At length his companions understood him, and took their places at his side.
“And now, Joe,” said the doctor, “throw out some fifty pounds of your ore, there!”
Joe no longer hesitated, although he still felt a fleeting pang of regret. The balloon at once began to ascend.
“It was high time!” said the doctor.
The simoom, in fact, came rushing on like a thunderbolt, and a moment later the balloon would have been crushed, torn to atoms, annihilated. The awful whirlwind was almost upon it, and it was already pelted with showers of sand driven like hail by the storm.
“Out with more ballast!” shouted the doctor.
“There!” responded Joe, tossing over a huge fragment of quartz.
With this, the Victoria rose swiftly above the range of the whirling column, but, caught in the vast displacement of the atmosphere thereby occasioned, it was borne along with incalculable rapidity away above this foaming sea.
The three travellers did not speak. They gazed, and hoped, and even felt refreshed by the breath of the tempest.
About three o’clock, the whirlwind ceased; the sand, falling again upon the desert, formed numberless little hillocks, and the sky resumed its former tranquillity.
The balloon, which had again lost its momentum, was floating in sight of an oasis, a sort of islet studded with green trees, thrown up upon the surface of this sandy ocean.
“Water! we’ll find water there!” said the doctor.
And, instantly, opening the upper valve, he let some hydrogen escape, and slowly descended, taking the ground at about two hundred feet from the edge of the oasis.
In four hours the travellers had swept over a distance of two hundred and forty miles!
The car was at once ballasted, and Kennedy, closely followed by Joe, leaped out.
“Take your guns with you!” said the doctor; “take your guns, and be careful!”
Dick grasped his rifle, and Joe took one of the fowling-pieces. They then rapidly made for the trees, and disappeared under the fresh verdure, which announced the presence of abundant springs. As they hurried on, they had not taken notice of certain large footprints and fresh tracks of some living creature marked here and there in the damp soil.
Suddenly, a dull roar was heard not twenty paces from them.
“The roar of a lion!” said Joe.
“Good for that!” said the excited hunter; “we’ll fight him. A man feels strong when only a fight’s in question.”
“But be careful, Mr. Kennedy; be careful! The lives of all depend upon the life of one.”
But Kennedy no longer heard him; he was pushing on, his eye blazing; his rifle cocked; fearful to behold in his daring rashness. There, under a palm-tree, stood an enormous black-maned lion, crouching for a spring on his antagonist. Scarcely had he caught a glimpse of the hunter, when he bounded through the air; but he had not touched the ground ere a bullet pierced his heart, and he fell to the earth dead.
“Hurrah! hurrah!” shouted Joe, with wild exultation.
Kennedy rushed toward the well, slid down the dampened steps, and flung himself at full length by the side of a fresh spring, in which he plunged his parched lips. Joe followed suit, and for some minutes nothing was heard but the sound they made with their mouths, drinking more like maddened beasts than men.
“Take care, Mr. Kennedy,” said Joe at last; “let us not overdo the thing!” and he panted for breath.
But Kennedy, without a word, drank on. He even plunged his hands, and then his head, into the delicious tide–he fairly revelled in its coolness.
“But the doctor?” said Joe; “our friend, Dr. Ferguson?”
That one word recalled Kennedy to himself, and, hastily filling a flask that he had brought with him, he started on a run up the steps of the well.
But what was his amazement when he saw an opaque body of enormous dimensions blocking up the passage! Joe, who was close upon Kennedy’s heels, recoiled with him.
“We are blocked in–entrapped!”
“Impossible! What does that mean?–”
Dick had no time to finish; a terrific roar made him only too quickly aware what foe confronted him.
“Another lion!” exclaimed Joe.
