All these mountains and rocky hills lie on the right side of the river. This coincides with what has been said to us previously, and the plastic formation of the mountains themselves shews that the river does not break through from E. or S.E., and the natives are right when they place the sources of the White Stream to the _south_. On the left side of the river rises first, S.W. 3″ to W., Mount Lòngi, at two hours distant; Mount Lobèk, with a rocky head S.W. 28″ to W., three hours; the flat, round Loffoni S.W. 30″ to W. four hours; Mount Bio S.W. 60″ to W., some eight hours distant, ascending again to a considerable height; Mount Korèk, already known to us, on the ground softly rising from the river; it is one hour and a half from the river, entirely of a rocky nature, intersected in manifold parts by steep disrupt walls of rocks, similar to quarries. All its peaks not only lie in the distance, where the whole mountain appears like a terrace, but also near at hand, in equal horizontal lines, from W. to 75″ to N. It is perhaps not more than six hundred feet high, and it is the mountain that principally affords iron, although all the heights are said to contain the same. As I distinguished previously Mount Nerkanjin on the left side of the Nile, by its height, so the mountains seem to increase generally on this side in height, as also the country from the shore to S.W. gradually ascends. Mount Konnopi or Kunobih appears W. by N., at a distance of from nine to ten hours, of light-coloured rocks, without any vegetation. It forms likewise a mountain group, with its six or seven peaks, which fall away tolerably steeply in convex lines, and separate one from the other. The high points of this group are of equal form, and may rise to two hundred feet relative height. Behind this mountain and Korèk, a mountain-chain projecting on both sides of Korèk, which stretches itself for about an hour in length, extends in an undulating form, and loses itself to S. This chain is called Kugelù, and I calculate its distance at being at least twenty hours. To N.W. 73″ towards N. lies Mount Lokùn, about two to two and a half hours distant, with a gentle slope of small height, and to N. the Nerkanjin already known to us, some eight to nine hours distant.
