We are now, they say, about twelve days from Aheer, exclusive of the stoppages; twelve days, I mean, of twelve hours a-piece. These long stretches are desperately fatiguing, and trying to the health; but there is no remedy. We must make these weary stages on account of the scarcity of water and herbage for the camels. The Kailouees tie their camels by the lower jaw, and fasten the string to the baggage piled on the back of the preceding animal; and the long line moves on well this way. The Tuaricks fasten their bridles, when they ride their maharees, by a round ring in the nose. We had granite again to-day, and fine beds of felspar, pebbles, and rocks. The geology of this portion of Sahara is very interesting, but no crystals have yet been found. Yesterday and to-day, the wind has been high, moderating greatly the heat. The wind is nearly always south-east. The nights are resplendent. Jupiter and Venus are seen close together in beautiful conjunction. The constellation of the Scorpion rises higher in the south, whilst the Pole-star apparently falls. I read nothing nowadays but a few verses of the Greek Testament, and write these miserable leaves of journal. I must save my strength. I am very weak as it is. We have still got nearly forty days of actual travelling to make before we enter Soudan, but we hope Providence will allow us a little rest at Aheer. _10th._--We moved on late this morning up Wady Aroukeen, one hour and a-half, to a place where we have better feeding for the camels; but it was scarcely worth the trouble of loading and unloading, as the animals could have been led up here to this portion of the wady. Wady Aroukeen is in every respect a desirable place for the resting-place of a caravan. It is full of trees and hasheesh, and lined with lofty precipitous rocks, which afford shelter in winter and in summer, and, as say the Scriptures, give "the shadow of a great rock in a weary land." The well dug by the Tanelkums supplies very palatable water. It lies about an hour and a-half from our encampment. I sent off my Soudanese servant this morning to the Tanelkums, to ask them to wait for us; or at least leave the things behind which I require for our use. Yesterday evening the new moon (second evening) was seen by our people, telling them that the Ramadhan was finished. They saluted the pale crescent horn with some discharges of their guns. To-day is a great feast, but they have not the means of keeping it.
