My eyes to-day were much inflamed by the reflection of the sun's rays from the sand, and at night were very painful and running with matter. Stayed here till about the same hour after midnight as yesterday, when we again set forward. The country the same as yesterday, except that we saw several stony mountains in the desert, some of them at no great distance from the river. Some of these mountains must contain ruins, as at the village where we halted to-day, which we did at about noon, we found a very large and well-fashioned burnt brick, which the peasants said was brought from one of these mountains. The whole of the country through which we have passed for four days contains no cultivable land on this side of the river, except on its margin; but in compensation for this sterility, the islands in this part of the river, which are numerous, very large, and very beautiful, are without a superior for luxuriance of vegetation. Every day when we have come to the river to halt and refresh ourselves, we found one or more in view. At this last station I was lucky enough to purchase a small kid at the enormous price of twelve piasters, the first meat we had eaten for four days. Applied at night a poultice of dates to my eyes, which were much inflamed by today's march, and found some relief from the remedy. At about three hours after midnight we again resumed our travel, and marched till an hour before noon of to-day, the 5th of Zilkade expecting to arrive at the place where the road quits the river, and plunges into the great eastern desert of Africa; but the weather becoming close and very hot, and the camels fatigued, we halted to repose them and ourselves on the bank of the river. Shortly after our arrival two of the camels of the caravan died. Our route still lay through plains and over hills of rock and sand, which come down to the river's edge, but the river, as usual, presented a continual succession of beautiful islands.
