At half-past five, on the morning of the 27th, we left the village of Lantégué, to cross the chain of mountains of that name, proceeding to the S.E. Some of these mountains appeared to be three hundred and fifty and four hundred fathoms above the elevated plain on which we were. I observed some very beautiful granite of a whitish-grey colour. We passed not far from a little village, where the Foulahs were tending their cattle. As we crossed the chain of mountains, I saw the poor negroes, with loads on their heads, leaping from precipice to precipice, and every moment expected to see them fall into the yawning gulphs beneath. From the depths proceeds a dull murmur, produced by the numerous springs which rise among the mountains. They fall into the plain beneath, where they form a sort of river. When we descended we saw nothing but mountains on every side, though none appeared so high as those which I had seen in the morning. At the part where we crossed the chain, it extends in the direction from N.E. to S.S.E. I did not perceive any snow. I saw some very beautiful black granite, both in strata three or four feet thick and in blocks. I also saw grey, white, and pale rose-coloured granite of a very beautiful grain. We travelled on in an eastern direction until we reached the banks of the Kakiriman, a little river which runs from north to south, over a bed of granite. Its current is very rapid and its width may be about seventy or eighty ordinary paces. I could trace with my eye the course of this river to the distance of three or four miles and along that space its breadth did not appear to vary. At the point where we forded it the water came up to our waists. Having deviated a little from the course taken by my companions, I was carried to some distance by the current, and the water came up to my arm-pits. The negroes, perceiving me, called out, desiring me to make the best of my way back again. They all exclaimed with one voice, _La allah il allah, Mahommed rasoul oullahi_, and appeared very much alarmed at my danger. A little further down, the river becomes deep, and, as I could not have contended against the current, I should have sunk. At length, by managing to ascend a little, I gained the left bank in safety, but my baggage was completely wet. About eleven in the morning we halted not far from the banks of the river, in a place covered with hillocks of black sand, on which grew numbers of large bamboos. We seated ourselves beneath the trees. The poor slaves were dreadfully fatigued, and though I had no load to carry I was almost as tired as they. I bought some cagnan, a sort of bread which I have already described. This was the first food I had tasted during the whole of the day. Several Foulahs made me little presents. The negroes told me that the river we had just crossed was the Rio Pongo. Want of rice obliged us to pack up our baggage and proceed to Pandeya, a little village inhabited by Foulah herdsmen. On our way we met two negroes,
