Our trip up the Nile to Assouan, or the first cataract, past the silent shapes of the temples, sphinxes and pyramids, surrounded by sights and sounds of Oriental life, was as pastime. But now the holiday journey ends, and we are face to face with the realities and hardships of a Nubian desert. The Nile is no longer verdant on either side. The sands, dry and barren, form its shores. But that is not all. You skirt it to Korosko amid difficulties, and there you are at its great bend. If you followed it now to the next place of importance, Abu-Hammed, you would have to travel nearly 600 miles. The waters are broken by falls and the country is desolate. No one thinks of the journey, unless compelled to make it. The course is that of the caravans across the Korosko desert to Abu-Hammed. It is 400 miles of dreary waste, and calculated to burn out of the traveller any romance he may have entertained of Nubian adventure. Day marching over this desert is impossible at certain seasons. Night is given up to the uneasy motion of camel riding and the monotony of a desert tramp. Do not think the ground is even. Here and there it is broken by wady’s or gulches, and as you descend into these the eye may be relieved with sight of vegetation. Perhaps a gazelle dashes away in fright to the nearest sand hills, or it may be you catch a glimpse of a naked Arab youth tending his flock of goats, for even desert wastes are not utterly void of plant and animal life. These deserts are not even rainless, though as much as four years have been known to pass without a shower. A rain storm is watched with breathless hope by the nomad Arab tribes. They see the clouds drifting up from the distant Indian Ocean and pitching their black tents on the summits of the mountains that divide the Nile Valley from the Red Sea. A north wind may blow during the night and sweep them back whence they came. But more likely they burst into thunderstorm, as if all the storms of a season were compressed into one. The dry wadys of yesterday are roaring torrents by morning, bearing to the Nile their tribute of a single day, and for a day or a week, the desert air is pure and the desert sand shoots a tender vegetation, only to be withered, like Jonah’s gourd, in fewer hours than it sprang. The Arab camel driver, however, knows well a few spots where are running water and green turf the year round. These are the oases, or stepping stones, by means of which the burning wilderness may be crossed. Sometimes the wells fail, or have been poisoned or filled, or are in the possession of a hostile predatory band. Then the unfortunate traveller has to face death by thirst or exhaustion as he hurries on to the next halting place. At any rate he is profoundly thankful when the welcome waters of the Nile come into view again at Abu-Hammed, and he knows he is within safe navigable distance of Kartoum, at the junction of the White and Blue Nile.
