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.
