“Lastly,” resumed the doctor, “M. de Heuglin, the Austrian vice-consul at Karthoum, has just organized a very important expedition, the first aim of which is to search for the traveller Vogel, who, in 1853, was sent into the Soudan to associate himself with the labors of Dr. Barth. In 1856, he quitted Bornou, and determined to explore the unknown country that lies between Lake Tchad and Darfur. Nothing has been seen of him since that time. Letters that were received in Alexandria, in 1860, said that he was killed at the order of the King of Wadai; but other letters, addressed by Dr. Hartmann to the traveller’s father, relate that, according to the recital of a felatah of Bornou, Vogel was merely held as a prisoner at Wara. All hope is not then lost. Hence, a committee has been organized under the presidency of the Regent of Saxe-Cogurg-Gotha; my friend Petermann is its secretary; a national subscription has provided for the expense of the expedition, whose strength has been increased by the voluntary accession of several learned men, and M. de Heuglin set out from Massowah, in the month of June. While engaged in looking for Vogel, he is also to explore all the country between the Nile and Lake Tchad, that is to say, to knit together the operations of Captain Speke and those of Dr. Barth, and then Africa will have been traversed from east to west.”[1] [1] After the departure of Dr. Ferguson, it was ascertained that M. de Heuglin, owing to some disagreement, took a route different from the one assigned to his expedition, the command of the latter having been transferred to Mr. Muntzinger. “Well,” said the canny Scot, “since every thing is getting on so well, what’s the use of our going down there?” Dr. Ferguson made no reply, but contented himself with a significant shrug of the shoulders. CHAPTER SIXTH. A Servant—match him!—He can see the Satellites of Jupiter.—Dick and Joe hard at it.—Doubt and Faith.—The Weighing Ceremony.—Joe and Wellington.—He gets a Half-crown. Dr. Ferguson had a servant who answered with alacrity to the name of Joe. He was an excellent fellow, who testified the most absolute confidence in his master, and the most unlimited devotion to his interests, even anticipating his wishes and orders, which were always intelligently executed. In fine, he was a Caleb without the growling, and a perfect pattern of constant good-humor. Had he been made on purpose for the place, it could not have been better done. Ferguson put himself entirely in his hands, so far as the ordinary details of existence were concerned, and he did well. Incomparable, whole-souled Joe! a servant who orders your dinner; who likes what you like; who packs your trunk, without forgetting your socks or your linen; who has charge of your keys and your secrets, and takes no advantage of all this!
