Before 2 P.M. we approached a large _kasbah_ at a place called Douerani. When we afterwards learned that this belonged to the same chief who hospitably received M. Balansa, and assisted him in exploring the neighbourhood until orders from Marocco cut his stay short, we had some doubt whether this was not the place described by him as Keira. An examination of his map and the account of his expedition leads us, however, to the conclusion that Keira must be the name of another habitation belonging to the same chief, lying a few miles farther north, and that the mountain called Djebel Aït Ougurt, ascended by M. Balansa, must be some eminence in the range near at hand which we had just before been scrutinising. We now perceived that there is a considerable valley or depression lying between this outer range and the main mass of the Atlas, which is, indeed, indicated in M. Balansa’s sketch map. Before long we received a courteous message inviting us to stop at the _kasbah_; but as it seemed clear that Seksaoua promised more easy access to the higher mountains, we had no hesitation in adhering to the plan already fixed, and declining the proffered hospitality. It was not without regret that we adhered to our resolution, when the chief came out with a numerous suite to visit us at our halting-place close to the _kasbah_. The friendly air of the worthy old man, which evidently made a deep impression on M. Balansa, was not without effect upon us. Failing to induce us to stop on our way, he sent an ample _mona_, including, besides tea and sugar, a parcel of candles of French manufacture, the more acceptable as our supply threatened to run short before we could reach Mogador. Our halting-place was in a pleasant spot overlooking the broad bed of the Oued Usbi, which appears to unite the torrent from a considerable valley south of Seksaoua with several minor streams from the Atlas, and to be the main affluent of the river of Sheshaoua. The weather had improved, and the thermometer stood at about 70° F. in the shade, our height above the sea being 2,671 feet (814·3 m.). Spiny _Compositæ_ belonging to the genera _Scolymus_, _Echinops_, _Cnicus_, and _Onopordum_, were the most conspicuous plants; but, as no species not already gathered were seen here, we dispensed ourselves from collecting and drying these troublesome inmates of the herbarium.
