Dr. Barth arrived early by way of Tintalous. He confirms the news that the Sultans of Aghadez and Asoudee have completely chastised all those tribes who stopped us on the road and levied black mail on us. En-Noor paid us a visit in the morning. After shaking us all in a very friendly manner by the hands, he expressed his regret that he could not go with us now to Zinder. The country was not tranquil, and the people would not consent to his going; but if we wished to proceed immediately with his principal slave, Zangheema, he assured us we should go safely. He then left us to reflect upon what we would do. We decided, without a dissentient voice, that we could not venture to go with Zangheema, and that we must wait for En-Noor, be the time ever so long. We forwarded this decision to his highness, who seemed to receive it with satisfaction. His wife sent us word, "To be sure not to go without her husband;" a piece of advice from a lady we are anxious most religiously to respect. Dr. Overweg made an application, through Daubala and Yusuf, to go to the salt-mines of Bilma with the Kailouees. But either the applicants betrayed the thing, or En-Noor was unwilling to grant permission. Our friend, therefore, is disappointed of this most interesting geological excursion. We are to remove a little further to the west, to a valley more convenient than this for pitching tents, and under some shelter. We still hope we shall not be obliged to await the return of the salt-caravan from Bilma (that is, a month, or forty days) before we start. Probably, when good news comes from the camp in the west we shall go on. It will be a sad trial for our patience to wait so long, after having already dallied more than two months in Tintalous.
