“The crocodile perceives, while it is floating on the surface in mid stream, or from the opposite side of the river, a woman filling her girba,[121] or an animal drinking, etc. Sinking immediately, it swims perhaps a hundred yards nearer, and again appearing for an instant upon the surface, it assures itself of the position of its prey by a stealthy look; once more it sinks, and reaches the exact spot above which the person or animal may be. Seeing distinctly through the water, it generally makes its fatal rush from beneath—sometimes seizing with its jaws, and at other times striking the object into the water with its tail, after which it is seized and carried off. “The crocodile does not attempt to swallow a large prey at once, but generally carries it away, and keeps it for a considerable time in its jaws in some deep hole beneath a rock, or the root of a tree, where it eats it at leisure.”[122] The fish which I had caught were of the same species as those which I had previously landed, and proved very good at table in the evening. It was our custom to dress for dinner—in pyjamas. On March 28 our journey lay through the desert, and reminded us of our first marches towards Gedaref. The river banks with their dome palms were the only landmark. Elsewhere nothing was to be seen but sand, with patches of thinly-growing, very coarse grass or low mimosa scrub here and there, and mirage all around us. Next day we travelled twenty-one miles to Adarama. On the way we passed at a distance a great zareba prepared by Osman Digna. This was protected by double walls, each about twelve feet high. There is an interval of some three feet between the two. They enclose a square space of sandy ground, and the sides have a length of about three hundred yards. The Dervish leader intended to occupy it after the battle of the Atbara. The defences are now slowly falling to pieces; for the walls are made of sun-dried mud, and as this becomes weatherworn and crumbles the wind carries it away, leaving gaps in the ramparts. The sight symbolizes much. Adarama was formerly one of the large towns of the Soudan, but now consists of a few mud huts. There is also a small garrison of about twenty soldiers. The place lies halfway between Gozerajup and Berber, and has a pleasant rest-house among the palm-trees close to the river. The bed of the Atbara is sandy here, and the average breadth is about four hundred yards.
