherent crust. It was observed that the wind cannot raise this crust, and the problem how to manufacture it in the neighbourhood of the oases was solved by enclosing the near-lying tracts of half-desert within low mounds crowned by upright palm branches, and forbidding all access to man and beast. The flying plague heaps itself against the palisade and submerges it; a new set of branches is then inserted, and so the structure grows higher and more efficacious every year. The soil within the enclosures, meanwhile, grows hard; wild shrubs sprout up to help in the work, and though the crust yields, like thin ice, at the slightest pressure of the fingers, the end is accomplished.

The protected districts are already assuming a different aspect from the true desert outside, which shifts with the breeze; apart from their tufts of vegetation, the soil has become quite dark in colour. Only the most reckless of nocturnal nomads will dare to violate these hallowed precincts in search of firewood; the citizens have already learned to regard them with reverential fear. At a long distance from the town I asked a small boy to climb over the palisade.

"Not if you give me a packet of cigarettes!" he said. "The brigadier"--in an awed whisper--"he sees everything."

Hearing that protective works of a new kind are being carried on at this moment, I walked yesterday to the bare slopes that lead down to the water-springs. A hundred or more Arabs were engaged, under the supervision of a keen-eyed young Frenchman, in digging a multitude of curved concentric ditches across the hollow of the catchment area, intersected by diagonal ones here and there; the general appearance of the work--the bright yellow of the newly excavated part set against the dark ground of the old--was as if some gigantic fishing-net had been carelessly thrown across the country. These little dykes were about two feet deep, and there must have been already some twenty miles of them. The overseer explained:

"You see what happens. Our putting this tract under the tabia-system had prepared us an unpleasant surprise. The rain formerly used to sink into the soft sand, but since the crust has formed, thanks to our efforts, it no longer sinks, but runs over the hard surface, pours in a flood down that steep incline at whose foot the fountains issue, and threatens to suffocate them with soil torn from its banks. The very life of the oasis was imperilled by our well-meant artifices. But now, with these little ditches, we hope to catch and tame the showers, and force them to wander about in these channels till they either sink into the earth or evaporate. Not a drop of liquid is to leave the catchment basin; it is exactly the reverse of what we desire in Europe."

It struck me as a simple and efficient device.

Midday came and the workers were paid off, each of them receiving a slip of printed paper for the half-day's work; the possession of four of these slips entitles them to exemption from the yearly tax of two francs forty centimes which they would otherwise pay: a good example of the "politique d'association." They trooped away gleefully, and I could not help remarking on their cheerful humour.

"They are gentle as young girls," he said, "and far more tractable; thievish, of course, and untruthful--but so are all children! They attach themselves to me in a pathetic, dog-like fashion, without hope of preferment or any ulterior object.... Yes, they have established themselves in my heart, somehow or other; perhaps because I am an orphan and rather lonely and susceptible.... I really love these poor Arabs, as a father might love them----"

"That stick of yours: it looks business-like. May I ask whether you ever chastise them?"

"Why not? Would I not thrash my own children if they deserved it? This work in Africa," he went on, "attracts and interests me. At home I lose my personality and become a sheep in a herd, but here, in the desert, I can create and leave a mark, which has always been my ambition. I think I could live in this country for ever. Can you understand such a feeling? None of my colleagues can; their minds are in France, and they complain of a colonial exile, as if Tunisia were the Devil's Island; they call me an enthusiast, because I think well of this warm, palpitating soil in which I seem, I don't know how, to have struck deep roots."

And he gazed lovingly over the sea of glossy palm-tops, down yonder, on our right. This, I thought, was a most unusual type of Frenchman; and yet there was something in his language, or perhaps in his ideas, which was already familiar to me.

"To be Sultan of Tozeur, for example--ha! I would bend them to my will; I would lead them to battle and give them laws; I would have them about me as slaves and companions--they should sing to me and tell me stories while I go to sleep. This fair land seems like the realization of some old, dimly remembered dream of mine. How does it all come about, I wonder?"

Sultan of Tozeur--that gave me the cue, and I hazarded the guess that he had inherited his tastes from certain old rovers and conquerors of the northern seaboard.

"True," he said, "our family comes from Normandy, though we have lived in Paris for two generations. Now how on earth did you find that out?"

These are the men whom the Franco-Tunisian administration will do well to encourage as officials and settlers in the wilder parts.

Chapter XXI

OLD TISOUROS

There is a daily recurring spectacle at Tozeur which enchanted me: the camping ground at dawn. Here the caravans repose after their desert journeys; hence they start, at every hour, in picturesque groups and movement. But whoever wishes for a rare impression of Oriental life must go there before sunrise, and wait for the slow-coming dawn. It is all dark at first, but presently a sunny beam flashes through the distant palms, followed by another, and yet another--long shafts of yellow light travelling through the murk; then you begin to perceive that the air is heavy with the smoke of extinguished camp-fires and suspended particles of dust; the ground, heaving, gives birth to dusky shapes; there are weird groans and gurglings of silhouetted apparitions; and still you cannot clearly distinguish earth from air--it is as if one watched the creation of a new world out of Chaos.

But even before the sun has topped the crowns of the palms, the element of mystery is eliminated; the vision resolves itself into a common plain of sand, authentic camels and everyday Arabs moving about their business--another caravan, in short....

And at midday?
