The darkness was profound. Nothing could be seen of the Trans-Saharan Railway constructing on the plans of Duponchel—a long ribbon of iron destined to bind together Algiers and Timbuktu by way of Laghouat and Gardaia, and destined eventually to run down into the Gulf of Guinea. Then the “Albatross” entered the equatorial region below the tropic of Cancer. Six hundred miles from the northern frontier of the Sahara she crossed the route on which Major Laing met his, death in 1846, and crossed the road of the caravans from Morocco to the Sudan, and that part of the desert swept by the Tuaregs, where could be heard what is called “the song of the sand.” a soft and plaintive murmur that seems to escape from the ground. Only one thing happened. A cloud of locusts came flying along, and there fell such a cargo of them on board as to threaten to sink the ship. But all hands set to work to clear the deck, and the locusts were thrown over except a few hundred kept by Tapage for his larder. And he served them up in so succulent a fashion that Frycollin forgot for the moment his perpetual trances and said, “these are as good as prawns.” The aeronef was then eleven hundred miles from the Wargla oasis and almost on the northern frontier of the Sudan. About two o’clock in the afternoon a city appeared in the bend of a large river. The river was the Niger. The city was Timbuktu. If, up to then, this African Mecca had only been visited by the travelers of the ancient world Batouta, Khazan, Imbert, Mungo Park, Adams, Laing, Caillé, Barth, Lenz, on that day by a most singular chance the two Americans could boast of having seen, heard, and smelt it, on their return to America—if they ever got back there. Of having seen it, because their view included the whole triangle of three or four miles in circumference; of having heard it, because the day was one of some rejoicing and the noise was terrible; of having smelt it, because the olfactory nerve could not but be very disagreeably affected by the odors of the Youbou-Kamo square, where the meatmarket stands close to the palace of the ancient Somai kings. The engineer had no notion of allowing the president and secretary of the Weldon Institute to be ignorant that they had the honor of contemplating the Queen of the Sudan, now in the power of the Tuaregs of Taganet. “Gentlemen, Timbuktu!” he said, in the same tone as twelve days before he had said, “Gentlemen, India!” Then he continued, “Timbuktu is an important city of from twelve to thirteen thousand inhabitants, formerly illustrious in science and art. Perhaps you would like to stay there for a day or two?” Such a proposal could only have been made ironically. “But.” continued he, “it would be dangerous among the Negroes, Berbers, and Foullanes who occupy, it—particularly as our arrival in an aeronef might prejudice them against you.”
