Kennedy's Dreams.--Articles and Pronouns in the Plural¹.--Dick's Insinuations. --A Promenade² over the Map of Africa.--What is contained between two Points of the Compass.--Expeditions now on foot.--Speke and Grant.--Krapf, De Decken, and De Heuglin.

Dr. Ferguson energetically pushed the preparations for his departure, and in person superintended the construction of his balloon, with certain modifications³; in regard to which he observed the most absolute silence. For a long time past he had been applying himself to the study of the Arab language and the various Mandingoe idioms, and, thanks to his talents as a polyglot⁴, he had made rapid progress.

In the mean while his friend, the sportsman, never let him out of his sight--afraid, no doubt, that the doctor might take his departure, without saying a word to anybody. On this subject, he regaled him with the most persuasive⁵ arguments, which, however, did NOT persuade Samuel Ferguson, and wasted his breath in pathetic entreaties⁶, by which the latter seemed to be but slightly moved. In fine, Dick felt that the doctor was slipping through his fingers.

The poor Scot was really to be pitied. He could not look upon the azure⁷ vault⁸ without a sombre terror: when asleep, he felt oscillations that made his head reel; and every night he had visions of being swung aloft at immeasurable heights.

We must add that, during these fearful nightmares, he once or twice fell out of bed. His first care then was to show Ferguson a severe contusion that he had received on the cranium. "And yet," he would add, with warmth, "that was at the height of only three feet--not an inch more--and such a bump as this! Only think, then!"

This insinuation, full of sad meaning as it was, did not seem to touch the doctor's heart.

"We'll not fall," was his invariable reply.
