The doctor’s order was executed. An almost imperceptible breath of air impelled the balloon directly over the prisoner, at the same time that it gently lowered with the contraction of the gas. For about ten minutes it remained floating in the midst of luminous waves, for Ferguson continued to flash right down upon the throng his glowing sheaf of rays, which, here and there, marked out swift and vivid sheets of light. The tribe, under the influence of an indescribable terror, disappeared little by little in the huts, and there was complete solitude around the stake. The doctor had, therefore, been right in counting upon the fantastic appearance of the balloon throwing out rays, as vivid as the sun’s, through this intense gloom. The car was approaching the ground; but a few of the savages, more audacious than the rest, guessing that their victim was about to escape from their clutches, came back with loud yells, and Kennedy seized his rifle. The doctor, however, besought him not to fire. The priest, on his knees, for he had not the strength to stand erect, was not even fastened to the stake, his weakness rendering that precaution superfluous. At the instant when the car was close to the ground, the brawny Scot, laying aside his rifle, and seizing the priest around the waist, lifted him into the car, while, at the same moment, Joe tossed over the two hundred pounds of ballast. The doctor had expected to ascend rapidly, but, contrary to his calculations, the balloon, after going up some three or four feet, remained there perfectly motionless. “What holds us?” he asked, with an accent of terror. Some of the savages were running toward them, uttering ferocious cries. “Ah, ha!” said Joe, “one of those cursed blacks is hanging to the car!” “Dick! Dick!” cried the doctor, “the water-tank!” Kennedy caught his friend’s idea on the instant, and, snatching up with desperate strength one of the water-tanks weighing about one hundred pounds, he tossed it overboard. The balloon, thus suddenly lightened, made a leap of three hundred feet into the air, amid the howlings of the tribe whose prisoner thus escaped them in a blaze of dazzling light. “Hurrah!” shouted the doctor’s comrades. Suddenly, the balloon took a fresh leap, which carried it up to an elevation of a thousand feet. “What’s that?” said Kennedy, who had nearly lost his balance. “Oh! nothing; only that black villain leaving us!” replied the doctor, tranquilly, and Joe, leaning over, saw the savage that had clung to the car whirling over and over, with his arms outstretched in the air, and presently dashed to pieces on the ground. The doctor then separated his electric wires, and every thing was again buried in profound obscurity. It was now one o’clock in the morning. The Frenchman, who had swooned away, at length opened his eyes. “You are saved!” were the doctor’s first words.
