Much to the boys’ surprise the buffalo paid not the slightest attention to the other animals. It found a place at the pond and began drinking.

“That’s a new one on me,” whispered Bob, and Joe nodded. “Looks like there’d be trouble, with all those different kinds of creatures there at once.”

“You see they have a common interest: to quench their thirst,” explained Mr. Lewis. “In such a case peace reigns.”

But ten minutes later the explorers—and very obviously the animals—heard something that was not so suggestive of peace. It was the deep, vibrating roar of a lion, which seemed to be coming nearer.

The effect was immediate. Uneasiness prevailed among the more harmless animals; some of them turned about and disappeared into the jungle depths, while others pricked up their ears and listened.

But there was no mistaking the distant roar. A lion was abroad stalking for prey.

As the minutes passed, Mr. Lewis and Mr. Holton held their rifles ready for instant action. At every second they feared that the lion would appear. Bob and Joe, although realizing that perhaps their lives were in danger, continuing to film the scene, delighted at the unusualness of the occasion.

Suddenly the explorers’ eyes opened wide, for the thing that they beheld was exceedingly large and powerful.

A great maned lion moved slowly toward the water hole!
