Jan. 22.—A tedious day over sandy deserts, without even the relief of a dark hill to look forward to. About sun-set we came to a spot with some little sprinkling of a grass called _sbeet_, and some fine grass, with a flower called _nisse_. Made twenty-four miles, and halted at Kasama-foma-hamse, or the five trees. No wood nor water. Alarm of Tibboos,—all mounted and turned out. Jan. 23.—Desert as yesterday. High sand hills[20]. Burmenmadua (all sand). At three in the afternoon, we arrived at an extensive wadey, called Aghadem. Here are several wells of excellent water, forage, and numbers of the tree called suag, the red berries of which are nearly as good as cranberries. We broke in on the retreats of about a hundred gazelles, who were enjoying the fertility of the valley. It was, however, with great difficulty, from their extreme shyness, that we shot one, which afforded us an ample meal. A road here branched off to the westward, leading to the Tuarick country, and Soudan, but not frequented by kafilas. Aghadem is a great rendezvous, and the dread of all small kafilas and travellers. It is frequented by freebooters of all descriptions. Jan. 24, we halted. The thermometer, in the shade of my tent, was 101°. at half-past two. The animals were all enjoying the blessings of plenty in the ravines, which ran through the range of low black hills, extending nearly north and south, quite across the valley. The camels, in particular, feasted on the small branches of the suag, of which they are fond to excess. The tracks of the hyæna had been numerous for the last three days; and last night they approached in droves quite close to our encampment. My telescope this evening afforded great delight to Boo-Khaloom, the brother of the kadi at Mourzuk, Mohamed Abeedeen, and several others, for more than an hour. I usually passed some time every evening in Boo-Khaloom’s tent, and had promised them a sight of the moon _grib_ (near), for some time. One old hadje, who obtained a sight by my assistance, for he could not fix the glass on the object, after an exclamation of wonder, looked me fully in the face, spoke not a word, but walked off as fast as he could, repeating words from the Koran. This conduct, I was pleased to see, brought down the ridicule of the others, who were gratified beyond measure, and asked a hundred questions. The night was beautifully serene and clear, and the three splendid constellations of Orion, Canis Major, and Taurus, presented a coup d’œil truly impressive and sublime.
