Singular and interesting indeed is the wild scenery in the vicinity of the treacherous oasis of Sultelli. A field of extinct volcanic cones, vomited forth out of the entrails, of the earth, and encircled each by a black belt of vitrified lava, environs it on three sides; and of these, Mount Abida, three thousand feet in height, whose yawning cup, enveloped in clouds, stretches some two and half miles in diameter, would seem to be the parent. Beyond, the still loftier crater of Aiulloo, the ancient landmark of the now decayed empire of Ethiopia, is visible in dim perspective; and looming hazily in the extreme distance, the great blue Abyssinian range towards which the steps of the toil-worn wayfarers were directed--now for the first time visible--arose in towering grandeur to the skies. Overwhelmed by violent subterranean convulsion and commotion, which, reversing the order of things, has again and again altered the former appearance, the face of the country for miles around the base of the larger volcanoes, presents one sheet of lava. Activity would not appear to have extended much beyond the immediate neighbourhood of each; but there is a connection between the whole cluster visible in small lava streams and a vast quantity of volcanic debris, converted into humus, in the adjacent valleys. Yet it is by no means apparent that these alone have contributed to form the present surface, the south-eastern side of the field terminating in much older formation of wacke. Neither would any one of the craters appear to have very lately poured out the fiery stream. Ibrahim Shehem Abli indeed deposed with an oath to having seen Father Abida in flames about twelve years previously; but, on further investigation, there seemed reason to believe that the conflagration he witnessed must have been confined to the long grass with which portions of the steep sides are clothed.
