What the reason was for this sudden change of proceeding I cannot say; but all our arguments, of course, were faulty, as we were unable to give them sufficient weight by good presents. That the tidings of the carrying off of three herds of cattle from a village at a few miles’ distance from Yó, by the Tawárek, which arrived this evening, could have had any influence upon this course of policy was rather improbable. [Sidenote: Wednesday, October 15th.] I was so happy as to collect a good deal of information about the country of Shitáti, which we had now entered, once densely inhabited in large and populous cities, and passed the day quietly and usefully. We heard, to our great joy, that we were to go on the next day with the whole expedition. [Sidenote: Thursday, October 16th.] We had scarcely left the place of our encampment when we fell in with an elephants’ track, apparently leading to the well, and followed it for a long distance; it was well trodden, and was an undoubted proof that these huge animals abounded in this wild deserted region, where man had left scarcely any trace of his presence. Having proceeded at a swift rate, we crossed, at the distance of about six miles, a very fine hollow or vale stretching south and north, and capable of producing everything, and even at that time exhibiting a few vestiges of human activity and industry in a small field of wheat, irrigated from those wells called “kháttatír” by the Arabs, which name is given by them also to the spot irrigated in this way. Its native name, if I am not mistaken, is “Yakállogo.” We then came to another hollow, formed like an ancient circus, and having its soil richly impregnated with natron; it is called Bérendé. After a short halt here, we continued our march; and Overweg and I, while our men and camels followed the direct road, turned off towards the south, and visited another hollow, called “Bóro,” in whose deep bottom a lake is formed, which, according to the season and to the quantity of water it contains, like several other water-basins round the lake, may be termed a fresh or brackish-water lake.
