"Then you see nothing strange and solemn in this wonderful stream? nothing in the weird civilization crouching at the feet, vainly looking to the head of its master hidden in the clouds? nothing in the echoing footsteps of nations passing down its banks to their destiny? nothing in the solemn, unbroken silence brooding over the fountain whence sprang this marvellous river, to bear precious gifts to thousands and millions, and again retreat unknown? Is there no mystery in unsolved questions, no wonder in miracles, no awe in inapproachability?"

"I see," said he, steadily, "that a river of some thousand miles long has run through a country peopled by contented, or ignorant, or barbarous people, none of whom, of course, would take the slightest interest in tracing the river; that the dangers that have guarded the marvellous secret, as you call it, are not intrinsic to the secret itself, but are purely accidental and contingent There is no more reason why the source of the Nile should not be found than that of the Connecticut; so I do not see that it is really at all inapproachable or awful."

"What in the world, Herndon," cried I, in desperation, "what in the name of common sense ever induced you to set out on this expedition? What do you want to discover the source of the Nile for?"

He answered with the ready air of one who has long ago made up his mind confidently on the subject he is going to speak about.

"It has long been evident to me, that civilization, flowing in a return current from America, must penetrate into Africa, and turn its immense natural advantages to such account, that it shall become the seat of the most flourishing and important empires of the earth. These, however, should be consolidated, and not split up into multitudinous missionary stations. If a stream of immigration could be started from the eastern side, up the Nile for instance, penetrating to the interior, it might meet the increased tide of a kindred nature from the west, and uniting somewhere in the middle of Soudan, the central point of action, the capital city could be founded there, as a heart for the country, and a complete system of circulation be established. By this method of entering the country at both sides simultaneously, of course its complete subjugation could be accomplished in half the time that it would take for a body of emigrants, however large, to make headway from the western coast alone. About the source of the Nile I intend to mark out the site for my city, and then"——

"And call it," I added, "Herndonville."

"Perhaps," he said, gravely. "At all events, my name will be inseparably connected with the enterprise; and if I can get the steamboat started during my lifetime, I shall make a comfortable fortune from the speculation."

"What a gigantic scheme!" I exclaimed.

"Ah," he said, complacently, "we Americans don't stick at trifles."

"Oh, marvellous practical genius of America!" I cried, "to eclipse Herodotus and Diodorus, not to mention Bruce and Cailliaud, and inscribe Herndonville on the arcanum of the Innermost! If the Americans should discover the origin of evil, they would run up penitentiaries all over the country, modelled to suit 'practical purposes.'"
