The pass led to another, the finest we have seen, and the only part approaching to the sublime we have beheld in Fezzan. It is rugged and narrow; its sides high, and overhanging in some places. The whole exposed rock is a slaty sandstone, with thin strata of alum slate. The path has several trunks of petrified trees, with branches going out from them; the stem very similar to the acacia. They appear as if precipitated from the top. Near the end of the pass, the Wadey Ghrurby opens, with groves of date palms, and high sand hills. The change is sudden and striking; and instead of taking away, added to the effect of the pass we were descending. The hills from the wadey have rugged, irregular, peaked tops, as if produced by some powerful cause; although it appeared, on examination, that all was produced by the mouldering away of the lower strata. The hills are composed of thick beds of blue clay, alternating with sandstone, beds of alum slate, and thick strata of porphyritic clay stone, and all the tops of finely stratified sandstone. Wednesday, June 12. Moved up the valley for about four miles, and halted at a small town, Kharaik, having passed two in our course. Valley, fine groves of palm trees, with cultivated patches; water good, depth of the wells as about Mourzuk; hills bound the valley on the south side, and sand hills on the north. The number of date trees in the eastern and western division of the valley is said to be 340,000. The first division, or Wadey Shirgi, extends from near Seba to within a few miles of Thirtiba; the other, from the termination of Shirgi to Aubari. In the evening saw some of the preparatory steps for a marriage. The woman belonged to this, and the man to the next town. A band of musicians, accompanied by all the women of the village, dancing and singing, with every now and then a volley of musketry. One woman carried a basket on her head, for the purpose of collecting gomah, to form a feast and pay the musicians. They came from the village of the bridegroom, which was about a mile distant. The marriage was not to take place till the feast after Rhamadan. There are very few plants here. A species of asclepias, with milky juice; the agoul, apparently a species of ulex, has a fine red papilionaceous flower; species, with small obovate leaves, pod small and obtuse at the apex. A species of sweet-smelling rue, and two other plants in fruit, one like a veronica, and the other I have not seen a similar one before.
