Besides the grand natural feature of innumerable lofty and branching palms, whose dark depending slender leaves, are depicted by the Arabian poet as hanging gracefully like the dishevelled ringlets of a beautiful woman in distress, there is the vast salt lake, El-Sibhah, or literally the "salt plain," and called by some modern geographers the Sibhah-el-Soudeeat, or Lake of Marks, from having certain marks made of the trunks of the palm, to assist the caravans in their marches across its monotonous samelike surface.
This vast lake, or salt plain, was divided by the ancients into three parts, and denominated respectively, Palus Tritonis, Palus Pallas, and Palus Libya. The first is derived from the river Triton, which according to Ptolemy and other ancient geographers, is made to pass through this lake in its course to the sea, but which is the present river Ghobs, where it falls into the Mediterranean. The name Pallas is derived from the tradition of Pallas having accompanied Sesostris in his Asiatic expeditions with the Lybian women, and she may have been a native of the Jereed. The lake measures from north-east to south-west about seventy English miles, with a third of the breadth, but it is not one collection of water; there being several dry places, like so many islands, interspersed over its surface, depending however, as to their number and extent upon the season of the year, and upon the quantity of water in the particular season.
"At first, on crossing it," says a tourist, "the grass and bushes become gradually scarcer; then follows a tract of sand, which some way beyond, becomes in parts covered with a thin layer of salt. This, as you advance, is thicker and more united; then we find it a compact and unbroken mass or sheet, which can, however, be penetrated by a sword, or other sharp instrument, and here it was found to be eleven inches in depth; and finally in the centre, it became so hard, deep, and concentrated, as to baffle all attempts at breaking its surface except with a pickaxe. The horse's shoe, in fact, makes no impression upon its stone-like surface."
The salt of the lake is considerably weaker than that of the sea, and not adapted for preserving provisions, though its flavour is very agreeable; it is not exported, nor made in any way an article of commerce.
The Jereed, from the existence in it of a few antiquities, such as pieces of granite and marble, and occasionally a name or a classic inscription, is proved to have been in the possession of the Romans, and undoubtedly of the Carthaginians before them, who could have had no difficulty in holding this flat and exposed country.
The trade and resources of this country consist principally in dates. The quantity exported to other parts of the Regency, as well as to foreign countries, where their fine quality is well known, is in round numbers on an average from three to four thousand quintals per annum. But in Jereed itself, twenty thousand people live six months of the year entirely on dates.
"A great number of poles," says Sir Grenville Temple, "are arranged across the rooms at the height of eight or nine feet from the ground, and from these are suspended rich and large bunches of dates, which compose the winter store of the inhabitants; and in one corner of the room is one or more large earthern jars about six or seven feet high, also filled with dates pressed close together, and at the bottom of the jar is a cock, from which is drawn the juice in the form of a thick luscious syrup. It is scarcely possible to imagine anything more palatable than this 'sweet of sweets.'"
As we are writing of the country of dates, par excellence, I must needs give some description of the palm, but it will be understood that the information is Tunisian, or collected in Tunis, and may differ in some respects from details collected in other parts of North Africa. The date-palm abounds in the maritime as well as in the inland districts of North Africa. They are usually propagated from shoots of full grown trees, which if transplanted and taken care of, will yield in six or seven years, whilst those raised immediately from the stone require sixteen years to produce fruit.
The date-palm is male and female, or dioecious, and requires communication, otherwise the fruit is dry and insipid. The age of the palm, in its greatest vigour, is about thirty years, according to the Tunisians, after planting, and will continue in vigour for seventy years, bearing anually fifteen or twenty clusters of dates, each of them fifteen or twenty pounds in weight; after this long period, they begin gradually to wither away. But the Saharan Tripolitans will tell you that the date-palm does not attain its age of full vigour till it reaches a hundred years, and then will flourish two or or three centuries before it withers!
The only culture requisite, is to be well watered at the roots once in four or five days, and to have the lower boughs cut off when they begin to droop and wither. Much rain, however, injures the dates, and we know that the countries in which they flourish, are mostly without rain. In many localities in Africa, date-palms can never be watered in the dry season; it is nevertheless observable that generally wherever a palm grows and thrives water may usually be obtained by boring. The sap, or honey of the palm is a delicious and wholesome beverage when drunk quite fresh; but if allowed to remain for some hours, it acquires a sharp taste, something like cider, and becomes very intoxicating. It is called poetically leghma, "tears" of the dates. When a tree is found not to produce much fruit, the head is cut off, and a bowl or cavity scooped out of the summit, in which the rising sap is collected, and this is drunk in its pure state without any other preparation. If the tree be not exhausted by draining, in five or six months it grows afresh; and, at the end of two or three years, may again be cut or tapped. The palm is capable of undergoing this operation five or six times, and it may be easily known how often a tree has been cut by the number of rings of a narrow diameter which are seen towards its summit; but, if the sap is allowed to flow too long, it will perish entirely at the end of a year. This sap, by distillation, produces an agreeable spirit called Arâky or Arâk: from the fruit also the Jews distil a spirit called bokka, or what we should call toddy. It is usual for persons of distinction to entertain their friends upon a marriage, or the birth of a child, with this pure sap, and a tree is usually tapped for the purpose. It would appear that tapping the palm was known to the ancients, for a cornelian intaglio of Roman antiquity, has been found in the Jereed, representing a tree in this state, and the jars in which the juice was placed.
