[6] See the papers read before the Geographical Society, in January and March 1851. It appears to me that Mr. A. Petermann slightly depresses the importance of the part played by Mr. Richardson in this mission. However, this may arise from the fact that the communications on which his paper was founded were all from his German friends. It is not necessary to be grudging of notice to any of the three enterprising gentlemen who undertook this arduous journey; but we must always remember who planned the Mission, and who directed it with consummate prudence as long as life and strength lasted. In Mr. Richardson's MS. an outline is given of Dr. Barth's journey, and I therefore insert it, with corrections and additions, from the papers just alluded to.--ED. This agreeable place prefaces the still more luxuriant scenery of Asadah, where the vegetation is so rich, and the path so shut up by branches, that it is difficult to keep on the camel's back. What a contrast to the naked deserts of Ghât! It was from between the rich foliage of this valley that Dr. Barth obtained his first glimpses of the majestic mountain-chain of Dogem, estimated to attain the height of between four and five thousand feet. It is the loftiest range in Aheer. The plain of Erarer-en-Dendemu, which next succeeds, is covered with brushwood and low trees, and inhabited by lions--here called the Father of the Wilderness. Dr. Barth saw several, as well as a kind of ape about the size of a small boy, squatting in crowds on the lower hills. Beyond, overhung by the mountains of Anderas, is the rocky plain of Tarist, famous among the Arabs, as well as the Kailouees, on account of the remains of a mosque, indicated only by lines of stones on the ground. It was founded by a great saint called Sidi Baghdadi, and is a general resting-place for caravans. The basaltic formation here succeeds the granitic; and the plain is covered with loose black stones, about the size of a child's head. Escaping from this rough ground, the travellers entered a narrow valley, trenched by a broad watercourse, along the sides of which was a thick growth of palm-trees. There are two villages in this wady. Near one of them slaves were seen yoked to a plough, and driven like oxen, by their master. Further south the hoe replaces the plough in preparing the ground. This valley, inhabited by the Imrad (a Targhee tribe), is capable of producing not only ghaseb, but corn, wine, dates, and all kinds of vegetables. Fifty gardens adorn, it is said, the neighbourhood of Ifargen. But, in general, the rich soil is left uncultivated, and is covered by wild and sickly vegetation, which checks the progress of the traveller.
