"It is too dangerous to try to swim," he clicked. "In some places the branches of the trees on this side almost touch branches of the trees on the other side. If we keep on the path, maybe we can find a place where it would be safe to climb over." The path they were on turned and followed the river.
They walked on for a few minutes. Baba stopped again, sniffing the air.
"I don't like it," he clicked. "The leopards are close again."
They moved forward cautiously, but when minutes passed and no attack came they walked with more confidence. The magic formula of clicks seemed to be working. Though nothing bothered them, they knew from rustling noises and from cries that animals were all about them. Nowhere could they find a place where the tree branches made a bridge across the river. Nowhere could they find a place of refuge.
The trail began to lead away from the river toward a little hill that stood in black outline against the almost darkened sky. Big Venus fireflies had begun to come out, sparkling like so many blue stars. The two weary travelers followed the path, hoping it would lead back to the river. It ended completely at the base of the small rocky hill.
So tired he almost wanted to cry, Johnny sat down in the middle of the path. Then he noticed a spot of deeper darkness among the rocks. He jumped to his feet.
"Hey, Baba," he said, "it looks like a cave! Come on!"
The two of them hurried forward. A nice comfortable cave was just what they were looking for! They were within a few yards of the cave, when they heard a crashing noise from the underbrush and the pad of soft footsteps.
A leopardess leaped in front of them, cutting them off from the cave. The big cat growled low, and two cubs scuttled through the entrance. The leopardess sat back on her haunches in the mouth of the cave, her eyes two gold-green lights burning in the dark green of the late twilight. Slightly larger than an Earth lion, the Venus sabre-tooth leopard is coal black, marked with golden spots. Her two tusk-like fangs show why leopards are among the most deadly fighters of all the Venus animals.
Baba began clicking again.
