So at it he went, in one of the wildest jigs that ever was seen, twisting, turning, and jerking himself in all directions; dancing with his hands, dancing with his body, dancing with his knees, dancing with his feet; describing the most fearful contortions and extravagant evolutions; throwing himself into incredible attitudes; grimacing beyond all belief, and, in fine giving his savage admirers a strange idea of the style of ballet adopted by the deities in the moon.

Then, the whole collection of blacks, naturally as imitative as monkeys, at once reproduced all his airs and graces, his leaps and shakes and contortions; they did not lose a single gesticulation; they did not forget an attitude; and the result was, such a pandemonium of movement, noise, and excitement, as it would be out of the question even feebly to describe. But, in the very midst of the fun, Joe saw the doctor approaching.

The latter was coming at full speed, surrounded by a yelling and disorderly throng. The chiefs and sorcerers seemed to be highly excited. They were close upon the doctor’s heels, crowding and threatening him.

Singular reaction! What had happened? Had the sultan unluckily perished in the hands of his celestial physician?

Kennedy, from his post of observation, saw the danger without knowing what had caused it, and the balloon, powerfully urged by the dilation of the gas, strained and tugged at the ropes that held it as though impatient to soar away.

The doctor had got as far as the foot of the ladder. A superstitious fear still held the crowd aloof and hindered them from committing any violence on his person. He rapidly scaled the ladder, and Joe followed him with his usual agility.

“Not a moment to lose!” said the doctor. “Don’t attempt to let go the anchor! We’ll cut the cord! Follow me!”

“But what’s the matter?” asked Joe, clambering into the car.

“What’s happened?” questioned Kennedy, rifle in hand.

“Look!” replied the doctor, pointing to the horizon.
