ling in
vain, his little white belly exposed to the air.... Morhange picked
him up, looked at him for a moment, and put him back into the little
stream. Shades of St. Francis. Umbrian hills.... But I have sworn not
to break the thread of the story by these untimely digressions.

"You see," Captain Morhange said to me a week later, "that I was right
in advising you to go farther south before making for Shikh-Salah.
Something told me that this highland of Egere was not interesting from
your point of view. While here you have only to stoop to pick up
pebbles which will allow you to establish the volcanic origin of this
region much more certainly than Bou-Derba, des Cloizeaux, and Doctor
Marres have done."

This was while we were following the western pass of the Tidifest
Mountains, about the 25th degree of northern latitude.

"I should indeed be ungrateful not to thank you," I said.

I shall always remember that instant. We had left our camels and were
collecting fragments of the most characteristic rocks. Morhange
employed himself with a discernment which spoke worlds for his
knowledge of geology, a science he had often professed complete
ignorance of.

Then I asked him the following question:

"May I prove my gratitude by making you a confession?"

He raised his head and looked at me.

"Well then, I don't see the practical value of this trip you have
undertaken."

He smiled.

"Why not? To explore the old caravan route, to demonstrate that a
connection has existed from the most ancient times between the
Mediterranean world, and the country of the Blacks, that seems nothing

which have divided so many keen minds; d'Anville, Heeren, Berlioux,
Quatremere on the one hand,--on the other Gosselin, Walckenaer,
Tissit, Vivien, de saint-Martin; you think that that is devoid of
interest? A plague upon you for being hard to please."

"I spoke of practical value," I said. "You won't deny that this
controversy is only the affair of cabinet geographers and office
explorers."

Morhange kept on smiling.

"Dear friend, don't wither me. Deign to recall that your mission was
confided to you by the Ministry of War, while I hold mine on behalf of
the Ministry of Public Instruction. A different origin justifies our
different aims. It certainly explains, I readily concede that to you,
why what I am in search of has n
