Doctor Ferguson’s first care was to take his bearings by stellar observation, and he discovered that he was scarcely twenty-five miles from Senegal.

“All that we can manage to do, my friends,” said he, after having pointed his map, “is to cross the river; but, as there is neither bridge nor boat, we must, at all hazards, cross it with the balloon, and, in order to do that, we must still lighten up.”

“But I don’t exactly see how we can do that?” replied Kennedy, anxious about his fire-arms, “unless one of us makes up his mind to sacrifice himself for the rest, --that is, to stay behind, and, in my turn, I claim that honor.”

“You, indeed!” remonstrated Joe; “ain’t I used to--”

“The question now is, not to throw ourselves out of the car, but simply to reach the coast of Africa on foot. I am a first-rate walker, a good sportsman, and--”

“I’ll never consent to it!” insisted Joe.

“Your generous rivalry is useless, my brave friends,” said Ferguson; “I trust that we shall not come to any such extremity: besides, if we did, instead of separating, we should keep together, so as to make our way across the country in company.”

“That’s the talk,” said Joe; “a little tramp won’t do us any harm.”

“But before we try that,” resumed the doctor, “we must employ a last means of lightening the balloon.”

“What will that be? I should like to see it,” said Kennedy, incredulously.

“We must get rid of the cylinder-chests, the spiral, and the Buntzen battery. Nine hundred pounds make a rather heavy load to carry through the air.”

“But then, Samuel, how will you dilate your gas?”

“I shall not do so at all. We’ll have to get along without it.”

“But--”

“Listen, my friends: I have calculated very exactly the amount of ascensional force left to us, and it is sufficient to carry us every one with the few objects that remain. We shall make in all a weight of hardly five hundred pounds, including the two anchors which I desire to keep.”

“Dear doctor, you know more about the matter than we do; you are the sole judge of the situation. Tell us what we ought to do, and we will do it.”

“I am at your orders, master,” added Joe.

“I repeat, my friends, that however serious the decision may appear, we must sacrifice our apparatus.”

“Let it go, then!” said Kennedy, promptly.

“To work!” said Joe.

It was no easy job. The apparatus had to be taken down piece by piece. First, they took out the mixing reservoir, then the one belonging to the cylinder, and lastly the tank in which the decomposition of the water was effected. The united strength of all three travellers was required to detach these reservoirs from the bottom of the car in which they had been so firmly secured; but Kennedy was so strong, Joe so adroit, and the doctor so ingenious, that they finally succeeded. The different pieces were thrown out, one after the other, and they disappeared below, making huge gaps in the foliage of the sycamores.

“The black fellows will be mightily astonished,” said Joe, “at finding things like those in the woods; they’ll make idols of them!”

The next thing to be looked after was the displacement of the pipes that were fastened in the balloon and connected with the spiral. Joe succeeded in cutting the caoutchouc jointings above the car, but when he came to the pipes he found it more difficult to disengage them, because they were held by their upper extremity and fastened by wires to the very circlet of the valve.

Then it was that Joe showed wonderful adroitness. In his naked feet, so as not to scratch the covering, he succeeded by the aid of the network, and in spite of the oscillations of the balloon, in climbing to the upper extremity, and after a thousand difficulties, in holding on with one hand to that slippery surface, while he detached the outside screws that secured the pipes in their place. These were then easily taken out, and drawn away by the lower end, which was hermetically sealed by means of a strong ligature.

The Victoria, relieved of this considerable weight, rose upright in the air and tugged strongly at the anchor-rope.

About midnight this work ended without accident, but at the cost of most severe exertion, and the trio partook of a luncheon of pemmican and cold punch, as the doctor had no more fire to place at Joe’s disposal.

Besides, the latter and Kennedy were dropping off their feet with fatigue.

“Lie down, my friends, and get some rest,” said the doctor. “I’ll take the first watch; at two o’clock I’ll waken Kennedy; at four, Kennedy will waken Joe, and at six we’ll start; and may Heaven have us in its keeping for this last day of the trip!”
