Thus reasoning, he looked around for some means of getting over the ravine. A number of vines grew across, and he determined to test them and if they were strong enough, to use them as a rope for getting across.

The vines appeared to be as firm as a cable, and without giving the matter a second thought he launched himself forth and started to the other side of the cut in the forest.

He had progressed less than two yards when he felt one end of the vines giving way. He tried to turn back, but it was too late, and down he went.

Some heavy bushes broke his fall somewhat, but he continued to go down and down, until with a dull thud he landed on a mass of soft dirt. He was unharmed and soon arose to his feet, to gaze around in fresh dismay.

He had landed in an opening or cave, and presently went down into it still further. Then, as he picked himself up, he heard a sudden low growl, that filled him with fear. He strained his eyes and made out a small animal, which proved to be the cub of an ocelot.

He followed its course to a litter of leaves and straining his glance in that direction made out two other cubs.

They were too small to be dangerous. Plum had told him that there were very few ocelots in that vicinity and these rather cowardly, unless attacked or enraged.

Jack looked hurriedly around. The parent ocelot was not in evidence. The baby cub he had stumbled over, however, was making a great outcry, and our hero decided he would not linger any longer than was necessary.

He got under the hole he had fallen through. It was not accessible by climbing, for the walls of the cave were perfectly perpendicular and came nowhere near the central aperture.

Jack reached up and caught at the dangling end of the broken vine. It sustained one hard pull, but, as he set his full weight, it tore up roots and all, bringing down a shower of dirt and gravel.
