Amongst the plants observed yesterday was the cactus, with a smooth leaf. Water-melons were also found in the road, mostly quite good and sweet, but some white ones perfectly tasteless. None, even those cultivated, are equal to the melons of the coast; there are no mealy ones here. We were met by a party of Tuaricks, who came to salute En-Noor, mounted on horseback. As we had had some very rough customers amongst the Tagama, I took little notice of them, and continued eating my bread and cheese. At this the people of the caravan laughed. They thought we ought always to receive these strangers, Tuaricks, with fear and trembling. I deemed the contrary plan more politic. However, had I known they were official persons, and one son of a sheikh of a town, I should have given them a more civil welcome. _7th._--We came eight hours and a-half south, over an undulating country, intersected with small wadys, and through ghaseb stubble. All was wavy ground, and bare of trees. There is, however, a small hill, at a distance of some ten miles from our encampment, called Boban Birni, "Great City," of conical form. Numerous villages were scattered along the whole line of route, a few of some size. The form of the huts is like that of beehives. Around them are small magazines of ghaseb, supported on wooden stakes, very like corn-stacks. The inhabitants of these Damerghou villages are blacks, with features like the Bornouese. In fact, they speak the Bornou languages, and are said to have been the product of past razzias in that country by the Tuaricks. Damerghou is the granary of Asben, and seems to be entirely in possession of the Asbenouees, nearly all these villages being peopled by the slaves of the Tuaricks. Some villages, indeed, contain nothing but slaves. Few animals were noticed to-day, but we saw four gazelles feeding together, and some hares. Not many birds appeared, on account of the fewness of the trees. Only a small portion of the ground is cultivated, but the camels and cattle are taken to be fed in the waste lands. We encamped at the village of En-Noor, called Tagelel. The capital of Damerghou is on the west (N.W.) from this, and is called Olleloa. The place is governed by Tuaricks. People say there are two or three hundred towns and villages in the country. Damerghou is not considered as part of Soudan, because it is possessed by the Tuaricks; but the country and climate are undoubtedly the same as all the neighbouring Soudanee territories. The weather was very warm and oppressive to-day. I fancied I suffered from the change of climate. I felt not quite well, and was much annoyed by the disobedience of the servants. Mohammed Tunisee has spoiled them all, and even Yusuf has done his share of mischief.
