_20th._--We rested to-day. There is a well a short distance off, called Tilya. This morning early filed by a large division of the salt-caravan, about three hundred camels. We passed them yesterday. They had also a little merchandise besides salt. Some of the people inquired of me if I had found my camels. I told them two were still missing. They were all strangers, but were, nevertheless, civil. I made a short excursion in search of gum amongst the tholukh-trees. I was fortunate enough to find one piece, or, rather, a small bunch of pellucid drops, of a bright amber-colour. The bunch was scarcely exuding from the tree on which it was found, and was ready to drop when touched, hanging by the slenderest connexion. It was even somewhat disposed to become liquid. This gum is found only on the small young trees. The taste was very pleasant. It is astonishing how little gum has been picked off these trees by our people, although we have passed tens of thousands of them _en route_. The slaves of the caravan were having a game amongst themselves this morning. They brought into my tent a man bound as dead, and I was obliged to pay a handkerchief to relieve myself of the bad omen. Such a thing is considered a horrible thing if you do not buy away the ill effects of it. This is certainly an easy way of collecting money and goods. It was, however, amusing to see the fellow, how still he lay; truly it was as still as death. The ceremony itself arose out of the culprit, or man bound, having lost our camels, a circumstance which has detained us here to-day. The herdsman was thus punished for his neglect; and so all these African people have an amusing way of turning their misfortunes into fun, as well as of making a profit out of them. I have already observed before, that every misfortune we have suffered has been a benefit to the Kailouees. This has made them so careless about what might happen to us. _21st._--Our course was generally nearly south, but often a little winding. Baghzem was always on our right, until we left it behind us, on the north-west. This mountain has, probably, been so much celebrated in all past times, because it is the most conspicuous object on the return route from the south to the north. Overweg conjectures that it is granite. He had no servant at hand yesterday to visit it with him, and he did not like to go alone, because it swarms with lions. We passed to-day mostly through undulating country, a sort of ground which, in the Sahara, lies generally between the plateaux and the high rocky ranges. From one of the lesser heights we had a magnificent view of Baghzem. We passed also through and along several fine wadys, lined with ancient trees. Perhaps, in some places, full half of the trees were decayed, and many only naked stumps. The trees were so thick in certain places as to deserve the name of forests--primeval forests--but, I imagine, not to be compared with those of America.
