_Oct. 22d._--A letter was received this morning from Dr. Barth. It appears that the treaty will not be signed, nor even presented to the Sultan. En-Noor paid me a visit, as usual, this morning. I presented to his highness some old boxes, with which he ordered a door to be made for his palace. His politeness does not cease, and the graciousness with which he receives my presents is really remarkable. The man sent after our camels brought back my poor white maharee, and demanded ten dollars (as good as twenty to me) for his trouble. I refused to give them, preferring to let him have the camel, which is hardly worth ten dollars. This manner of recovering our lost or stolen camels amounts to buying them over again. But it has been our misfortune all along, that our friends, and those who profess to be such, and all who attempt to aid us--every one of them, have profited by our losses, and the disasters which have befallen us. This dispute has been referred to En-Noor, and they have accepted five dollars, which I offered them. I this day made out the statement of the principal items of expenditure which the expedition has incurred from Mourzuk to Tintalous, including the escort to Zinder. It amounts to the enormous sum of three thousand mahboubs, or about six hundred pounds sterling!! If we do not proceed better than this on the future part of the journey, the expedition will at any rate be bankrupt and ruined for want of funds. _23d._--Yusuf and I brought before Overweg this morning the necessity of his assisting in relieving the Government from the double payment of the sums advanced by the Sfaxee. He agreed that it was highly important to save this money, and promised to place his goods at my disposal for sale in Soudan. On the departure of the caravan for Zinder and Kanou every male inhabitant will leave Tintalous, some starting with it and others going for salt, leaving only the women and children behind. This is considered by the Moors as preferable to leaving a few men behind, because these few would occasion quarrels amongst the women, and, besides, excite the jealousy of the absent husbands.
