Having attended to the safety of the little "bibi," the negro again lowered the rope for Stas, but he, like a captain who is the last to leave a sinking ship, ordered Mea to go ahead of him.

Kali did not at all need to pull her as in a moment she climbed the rope with skill and agility as if she were the full sister of a chimpanzee. For Stas it was considerably more difficult, but he was too well-trained an athlete not to overcome the weight of his own body together with the rifle and a score of cartridges with which he filled his pockets.

In this manner all four found themselves in the tree. Stas was so accustomed to think of Nell in every situation that now he was occupied, above all, in ascertaining whether she was not in danger of falling, whether she had sufficient room and whether she could lie down comfortably. Satisfied in this respect, he began to wrack his brains as to how to protect her from the rain. But for this there was no help. It would have been easy to construct during the daytime some kind of roof over her head, but now they were enveloped in such darkness that they could not see each other at all. If the storm at last passed away and if they succeeded in starting the fire again, they might dry Nell's dress! Stas, with despair, thought that the little girl, soaked to the skin, would undoubtedly on the following day suffer from the first attack of fever.

He feared that towards the morning, after the storm, it would be as cool as it was on the previous night. Thus far the wind was rather warm and the rain as though heated. Stas was surprised at its persistence as he knew that the more strongly a storm raged the shorter was its duration.

After a long time the thunder abated and the buffets of the wind weakened, but the rain continued to fall, less copious, indeed, than before, but so heavy and thick that the leaves did not afford any protection against it. From below came the murmur of water as if the whole jungle were transformed into a lake. Stas thought that in the ravine certain death would have awaited them. Immense sorrow possessed him at the thought of what might have become of Saba, and he did not dare to speak of him to Nell. He, nevertheless, had a slight hope that the intelligent dog would find a safe haven among the rocks projecting above the ravine. There was not, however, a possibility of going to him with any aid.

They sat, therefore, one beside the other amid the expanding boughs, drenched and waiting for the day. After the lapse of a few more hours the air began to cool and the rain finally ceased. The water too flowed down the slope to a lower place as they could not hear a splash or a murmur. Stas had observed on the previous days that Kali understood how to stir up a fire with wet twigs, so it occurred to him to order the negro to descend and try whether he would not succeed this time. But at the moment in which he turned to him something happened which froze the blood in the veins of all four.

The deep silence of the night was rent suddenly by the squeaking of horses, horrible, shrill, full of pain, fears, and mortal dismay. Some mischief was afoot in the darkness; there resounded short rattlings in the throat, afterwards hollow groans, a snorting, a second squeak yet more penetrating, after which all was quiet.

"Lions, great Master! Lions killing horses!" whispered Kali.

There was something so horrible in this night attack, in the superior force of the monsters, and in the sudden slaughter of the defenseless animals that Stas for a time was struck with consternation, and forgot about the rifle. What, after all, would it have availed him to shoot in such darkness? Unless for this, that those midnight assassins, if the flash and report should frighten them, would abandon the horses already killed, and start after those which were scared away and had run from the camp as far as their fettered legs would permit them.

Stas' flesh began to creep at the thought of what would have happened if they had remained below. Nell, nestling close to him, shook as if she already were suffering the first attack of fever, but the tree at least protected them from an attack of lions. Kali plainly had saved their lives.
