“You can easily see, then, that time presses if we are to take part in these exploring labors. And that is not all, since, while some are thus advancing with sure steps to the discovery of the sources of the Nile, others are penetrating to the very heart of Africa.”

“On foot?” said Kennedy.

“Yes, on foot,” rejoined the doctor, without noticing the insinuation. “Doctor Krapf proposes to push forward, in the west, by way of the Djob, a river lying under the equator. Baron de Decken has already set out from Monbaz, has reconnoitred the mountains of Kenia and Kilimandjaro, and is now plunging in toward the centre.”

“But all this time on foot?”

“On foot or on mules.”

“Exactly the same, so far as I am concerned,” ejaculated Kennedy.

“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.
