第10章 CHAPTER II.(2)

There was no object to attract particular attention, and no sound but that of the bleating goats driven homeward by the Arab boys, and the sharp cry of the desert sand grouse as they arrived in flocks to drink in the welcome river. The flight of these birds is extremely rapid, and is more like that of the pigeon than the grouse; they inhabit the desert, but they travel great distances both night and morning to water, as they invariably drink twice a day. As they approach the river they utter the cry "Chuckow, chuckow," in a loud clear note, and immediately after drinking they return upon their long flight to the desert. There are several varieties of the sand grouse. I have met with three, but they are dry, tough, and worthless as game.

We slept in the desert about five miles from Berber, and on the following day, after a scorching march of about twenty miles, we arrived at the junction of the Atbara river with the Nile.

Throughout the route the barren sand stretched to the horizon on the left, while on the right, within a mile of the Nile, the soil was sufficiently rich to support a certain amount of vegetation--chiefly dwarf mimosas and the Asclepias gigantea. The latter I had frequently seen in Ceylon, where it is used medicinally by the native doctors; but here it was ignored, except for the produce of a beautiful silky down which is used for stuffing cushions and pillows. This vegetable silk is contained in a soft pod or bladder about the size of an orange.

Both the leaves and the stem of this plant emit a highly poisonous milk, that exudes from the bark when cut or bruised;the least drop of this will cause total blindness, if in contact with the eye. I have seen several instances of acute ophthalmia that have terminated in loss of sight from the accidental rubbing of the eye with the hand when engaged in cutting firewood from the asclepias. The wood is extremely light, and is frequently tied into fagots and used by the Arabs as a support while swimming, in lieu of cork. Although the poisonous qualities of the plant cause it to be shunned by all other animals, it is nevertheless greedily devoured by goats, who eat it unharmed.

It was about two hours after sunset when we arrived at the steep bank of the Atbara river. Pushing through the fringe of young dome palms that formed a thick covert upon the margin, we cautiously descended the bank for about twenty-five feet, as the bright glare of the river's bed deceived me by the resemblance to water. We found a broad surface of white sand, which at that season formed the dry bed of the river. Crossing this arid bottom of about 400 yards in width, we unsaddled on the opposite side, by a bed of water melons planted near a small pool of water. Afew of these we chopped in pieces for our tired donkeys, and we shared in the cool and welcome luxury ourselves that was most refreshing after the fatigue of the day's journey. Long before our camels arrived, we had drunk our coffee and were sound asleep upon the sandy bed of the Atbara.

At daybreak on the following morning, while the camels were being loaded, I strolled to a small pool in the sand, tempted by a couple of wild geese; these were sufficiently unsophisticated as to allow me to approach within shot, and I bagged them both, and secured our breakfast; they were the common Egyptian geese, which are not very delicate eating. The donkeys being saddled, we at once started with our attendant, Hadji Achmet, at about five miles per hour, in advance of our slower caravan. The route was upon the river's margin, due east, through a sandy copse of thorny mimosas which fringed the river's course for about a quarter of a mile on either side; beyond this all was desert.

The Atbara had a curious appearance; in no part was it less than 400 yards in width, while in many places this breadth was much exceeded. The banks were from twenty-five to thirty feet deep:

these had evidently been over-flowed during floods, bnt at the present time the river was dead; not only partially dry, but so glaring was the sandy bed, that the reflection of the sun was almost unbearable.

Great numbers of the dome palm (Hyphoene Thebaica, Mart.) grew upon the banks; these trees are of great service to the Arab tribes, who at this season of drought forsake the deserts and flock upon the margin of the Atbara. The leaves of the dome supply them with excellent material for mats and ropes, while the fruit is used both for man and beast. The dome palm resembles the palmyra in the form and texture of its fan-shaped leaves, but there is a distinguishing peculiarity in the growth: instead of the straight single stem of the palmyra, the dome palm spreads into branches, each of which invariably represents the letter Y.

The fruit grows in dense clusters, numbering several hundred, of the size of a small orange, but of an irregular oval shape; these are of a rich brown colour, and bear a natural polish as though varnished. So hard is the fruit and uninviting to the teeth, that a deal board would be equally practicable for mastication; the Arabs pound them between stones, by which rough process they detach the edible portion in the form of a resinous powder. The rind of the nut which produces this powder is about a quarter of an inch thick; this coating covers a strong shell which contains a nut of vegetable ivory, a little larger than a full-sized walnut. When the resinous powder is detached, it is either eaten raw, or it is boiled into a delicious porridge, with milk; this has a strong flavour of gingerbread.
