7th--We made another long and weary day of twelve hours. The fatigue is killing. Our course was south-west, through heaps and groups of rocks and narrow shallow wadys. In some directions, ridges of small rocks; in others, isolated masses of conic form. The bed of the desert is mostly granite, and some of the rocks are of the same substance. Indeed, the Central Sahara seems to bristle with ridges of granite. Then there are many varieties of this stone, and others springing out of granite, as quartz rocks and felspar, and some sandstone mixed with quartz. Across our path we observed many traces of wild oxen, and a few were seen with their immense horns. Birds and reptiles were rare, and the lizard not so frequent as before. Our camels found scarcely a mouthful of hasheesh; no trees were visible, except a few miserable tholukhs. The Kailouees have changed in a marked manner since Wataitee has rejoined us, and are much more civil. But I do not talk to them, contenting myself with a civil "Good day. How do you do?" This prevents them from begging of me. They beg of Barth and Overweg, who do not notice them. As I am "the person who gives," I am obliged to be very polite, but distant. _8th._--We started at sunrise, and made a short day of seven hours and a-half, resting at last in a wady surrounded with rocks, where there was some good herbage. In the course of this march we met another portion of the large Soudan caravan, and consigned to it our letters. They brought the news that the Tanelkums were a day only in advance, having halted to take up water at Aroukeen, where they dug again the old well which had been blocked with stones. This caravan informed us, besides, that the body of the large caravan was resting at the well of Tajetterat. They had seen no Tuaricks. We begin to hope that we have been disturbed by false alarms. At about four hours from the encampment of yesterday we descried some mountains to the south-west. Near them is the well of Janet, said to be about seven hours out of the line of route. It is a frequent resort of Tuaricks, who come to the neighbourhood for hunting purposes. All this region is favourable to sport. Along our route to-day were noticed footmarks of wild oxen and wadan. Wataitee asked me whether he should go to see if there were any Tuaricks at Janet, to get news of them; but I told him that he had better continue with us until we reach Tajetterat. This he has agreed to do; and we all feel that his presence is, to a certain extent, a protection.
