vast, mysterious country, now
thrown open on all sides to the investigations of science.
On the north, the young Duveyrier was exploring Sahara,
and bringing the chiefs of the Touaregs to Paris. Under
the inspiration of the French Government, two expeditions
were preparing, which, descending from the north, and
coming from the west, would cross each other at Timbuctoo.
In the south, the indefatigable Livingstone was
still advancing toward the equator; and, since March,
1862, he had, in company with Mackenzie, ascended the
river Rovoonia. The nineteenth century would, assuredly,
not pass, contended the doctor, without Africa having
been compelled to surrender the secrets she has kept
locked up in her bosom for six thousand years.
But the interest of Dr. Ferguson's hearers was excited
to the highest pitch when he made known to them, in
detail, the preparations for his own journey. They took
pleasure in verifying his calculations; they discussed
them; and the doctor frankly took part in the discussion.
As a general thing, they were surprised at the limited
quantity of provision that he took with him; and one day
one of the officers questioned him on that subject.
"That peculiar point astonishes you, does it?" said
Ferguson.
"It does, indeed."
"But how long do you think my trip is going to last?
Whole months? If so, you are greatly mistaken. Were
it to be a long one, we should be lost; we should never
get back. But you must know that the distance from
Zanzibar to the coast of Senegal is only thirty-five
hundred—say four thousand miles. Well, at the rate of two
hundred and forty miles every twelve hours, which does
not come near the rapidity of our railroad trains, by
travelling day and night, it would take only seven days to
cross Africa!"
"But then you could see nothing, make no geographical
observations, or reconnoitre the face of the country."
"Ah!" replied the doctor, "if I am master of my
balloon—if I can ascend and descend at will, I shall stop
when I please, especially when too violent currents of air
threaten to carry me out of my way with them."
"And you will encounter such," said Captain Bennet.
"There are tornadoes that sweep at the rate of more than
two hundred and forty miles per hour."
"You see, then, that with such speed as that, we could
cross Africa in twelve hours. One would rise at Zanzibar,
and go to bed at St. Louis!"
"But," rejoined the officer, "could any balloon withstand
the wear and tear of such velocity?"
"It has happened before," replied Ferguson.
"And the balloon withstood it?"
"Perfectly well. It was at the time of the coronation
of Napoleon, in 1804. The aeronaut, Gernerin, sent up a
balloon at Paris, about eleven o'clock in the evening. It
bore the following inscription, in letters of gold: 'Paris,
25 Frimaire; year XIII; Coronation of the Emperor Napoleon
by his Holiness, Pius VII.' On the next morning,
the inhabitants of Rome saw the same balloon soaring
above the Vatican, whence it crossed the Campagna, and
finally fluttered down into the lake of Bracciano. So you
see, gentlemen, that a balloon can resist such velocities."
"A balloon—that might be; but a man?" insinuated Kennedy.
"Yes, a man, too!—for the balloon is always motionless
with reference to the air that surrounds it. What
moves is the mass of the atmosphere itself: for instance,
one may light a taper in the car, and the flame will not
even waver. An aeronaut in Garnerin's balloon would not
have suffered in the least from the speed. But then I
have no occasion to attempt such velocity; and if I can
anchor to some tree, or some favorable inequality of the
ground, at night, I shall not fail to do so. Besides, we
take provision for two months with us, after all; and there
is nothing to prevent our skilful huntsman here from furnishing
game in abundance when we come to alight."
"Ah! Mr. Kennedy," said a young midshipman, with
envious eyes, "what splendid shots you'll have!"
"Without counting," said another, "that
