Mimosas and palms are the characteristic trees of all oases, and are never absent from those which have so many springs or wells that gardens and fields become possible. Here they are restricted, like outposts against the invading sand, to the outer fringe of the desert island, while the interior is adorned with more exacting plants which require more water. Thus around the springs or wells there are often charming gardens in which grow almost all the fruit-bearing plants of North Africa. Here the vine clambers, the orange glows amid its dark foliage, the pomegranate opens its rosy mouth, the banana expands its fan-shaped leaf clusters, the melons straggle among the beds of vegetables, prickly-pears and olives, perhaps even figs, apricots, and almonds, complete the picture of fruitfulness. At a greater distance from the centre lie the fields, bearing at least Kaffir-millet, and, in favourable conditions, wheat, or even rice.

In oases so rich man finds a permanent home, while in those which are poorer he is but a sojourner, or a more or less periodic guest. The village or small township of a large oasis is essentially like that of the nearest cultivated country; like it it has its mosques, its bazaars, its coffee-houses; but the inhabitants are children of a different spirit from that which marks the peasants or townsfolk in the Nile valley or along the coast. Although usually of diverse race among themselves they all exhibit the same customs and habits. The desert has shaped and fashioned them. Their slender build, sharply-cut features, and keen eyes, gleaming from under bushy brows, mark them at once as sons of the desert; but their habits and customs are even more characteristic. They are unexacting and readily contented, energetic and full of resource, hospitable and open-hearted, honourable and loyal, but proud, irritable, and passionate, inclined to robbery and acts of violence, like the Bedouins, though not their equals either in good or evil. A caravan entering their settlement is a welcome sight, but they expect the traveller to pay them toll.

Very different from such oases are those valleys in which a much-desired well is only to be found at times. The Arabian nomads are well pleased if the supply of drinking-water for themselves and their herds is sufficient for a few months or even weeks; and the caravan, which rests in such a place, may be content if its demands are satisfied within a few days. The well is usually a deep shaft, from whose walls the water oozes rather than trickles. A few tom-palms rise among the sparse mimosas and saltworts which surround the well; a few stems of grass break through the hard ground.

Unutterably poor are these nomad herdsmen, who pitch their tents here as long as their small flocks of goats can find anything to eat. Their struggle for existence is a continuous succession of toil, and want, and misery. Their tent is of the simplest; a long dark web of cloth, made of goats’ hair, is laid across a simple framework, and its ends pinned to the ground; a piece of the same stuff forms the back-wall, and a mat of palm-leaves forms the door in front. The web is the wife’s self-made dowry, the materials for which she gathered, spun, and wove from her eighth to her sixteenth year. A few mats which serve as beds, a block of granite and a grindstone for pounding the grain got in barter, a flat plate of clay to roast the cakes, two large jars, some leather sacks and skins, an axe and several lances, form the total furnishings. A herd of twenty goats is counted a rich possession for a family. But these people are as brave as they are poor, as lovable as they are well-built, as good-natured as they are beautiful, as generous as they are frugal, as hospitable as they are honourable, as chaste as they are devout. Ancient pictures rise in the mind of the Occidental who meets with these folk for the first time; he sees biblical characters face to face, and hears them speak in a manner with which he has been familiar from his childhood. Thousands of years have been to these nomads of the desert as one day; to-day they think, and speak, and act as did the patriarchs of old. The very greeting which Abraham uttered meets the stranger’s ear; the very words which Rebecca spoke to Abraham’s servant were addressed to me, when, tortured with thirst, I sprang from my camel at the well of Bahiuda, and begged a beautiful brown damsel for a drink of fresh water. There she stood before me, the Rebecca of thousands of years ago, alive and in unfading youth, another and yet the same.

On the arrival of the caravan the whole population of the temporary settlement assembles. The chief steps forward from their midst, and utters the greeting of peace; all the rest bid the strangers welcome. Then they offer the most precious of gifts, fresh water; it is all that they have to give, and it is given with dignified friendliness, ungrudgingly, yet without urgency. Eagerly the travellers drink in long refreshing draughts; the camels also press in riotously upon the watering-place, although they might know from experience that they must first be unloaded, tethered, and turned on the grass before they are allowed to quench an unbroken thirst of four or six days. Even at the well not a drop is wasted, therefore the camels first get any water that remains in the skins, and it is not till these are filled up again that the beasts get a fresh draught, and that with more respect to the existing supplies than their actual needs. Only at the copious wells can one satisfy their apparently unbounded desires, and see, not without amusement, how they swallow without ever looking up, and then hasten from the well to the not less eagerly desired pasture, forced by their hobbles to grotesque and clumsy movements, which make their stomachs rumble like half-filled casks.

And now begins a festival both for travellers and settlers. The former find fresh water, perhaps even milk and meat, to increase the delight of the longed-for resting-time; the latter gladly welcome any break in their life, which, in good seasons, is very monotonous. One of the camel-drivers finds in the nearest tent the favourite instrument of those who live in the desert, the tambura or five-stringed zither, and he knows right well how to use it in accompaniment to his simple song. The music allures the daughters of the camp, and slim, beautiful women and girls press inquisitively around the strangers, fastening their dark eyes on them and their possessions, inquiring curiously about this and that. Steel thy heart, stranger; else these eyes may set it on fire. They are more beautiful than those of the gazelle, the lips beneath put corals to shame, and the dazzling teeth excel any pearls which thou couldst give these daughters of the desert. And soon all yields to music and to song. Around the zither-player groups arrange themselves for the dance; hands both hard and soft beat time to the tune, the words, and the regular swaying movements. New forms come and those we have become familiar with disappear; there is a constantly changing bustle and crowd around the strangers, who are wise if they regard all with the same innocence and simplicity which their hosts display. All the discomforts of the journey are forgotten, and all longings are satisfied, for water flows abundantly and takes the place of all that one might desire in other places or at other seasons.

Such a rest revives body and soul. Strengthened and encouraged the caravan goes on its way, and if the days bring nothing worse than scorching, thirst, and fatigue, a second, and a third well is safely reached, and finally the goal of the journey—the first township on the other side of the desert. But the desert—the sea of sand—is like the all-embracing ocean also in that it is fickle. For here too there are raging storms, which wreck its ships and raise destruction-bringing billows. When the north wind, which blows continuously for months, comes into conflict with currents from the south, or yields them the mastery, the traveller suddenly sees the sand become alive, rising in huge pillars as thick as they are high, which whirl more or less rapidly over the plain. The sun’s rays sometimes lend them the ruddy gleam of flames, at another time they seem almost colourless, yet again, portentously dark, the furious storm weakens them and strengthens them, splits them and unites them, sometimes merging two or more into one huge sand-spout which reaches to the clouds. Well might the Occidental exclaim at the sublimity of the spectacle, did not the anxious looks and words of his escort make him dumb. Woe to the caravan which is overtaken by one of these raging whirlwinds, it will be good fortune if man and beast escape alive. And even if the inexorable messenger of fate pass over the party without doing harm, danger is by no means over, for behind the sand-spouts usually comes the Simoom or poisonous storm.

This ever-dreaded wind, which blows as the Chamasin through Egypt, as the Sirocco towards Italy, as the Föhn through the Alps, as the Tauwind in North Europe, does not always rise into a storm; not unfrequently it is hardly noticeable, and yet it makes many a man’s heart tremble. Of course much that is fabulous is told of it, but this much is true, that it is in certain conditions extremely dangerous to the caravan, and that it is responsible for the bleached skeletons of camels and the half-buried, half-mummified, corpses of men that one sees by the wayside. It is not its strength, but its character, its electric potential, which brings suffering and destruction to man and beast wandering on the sandy sea.

The natives and the observant can foretell the coming of the sand-storm at least one day, often several days, ahead. Unfailing symptoms tell of its approach. The air becomes sultry and oppressive; a light, grayish or reddish vapour obscures the sky; and there is not a breath of wind. All living creatures suffer visibly under the gradually increasing sultriness; men grumble and groan; the wild animals are shyer than usual; the camels become restless and cross, jostling one another, jibbing stubbornly, even lying down on the ground. The sun sets without any colour; no red-glow fringes the evening sky; every light is veiled in a vaporous shroud. Night brings neither coolness nor refreshment, rather an aggravation of the sultriness, the lassitude, the discomfort; in spite of all weariness one cannot sleep. If men and beasts are still able to move, no rest is taken, but they hurry on with the most anxious haste as long as the leader can see any of the heavenly bodies. But the vapour becomes a dry fog, obscuring one constellation after another, hiding moon and sun, though in the most favourable conditions these may be visible, about half their normal size, pale in colour and of ill-defined contour.

Sometimes it is at midnight that the wind begins to raise its wings; more commonly about noon. Without a watch no one could tell the time, for the fog has become so thick that the sun is completely hidden. A gloomy twilight covers the desert, and everything even within a short radius is hazy and indistinct. Gently, hardly perceptibly the air at length begins to move. It is not a breeze, but the merest breath. But this breath scorches, pierces like an icy wind into bone and marrow, producing dull headache, enervation, and uneasiness. The first breath is followed by a more perceptible gust, equally piercing and deadening. Several brief blasts rage howling across the plain.

It is now high time to encamp. Even the camels know this, for no whip will make them take another step. Panic-stricken they sink down, stretch out their long necks in front of them, press them closely on the sand, and shut their eyes. Their drivers unload them as rapidly as possible, build the baggage into a barricade, and heap all the water-bags closely together, so as to present the least possible surface to the wind, and cover them with any available mats. This accomplished, they wrap themselves as closely as may be in their robes, moisten the part which surrounds the head, and take refuge behind the baggage. All this is done with the utmost despatch, for the sand-storm never leaves one long to wait.

Following one another in more rapid succession, the blasts soon become continuous, and the storm rages. The wind roars and rumbles, pipes and howls in the firmament; the sand rushes and rages along the ground; there is creaking and crackling and crashing among the baggage as the planks of the boxes burst. The prevailing sultriness increases till the limit of endurance seems all but reached; all moisture leaves the sweat-covered body; the mucous membranes begin to crack and bleed; the parched tongue lies like a piece of lead in the mouth; the pulse quickens, the heart throbs convulsively; the skin begins to peel, and into the lacerations the raging storm bears fine sand, producing new tortures. The sons of the desert pray and groan, the stranger murmurs and complains.

The severest raging of the sand-storm does not usually last long, it may be only for an hour, or for two or three, just like the analogous thunder-storm in the north. As it assuages the dust sinks, the air clears, perhaps a counter-breeze sets in from the north; the caravan rearranges itself and goes on its way. But if the Simoom last for half a day or for a whole day, then it may fare with the traveller as it did with an acquaintance of mine, the French traveller Thibaut, as he journeyed through the Northern Bahiuda desert. He found the last well dry, and with almost exhausted water-bags he was forced to push on towards the Nile, four days’ journey off. On him and his panic-stricken caravan, which had left every dispensable piece of baggage at the dry well, the deadly storm broke loose. The unfortunate company encamped, hoped for the end of the storm, but waited in vain, mourning, desponding, desperate. One of Thibaut’s servants sprang up maddened, howled down the storm, raged, and raved, and at last, utterly spent, fell prostrate on his master, gasped, and died. A second fell victim to sunstroke, and when the storm at last abated was found dead in his resting-place. A third lingered behind the rest after they had started again on their life-or-death race, and he also perished. Half of the camels were lost. With the remnant of his company Thibaut reached the Nile, but in two days his coal-black hair had become white as snow.

To such storms are due the mummied corpses which one sees by the path of the caravan. The storm which killed them also buries them in the drifting sand; this removes all moisture so quickly that the body, instead of decaying, dries up into a mummy. Over them one wind casts a shroud of sand, which another strips away. Then the corpse is seen stretching its hand, its foot, or its face towards the traveller, and one of the drivers answers the petition of the dead, covers him again with sand, and goes on his way, saying, “Sleep, servant of God, sleep in peace.”

To such storms are also due the dream-pictures of the Fata Morgana which arise in the minds of the survivors. As long as a man pursues his way with full, undiminished strength and with sound senses, the mirage appears to him merely as a remarkable natural phenomenon, and in no wise as Fata Morgana. During the hot season, especially about noon, but from nine in the morning until three o’clock, the “devil’s sea” is to be seen daily in the desert. A gray surface like a lake, or more accurately like a flooded district, is formed on every plantless flat at a certain distance in front of or around the traveller; it heaves and swells, glitters and shimmers, leaves all actually existing objects visible, but raises them apparently to the level of its uppermost stratum and reflects them down again. Camels or horses disappearing in the distance appear, like the angels in pictures, as if floating on clouds, and if one can distinguish their movements, it seems as if they were about to set down each limb on a cushion of vapour. The distance which limits the phenomenon remains always the same, as long as the observer does not change his angle of vision; and thus it varies for the rider and the pedestrian. The whole phenomenon depends on the well-known law, that a ray of light passing through a medium which is not homogeneous is refracted, and thus it is inevitable, since the lower strata of air become expanded by reflection of heat from the glowing sand. No Arab hides his face when he sees a mirage, as fanciful travellers assure their credulous readers; none puts any deep interpretation on the phrase which he likes to use—“the devil’s sea”. But when the anxiety, distress, enervation, and misery consequent on a sand-storm beset and weaken him, and the mirage appears, then it may become a Fata Morgana, for the abnormally excited imagination forms pictures which are in most perfect harmony with the most urgent desire of the moment—the desire for water and for rest. Even to me, who have observed the mirage hundreds of times, the Fata Morgana appeared once. It was after four-and-twenty hours of torturing thirst that I saw the devil’s sea sparkling and gleaming before me. I really thought I saw the sacred Nile and boats with full-bellied sails, palm-groves and woods, and country-houses. But where my abnormal senses perceived a flourishing palm-grove, my equally abnormal comrade saw sailing-boats, and where I fancied I recognized gardens, he saw not less imaginary woodland. And all the deceptive phantasms vanished as soon as we were refreshed with an unexpected draught of water; only the nebulous gray sea remained in sight.

Perhaps every one who crosses a stretch of desert in the Nile-lands sees the devil’s sea; but there is a real and most living desert picture, a sight of which is not granted to all. On the extreme limit of vision, raised perhaps by the mirage and veiled in vapour, a number of riders appear; they are mounted on steeds swift as the wind, with limbs like those of deer; they approach rapidly, and urging to full gallop the steeds which till then they had restrained, they rush down upon the caravan. It always gave me pleasure to meet these haggard, picturesquely-clad men; they and their horses seemed to be so thoroughly harmonious with the desert. The Bedouin is indeed the true son of the desert, and his steed is his counterpart. He is stern and terrible as the desert day, gentle and friendly as the desert night. True to his pledged word, unswerving in obedience to the laws and customs of his race, dignified in bearing, lofty in discourse, unsurpassed in self-restraint and endurance, more sensitive than almost any other man to deeds of prowess, to glory and honour, and not less to the golden web of fancy into which his poetic genius weaves such wondrous pictures and twines such tender fragrant flowers; yet is he cunning and crafty towards his enemies, a bounden slave to his customs, unscrupulous in his demands, mean and paltry in his exactions, greedy in his pleasures, unrestrained in cruelty, terrible in revenge, to-day the noble host, to-morrow a threatening and shameless beggar, now a proud robber and again a pitiable thief. In short he is to the stranger as fickle and changeful as the desert itself. His horse has the same keen, fiery, expressive eyes, the same strength and agility in its thin, almost fragile limbs, the same endurance, the same frugality, the same nature as his master, for they grew up together under the same tent, they rest and dwell beneath the same roof. The animal is not the slave but the companion, the friend of its master, the playmate of his children. Proud, spirited, and even savage in the open desert, it is as quiet as a lamb in the tent; it seems altogether inseparable from its master.

In all the deserts which are, in name at least, under the sway of the Khedive of Egypt, the Bedouins no longer fill the rôle which was theirs in earlier times, and still belongs to them in Arabia and in North-west Africa. For between them and the Egyptian government there is a strict treaty which binds them to allow caravans to pass through their haunts unmolested. Thus robberies in the desert are of the rarest occurrence, and an encounter with the Bedouins raises the less apprehension, since these children of the desert are usually the owners of the hired camels. At the same time the true lords of the waste still love to cling to the old customs and to retain a semblance of their dominion, so that it is prudent before setting out on a desert journey to claim safe-conduct from some recognized chief. With this in possession, an encounter took form somewhat as follows.

One of the sunburnt horsemen sprang forward from the troop, and turned to the leader or head of our caravan.

“Peace be with thee, O stranger!”

“And with thee, O chief, be the grace of God, His mercy, and His compassion!”

“Whither journey ye, sirs?”

“To Belled-Aali, O Sheikh.”

“Do ye journey under protection?”

“We journey under the safe-conduct of his Excellency, the Khedive.”

“And no other?”

“Also Sheikh Soliman, Mohammed Cheir Allah, Ibn Sidi Aulad Aali, has granted us protection and peace.”

“Then are ye welcome and blessed.”

“The Giver of all blessings bless thee and thy father, O chief!”

“Have ye need of ought? My men will supply it. In Wadi Ghitere are our tents, and ye are welcome there if ye seek rest. If not, may Allah grant a prosperous journey!”

“He will be with us, for He is merciful.”

“And the Guide on all good ways.”

“Amen, O chief!”

And the troop wheels off; rider and steed become one; the light hoofs seem scarce to touch the sand, the white burnooses flutter in the wind, and the poet’s words rise into memory—

Such are some of the fascinating pictures shown to the receptive eye. The more intimately one comes to know the desert, the more it grows upon one, alleviating and lessening all toil and discomfort. Yet the last hours of the journey are those of greatest joy. When the first palm-village of cultivated land appears in sight, when the silver line of the sacred river is once more visible, gladness fills the heart. Men and beasts hasten as if to prove that the glad reality is not an illusion which may vanish in the mist. But the goal becomes more and more distinct; it seems as if we had never seen fresher colours, we fancy that nowhere else can there be trees so green, water so cool. With a final effort the camels push on, far too slowly for their impatient riders. Friendly greetings reach our ears. The village on the Nile is reached at last. From all the huts throng men and women, the aged and the children. Inquisitively they crowd around the camp, men and women curiously questioning, youths and maidens eager for the dance. Tambura and tarabuka, the zither and drum of the country, invite to motion; and the dancing-girls gladden the eyes of strangers and countrymen alike. Even the creaking of the water-wheel on the river, formerly a thousand times cursed, seems musical to-day. The evening brings fresh joys. Comfortably couched on the cool and elastic divan, the foreigner pledges the native in palm-wine or merieza—the nectar of the land; while the sound of zither and drum, and the rhythmic hand-clapping of the dancing youths and maidens form a merry accompaniment to the dainty banquet. But at length the approaching night begins to press its claims. Tambura and tarabuka sink into silence and the dance comes to an end; one after another, refreshed and well-content, the travellers seek rest. At length only one is left, a son of Khahira, the mother of the world, whom sleep still refuses to bless. From beside the flickering camp-fire comes his simple, tremulous song—

But this lover’s plaint also dies away, and the silence of the night is unbroken save by the murmurings of the wavelets on the sacred river.
