_Sunday, October 6._—Starting early, we soon reached a more open country, which to the eye seemed to lean towards Mount Bághzen; but this was only an illusion, as appeared clearly from the direction of the dry watercourses, which all ran from east to west-south-west. On our right we had now Mount Ágata, which has given its name to the village mentioned above as lying at its foot. Here the fertility of the soil seemed greatly increased, the herbage becoming more fresh and abundant, while numerous talhas and abísgas adorned the country. Near the foot of the extensive mountain group of Bághzen, and close to another mountain called Ajúri, there are even some very favoured spots, especially a valley called Chímmia, ornamented with a fine date-grove, which produces fruit of excellent quality. As we entered the meandering windings of a broad watercourse we obtained an interesting view of Mount Belásega. The plain now contracted, and, on entering a narrow defile of the ridges, we had to cross a small pass, from the top of which a most charming prospect met our eyes. [Illustration] A grand and beautifully shaped mountain rose on our right, leaving, between its base and the craggy heights, the offshoots of which we were crossing, a broad valley running almost east and west, while at the eastern foot of the mountain a narrow but richly adorned valley wound along through the lower rocky ground. This was Mount Abíla, or Bíla, which is at once one of the most picturesque objects in the country of Aír, and seems to bear an interesting testimony to a connection with that great family of mankind which we call the Semitic; for the name of this mountain, or rather of the moist and “green vale” at its foot (throughout the desert, even in its most favoured parts, it is the valley which generally gives its name to the mountain), is probably the same as that of the well-known spot in Syria from which the province of Abilene has been named.
