These parties were scarcely quieted when others took their place, urging their pretensions to our acknowledgments; and we had just started the next day when Bóro Serki-n-turáwa despatched, underhand, my smart friend the Tawáti ʿAbd el Káder, with full instructions to give me a lecture on his boundless power and influence in the country which we were fast approaching. I was aware of this before, and knew that, in our situation as unprotected travellers in a new country, we ought to have secured his friendly disposition from the beginning; but the means of the expedition being rather limited, Mr. Richardson had made it a principle never to give till compelled by the utmost necessity, when the friendly obligation connected with the present was, if not destroyed, at least greatly diminished. The structure of the valley soon became irregular, and the character of the country more desolate, a circumstance which seems to be expressed by its name, Ikadémmelrang. All was granite in a state of the utmost disintegration, and partly reduced to gravel, while detached cones were rising in all directions. Marching along over this dreary and desolate country, we reached, at half past two in the afternoon, after a gradual and almost imperceptible ascent, the highest level of the desert plain, from whence the isolated rocky cones and ridges look like so many islands rising from the sea. A sketch which I made of one of these mounts will give an idea of their character. [Illustration] After a march of twelve hours and a half, which I would have gladly doubled, provided our steps had been directed in a straight line towards the longed-for regions of Negroland, we encamped on hard ground, so that we had great difficulty in fixing the pegs of our tents. The sky was overcast with thick clouds; but our hopes of a refreshing rain were disappointed. [Sidenote: Thursday, August 15th.] The character of the country continued the same, though the weather was so foggy that the heights at some distance were quite enveloped, and became entirely invisible. This was a sure indication of our approaching tropical climes. After a march of three miles and a half, the ground became more rugged for a short time, but was soon succeeded by a gravelly plain. The sky had become thickly clouded; and in the afternoon a high wind arose, succeeded, about two o’clock, by heavy rain, and by distant thunder, while the atmosphere was exceedingly heavy, and made us all feel drowsy.
