‘When the sun appears above the forests of the east be ye all on the border of the evil desert, for if ye fail I will crush you to atoms.’ The voice ceased, the ground closed, and the smoke cleared away. There was no time for us to consult; the desert lay ten miles off, and it was now midnight. We immediately set off with the Duke of York at our head. We reached the desert about 4 A.M., and there we stopped. Far off to the east the long black line of gloomy forests skirted the horizon. To the north the Mountains of the Moon seemed a misty girdle to the plain of Dahomey; to the south the ocean guarded the coasts of Africa; before us to the west lay the desert. In a few minutes we saw a dense vapour rise from the sands, which gradually collecting took the form of a Genius larger than any of the giants. It advanced towards us and cried with a loud voice: ‘Follow me!’ We obeyed and entered the desert. After we had travelled a long time, about noon the Genius told us to look around. We were now about the middle of the desert. Nothing was to be seen far or near but vast plains of sand under a burning sun and cloudless sky. We were dreadfully fatigued and begged the Genius to allow us to stop a little, but he immediately ordered us to proceed. We therefore began our march again and travelled a long way, till the sun went down and the pale moon was rising in the east. Also a few stars might now be dimly seen, but still the sands were burning hot, and our feet were very much swollen. At last the Genius ordered us to halt and lie down. We soon fell asleep. We had slept about an hour when the Genius awoke us and ordered us to proceed. The moon had now risen and shone brightly in the midst of the sky—brighter far than it ever does in our country. The night-wind had somewhat cooled the sands of the desert, so that we walked with more ease than before; but now a mist arose which covered the whole plain. Through it we thought we could discern a dim light. We now likewise heard sounds of music at a great distance. As the mist cleared away the light grew more distinct till it burst upon us in almost insufferable splendour. Out of the barren desert arose a palace of diamonds, the pillars of which were ruby and emerald illuminated with lamps too bright to look upon. The Genius led us into a hall of sapphire in which were thrones of gold. On the thrones sat the Princes of the Genii. In the midst of the hall hung a lamp like the sun. Around it stood genii and fairies whose robes were of beaten gold sparkling with diamonds. As soon as their chiefs saw us they sprang up from their thrones, one of them seizing Arthur Wellesley and exclaiming: ‘This is the Duke of Wellington!’ Arthur Wellesley asked her why she called him the Duke of Wellington.
