BESIDE a patch of bushes was a large wildcat, greedily devouring the remains of a small deer. Most of the deer’s body has been torn to pieces, so that only the head remained intact. There was a terrible stare from the wide eyes that caused Bob to shudder in disgust.

The tiger-cat was evidently very hungry, for it would scarcely bite out one section when it would tear into another, crunching horribly. Occasionally it would shift its position and sample various parts of the body. It finally crouched at the stomach, and in no time stripped the flesh from the bone.

The sight was not wholly to Bob’s liking, but he could not tear himself away. After all, the occasion was not one so terrible. All wild creatures must eat, and this is the only way they know.

Bob lifted his eyes from the feast to the great cat, and for the first time saw how beautifully marked it was. Why had he not noticed that before? Probably because he was much more impressed by the meal. The wildcat’s fur was of a light brown, spotted and barred with black and darker brown. Its abdomen was pure white, and seemed spotlessly clean. It looked about four feet long, exclusive of the tail.

“Doesn’t look very ferocious,” Bob thought, but he knew what would probably happen if the creature were to discover him in its domain.

For several minutes the feast continued, the animal’s hunger seeming to increase rather than lessen.

Suddenly there came a rustling sound from behind a low shrub.

Instantly the cat was on its feet, tail erect, eyes staring.

The rustling sound continued, and a moment later another cat of the same type leaped out into the clearing, took in its surroundings carefully, and then made for the body of the deer.

But it did not get far. A moment later the first tiger-cat crouched itself and sprang at the invader’s throat. Then a terrific combat took place, the memory of which was to remain with Bob for many years to come.

The creatures thrashed constantly about, each trying to inflict a death wound. They growled horribly, and occasionally one would cry out in pain. Sometimes they reared up on hind legs, biting and tearing fearfully. Then again they would be on top of each other, stamping and tearing to the height of their ability. For nearly five minutes the fight continued, and by now it was evident that the invader was getting the worst of it. Instead of being on the offensive it slunk back, trying in vain to ward off the assaults of its enemy. Suddenly it fell back, as a vital part was pierced. The first tiger-cat had won.

A few more minutes were spent in awaiting any further movements from the defeated, but as none came the victor resumed its feast.

“All over,” Bob muttered to himself. “A swell fight, too. I wouldn’t have missed it for anything. But say! This fellow would be a fine specimen for Dad and Mr. Lewis. I wonder if I can plug him. Don’t think the dead one will be of much use to them, it’s so badly mauled.”

The moon was still shining down brightly, and it was nearly as light as day. This was both an advantage and a disadvantage. True, it would be much easier to get a good aim at the animal, but the light would make Bob much more easily seen. Still he resolved to chance it.

Gripping his rifle firmly, he parted the bushes and rose to his feet. But the slight commotion caused the tiger-cat to turn about, and rage came into its eyes as they lighted on the youth. What was this new type of creature that had come to interrupt the feast?

Bob raised his rifle to his shoulder and awaited a chance to fire an effective shot. But none came. The great cat crouched to spring.

“I’ve got to get him,” said Bob, gritting his teeth.

Then, as the animal launched itself into the air, the youth took rapid but careful aim and fired.

The bullet sped true, entering the open mouth.

The tiger-cat fell at the boy’s feet, twitched about for a moment, and then lay still.

“Hurrah!” Bob cried, exulted beyond words. “I got him. And what a fine specimen.”

The rifle shot had aroused the rest of the expedition, and they came running out, wondering what was meant.

“What’s up?” demanded Mr. Holton, as he first caught sight of his son.

“Plenty,” Bob replied and led them to the bodies of the wildcats.

Everyone cried out in surprise and amazement at sight of the beasts.

“Ocelots,” pronounced Mr. Lewis. “I didn’t know that they were this common. How did you happen to come across them?”

Bob was obliged to relate the entire experience. He told of how he had come across one of the creatures at the body of the deer, of the thrilling combat that took place when the other ocelot arrived, and of shooting the survivor. The party listened with breathless interest, and even the Indians demanded a translation.

“An unusual happening,” said Professor Bigelow, looking at Bob in admiration and wishing that he had been present.

“Takes old Bob to do it,” smiled Joe. “And that required some nerve, too. The first wild animal he’s ever met.”

“It’s a case where the first is one of the most savage,” remarked Mr. Lewis, directing a glance at the creature’s sharp canine teeth. “The ocelot is next only to the jaguar in ferocity and daring.”

“Not much left of the deer he was feasting on,” observed Joe. “I suppose he would have left little more than the skeleton if Bob hadn’t so rudely interrupted him.”

Mr. Holton and Mr. Lewis procured knives and began the task of skinning the creatures. It was believed that both could be used, as the one that had been previously killed was not as badly mauled as Bob had thought.

In a short time the skinning was completed, and they again retired for the night, Bob remaining throughout the remainder of his watch. Nothing more happened that night, however, and they awoke the next morning to witness a beautiful sunrise. Breakfast was soon over, and then began the task of breaking camp.

“Let’s hurry,” urged Professor Bigelow. “We want to cover twenty miles today, if possible.”

“And we will if rapids don’t bar our way,” said Mr. Lewis.

Soon the belongings were packed in the boats, and they started on up the river. Meanwhile Bob and Joe were taking motion pictures quite often and were always on the lookout for new sights. Many times did they regret that they had been unable to film Bob’s experience of the night before.

The men kept their time occupied in writing notes and collecting specimens, which were growing in number hourly. Already there was an abundance of game. Monkeys quite often were crowded in the trees, birds of brilliant plumage were more numerous, various small animals darted out, and once Joe caught a glimpse of a wild pig running through the underbrush.

“When are we going ashore?” asked Bob. “Looks like here is a good chance to get some specimens.”

“It undoubtedly is,” Mr. Holton returned. “And we would try our luck now if Professor Bigelow were not anxious to find a strange tribe of Indians that’s reputed to be somewhere in this region. When we locate it we can stop and stay at one spot as long as the professor chooses, for game will probably be abundant, and we will have the chance to get scores of specimens.”

That day they made nearly twenty-five miles, and all were delighted that no rapids loomed up to hinder them.

“There’s nothing that puts you at more inconvenience than rapids,” said Professor Bigelow, as they sought out a place to camp for the night.

They found the spot they wanted beside a rocky knoll, not far from the river. There was a small open space a short distance away, and to this the party made. Again preparations were made for the night, and then the evening meal was prepared.

“Let’s turn in early,” suggested Mr. Holton, after they had finished eating. “The three Indians in the back boat complained that one of the clamps for an oar is loose, and it may take quite a while to repair it. For that reason we must be up early in the morning.”

The clamp, they discovered later, had been split through, making it necessary to carve out a new one. To do this was not easy, for suitable wood had to be cut and measurements taken. All told, there was a delay of over three hours.

“Now let’s go,” urged Professor Bigelow, his patience almost exhausted.

Day after day the miles were laid behind them in both a pleasant and disagreeable manner. In times when treacherous rapids offered a hindrance, they struggled unflinchingly, often knee deep in the water or mud. But there were chances for relaxation, when there was nothing to do but take it easy in the high seats of the boats. Bob and Joe could not fully realize that they were not in a dream but that this was the real thing—a wild, untamed land in the very heart of vast Amazonia.

“It’s great, Joe, old boy,” said Bob, when over a week had passed. “I’ve often visualized this expedition, but my expectations are far surpassed.”

One morning when they were paddling swiftly along, Professor Bigelow uttered a cry of delight and pointed to the bank.

“Indians!” he cried excitedly. “At last we’ve found a band of Indians!”
