“A last effort got us to the top of this lofty summit, 10,000 feet above the sea, where we found a narrow platform strewn with boulders, with big clusters of red and lilac tinted flowers growing in the gaps between the stones. Toilsomely enough, I managed to scramble on to the highest rock, and as I stood on it, there lay before my eyes, for the first time, the mysterious Tibestian chains that no explorer had ever gazed on yet in their majestic entirety. The grandeur and beauty of the sight so far outdid all I had anticipated that I could not turn my eyes from watching the harmonious hues thrown over the landscape by the rays of the declining sun. The intense clearness of the air made it easy to see distinctly the remotest peaks; all around lay long ridges, their successive summits rising and falling in regular points like lace; scattered rocks, deep gorges, dizzy precipices, jagged peaks. Each mountain range, though all were turned by the sun to the purest rose colour, had its distinct shade, brightest in the foreground, softening into mauve as distance melted into distance away to the far horizon. “Eastwards, the Tibestian massifs fell by giant steps whose sharp-angled lines, blurred by the first shadows of the waning day, ran into one another in inextricable tangles; while to the west the mountains bordered an endless plain, a forbidding waste of stones, over which brooded and deepened a gloom that threw into beautiful contrast the rosy-mantled chains whose lofty summits soared into a sky of calm and exquisite blue.” Tearing myself away, not without reluctance, from the dreamy fancies called up by all these glories, I made haste to take a few observations with compass and thermometer and make a few notes. The Tibestian reliefs appeared to me to be included in a right angle, the apex of which is marked by the volcano, and the two sides by the directions W.N.W. and N.N.E.; such being the case, the appearance of Tibesti was totally different from what I had till then supposed it to be, on the strength of the statements put forward by the explorer Nachtigal. The rest of my journey was to afford me the opportunity of unravelling the skeins of the succession of ranges, whose apparent position and extent I could now approximately fix. On September 18, towards noon, we struck camp, to go down again into the plain by the route we had followed on our upward march. While the camels, weary and emaciated, were painfully climbing the slopes of the pass leading out of the volcano, I took a last all-embracing look at this huge crater, 10,000 feet above the sea; few others in the world are so immense, for it is 5 miles wide and 8 miles long, and looks like a gigantic funnel, almost elliptical in outline, 25 miles round and 800 yards deep; on all sides it is shut in by a rampart of unbroken wall, rising sheer almost everywhere for 500 or 600 feet, and which can be got over only at two points, by openings that are very hard to reach.
