The death of the two camels having alarmed the conductor of the caravan for the others, we stayed in this place till the middle of the second day after to repose and refresh them previous to entering the desert. During our stay here I engaged a man to swim over to the island opposite, to purchase some durra flour and dates. He could, however, obtain only some dates. I was obliged, in consequence, to reconcile myself to entering the desert short of provisions. I had made provision in Berber for fifteen days, being assured that in twelve days we should have passed the desert, and arrive at the villages on the bank of the Nile four days march above Assuan. The unexpected retardments of our march from Berber had, however, made us nine days in arriving at the place where the road turns into the desert. On the 7th of the moon, at about two hours before sunset, we quitted our halting-place, and after only one hour's march by the border of the river came to a place where the Nile suddenly turns off toward the south-west.[73] At this place the guide told us we were to fill our waterskins, and to quit the river for the desert. We stayed here till the afternoon of the 8th of the moon. The two last nights we have kept watch, and only slept with our hands upon our arms, robbers being, we were told, in this neighborhood, who had lately pillaged some caravans. We were not, however, molested. The desert, on the border of the river hereabouts, abounds with doum trees, which are inhabited by great numbers of monkeys. Its fruit furnishes their food. This fruit consists in a large nut, on the outside covered with a brown substance almost exactly resembling burned gingerbread. It is, however, so hard that no other teeth and jaws, except those of a monkey or an Arab, are well capable of biting it. About one hour's march below our present position is an encampment of Bedouins and the tomb of a Marabout. The people of the country and the caravans had piled his grave with camels' and asses saddles, probably intended as offerings to interest his good offices in the other world.
